When a machine axis must turn 90\u00b0 between the servo motor and the load, the conventional approach is an external right-angle bevel gearbox or a worm reducer bolted onto a standard gearbox. Both introduce additional components, additional backlash sources, and efficiency losses. The EP-TMR<\/strong> integrates the spiral bevel 90\u00b0 turn and the helical planetary reduction into a single sealed housing. Seven frame sizes (042\u2013220 mm) cover output torques from 17 N\u00b7m to 2,000 N\u00b7m with gear ratios i=3 to i=200 in single and dual stage configurations. The motor input direction \u2014 left, right, up, or down \u2014 is fixed at manufacture, so the correct direction must be specified at ordering.<\/p>\n

Six Engineering Advantages That Make EP-TMR the Compact Right-Angle Solution<\/h2>\n

\"EP-TMR<\/p>\n

\n
\n
\u2460 One Housing \u2014 No External Right-Angle Adapter<\/div>\n

Adding a right-angle bevel reducer to a standard planetary gearbox introduces a second housing, a second bearing system, a second lubrication requirement, and a second source of backlash. EP-TMR integrates both the helical planetary reduction and the spiral bevel 90\u00b0 turn in a single forged-alloy housing with one sealed grease fill. The assembled unit is shorter, lighter, and has fewer wear components than a two-box solution at the same torque rating.<\/p>\n<\/div>\n

\n
\u2461 Spiral Bevel \u2014 Quiet 90\u00b0 Direction Change<\/div>\n

The bevel stage uses ground spiral bevel gears \u2014 not straight bevel gears \u2014 with a 25\u201335\u00b0 helix angle and 58\u201362 HRC surface hardness. Spiral bevel contact sweeps progressively across the tooth face rather than impacting instantaneously; the result is 4\u20136 dB lower bevel stage noise than straight bevel at the same tooth load. EP-TMR noise at 3,000 rpm ranges \u226461\u201374 dB(A) across frames \u2014 typically 5 dB above the equivalent EP-TM inline at the same frame.<\/p>\n<\/div>\n

\n
\u2462 Planet Carrier to Bevel Pinion \u2014 Zero-Coupling Shaft<\/div>\n

The planet carrier and bevel pinion shaft are machined as one integrated component \u2014 the planetary output flows directly into the bevel pinion without an intermediate coupling. Eliminating this coupling removes the runout that would accumulate at the carrier-to-pinion joint in an assembled design. The bevel stage noise and backlash are lower than competing right-angle units that use a separate coupling between the planetary carrier and the bevel pinion shaft.<\/p>\n<\/div>\n

\n
\u2463 Four Motor Input Directions \u2014 Fixed at Manufacture<\/div>\n

The bevel stage housing can be specified with the motor input pointing left, right, upward, or downward relative to the output shaft. This is set by the bevel housing orientation at manufacture and cannot be changed in the field. The flexibility eliminates custom-shafting arrangements that otherwise add length, alignment error, and maintenance complexity when a motor must exit a machine frame in a specific direction. Specify the required input direction \u2014 L, R, U, or D \u2014 in the model code at time of order.<\/p>\n<\/div>\n

\n
\u2464 i=3\u2013200 \u2014 Wider Ratio Range Than EP-TM Inline<\/div>\n

EP-TMR dual-stage reaches i=200, versus i=100 for EP-TM. The extended range is particularly relevant for right-angle conveyor drives, slew ring actuators, and slow-speed solar tracker drives where the combination of 90\u00b0 direction change and high ratio is needed in the same unit. At i=200, a 3,000 rpm motor drives the output at 15 rpm \u2014 appropriate for heavy rotary table positioning and worm gear pre-stages where the EP-TMR adds the high-efficiency primary reduction before a self-locking worm final stage.<\/p>\n<\/div>\n

\n
\u2465 Axial Depth Saving vs Inline + Right-Angle Adapter<\/div>\n

A conventional inline gearbox plus an external right-angle bevel adapter has a combined axial length equal to both units in series. The EP-TMR’s single-housing design is shorter \u2014 the 90\u00b0 turn is inside the gearbox, not outside it. For machine columns, robot joint housings, and conveyor side frames where axial depth behind the output shaft is constrained, EP-TMR reduces the overall drive assembly depth by the length of the external bevel adapter that would otherwise be required. For installations where the motor must also fold sideways to save depth, see the EP-TNR right-angle flange series<\/a>.<\/p>\n<\/div>\n<\/div>\n

 <\/p>\n<\/section>\n

\n

Output Shaft Load Engineering \u2014 The Critical Difference Between TMR and Inline Units<\/h2>\n

\"workshop<\/p>\n

The EP-TMR’s right-angle output shaft carries a more complex load state than the equivalent inline EP-TM output shaft. This complexity demands careful engineering \u2014 and is the reason that EP-TMR permissible radial force specifications are not identical to the EP-TM values at the same frame size.<\/p>\n

\n
\n

Internal pre-load from the bevel stage:<\/strong> In normal operation, the spiral bevel gear mesh generates a separation force, a tangential force, and an axial force on the bevel shaft. These internal forces are present regardless of any external load applied to the output shaft end. The EP-TMR bearing system is designed with pre-loaded angular contact bearings that neutralise these internal forces \u2014 but they consume a portion of the bearing’s rated capacity. This is why the permissible external radial force at the EP-TMR output shaft is slightly lower than at the EP-TM output shaft of the same frame.<\/p>\n

Overhang position factor Kb<\/sub>:<\/strong> When the external radial load is applied at the shaft centre (x = L\/2xL), the full permissible radial force applies. As the load is applied further from the bearing (x increasing beyond L\/2xL), the bending moment on the output shaft increases and the permissible radial force decreases according to the position factor Kb<\/sub>. The relationship is not linear \u2014 refer to the Korea Ever-Power position load coefficient chart or the radial load calculation guide for the full chart and calculation methodology.<\/p>\n

EP-TMR<\/strong> (this page): square body housing, same flange as EP-TM. Best for replacing inline units or when machine frame uses square-body gearbox mounting.<\/p>\n

EP-TNR<\/a><\/strong>: round flange output. Better for applications needing larger-diameter output flange, higher moment capacity at the output interface, or direct robot flange mounting.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n

EP-TMR in Korean Industry \u2014 Where Right-Angle Output Solves a Real Design Problem<\/h2>\n

\"Testovacie<\/p>\n

\n
\n
\u2460 Korean CNC Tool Turret Indexing<\/div>\n

Korean lathe and turning centre tool turrets require the servo motor to be positioned perpendicular to the turret rotation axis to clear the spindle envelope. EP-TMR060\/090 at i=10\u201325 is the standard configuration \u2014 the motor mounts laterally, the turret indexes on the output shaft axis. The low backlash (P1 \u22646 arcmin) allows encoder-based position confirmation without additional reference sensor hardware.<\/p>\n<\/div>\n

\n
\u2461 Korean Packaging Machine Folder Drives<\/div>\n

Korean pharmaceutical blister packaging and carton folding machines use EP-TMR to drive folding arms and sealing platens from a servo positioned behind or beside the machine frame \u2014 not in line with the motion. The 90\u00b0 output eliminates a coupling-and-shaft extension assembly, reducing accumulated angular error in the folding mechanism and simplifying machine frame design.<\/p>\n<\/div>\n

\n
\u2462 Korean AGV Wheel Corner Module<\/div>\n

Korean e-commerce logistics AGVs with Mecanum or omni wheels use TMR042\/060 at the wheel corner to drive from a vertically-mounted motor. The compact body of the TMR042 (109 mm total length, \u25a142 square section) fits within the constrained wheel-corner envelope that a standard inline unit cannot. The i=5\u201310 single-stage ratio maintains high efficiency appropriate for battery-powered AGV operation.<\/p>\n<\/div>\n

\n
\u2463 Korean Semiconductor FOUP Transfer Robot<\/div>\n

Front-opening unified pod transfer robots in Korean fab corridors must fit within the SEMI E84 footprint standard. The TMR060\/090 allows mounting the servo motor parallel to the robot base plate \u2014 reducing the robot’s frontal depth by the motor body length compared to an inline configuration. The high-precision P1 version ensures FOUP positioning accuracy within the \u00b11 mm SEMI standard requirement.<\/p>\n<\/div>\n

\n
\u2464 Korean Food Processing Conveyor Side Drive<\/div>\n

Korean food processing lines (kimchi, ready-meal, packaged snack) use TMR090\/115 to drive conveyor belt head drums from the side wall of the conveyor frame. The motor mounts vertically on the conveyor side face \u2014 keeping the top of the conveyor clear for product handling \u2014 while the output shaft connects directly to the drum shaft. IP65 rating handles food processing washdown environments.<\/p>\n<\/div>\n

\n
\u2465 Korean Screw Conveyor and Agitator Side Drive<\/div>\n

Korean grain dryers, chemical agitators, and concrete mixer plants use TMR115\/142\/180 at i=25\u2013100 to drive horizontal screw conveyors from a perpendicular motor. The high-ratio dual-stage (i=100\u2013200) accommodates very slow screw conveyor speeds (5\u201330 rpm) from standard induction motors. For these high-cycle low-speed applications, the TMR’s sealed-grease construction eliminates the oil-bath maintenance that worm reducers require in the same configuration.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

Backlash grade note \u2014 EP-TMR vs EP-TM: <\/strong>
\nThe EP-TMR P1 specification of \u22646 arcmin is slightly wider than the EP-TM P1 specification of \u22643 arcmin. This is not a quality difference \u2014 it reflects the addition of the bevel stage’s own contribution to total system backlash. At the output shaft, both are measured using the same standard method (see backlash guide \u2192). If your application requires \u22643 arcmin at the output despite the right-angle configuration, specify the EP-TNR<\/a> or contact Korea Ever-Power for the TMR ultra-precision option.<\/span><\/div>\n<\/section>\n

Frequently Asked Questions \u2014 EP-TMR Series<\/h2>\n

\n

Ot\u00e1zka<\/span>
\nCan I replace my existing EP-TM inline gearbox with an EP-TMR at the same frame size without changing the motor adapter plate?<\/h3>\n

Yes \u2014 the motor adapter plate (connecting plate) is identical between EP-TM and EP-TMR at every frame size. The motor adapter bolt circle, pilot bore, and register dimensions are shared across the entire EP-TM\/TMR family. When changing from inline to right-angle, you keep the motor, motor adapter plate, and motor shaft coupling \u2014 only the gearbox body and output section change. The output side of the machine will need to accommodate the 90\u00b0 change in shaft orientation, but the motor side installation is a direct swap. Confirm the output shaft diameter and keyway dimensions are identical between your current EP-TM and the EP-TMR before ordering \u2014 these are generally the same but should be verified on the dimensional drawing for your specific model and ratio.<\/p>\n<\/div>\n

\nThe EP-TMR efficiency is \u226595% for single-stage. What causes the ~2% efficiency reduction compared to the EP-TM (\u226597%)?<\/h3>\n

The 2% efficiency difference is the friction loss in the spiral bevel gear stage. The bevel gear pair always meshes at 1:1 ratio \u2014 it redirects direction without changing speed \u2014 but the meshing process itself dissipates approximately 1.5\u20132% of transmitted power as heat regardless of the transmitted torque level. This loss is inherent to the bevel gear mechanism and cannot be eliminated by design. The spiral bevel geometry minimises it (straight bevel pairs lose 3\u20135% in the same configuration) but does not eliminate it. For continuous high-power Korean industrial drives where this 2% matters financially, see the efficiency ROI calculation guide to quantify the annual energy cost of the bevel stage at your specific operating conditions.<\/p>\n<\/div>\n

Ot\u00e1zka<\/span>
\nFor a Korean CNC machine feed axis with a rack-and-pinion drive, should I use EP-TMR or a standard EP-TM with an L-bracket?<\/h3>\n

The EP-TMR eliminates the L-bracket entirely \u2014 the gearbox itself performs the direction change with higher precision than a separate bracket and coupling can achieve. An L-bracket introduces at least one additional shaft coupling and two additional bearing sets, each adding a small angular error and a failure point. The EP-TMR performs the same direction change internally with the spiral bevel stage, maintaining sub-3-arcmin total system backlash from the motor shaft to the pinion. For a rack-and-pinion axis where the pinion is mounted on the EP-TMR output shaft, the output shaft radial load from the rack contact force must be checked against the overhang-corrected permissible radial force using the position factor Kb. At high overhang distances, the EP-TNR<\/a> with its larger-diameter output flange provides higher radial load capacity in the same right-angle configuration.<\/p>\n<\/div>\n

\n

Ot\u00e1zka<\/span>
\nKorean food processing facilities require regular high-pressure washdown. Can the EP-TMR withstand this environment without additional sealing?<\/h3>\n

The EP-TMR is rated IP65 as standard \u2014 protected against low-pressure water jets from any direction per IEC 60529. This covers standard Korean food processing washdown using cleaning hoses at typical pressures (up to approximately 30 kPa). For Korean KFDA-compliant food facilities that use high-pressure steam cleaning or chemical spray at pressures above 30 kPa, IP65 may not be sufficient and the EP-TMR should be positioned in a location away from direct high-pressure spray, or covered during cleaning operations. IP67 rated right-angle gearboxes (immersion rated) are available on the Korea Ever-Power EP-TNR series<\/a> with the IP67 option for the most demanding Korean food and beverage hygiene zone applications.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

EP-TMR090 P1 i=20 on a side-drive conveyor head where the motor had to exit the machine frame laterally \u2014 no space inline. Previous solution used a right-angle worm reducer at the same position, which consumed 70% efficiency and ran at 65\u00b0C housing temperature in summer. EP-TMR090 efficiency \u226595% dropped that to 43\u00b0C steady-state. Also eliminated the quarterly oil change on the worm. 18 months in three-shift operation, zero maintenance events. Korea Ever-Power confirmed the motor adapter for our Yaskawa SGMGV-09A same day.<\/p>\n

EP-TMR115 P1 i=25 for a horizontal milling machine Z-axis where the servo motor had to point toward the rear of the machine rather than downward. The 90\u00b0 output freed up 160 mm of vertical headroom that allowed us to increase the Z-axis travel. Spiral bevel noise at 3,000 rpm was completely acceptable \u2014 \u226468 dB as rated. Four input direction options saved us from a custom shafting arrangement. 12 months on the production line, backlash unchanged versus delivery certificate.<\/p>\n

EP-TMR142 P2 i=40 dual-stage for the base rotation (J1) of a heavy-payload spot welding robot. The 90\u00b0 output let us mount the motor vertically inside the base column instead of protruding rearward, reducing the robot’s floor footprint by 220 mm depth. At 3\u00d7 rated torque (T\u2082max = 1,950 N\u00b7m) during weld gun clamp the gearbox handled the impulse across 36,000 cycles per year without measurable backlash growth. Received the delivery certificate \u2014 actual measured value 7.2 arcmin, well within P2 \u226410 arcmin spec.<\/p>\n

\u2605 The Same Helical Precision as EP-TM \u2014 With the Motor Rotated 90\u00b0<\/div>\n

EP-TMR adds a ground spiral bevel gear stage to the EP-TM<\/a> planetary core, redirecting the output 90\u00b0 while keeping the helical planetary’s torque density and low noise. Four motor input directions \u2014 left, right, up, or down \u2014 let you route the motor wherever the machine layout requires. The cost: +3 arcmin backlash and \u22122% efficiency versus EP-TM at the same frame.<\/p>\n<\/div>","protected":false},"featured_media":789,"comment_status":"open","ping_status":"closed","template":"","meta":{"_et_pb_use_builder":"","_et_pb_old_content":"","_et_gb_content_width":""},"product_brand":[],"product_cat":[963],"product_tag":[],"class_list":["post-785","product","type-product","status-publish","has-post-thumbnail","product_cat-high-precision-planetary-gearbox","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/planetary-gearboxes.com\/sk\/wp-json\/wp\/v2\/product\/785","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/planetary-gearboxes.com\/sk\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/planetary-gearboxes.com\/sk\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/planetary-gearboxes.com\/sk\/wp-json\/wp\/v2\/comments?post=785"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/planetary-gearboxes.com\/sk\/wp-json\/wp\/v2\/media\/789"}],"wp:attachment":[{"href":"https:\/\/planetary-gearboxes.com\/sk\/wp-json\/wp\/v2\/media?parent=785"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/planetary-gearboxes.com\/sk\/wp-json\/wp\/v2\/product_brand?post=785"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/planetary-gearboxes.com\/sk\/wp-json\/wp\/v2\/product_cat?post=785"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/planetary-gearboxes.com\/sk\/wp-json\/wp\/v2\/product_tag?post=785"}],"curies":[{"name":"pracovn\u00fd list","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
