\u2605 The Most Installation-Versatile Right-Angle Planetary Gearbox \u2014 Axial Space Saving AND No Bore Machining, Combined in One Unit<\/div>\n

EP-ZDWF is the Korea Ever-Power precision planetary gearbox that combines two installation advantages simultaneously: the 30\u201350% axial depth reduction<\/strong> of the right-angle bevel input (from the EP-ZDWE series right angle planetary gearbox<\/a>) and the no-bore-required flat-plate mounting<\/strong> of the square output flange (from the EP-ZDF serija<\/a>). For Korean machine builders working with welded frames, aluminium extrusion structures, or laser-cut plate assemblies where both axial space and bore machining capability are constrained, EP-ZDWF eliminates both restrictions in a single product.<\/p>\n<\/div>\n

The EP-ZDWF series right-angle square-flange precision planetary gearbox and servo gear reducer<\/strong> from Korea Ever-Power is the intersection of the EP-ZDWE and EP-ZDF series in a single unit. It carries the right-angle 90\u00b0 bevel input stage of EP-ZDWE \u2014 positioning the servo motor perpendicular to the output shaft to reduce total axial depth \u2014 and replaces the round output housing of EP-ZDWE with the square output flange (\u25a160\u2013\u25a1175 mm) of EP-ZDF, enabling direct flat-plate bolt-down mounting without a precision bore. All internal gear stages, torque ratings, backlash specifications, efficiency values, and lifetime lubrication characteristics are identical to EP-ZDWE.<\/p>\n

Korean OEM machine builders who design machines around laser-cut flat-plate chassis or welded box-section frames \u2014 common in Korean AGV manufacturers, collaborative robot frame builders, and compact conveyor system integrators \u2014 find EP-ZDWF the optimal specification when the design brief simultaneously constrains both available axial depth behind the drive axis and the available machine shop operations for boring.<\/p>\n

When Both Constraints Apply \u2014 EP-ZDWF Is the Correct Specification<\/h3>\n
\n
\n

\u2460 Welded-Frame Compact Machines \u2014 No Boring, No Axial Space<\/strong><\/p>\n

Korean compact special-purpose machine builders who fabricate machine frames from welded structural steel box section face both constraints simultaneously: the welded frame has no machined bore and there is limited depth behind the axis for a motor to protrude inline. A laser-cut plate welded into the frame provides a flat mounting surface that accepts EP-ZDWF’s square flange with 4 drill-and-tap holes; the right-angle bevel input places the motor within the available frame depth rather than projecting beyond it. EP-ZDWF solves the welded-frame installation with no post-weld machining operation and no extension of the machine envelope beyond the frame boundary.<\/p>\n<\/div>\n

\n

\u2461 AGV & Mobile Robot Flat-Plate Chassis \u2014 Laser-Cut Structure, Minimal Depth<\/strong><\/p>\n

Korean AGV manufacturers typically build drive module frames from laser-cut aluminium or steel flat-plates assembled into a box structure. The drive axis is mounted through a plate, and the available chassis height (often 100\u2013140 mm for low-profile AGVs) makes an inline motor impossible at any useful torque level. EP-ZDWF-60 or EP-ZDWF-80 mounts through the bottom plate with the square flange bolted to the plate face \u2014 4 laser-cut holes in the plate cut simultaneously with the plate profile. The motor exits upward into the chassis interior. Total drive depth is the gearbox L1 only (150\u2013184.5 mm for 60\u201380 frame, 1-stage), fitting within the chassis height with clearance for the motor body height within the chassis internal volume.<\/p>\n<\/div>\n

\n

\u2462 Aluminium Extrusion Profile Machines \u2014 Bracket-Free Direct Mounting<\/strong><\/p>\n

Korean automation system builders using 80\u00d780 mm or 120\u00d7120 mm aluminium profile framing systems for pick-and-place, dispensing, and assembly machines use EP-ZDWF by mounting the square flange directly to a profile end-plate or gusset bracket. The T-slot profile cannot provide a precision bore, but a flat plate attached to the profile accepts EP-ZDWF’s square flange bolted flat-face. The right-angle input allows the motor to exit along the profile axis rather than perpendicular to it, keeping the overall machine cross-section within the profile grid without requiring a custom oversized extrusion or a projecting motor overhang.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Step-by-Step Installation Procedure<\/h3>\n

\"Postupak<\/p>\n

\n
\n
\n
1<\/div>\n

Confirm Input Direction, Flange Size & Model Code<\/strong><\/p>\n<\/div>\n

Verify the EP-ZDWF model code includes the motor input direction (left\/right\/up\/down), frame size (60\u2013160), square flange size D7 (\u25a160\u2013\u25a1175), and input flange Q3 matching the servo motor front face. Confirm L12 (total height with motor input) fits within your machine section. Check that the square flange size and bolt-hole pattern are compatible with your machine plate before installation.<\/p>\n<\/div>\n

\n
\n
2<\/div>\n

Prepare the Machine Plate \u2014 4 Holes Only<\/strong><\/p>\n<\/div>\n

Drill 4 mounting holes in the machine plate at the correct PCD (see EP-ZDF dimension table for matching frame size \u2014 D8 and D9 values). No precision bore is required. Ensure the mounting surface flatness is within 0.02 mm. For laser-cut plates, confirm the bolt-hole positions are included in the cutting file at the plate design stage \u2014 no secondary machining needed. Clean the surface to remove burrs before mounting.<\/p>\n<\/div>\n

\n
\n
3<\/div>\n

Motor Coupling \u2014 Perpendicular Bevel Input<\/strong><\/p>\n<\/div>\n

Insert the servo motor shaft fully into the perpendicular bevel input bore until the motor face contacts the input flange squarely. Tighten S-type locking screws evenly in a cross pattern. Verify no axial gap between motor face and input flange \u2014 if the motor shaft is shorter than the bore depth, use a spacer ring. The clamping input works with or without a motor shaft keyway.<\/p>\n<\/div>\n

\n
\n
4<\/div>\n

Square Flange Mounting \u2014 4-Bolt Pattern<\/strong><\/p>\n<\/div>\n

Place the square flange face against the machine plate, aligning the 4 through-bolt holes with the plate hole pattern. Insert class 8.8 bolts (10.9 recommended for high-cycle applications), hand-tighten, verify full face contact, then torque evenly in cross pattern. Use thread-locking compound (medium-strength) for vibration-prone applications. Verify motor body has clearance in the perpendicular direction before final torquing.<\/p>\n<\/div>\n

\n
\n
5<\/div>\n

Output Shaft, Load & Clearance Check<\/strong><\/p>\n<\/div>\n

Connect load coupling to h7 output shaft D4 using standard procedure. Confirm radial load at shaft centre (L\/2) does not exceed max radial force (e.g. 900 N for 80-frame). Manually rotate through full output revolution and confirm motor body clears all machine structure in the perpendicular direction. Route servo motor cables parallel to the machine travel axis, using a cable chain with adequate loop length to accommodate any axis movement range without cable tension.<\/p>\n<\/div>\n

\n
\n
6<\/div>\n

No-Load Run-In, Bolt Re-torque & Bevel Warm-Up<\/strong><\/p>\n<\/div>\n

Run no-load for 30 minutes at \u226450% rated input speed. After run-in: (1) re-check 4 flange bolt torque values \u2014 thermal cycling may cause slight joint settling; (2) a light bevel stage hum during the first 10\u201315 minutes is normal run-in behaviour; (3) verify system backlash via servo drive feedback. Record as installation baseline. The sealed lifetime lubrication requires no further servicing after this run-in procedure.<\/p>\n<\/div>\n<\/div>\n

\u26a0 Installation Cautions:<\/strong> Motor input direction is fixed at manufacture \u2014 specify correctly when ordering. Square flange face must have full contact with the machine plate \u2014 a gap concentrates bolt load and risks flange fatigue. Do not apply axial force to the bevel input shaft during motor installation. Never exceed 4,500 rpm input speed. The sealed housing has no grease port \u2014 do not add lubricant externally.<\/p>\n<\/div>\n

\n

\u2714 Zero Maintenance \u2014 Both Stages Covered:<\/strong> The factory-sealed lifetime lubrication covers both the bevel input stage and the planetary gear stages in a single housing. No separate bevel gear oil, no scheduled lubrication, no re-greasing required over the 20,000-hour rated life. Re-check the 4 flange mounting bolts at the first 5,000-hour inspection alongside the visual lip seal check \u2014 this is the only periodic maintenance action for EP-ZDWF.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

Applications \u2014 EP-ZDWF Right-Angle Square-Flange Planetary Gearbox in Korean Compact Platform Designs<\/h2>\n
\n
\n

Low-Profile AGV Drive Modules \u2014 Laser-Cut Chassis, Minimal Height<\/h3>\n

Korean AGV manufacturers building low-profile warehouse AMRs with a chassis height of 100\u2013150 mm use EP-ZDWF-60 and EP-ZDWF-80 for drive wheel servo reductions. The square flange bolts to the bottom chassis plate through 4 laser-cut holes \u2014 no boring, no secondary machining \u2014 and the motor exits upward into the chassis interior through the available 100\u2013150 mm chassis height. Total gearbox axial depth below the chassis plate is the L1 dimension only (150\u2013184.5 mm for 60\u201380 frame, 1-stage), which places the drive wheel at the correct height relative to the floor. Korean AGV manufacturers in Hwaseong, Incheon, and Ansan report EP-ZDWF enabling low-profile AMR designs that compete directly with purpose-built AGV gear units at a fraction of the custom tooling cost.<\/p>\n<\/div>\n

Welded-Frame Compact Special-Purpose Machines<\/h3>\n

Korean special-purpose machine builders fabricating welded steel box frames for dedicated assembly, testing, or material handling equipment use EP-ZDWF where both the axial space and the bore machining capability are unavailable. A laser-cut insert plate welded into the frame provides the flat mounting surface for EP-ZDWF’s square flange. The right-angle bevel input positions the motor within the frame depth rather than projecting beyond the frame boundary. This is particularly common in Korean EV battery module assembly machines, where the machine footprint is tightly constrained by the production cell layout and bore machining of welded assemblies is impractical.<\/p>\n<\/div>\n

\n

Aluminium Profile Automation Cells \u2014 No Secondary Machining<\/h3>\n

Korean automation system integrators building reconfigurable assembly and dispensing cells from 80\u00d780 or 120\u00d7120 mm aluminium profile framing specify EP-ZDWF for servo drive axes on the profile structure. The square flange bolts to an end-plate or gusset attached to the profile \u2014 no bore possible in the profile itself \u2014 and the motor exits along the profile section axis, keeping the overall drive package within the profile grid without oversized brackets. For the round-flange right-angle variant used with custom-bored profile blocks, see the EP-ZDWE series right angle planetary gearbox<\/a>.<\/p>\n<\/div>\n

\n

Collaborative Robot Wrist \u2014 Square-Flange Plate-Mount Structure<\/h3>\n

Korean collaborative robot manufacturers using laser-cut carbon-fibre or aluminium plate assemblies for robot arm structure (rather than cast or machined arm links) use EP-ZDWF for wrist roll and wrist pitch joints. The square flange bolts to the plate assembly without requiring a precision bore that would be impractical in thin-plate composite structures. The right-angle input routes the motor parallel to the arm link, controlling the wrist outer diameter to the gearbox body size (\u25a160\u2013\u25a190 mm). For applications where the arm structure can accommodate a round bore, the EP-ZDWE round-flange version planetary gearbox<\/a> provides equivalent performance.<\/p>\n<\/div>\n

\n

Narrow-Profile Packaging Machine Bracket Modules<\/h3>\n

Korean packaging machinery OEMs designing servo-actuated filling and sealing stations for narrow-pitch carousel or chain-conveyor packaging lines use EP-ZDWF-60 and EP-ZDWF-80 for bracket-mounted servo actuators where both the bracket footprint and the available depth behind the mounting plate are constrained. The square flange enables the entire motor-gearbox module to be replaced as a bolted assembly in a single maintenance operation \u2014 without removing the bracket from the machine or performing any bore-alignment procedure. The right-angle bevel input routes the motor along the machine structure rather than projecting it into the operator access zone.<\/p>\n<\/div>\n

\n

Solar Tracker Slew Drives \u2014 Flat-Plate Mounting, Lateral Motor<\/h3>\n

Korean solar tracker manufacturers designing single and dual-axis trackers with flat steel tube or angle-iron mounting structures for utility-scale solar farms in Korea, Vietnam, and Southeast Asia use EP-ZDWF-120 and EP-ZDWF-160 for the azimuth and elevation axis drives. The square flange bolts directly to a flat mounting plate welded onto the tracker torque tube assembly \u2014 no machined bore on the field-fabricated steel structure. The right-angle bevel input routes the servo motor laterally along the torque tube rather than projecting it perpendicular to the tracker panel surface, reducing wind load on the drive assembly and keeping the motor within the tracker’s structural shadow. IP54 sealing and the \u221225\u00b0C to +90\u00b0C operating range cover Korean outdoor tracker operating conditions year-round.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
