EP-AB系列标准方形法兰高精度直列行星齿轮箱（EP-AB042至EP-AB220）

这 EP-AB series high-precision inline planetary gearbox is Korea Ever-Power's broadest high-precision planetary gearbox general-purpose precision product — an inline unit with a standard square output flange that addresses eleven frame sizes from EP-AB042 to EP-AB220 and covers three distinct backlash grades in a single product family. The P0 grade (≤1 arcmin single-stage) brings sub-arcminute positioning to semiconductor handling, optical positioning, and precision measurement applications. The P1 grade (≤3 arcmin) serves the mainstream servo automation and CNC market. The P2 grade (≤5 arcmin) covers standard automation with broader cost-performance requirements — all from the same family, same installation dimensions, same motor adapter plates.

Single-stage efficiency of ≥97% and an operating temperature range of −10 °C 至 +90 °C extend the EP-AB's reach into environments beyond the standard precision planetary range — cold-room logistics, outdoor machinery, and high-ambient-temperature industrial cells. Standard IP65 dust and water protection, with IP67 as an option, means the EP-AB can be specified in washdown food processing lines, outdoor solar tracker drives, and humid semiconductor fab environments without waterproofing adapters or secondary enclosures.

Packaging Machine Servo Axes — P1, High Speed

Korean flexible packaging machines running at 100–200 cycles per minute require inline planetary gearboxes that combine ≤3 arcmin backlash for consistent film registration with ≥97% efficiency to minimise motor heat in tight enclosures. Frames 060 and 090 at 5:1 to 15:1 cover the cross-seal jaw drive, film feed roll, and register correction axis requirements of Korean VFFS packaging OEMs.

Outdoor Solar Tracker Drives — IP65, −10 °C

Korea's growing utility-scale solar installations require gear reducers that operate through Korean winters (−10 °C and below) without special low-temperature lubrication. EP-AB's standard −10 °C lower operating limit, combined with IP65 weather protection, allows year-round outdoor tracker operation. For tracker installations in environments subject to sustained water immersion or high-pressure steam cleaning, the EP-AE large flange planetary gearbox with optional IP67 provides the upgrade path within the Korea Ever-Power precision range on Korean installations without seasonal maintenance intervention or heated enclosures for the drive units.

EV Battery Module Assembly — P1, High Cycle

Korean EV battery module assembly systems operate at high cycle rates with frequent direction reversals — the operating condition where backlash directly affects cell alignment accuracy. The 090 and 115 frames at P1 serve the rotary positioning axes of battery stacking and bonding machines maintain cell-to-cell alignment within the tight dimensional tolerances required for prismatic and pouch cell module assembly in Korean gigafactories.

CV Joint DriveShafts

When the EP-AB output shaft cannot be coaxial with the driven load — offset rotary table assemblies, dual-motor 4th-axis configurations, or flexible linkage between gearbox and workholding — precision CV joint drive shafts transmit torque through angular and parallel offsets without backlash accumulation. Compatible with EP-AB output shaft diameters across the 042–220 frame range.

蜗轮减速器

For vertical EP-AB output axes carrying gravity loads — column positioners, hoist mechanisms, and tilting fixtures — a downstream self-locking worm gear reducer holds the load on servo power-off without a separate electromagnetic brake. Worm stages also extend the reduction ratio beyond EP-AB's maximum 100:1 two-stage output where the application requires a lower output speed.

农业齿轮箱

For Korean agricultural automation — seeder head drives, fertiliser spreader mechanisms, and harvester conveyor systems — where EP-AB precision servo control connects to downstream PTO-driven bevel and spiral-bevel agricultural gearboxes. Korea Ever-Power supplies the complete drive train from servo motor through EP-AB planetary stage to the agricultural gearbox output.

EP-AB060 at P0 (≤1 arcmin) for the theta axis of a 300 mm wafer handler in our EUV lithography tool. We previously used a European P1 unit and had to accept ±2 arcmin positional uncertainty at the end-effector. The P0 grade cut that to under ±0.8 arcmin measured at the wafer edge — enough to pass our placement spec without active correction. The IP65 rating also survived our IPA spray cleaning validation without any seal degradation over 18 months of operation.

EP-AB090 P1 for the A-axis rotary table on our 5-axis machining centre. We run a lot of titanium aerospace components where the cutting force reversal creates high backlash loading cycles. At 22 months and 6 machines, zero backlash drift beyond the initial run-in. The ≥97% efficiency let us reduce the A-axis motor from 2.2 kW to 1.5 kW — the power savings paid for the motor downgrade within 8 months. Korea Ever-Power's Korean technical team confirmed the inertia ratio calculation in one day, which saved us a week vs our previous overseas supplier.

EP-AB090 P1 for shoulder and elbow joints on 6-axis food handling robots operating in a cold-room at −8 °C. Our previous units (rated to 0 °C) required a warm-up cycle before production start — a 20-minute daily delay. EP-AB's standard −10 °C rating eliminated the warm-up requirement entirely: robots start immediately on the morning shift. The IP65 rating passes our HACCP daily washdown with high-pressure hot water. 19 months, 12 robots, zero gearbox-related downtime.

EP-AB115 P1 at 50:1 for the rotary positioning axis of our prismatic cell stacking machine — stacks 48 cells per module at 12 cycles per minute. The P1 ≤3 arcmin backlash keeps our cell-to-cell alignment within ±0.15 mm at the end of the 48-cell stack. We tested P2 (≤5 arcmin) first and the stack cumulative error at cell 48 was outside our tolerance. P1 solved it. The two-stage ratio 50:1 was available off-the-shelf — competitors' products required a 45:1 or 60:1 which gave us wrong output speed. 14 months, three-shift production, no accuracy drift observed.

问What is the practical positioning difference between P0, P1, and P2 at the workpiece?

Backlash appears as a dead zone when the motor reverses direction — the output shaft does not move until the backlash is taken up. At a radius of 300 mm from the gearbox output shaft axis: P0 (≤1 arcmin) gives a dead zone of ≤0.087 mm at the workpiece; P1 (≤3 arcmin) gives ≤0.26 mm; P2 (≤5 arcmin) gives ≤0.44 mm. For reference, a typical CNC machining tolerance of ±0.01 mm requires positioning repeatability far better than even P0 — so in CNC applications, the relevant specification is usually the full servo loop repeatability, not gearbox backlash alone. For non-servo applications where backlash directly determines positioning error, these numbers apply directly.

问Can I operate EP-AB below −10 °C with a different lubricant?

The standard series grease supports −10 °C to +90 °C. For applications requiring operation below −10 °C — Korean mountain sites, extreme cold-chain environments, or cryogenic-adjacent processes — Korea Ever-Power can supply EP-AB with a low-temperature grease option. This is a factory specification, not a field modification; specify the minimum operating temperature at order time. Contact our Korean application team to confirm the low-temperature grease specification and any torque derating that applies at very low temperatures.

问What does the "A" suffix mean in frame codes like EP-AB090A?

The "A" suffix denotes an alternative input flange geometry — a different adapter plate arrangement at the motor connection end for specific motor shaft and flange configurations that do not fit the standard input bore geometry of the base frame. The gear train, output shaft dimensions, backlash specification, efficiency, and output flange are identical between EP-AB090 and EP-AB090A. When ordering, provide your motor brand and model number to Korea Ever-Power and we will confirm whether the standard or A-suffix configuration is required for your motor.

问Is EP-AB geometrically interchangeable with Apex Dynamics AB, Neugart PLE, or Stöber series?

EP-AB is designed to be geometrically interchangeable with the major European and Asian precision inline planetary gearbox families used in the Korean machine building market — same output flange dimensions, same bolt-circle geometry, same motor adapter plate system. In most cases, EP-AB can substitute as a drop-in replacement. However, "interchangeable" applies to the output flange and overall dimensions, not necessarily every input adapter plate configuration. Contact Korea Ever-Power with the specific competitor model number you are replacing; our team will confirm compatibility and any adapter plate differences for your motor before you place the order.

问What is the difference between EP-AB and EP-AF in the Korea Ever-Power inline range?

Both EP-AB and EP-AF are inline precision planetary gearboxes with the same backlash grades (P0/P1/P2) and efficiency (≥97% single-stage). The structural difference is the output shaft design: EP-AB uses a standard shaft diameter optimised for coupling and flange-mount applications. EP-AF uses a high-rigidity (enlarged diameter) output shaft specifically designed for applications where a gear, pulley, or cam is mounted directly on the shaft end — imposing radial and bending loads on the shaft. If your load connects to the gearbox via a coupling or rotary table flange, specify EP-AB. If you are mounting a gear or belt pulley directly on the output shaft without a separate bearing, specify EP-AF instead.
