เกียร์ทดรอบแบบอินไลน์แพลเนตารีหน้าแปลนขนาดใหญ่ รุ่น EP-AE

The EP-AE series large-flange planetary gearbox combines two structural advantages in one product: an oversized output flange whose outer diameter extends beyond the gearbox body to resist overturning moments at the machine interface, and the option to upgrade to IP67 water-submersion protection — a combination available nowhere else in the Korea Ever-Power inline planetary range. Seven frame sizes from EP-AE050 to EP-AE235 cover 14 N·m to 2,000 N·m with ≥97% single-stage efficiency and a −10 °C to +90 °C operating range.

The backlash specification is ≤8 arcmin single-stage และ ≤12 arcmin two-stage — a fixed value with no P0/P1/P2 grade selection. This positions EP-AE as the choice for applications where sub-5-arcminute positioning precision is not the primary specification, but where the flange interface must carry significant structural load, the environment is wet or wash-prone, and the ≥97% efficiency and −10 to +90 °C range of the precision family are still required. A compact EP-AES variant extends the same specification to four smaller frames (050S–120S) covering up to 330 N·m for lighter-duty large-flange applications.

When IP65 is Not Enough — and EP-AE IP67 Solves It

When a cantilevered load — a heavy rotary table workpiece, a robot arm, or a spindle head — applies a force perpendicular to the output shaft axis, it creates a bending couple at the large flange planetary gearbox output interface. The mounting bolts on the tension side must resist this overturning moment; their effectiveness scales linearly with the bolt-circle radius. EP-AE's oversized flange extends this radius well beyond the gearbox body diameter, dramatically increasing the structural capacity of the mounting interface without any change to the gear train.

🇰🇷

EP-AE090 IP67 at 25:1 for poultry processing conveyor drives. We had three water ingress failures with IP65-only units in the first year of operation — the HACCP foam-and-rinse cycle was causing sustained water accumulation at the gearbox base that exceeded IP65 protection. The EP-AE with IP67 has now run 22 months through twice-daily foam-and-rinse cycles without a single ingress incident. The large flange carries the conveyor belt tension loads without the micro-fretting at the mounting face we had with a standard-flange unit. Zero food contamination incidents from drive lubrication in the whole period.

EP-AE205 at 40:1 for a heavy rotary table in our steel billet handling line. The table carries 2,500 kg billets at 600 mm overhang radius — the overturning moment at the drive flange is substantial. Previously with a standard-flange drive of equivalent torque, the flange interface developed micro-fretting after 6 months and we had to retighten bolts quarterly. The EP-AE205 large flange has now run 18 months with zero bolt-retightening intervention. The ≤8 arcmin backlash is more than adequate for billet positioning — we don't need servo-precision for this application, and we paid the right price for the right spec.

EP-AE120 IP67 at 35:1 for outdoor aeration equipment drives at a coastal treatment plant. The monsoon season and coastal spray environment had caused two drive failures per year with IP65 units — salt spray combined with accumulated water during typhoon-level events. EP-AE with IP67 has now run through three monsoon seasons without a single ingress-related failure. The −10 °C lower limit also covers our January coastal winter temperatures where the previous units needed heated startup enclosures. Maintenance team is very happy — no quarterly seal inspections required.

EP-AES090S IP67 at 20:1 for a filling machine conveyor in a beverage clean room. The AES allowed us to use the large-flange geometry on a smaller drive where a full AE090 was physically too large for the conveyor head mounting space. IP67 is required in our FSSC 22000 specification for this line. Korea Ever-Power supplied the IP67 test certificate in the format our auditor required — first time a gearbox supplier has provided documentation that passed our qualification auditor without any back-and-forth requests for clarification. 16 months, clean room production, zero quality events from the drive units.

CV Joint Drive Shafts

In food processing, pharmaceutical, and wet-environment machine installations where the EP-AE drives a conveyor or mechanism at an offset position from the gearbox centre, precision CV joint drive shafts transmit the output torque through the offset without introducing additional backlash or misalignment loads. IP-rated drive shaft configurations suit the same washdown environments as EP-AE IP67.

Worm Gear Reducers

For outdoor lifting equipment, wastewater treatment vertical agitators, and food-line vertical elevation drives using EP-AE, a downstream self-locking worm gear reducer holds the vertical load on power interruption without a brake. Worm reducers in sealed housing also suit the same wet, outdoor, and washdown environments as EP-AE IP67 — maintaining the sealed drive train from motor through to the final output.

Agricultural Gearboxes

Korean outdoor agricultural automation — precision irrigation system drives, seeder head actuators, and harvester platform positioning — operates in exactly the wet, wide-temperature-range conditions that EP-AE IP67 addresses. Downstream bevel and spiral-bevel agricultural gearboxes from Korea Ever-Power connect to EP-AE output shafts for multi-output PTO configurations in precision farming equipment.

คิวCan I upgrade my existing EP-AE from IP65 to IP67 in the field?

No. IP67 sealing is built into the unit at manufacture — it requires specific seal geometries, seal materials, and closure interfaces that differ from the IP65 unit at multiple points in the assembly. Field modification of an IP65 unit to IP67 standard is not possible and cannot be certified. If your installation environment has changed and you now require IP67, the unit must be replaced with a factory-built IP67 specification. Korea Ever-Power can assist with expedited replacement orders where an existing IP65 installation must be upgraded. Always specify your IP requirement at the time of ordering.

คิวThe EP-AE backlash is ≤8 arcmin — is this the same as the P2 grade in the EP-AB series?

Numerically, yes — EP-AB P2 single-stage is ≤5 arcmin, not ≤8 arcmin. The EP-AE ≤8 arcmin is actually equivalent to the EP-AB P2 two-stage specification (also ≤7 arcmin) or slightly looser. The practical distinction is that EP-AE is a single-precision-level product with no grade options, while EP-AB offers P0/P1/P2. EP-AE is not a "P2-grade AB with a bigger flange" — it is an independent product line where the large flange, IP67 option, and larger maximum frame size (AE235 vs AB220) are the primary selection drivers, and ≤8 arcmin is the precision specification that serves these application categories.

คิวWhy does EP-AE two-stage start at i=15, not i=12 like EP-AB?

The EP-AE gear train geometry is optimised for the large-flange configuration and the product's precision and structural requirements — this results in a two-stage ratio range starting at i=15 rather than i=12. If your application requires i=12 two-stage, use EP-AB (which includes i=12 and i=16). If i=15 is acceptable, EP-AE covers it. For single-stage applications at i=3 through i=10, both series provide the same complete ratio set.

คิวHow do I choose between EP-AE050 (full size) and EP-AES050S (compact)? The model numbers look the same.

The "S" suffix differentiates the AES compact variant from the AE full-size series. EP-AE050 is the smallest frame of the full EP-AE range; EP-AES050S is the smallest frame of the EP-AES compact range. While both have 50 mm body diameters, the AES compact variant has smaller overall dimensions and a lower maximum torque. Korea Ever-Power supplies dimensional drawings for both upon request — compare the output shaft diameter, flange bolt-circle, and overall length before selecting. If the torque requirement is within 330 N·m and machine space is constrained, AES is likely the correct choice. Above 330 N·m, use the full EP-AE series.

คิวDoes IP67 affect the operating temperature range or lubrication specification of EP-AE?

The operating temperature range (−10 °C to +90 °C) and lubrication specification are the same for both IP65 and IP67 variants of EP-AE. The IP67 upgrade affects the sealing geometry and seal material at the shaft exits and housing joints — not the internal gear train, lubrication volume, or grease specification. However, for IP67 units that may be regularly submerged or operate in environments where the external temperature cycles widely, Korea Ever-Power recommends confirming the seal integrity at periodic inspection intervals — not because the sealed-for-life specification changes, but because external physical damage to seal lips (from abrasion, chemical exposure, or mechanical contact) is best detected early in wet environments.
