เกียร์ทดรอบแบบดาวเคราะห์ EP-AER ซีรีส์ มุมฉาก หน้าแปลนขนาดใหญ่

เดอะ EP-AER series right-angle large-flange planetary gearbox is the direct 90-degree version of the EP-AE inline large-flange series, adding a right-angle output direction change while preserving all three of EP-AE's defining characteristics: the oversized large flange whose outer diameter extends beyond the gearbox body for high overturning moment resistance, the IP67 upgrade option available on no other right-angle series in the precision range, and the fixed ≤8 arcmin single-stage backlash specification without P0/P1/P2 grade selection. Seven frame sizes from EP-AER050 to EP-AER235 cover 14 N·m to 2,000 N·m output torque with ≥97% single-stage efficiency and −10 °C to +90 °C operating range.

เดอะ EP-AERS compact variant extends the same large-flange right-angle IP67 specification to four smaller frames (050S–120S) covering up to 330 N·m, for applications requiring the same interface and environmental properties in smaller installed dimensions.

EP-AER — Full Frame Range

EP-AERS — Compact Variant

Food Processing Right-Angle Conveyor Heads — IP67

Korean food processing lines — poultry and seafood conveyor transfer heads, filling station drives, CIP-compatible accumulation conveyors — require right-angle drives where the motor is positioned perpendicular to the conveyor belt axis (motor inside a dry protected cabinet, output shaft through a sealed bulkhead into the wet conveyor zone). EP-AER with IP67 handles the continuous CIP washdown, steam-cleaning, and pooled water that occurs in these zones. The large flange carries the conveyor belt tension overturning moment at the transfer head without bolt-face fretting. AER090 and AER120 at ratios 20–50 cover the most common Korean food-line conveyor head torque ranges.

Outdoor Wastewater Treatment — Large Flange, IP67, Right-Angle

Korean wastewater treatment plant aeration and agitator systems use horizontal motors driving vertical agitator shafts — a 90-degree direction change through the tank wall. The right-angle drive unit sits at the tank top, exposed to splashing and accumulated water. EP-AER IP67 protects against the coastal spray and monsoon rain accumulation that exceeds IP65 protection in outdoor Korean treatment plant environments. The large flange carries the agitator shaft overturning moment from fluid resistance. AER120 and AER155 at ratios 25–50 cover most Korean wastewater agitator drive torque requirements. Pairs with self-locking worm reducers for additional speed reduction and gravity holding on power failure.

Heavy Rotary Table Side Drive — Large Flange Right-Angle

Korean heavy industrial rotary tables — steel billet handling, large fixture rotation, welding turntable systems — where the table drive motor cannot be positioned below or behind the table (floor-mounted with motor inside the base, output shaft driving the table from the side) use a right-angle drive. The large flange of EP-AER carries the combined overturning moment from the table workpiece weight and the motor-gearbox assembly cantilever, without the bolt-face micro-fretting that occurs at a standard flange under these combined loads. AER155 and AER205 at ratios 20–50 cover the torque range for Korean heavy industrial side-entry table drives.

Pharmaceutical Clean Room — IP67 Right-Angle Drives

Korean pharmaceutical equipment requiring right-angle drives in process zones subject to spray cleaning, deionised water rinsing, and occasional submersion-level cleaning specifies IP67 for the drive unit. EP-AER with IP67 documents the required protection level for GMP machine qualification audits in Korean pharmaceutical manufacturing facilities. The large flange's structural interface supports the moment loads from mixing paddles, bottle transfer arms, and conveyor heads in a single sealed, IP67-certified housing. AER070 and AER090 at ratios 15–35 cover most Korean pharmaceutical process drive torque requirements.

Agricultural Machinery Right-Angle Drives — AERS Compact

Korean precision agriculture seeder and spreader mechanisms where the drive shaft must turn a corner to reach a working head mounted at 90 degrees to the drive motor axis use EP-AERS (050S–120S, up to 330 N·m) for compact right-angle large-flange installations. The IP65 standard sealing is suitable for outdoor agricultural exposure; IP67 can be specified for equipment installed in flood-prone field conditions or subject to regular pressure washing. Downstream agricultural bevel gearboxes distribute the AERS output to multiple seeder heads from a single right-angle drive unit.

Marine and Port Equipment — IP67 Large Flange

Korean port and marine equipment — dock leveller actuators, mooring equipment, shipyard positioning fixtures — combines outdoor coastal spray exposure, occasional standing water, and large moment loads at the drive output. EP-AER IP67 at AER205 and AER235 delivers the large-flange structural capacity for heavy port loads with the full-submersion protection required for equipment installed at tidal height where temporary immersion at dockside is possible. The right-angle output allows the motor to be positioned in a protected dry housing while the gearbox output shaft faces the exposed marine environment. Pairs with CV joint drive shafts for offset load connections in port equipment installations.

🇰🇷

EP-AER090 IP67, i=25 for the conveyor head right-angle drive on our fish processing line. Motor inside a dry SS cabinet, output shaft through an IP67-gasketed bulkhead plate into the wet processing zone. Previous arrangement used EP-ABR with an additional IP67 shaft seal retrofit — the retrofit was never fully reliable and failed twice during our six-month HACCP audit cycle. EP-AER factory-specified IP67 resolved this completely. 19 months, twice-daily CIP with NaOH and peracetic acid, zero IP events. The large flange carries the conveyor head belt tension moment — no bolt retightening in 19 months. Korea Ever-Power provided the IP67 test certificate in Korean for our auditor within three working days.

EP-AER155 IP67, i=35 for outdoor aeration agitator drives at a coastal wastewater treatment plant — right-angle from horizontal motor to vertical agitator shaft, mounted at tank top. After three summer typhoon seasons and three jangma periods, zero water ingress incidents. Previous IP65 drives had two ingress failures per season from tide surge. The large flange handles the agitator shaft side-load at 1.4 m blade diameter; we specifically chose AER over ABR for the flange size after the previous standard-flange drive showed micro-fretting at 18 months. 30 months, 12 units, no ingress, no flange issues.

EP-AERS090S IP67, i=20 for a right-angle conveyor drive in a GMP oral solid dosage room. Required IP67 for GMP documentation, right-angle output to fit within the machine profile, and large flange for mounting torque reaction. The AERS compact variant fit the machine space where a full AER090 was too long. Korea Ever-Power produced the IP67 test report and material declaration in the format required by our FSSC 22000 auditor — first time any gearbox supplier has cleared our GMP qualification round in a single documentation cycle without clarification requests. 16 months production, zero drive-related quality events.

CV Joint Drive Shafts

For EP-AER port and marine installations where the right-angle output shaft must reach an offset load — dock equipment, shipyard positioners — and for dual-drive large industrial rotary table configurations where two EP-AER units drive a table from opposite sides, heavy-duty CV joint drive shafts transmit the output torque through offset and misalignment in wet and outdoor conditions.

Worm Gear Reducers

For vertical EP-AER right-angle output axes carrying gravity loads — outdoor agitator shafts, vertical column positioners, hoist mechanisms in wet environments — self-locking worm gear reducers in sealed housings hold the vertical load on power failure without electromagnetic brakes. Worm stages extend the EP-AER ratio range below i=100 for ultra-slow positioning in outdoor and washdown installations.

Agricultural Gearboxes

For Korean precision agriculture right-angle drive systems where EP-AERS provides the compact right-angle large-flange stage and downstream agricultural bevel gearboxes distribute power to multiple seeder or spreader heads — IP65 standard or IP67 optional depending on field exposure conditions — Korea Ever-Power's agricultural bevel gearboxes complete the outdoor drive train from EP-AERS output to working element.

คิวCan I get EP-AER with P0 ≤1 arcmin for a precision servo axis?

No. EP-AER does not offer P0/P1/P2 grade selection — the backlash specification is fixed at ≤8 arcmin single-stage and ≤12 arcmin two-stage for all frames. This is the same as the EP-AE inline series: the large-flange series carries a fixed backlash specification. If ≤5 arcmin or tighter is required with a right-angle output, use EP-ABR (square flange, P0 ≤1 arcmin) or EP-ADR (round flange, P0 ≤1 arcmin). Neither of those series offers IP67, so if IP67 is also required at ≤5 arcmin or tighter, there is no Korea Ever-Power right-angle product that satisfies all three — contact Korea Ever-Power for project-specific options.

คิวWhy does EP-AER two-stage start at i=15 rather than i=12?

The EP-AER two-stage ratio range begins at i=15 — consistent with the EP-AE inline series, which also starts at i=15. The large-flange gear train configuration does not include an i=12 two-stage combination. If i=12 with a right-angle output is required, the only available Korea Ever-Power right-angle product that includes i=12 is EP-ABR (square flange). There is no right-angle large-flange series with i=12 available in the standard catalogue range.

คิวIs IP67 on EP-AER factory-built or can it be retrofitted to an existing IP65 unit?

IP67 is a factory-built specification only — it cannot be retrofitted to an IP65 EP-AER unit in the field. The IP67 sealing geometry, seal materials, and closure interfaces differ from the IP65 unit at multiple points in the assembly that cannot be changed after manufacture. If your installation environment has changed and you now require IP67, a replacement with a factory-built IP67 unit is required. Always specify IP67 at the time of ordering to avoid a separate replacement purchase.

คิวAre EP-AER and EP-AE output flanges the same dimensions at the same frame number?

The output flange outer diameter, pilot diameter, and bolt-circle of EP-AER match EP-AE at the same frame number — the large-flange geometry is consistent between the inline and right-angle variants of the AE family. The output-side machine interface can use the same drawings for the flange mounting pocket in both cases. However, the overall gearbox body dimensions and the motor input axis orientation are completely different between inline and right-angle versions. Always verify the EP-AER dimensional drawing for the full gearbox envelope before finalising the machine design.

คิวIs there a BMEMB-series equivalent to EP-AER?

เดอะ EP-BAE large flange planetary gearbox is the BMEMB-series large-flange product — however, it is an inline series (non-right-angle). There is no BMEMB-series right-angle large-flange equivalent to EP-AER in the current Korea Ever-Power catalogue. For right-angle large-flange right-angle applications, EP-AER is the sole option in the Korea Ever-Power range regardless of whether Apex Dynamics or BMEMB series precision is the primary specification.
