SEW KA47/T Gear Reducer Unit

Module Feature

KA47/T is SEW KA series right‑angle helical‑bevel gear reducer. The suffix /T means equipped with torque‑arm mounting. Compact housing, high transmission efficiency, hollow output shaft structure. It can assemble with SEW DRN series motors, widely used for conveyors and material‑handling equipmentAlibaba.

Working principle

Input high‑speed rotation transfers to helical‑bevel gear sets. Gear meshing reduces speed and amplifies output torque, changes power output direction by 90‑degree right‑angle transmission. Torque arm absorbs reaction torque during operation.

Onboard components

Helical‑bevel gear set, bearing assembly, cast gear housing, hollow output shaft, torque‑arm bracket, oil seal and sealing gaskets.

LED indicators

No onboard LED indicators. Condition judged by noise, vibration and oil temperature.

Hardware self‑diagnosis

Check gear‑oil level and leakage, monitor abnormal noise and vibration, inspect torque‑arm mounting tightness, check housing overheating.

Programming software

No configuration software, purely mechanical transmission component.
