What are the common types of reducers? How to choose?

Common types:

Gear reducers (such as planetary gears, parallel shaft gears): high efficiency (90%~98%), suitable for heavy loads.

Worm reducer: compact structure, self-locking, but low efficiency (60%~70%).

Cycloidal reducer: high reduction ratio, impact resistance, used in chemical industry, mining.

Harmonic reducer: high precision, used in robots, aerospace.

Selection points:

Load type: select gear reducer for constant load, select cycloid reducer for frequent start and stop or impact load.

Reduction ratio: calculated according to output speed requirements (reduction ratio = input speed/output speed).

Installation space: planetary reducer is small and suitable for compact space.

Precision requirements: select harmonic or servo-specific reducer for high precision occasions.
