Worm Gear Speed Reducers

Worm Gear Speed Reducers


Ch and 2Ch (Ч и 2Ч) worm gear speed reducers offers high ratio reduction with few moving parts in a close-coupled compact drive. The right angle arrangement of driving-to-driven machine requires a minimum of space. Efficient motor speeds are reduced to slow speed requirements of many industrial machines in one reduction.
