Product Details
Product Overview
This unit is the worm gearmotor, with the motor mounted directly on the reducer. Sliding contact between worm and wheel gives high reduction in one stage, with self-locking behaviour at high ratios.
Structure and Key Features
- Gears in alloy steel, case hardened, ground and lapped in pairs.
- Split cast-iron housing with bores machined in one set-up.
- Taper or spherical roller bearings carry radial and axial loads.
Specifications and Selection
Confirm output speed, torque, service factor and mounting position; allow for lower efficiency than helical units.
Applications
Conveyors, mixers, door drives and light-duty machinery.
Frequently Asked Questions
Worm unit runs hot at low speed
Sliding friction generates heat at high ratio; check oil grade and ensure the duty cycle suits the thermal rating.
