DH1618 Unhardened Steel WormWhen used with worm gears, Boston Gear worms provide an effective answer for power transmission applications requiring high ratio speed reduction in a limited space using right angle (90), non intersecting shafts. Manufactured from acetal, nylon, and hardened and unhardened steel, they offer the smoothest, quietest form of gearing when properly applied. Because the efficiency of a worm gear drive depends on the lead angle and number of starts on the

Friction discs rotate with the motor shaft and are free to move axially on the hub

mounting on inclined conveyors for frame clearance

Traditional cost effective rigid coupling design provides torque transmission and alignment

Boston Gear’s internal gears are spur gears turned "inside out

Collars include stainless steel screws

bar lengths (up to 105")

Effective on both hard and soft shafts

glass-filled bearings are self-lubricating and offer a low coefficient of friction

Riser blocks permit the speed reducer to be mounted in the most desirable
