Spur Gear Drive for DC Motors

Applications

Instrumentation, diamond machinery, peristaltic pumps, motorized displays, programming devices, cam timers, medical equipment, valves, and actuators.

Description

GBB is a spur gear drive designed for DC motors with diameters up to 33 mm. It offers 0.5Nm gear torque and gear ratios from 4.66 to 1953. This 33mm OD off-center shaft gearhead features 2 to 8-stage reduction, with polyacetal gears in the initial stages and steel sintered gears in the final stages. It has a nominal torque rating of 0.5Nm and a peak torque of up to 0.8Nm.

The GBB comes in three housing sizes based on gear reduction stages. Ideal for motorized displays and programming devices, it supports mounting 2 series of synchronous motors and PM stepper motors, with the option for 3 series motors on request.
