Planetary gearheads are high-precision, motion-control devices that generate substantial torque for their size, have high torsional stiffness, and low backlash — making them suitable for wide-ranging tasks.

Choosing the right gearhead and accurately sizing it is critical to long and reliable life. As a starting point, designers can approximate required gearhead size from:

Tr = Tm × r × e

where Tr = application torque, Tm = continuous torque, r = ratio, and e = efficiency.

To precisely size a gearhead, however, engineers must consider the complete motion profile, including speed, torque, acceleration, deceleration, and cycle rate. Our technical engineers can help you with specifying and supplying the right gear heads. Contact us
