Helical gearbox

The SPH Series in-line planetary gearbox, with helical gearing, is designed specifically for dynamic and cyclic motioncontrol applications, as well as high-speed and continuous-duty applications. The gears are cut at an angle to reduce axial forces that are traditionally associated with helical gearing and then ground to reduce noise and improve smoothness and accuracy. Wider gear teeth allow for larger permissible torques relative to the frame size and heavy-duty taper roller bearings permit large loading capabilities.

Six frame sizes are available — from 50 to 180 mm — with ratios up to 100:1. The SPH comes with several output configurations for simple machine integration including shaft (smooth or keyed), hollow with housing, and integrated coupling.
