Helical Gearbox

GAM Gear (Mt. Prospect, IL) has introduced the SPH series inline planetary gearbox featuring helical gearing. It is designed for dynamic and cyclic motion control applications, and can be optimized for high-speed and continuous-duty applications. The gears are cut at an angle to help reduce axial forces associated with helical gearing, and then are ground for reduced noise levels and improved smoothness. The gear teeth are wider, allowing for larger permissible torques relative to the frame size, and heavy-duty taper roller bearings enable large loading capabilities.

Available in six frame sizes from 50 mm to 180 mm, and with ratios up to 100:1, the gearbox offers several output configurations for machine integration, including shaft (smooth or keyed), hollow with housing, and integrated coupling.
