Helical Gearboxes Handle Higher Torque with Less Noise

The new PE helical gearboxes from Stober Drives Inc., Maysville, Ky., handle more torque, generate less noise, and provide smoother motion than spur-gear units. The units come in four case sizes ranging from PE2 to PE5, and can have single or double stages with ratios from 3:1 to 100:1. Output torques range up to 310 Nm and inputs speed can be as high as 8,000 rpm. Backlash ratings are as low as 8 arc minutes.

The units can be ordered as in-line gear units with a motor adapter for third-party motors, a laremotor inut shaft option, or an integrated housing that mounts to the most popular motor dimensions. The gearboxes are said to have low friction levels and high shaft-load capacities, making them well suited for a variety of applications, including packaging and general automation.
