Aluminum-body gear reducer uses worm wheels and shafts

A speed reducer built by the Italian firm Varvel is now available through DieQua Corp., Bloomingdale, Ill. It features a square aluminum body and uses worm wheels and worm shafts to provide input/output ratios from 5:1 to 100:1 in a single stage. For higher ratios, input modules with helical or worm gears can be added to make two-stage devices. Sizes range from 28-mm center distances to 110-mm center distances. For larger sizes, customers can special order Varvel’s round-body reducers with up to 150-mm center distances. Torque capacities range from 159 to 6,115 lb-in. (based on a 1,750-rpm input speed). Output and input shafts can be inch or metric, and input adapters for NEMA and IEC standard motors are available.
