Right Angle Worm Gear Reducers

Right-angle worm gear reducers deliver 90-degree power transmission in a compact, quiet, mechanically simple package.

Winsmith RD Series right-angle worm gear reducer

Overview

Right-angle worm gear reducers deliver 90-degree power transmission in a compact, quiet, mechanically simple package. The worm-and-wheel geometry is naturally self-locking at high reduction ratios, which makes these units the default choice for hoists, winches, lifting gear, and indexing tables that need to hold a load without an external brake. They also fit cleanly into tight machine envelopes: packaging lines, conveyors, mixers, and process equipment, where a parallel-shaft footprint would not.

Frequently Asked Questions

Why pick a worm gear reducer instead of a helical-bevel right-angle unit?
Worm reducers are simple, compact, quiet, and inherently self-locking at high ratios, useful for hoists and holding loads. Helical-bevel units are more efficient under continuous duty. We help size for your duty cycle.
Are worm reducers cross-compatible across Boston Gear, Winsmith, and Cone Drive?
Often the input/output dimensions match closely on common frame sizes. We cross-reference center distance, ratio, output torque, and shaft dimensions before quoting a replacement.
