A sectioned industrial, mounted cycloidal gear reducer for use in classroom and laboratory training relating to mechanical drives. This example, procured as industrial surplus, has been restored, cut away and refinished using durable coatings.

Sharing many design features with planetary gear reducers, including their straight-through design, these commonly-encountered epicyclical reducers, are often chosen for high-torque servo motor applications due to their low/no backlash, low wear, high-shock load, and high-torque operating characteristics. A full 90 degree cutaway unveils primary components including the cycloidal disk, pins/rollers, and ring gear. Motion is retained and reversing shaft rotation can be demonstrated.

The device is mounted on a modular, heavy-gauge steel baseplate. For industrial relevancy, common models, by well-known manufacturers are chosen. All examples can be mounted on related DAC bench, workstation and storage products. All operational features have been retained allowing the reducer to be operated via hand crank, and replacement hardware has been provided where necessary.
7-Gauge, formed-steel, powder-coated baseplate with provision for bench-top, workstation and storage rack mounting.
