Application

Overrunning

An application to alternately repeat the conditions where the inner and outer races of the cam clutch engage to transmit the torque and where they continue spinning around depending on the difference in the rotation speed or rotation direction. The operation is the same as the free wheeling of a car.

Applications

Layout

Each cam clutch is equipped with a sprocket (transmission element) and mounted on a roller shaft.
Cam clutches are mostly used in conveyor roller tables for plate glass, plaster boards, and other plate-like materials.

Purpose of Use and Operation Overview

During Normal Operation

Each cam clutch is mounted with a sprocket and built into a roller shaft. The roller rotates when the cam clutches engage.
Engagement: A state in which the outer race, cam, and inner race integrate and transmit power from the drive side to the driven element. In this example, the torque is transmitted from the outer race to the inner race via the engagement of the cam clutches.

During a Power Outage

Objects are conveyed by pushing them by hand. At this time, the cam clutches overrun, which enables the objects to be damage-free and conveyed without slipping on the roller.
Overrunning: A state in which the inner race can rotate in the direction of the red arrow while the outer race is stopped.

Advantage of using the cam clutch

  • ・The overrunning function enables heavy objects to be conveyed without damage.
