Prony Brake Module, Imperial

8913

Description

The Prony Brake is a braking device based on pure mechanical friction. The friction is developed by a specially designed cast iron self-cooling friction pulley to be mounted on the shaft of the drive motor, and a friction belt slipped on the friction pulley. The friction belt is attached to a spring-scale mechanism in the Prony Brake module.

Loading is achieved by increasing the friction belt tension, which is controlled by a knurled wheel located on the faceplate. The torque developed is indicated on a circular scale that is graduated in Imperial units (lbf⋅in). An important and interesting feature of the Prony Brake is that the load torque is practically constant with speed for any load setting.

A metric version is also available. See Model 8913-10.
