Prony Brake Module, Metric

8913-1

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 Metric units (N⋅m). An important and interesting feature of the Prony Brake is that the load torque is practically constant with speed for any load setting.

An imperial version is also available. See Model 8911-0.
