FF-1121 Bearing Friction Apparatus

Experiments

  • Determination of friction torque on sliding bearings: various material pairings by means of interchangeable bearing shells.
  • Determination of the friction torque on a rolling bearing.
  • Comparison between sliding and rolling bearing.
  • Fundamental experiments in rotational dynamics.

Description

This apparatus is designed to demonstrate the categorical difference between sliding and rolling friction and its application for different industrial uses. Apparatus uses different types of plain and rolling bearing of different materials like iron and bronze.

Apparatus includes flywheel mounted upon an axle. Axle is supported in a plain or ball bearing and bearing housing is attached with wall bracket. Torque is applied by putting dead weights on the flywheel using hanger which corresponds to the frictional torque when motion begins.
