DESCRIPTION

The Pin on Disc Friction & Wear Test Rig is intended for determination of tribological
properties of different materials.
(i)
Ascertain the validity of law’s of friction
(ii) Wear characteristics of the given specimen
(iii) Determination of wear constant
(iv) Understand the effect of parameters

This is a study versatile machine, which facilitates study of friction and wear
characteristics in sliding contacts under desired conditions. Sliding occurs between the
stationary pin and a rotation disc. Normal load, rotational speed and wear track diameter
can be varying to suit the test conditions. Frictional force and wear (displacement) are
monitored through electronic sensors and recorded to PC.

The major parts of the wear and friction monitor are mechanical assembly, Base plate,
Guide Base, AC Motor, AC Drive and spindle assembly, loading arrangement with 1:1
leverage ratio with a pulley, loading pan with dead weights, wear disc holder, scale to set
the track radius, LVDT for displacement, and load cell for frictional force.
