Experimental Module Block on Ring Friction- Engineering Lab Training Systems.
Technical Description
Using this instructional unit,
investigations are performed on wear. The unit is intended for operation
with the basic module . A dog coupling transmits the force from the
drive unit. For the experiments, pins made of various materials rub
against the external surface of a rotating disc under varying
lubrication conditions. Initially a point contact is formed, as the wear
increases, this changes to a surface contact. The friction wheel is
made of hardened stainless steel, the surface is ground. There is a
container for lubricant underneath the friction wheel. The pins are
loaded using a lever with weights. The friction forces are measured with
the aid of a full bridge strain gauge on the lever joint.
