description

Using this instructional unit, investigations are performed on wear. The unit is intended for operation with the basic module TM 260. 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.

 

Learning Objectives / Experiments

- Friction force as function of the pairs of friction materials
- Friction force as a function of the relative speed of the components
- Friction force as a function of the lubrication conditions
- Wear as a function of the friction parameters
