TM 260.05 Experimental Module Block on Ring Friction Show data sheet (pdf file) Print page
Technical 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
