TM 260.01 Rolling friction in friction wheels



  • Investigation of slip forces between two rotating discs in contact


Technical Description

The slip forces between two rotating friction discs in contact can be determined using this accessory module. The unit is intended for operation with the basic module TM 260. Connection to the basic module is made using a clamped coupling. The slip between the discs is maintained at a constant 4% by a gearbox. The contact pressure can be adjusted in steps (10N) up to max. 80N. This adjustment is performed using a lever with a mechanical advantage of 2:1. A strain gauge force transducer connected to the controller measures the friction forces directly. The unit has a container for supplying lubricant. Knurled bolts enable the friction discs to be changed easily.

Learning Objectives / Experiments
- Friction forces as a function of the load
- Friction forces as a function of the lubrication
- Friction forces as a function of the operating speed
