TM 260 Tribology Trainer Basic Module Show data sheet (pdf file) Print page
Technical Description
The trainer enables different sliding and rolling friction cases to be investigated. The parameters of a tribological system can be assessed during this process. The drive module is the basis for experiments with a range of accessories. The unit consists of a sturdy frame made of anodised aluminium section. Rubber feet ensure that the table unit does not slip. The individual accessory modules are driven using a DC drive motor. The motor is connected to the controller. The rotational speed can be continuously and finely adjusted using a 10-turn potentiometer. The speed is regulated electronically and displayed digitally. Friction forces are measured using strain gauge transducers. The controller processes this data and displays it digitally. Snap-action fasteners for fixing the accessory modules to the frame simplify the rapid assembly and disassembly of the experiments.  
Learning Objectives / Experiments

The following experiments can be performed with the basic module when fitted with the appropriate accessory:
- Combined rolling and sliding friction of two discs

  with slip
- Elastohydrodynamic behaviour, EHD, rolling friction

  of a spherical object against a flat surface
- Abrasion testing: pin against a disc
- Abrasion testing: abrasive disc experiment
- Friction vibration and "stick-slip" effects
- Distribution of pressure in plain bearings
Features

* Drive module for investigating various sliding and

  rolling friction cases1
* Electronic measurement of the contact pressure

  between the friction materials using strain gauges1
* Modular overall concept
