This unit has been designed to perform studies and experiments on surface friction and the function of a plate clutch.
We can also carry out experiments to investigate the relationship between the pressure applied to the friction surfaces, the radius of the friction discs and the torque.
This unit is mounted on an aluminium and painted steel structure.
The unit comprises a lower plate and a upper plate. On top of the lower plate sits the upper plate whose shaft rotates in ball bearings.
Between the lower and upper plates will be the interchangeable friction discs. Three interchangeable discs of different diameters are supplied.
The self weight of the upper plate is the minimum pressure or force on the friction disc. Adding weights to the upper plate we can increase the contact pressure.
Torque is applied to the upper plate through pulleys and loaded cords. By means of hangers and masses or weights we can modify the loading force and also adjust the torque.
In order to carry out some of the practices with MEM unit, 2 set of weights “B type” are required.
This unit can be wall mounted.
This unit is supplied with the following manuals: Required services, Assembly and Installation, Starting-up, Security, Maintenance and Practices manual.
Dimensions: 400 x 300 x 400 mm. approx. (15.75 x 11.81 x 15.75 inches approx.). Weight: 15 Kg. approx. (33 pounds approx.).
1- Function of a plate clutch.
2- Relationship between contact force and friction moment.
3- To determine the coefficient of friction.
4- To study the influence of the materials used on the friction moment.
5- To study the influence of the friction surface geometry on the friction moment.
6- To investigate the relationship between the pressure applied to the friction surfaces, the radius of the friction surfaces, the number of friction surfaces and the torque.
7- To show that the minimum torque to maintain rotation is proportional to the axial load and diameter of the friction surface.
