MEMT-2 Dynamic Friction of a Cylinder on a Roller

This unit allows to demonstrate the friction forces between several cylinders of different materials and a roller under different lubrication conditions.

The "MEMT-2" unit consists of two levers that transmit a force applied by weights to a test pin to put it in contact with a disc coupled to a motor shaft that allow to demonstrate the friction forces between several friction test pins of different materials and the disc coupled to the motor shaft under different lubrication conditions.

Each test pin is made of different material and rubs against the external surface of a rotating steel disc coupled to the motor shaft under different lubrication conditions. There is a lubricant tank underneath the rotating disc.

Initially, a point contact is formed, as the wear increases it changes to a surface contact.

The speed of the rotating steel disc can be adjusted, and the test pins are loaded using two levers and a set of weights. A force sensor measures the friction forces as a function of the pairs of friction materials, the speed of the rotating disc, the load and the lubrication conditions.
