Descrição Geral

This unit allows to study the friction forces between several vertical friction pins of different materials and a rotating friction disc.

The end of each vertical pin is made of a different material and rubs against the rotating steel disc. The speed of the rotating disc can be adjusted. The contact pressure between the vertical pin and the rotating disc can be adjusted with a lever and a set of weights. The disc is enclosed in an open vessel that can be filled with different lubricants. A force sensor measures the friction forces as function of the pairs of friction materials, the speed of the rotating disc, the load and the lubrication conditions.
