Belt Friction Unit

The Belt Friction Unit  allows us to carry out studies and investigations to compare the driving torque for a given degree of overlap of a flat belt (leather or rope) and a `V´ belt. We can observe the relationship between the tensions in the two sides of a belt, to evaluate the differences between flat (leather or rope) and “V” belts and to investigate the effect of the angle lap, among others.

The unit is mounted in a metallic structure and basically consists of a pulley, 3 belts and load hangers.

4 pulleys: a flat one and 3 "V" pulleys (one of them is correctly fitted and the others are badly fitted). The angle of overlap can be varied in

increments of 10 degrees.

The pulley is balanced and mounted on bearings to reduce frictional losses. It has machined grooves to suit the belts.

Three belts are supplied (“V”, leather and rope).

Set of weights.

Manuals:   This unit is supplied with the following manuals: Required services, Assembly and Installation, Starting-up, Security, Maintenance and Practices manual.

Dimensions: 550 x 500 x 600 mm. approx. (21.65  x 19.68  x 23.62 inches approx.).    

Weight: 15 Kg. approx. (33 pounds approx.).

1- Investigation of the relationship between the belt tensions and the angle of lap for a flat belt.

2- Comparison of the driving torque for a giving angle of lap.

Other possible practices:

3- To evaluate the differences between Vee `V´and flat belts.

4- To determine the coefficient of friction between the pulley and belt for the belt sections.

5- To verify the belt tension equation.
