MRYE2 Wheel and Differential Axle Unit

The Wheel and Differential Axle Unit, "MRYE2", has been designed by EDIBON to investigate the mechanics of a wheel and differential axle mechanism and demonstrating the force reduction on a differential pulley block.

A wheel, consisting of a pulley with a major diameter than the differential axle assembly consisting of a pulley of diameter 111 mm (larger axle) and a pulley of diameter 33 mm (smaller axle). The wheel and differential axle is secured to a shaft supported on ball bearings. Cords and weight holders are provided.

The wheel and the differential axle are fixed together to form a differential pulley block. The forces act, on one hand, directly on the peripheral of the pulley of the wheel and, on the other hand, through a loose pulley on two pulleys of differential axle. Easy to exchange weights permit the load to be varied so that equilibrium is obtained.

A single cord is attached to the wheel and wrapped around a number of times before leaving it hanging vertically. A weight holder is added to the end.

A second cord is attached between the larger and smaller axles of the differential axle. A weight holder and a loose pulley are hanged from the cord of the differential axle, which allows for a vertical suspension while the axle rotates.
