Rear Wheel Axle Assembly

Description

A series of models to demonstrate different gearing systems. With transparent slideplates, the gears may easily be seen and where necessary there is an index on the primary and secondary shafts to show the change in the direction of rotation and the relative speed of rotation. A simple three-speed and reverse-gear system using spur gears. Reverse gear is obtained by interposing a small lay-shaft mounted pinion between the two main shafts. Gear selection is by means of a short ball-ended lever.

Description

For use as a water turbine to drive a generator producing electricity or for use as a pump driven by a motor and raising a head of water to produce potential energy. The rotor has eight 'bucket' blades and is housed in a block turbine chamber with a clear Perspex front. Two inlet tubules (for turbine and pump operation respectively) and one outlet tubule are provided and the shaft carries a 15 mm. diameter pulley. With driving belt.
