Abstract

The variable speed friction drive with an input shaft (1) in line with an output shaft (12) has a boss (2) with a rectangular hole (18) through it, mounted on a square section portion (17) of the input shaft. This allows it to oscillate on the shaft, assisted by a spring (19) inside the hole. The boss also carries two arms (22) each side, in scissor formation in pairs, each arm carrying a weight (23) at its end. A disc (3) is mounted on ball bearings (21) around the boss. This disc has sloping peripheral surfaces (30,31) acting as frictional driving surfaces. The outer surfaces (30) act against sloping surfaces (33) on the rims of two wheels (7,8) attached to the casing. The inner surfaces (31) act on surfaces (34) on two rims (10,11) of a cup shaped disc (9) attached to the output shaft. When the driving shaft turns, the rim (4) on the disc (3) oscillates slowly and drives the cup-shaped disc to give the required speed difference.
