Drive coupling for fruit machine reels

摘要

A range of different items of rotational elements, e.g. discs, drums, are coupled to the spindle (17) of an electric motor (3). The coupling (4) has a cylindrical end section (13) that fits into the bore (22) of the driven element. Formed radial keys (15) engage slots in the element to provide rotational coupling. The end of the coupling has a hexagonal recess (8) that engages a hexagonal disc (18) that is rigidly fixed to the spindle of the motor.
