Abstract

A clutch is shown consisting of driven plate 1 and driving plate 2 in Fig. 1. Driving plate 2 has two driving pins 3 and 4 mounted on it. Driving pin 3 is longer than driving pin 4. The driven plate 1 has a series of countersunk holes 5 for receiving driving pins 3 and 4 from driving plate 2. The arrangement of the countersunk holes 5 in driven plate 1 is shown in Fig. 2. It should be noted that there is a sharp edge connecting the countersunk holes 5 in driven plate 1.

Drive Clutch

A clutch is shown consisting of driven plate 1 and driving plate 2 in Fig. 1. Driving plate 2 has two driving pins 3 and 4 mounted on it. Driving pin 3 is longer than driving pin 4. The driven plate 1 has a series of countersunk holes 5 for receiving driving pins 3 and 4 from driving plate 2. The arrangement of the countersunk holes 5 in driven plate 1 is shown in Fig. 2. It should be noted that there is a sharp edge connecting the countersunk holes 5 in driven plate 1.

The purpose of having driving pin 3 longer than driving pin 4 on driving plate 2 is such that driving pin 3 will engage driven plate 1 ahead of driving plate 4, causing driven plate 1 to align itself with driving pin 3 and allowing driving pin 4 to enter into its corresponding countersunk hole in driven plate 1. This arrangement assures that driving plate 2 will engage driven plate 1 whenever driving plate 2 is moved into engagement with driven plate 1.

Driving plate 2 is then rotated which, in turn, causes driven plate 1 to rotate. Motion is transmitted to driven plate 1 through the driving pins 3 and 4 to the side walls of the countersunk holes 5 in driven plate 1. Under these conditions, no upward force is exerted on driven plate 1 by driving plate 2.

Driving plate 2 may be disengaged by lowering driving plate 2 from engagement with driven plate 1, while both the driving plate 2 and the driven plate 1 are in motion.
