Abstract

A flexible. resilient and easily disengaged coupling is described which allows shaft installation and removal without axial movement of the shaft hubs. and which provides a flexible alignment and shock absorbing system. Such a coupling has use in electrophotographic copying machines where it is desirable that machine components be easily installed or readily removed from the machine housing.

"0" RING FLEXIBLE COUPLING (Cont d)

A flexible. resilient and easily disengaged coupling is described which allows shaft installation and removal without axial movement of the shaft hubs. and which provides a flexible alignment and shock absorbing system. Such a coupling has use in electrophotographic copying machines where it is desirable that machine components be easily installed or readily removed from the machine housing.

Referring to Figure 1. the two sections of the shaft are each fitted with a powder metal (iron base alloy) hub 2. Each hub 2 is fitted with three triangularly spaced- horizontally grooved pins (e.g.. drive-lok spring posts) 3 which are pressed into place. To assemble the coupling. an elastomeric 11011
ring 4 is placed near the base of the pins 3 on the hub 2 which is fitted with the longer coupling pins. When the second shaft 1 is located such that the pins 3 on its hub 2 are spaced between those on the first hub as in Figure 2b. the llOfl ring 4 is relocated to ride in the grooves of the six pins as shown in Figure 2a. The "0" ring may be of a variety of shapes. however. the rounded corner rhomboid shown in Figure 2b will allow the seating of the ring on the pins with a minimum of groove...
