Abstract

1531726 Resilient couplings CAM GEARS Ltd 21 Oct 1975 [29 Nov 1974] 51811/74 Heading F2U [Also in Division B7] A resilient coupling comprises an input shaft 5, an output shaft 1 and a spring 16 which in its unstressed condition lies in a single plane with bent-out ends 17, 18 engaging in bores of a flange 7 of input member 5 and a member 9 pinned to the output shaft 1. Two springs 16, 16a are provided in the embodiment shown, each being an interrupted annulus (Fig. 1A, not shown). The ends of a spring 16, 16a may be bent out radially rather than axially as shown. A plurality of springs may be mounted concentrically (Fig. 5, not shown). A spiral spring may be used (Fig. 4, not shown). In the embodiment shown there is helical movement between the output and input members 5, 1 due to pins 15 from flange 7 engaging in helical slots 14, the axial component of this moving a valve operating rod 3. The coupling is to be incorporated in steering gear in which servo pressure for assisting the steering is controlled in dependence on applied torque. A valve operated by a rotary movement may be used, in which case the helical grooves 14 are replaced by circumferential grooves. Input member 5 is connected to a steering column and output member 1 is a pinion shaft.
