ABSTRACT:
A viscous shear coupling comprises a housing and a hub rotatable within the housing. Plates are splined to the housing and plates to the hub, there is a pair of plates splined to the hub between each two adjacent plates splined to the housing. The plates in pairs splined to the hub have convergent apertures therein, each aperture converging in a direction away from that radial face of the plate which is adjacent to the other plate of the pair.
