Abstract
In a universal joint having a trunnion cross including trunnions defining a centerline extending centrally therethrough and trunnion cross support members which include a yoke defining a yoke bore and a bearing bush received within the bore and receiving therein the trunnions, an improvement is provided in that the trunnion cross support members are formed with at least one conical surface configured to taper away from a plane containing the centerline of the trunnion in a direction outwardly from the center of the universal joint. Conical surfaces may be formed on opposite sides of the trunnion centerline to extend an angular distance circumferentially which is greater than twice the bending angle of the joint. The conical surfaces may be formed either on the walls of the yoke bore or on the bearing bush.
