Bearing cap for universal joint having anti-rotation protrusions

摘要

A structure restrains a bearing cap mounted on a universal joint cross from rotating relative to an end yoke connected thereto during use. The bearing cap has a plurality of axially extending protrusions provided on its end surface. In a first embodiment of the invention, the bearing cap is connected to a half round end yoke, and means are provided for engaging the protrusions to prevent rotation of the bearing cap relative to the half round end yoke. A preferred structure for this is a nib formed integrally with the half round end yoke arm, wherein the nib extends over the end of the recess and engages the protrusions to prevent rotation. A second embodiment includes a half round end yoke and a retainer strap for retaining the bearing cap within the recess of the yoke arm. The retainer strap includes a flange portion extending partially across the end surface of the bearing cap. The flange portion includes a slot positioned to engage the protrusions to prevent rotation. A third embodiment includes a half round end yoke and a retainer strap including a pair of flange portions extending partially across the end surface of the bearing cap. The flange portions define a gap therebetween to engage the protrusions to prevent rotation. A fourth embodiment includes a full round end yoke and a retainer strap extending completely across the end surface of the beating cap. The retainer strap engages the protrusions to prevent rotation. A fifth embodiment includes a full round end yoke and a spring tab including a flange portion extending partially across the end surface of the bearing cap. The flange portion is positioned to engage the protrusions to prevent rotation.
