Abstract: An improved seal (10) for use in a universal joint (11) having an elastic seal ring (23) compressed between a pair of right circularly cylindrical sleeves (24, 25). The seal ring is bonded to the sleeves. The sleeves are adapted to have press-fitted relationship with association portions of the universal joint, such as the journal trunnion (12) and the bearing retainer (14). In one form, the elongated extent of the sleeves is parallel to the axis (15) of the journal trunnion (12) and in a modified form, the sleeves (124, 125) extend perpendicularly thereto. In each form, a portion of one of the sleeves is disposed adjacent the inner end of the needle bearings (22, 122) so as to limit axial movement thereof. The sleeves are bonded to the seal ring so as to preclude sliding movement therebetween while yet permitting limited axial play in the universal joint thereby to provide long troublefree life of the seal.

Abstract translation: 一种用于万向节（11）的改进的密封件（10），其具有压缩在一对右圆形圆柱形套筒（24,25）之间的弹性密封环（23）。 密封环与套筒结合。 套筒适于与万向接头的关联部分（例如轴颈轴颈）和轴承保持器（14）具有压配关系。 在一种形式中，套筒的细长范围平行于轴颈轴颈（12）的轴线（15）并且以改进形式，套筒（124,125）垂直延伸。 在每种形式中，一个套筒的一部分邻近滚针轴承（22,122）的内端设置，以限制其轴向运动。 套筒粘合到密封环上，以防止其间的滑动运动，同时允许在万向节中有限的轴向游隙，从而提供密封件的长期无故障的使用寿命。
