ABSTRACT:
A sealing device for a drive line slip yoke includes a generally resilient seal and a substantially rigid cover that cooperate to provide a fluid-tight seal at the interface between a slip yoke and an axially moving splined shaft. The seal has a mounting portion that includes a shoulder received within a groove defined on an outer surface of the slip yoke. The cover is snapped over the seal and maintained in position by cooperating tabs on the cover and a groove defined on an outer surface of the seal. The seal includes a sealing portion having three axially spaced and radially inwardly extending lips. A middle lip acts as an O-ring that serves as a back-up in the event that one of the other two lips becomes damaged or deteriorates with use. The substantially rigid cover serves to maintain the seal in proper engagement with the end of the slip yoke and protects the seal from damage potentially caused by debris encountered during operation. A sealing device designed according to this invention is especially useful in applications that require that lubricant be maintained in the slip yoke over long periods of time and during extensive use.
