ABSTRACT:
A seal arrangement for providing a reliable seal between a shaft and an opening through which the shaft passes where the shaft undergoes both rotary and axial movement relative to the opening. The seal assembly consists of a seal suitable for relative rotary motion between the gasket surface and the surface to be sealed, a sleeve, and a seal suitable for sealing when there is relative axial movement between the seal and the sealed surface. The sleeve is used to isolate the rotary and axial motion of the shaft into two components so that each seal will only see one type of motion. In order to accomplish this, the sleeve is restrained from axial motion relative to the opening and has synchronous rotary motion with the shaft. This seal arrangement is particularly useful in pivotable drive assemblies where the use of a simple universal joint will impose a reciprocating motion on a drive axle.
