ABSTRACT:
A slip joint seal for a driveshaft is between two universal joint yokes. A male splined shaft rotates with a first yoke and a female splined shaft rotates with a second yoke, with the two being mechanically engaged for slidable but nonrotational movement during operation of the driveshaft. A sealing sleeve extends from the first yoke around the male splined shaft and is of a larger diameter than the female splined shaft. The female splined shaft has a single, outwardly-facing, annular seal at its outer end, away from the second yoke, which seal engages the inner surface of the sealing sleeve. The female splined shaft also has a grease fitting for supplying grease to the shafts, with excess grease being capable of passing by the seal, which also acts as a wiper to remove contaminants within the sealing sleeve.
