Sealing arrangement for a telescopic drive shaft with universal joints

摘要

The cardan joint is assembled of a first shaft (5) with inner teeth and a second shaft to be moved along the toothed area by engaging its outer teeth with the inner teeth located at the first shaft (5). A sealing sleeve (311) envelops the joint area between the shafts. The sleeve (311) is bent three times (317, 318, 319) at one of its edges (313) in order to provide a space (320) for the insertion of a specifically shaped elastic sealing ring (311) comprising a circular groove (28) and at least one sealing lip (323) touching the outer surface (10) of the shaft (5).
