Pretensioning of a counter track type fixed joint by a bellows

摘要

The joint has outer and inner parts (12, 14), and a shaft (21) fixedly connected with the inner part, where bellows (24) seal the joint and consist of thermoplastic elastomer (TPE). The bellows are connected indirectly with the outer part at one end and fixedly with the shaft at another end. The bellows are so attached that an axial pressure pre-tensioning force is formed in the bellows, where the force stresses the outer part and the shaft axially away from each other.
