Abstract
The invention relates to a subassembly, consisting of a drive shaft ( ), a housing ( ) with a through-bore ( ), through which the drive shaft projects out of the housing and an axial mechanical seal consisting of a rotating seal ring ( ) and a counter-ring ( ) which forms a seal between the drive shaft ( ) and housing ( ) components. The invention aims to improve the assembly of the axial mechanical seal and the thermal dissipation from said mechanical seal. To this end, the counter-ring ( ) is configured as one single piece with one of the two components ( ). This obviates a separate assembly of the counter-ring and allows the heat produced by friction to be dissipated directly into one of the two components.
