System for producing dynamic seal of hydrostatic motor to be mounted on wheel shaft of vehicle, has centering ring mounting dynamic lip seal floating on support plane with respect to shaft before its attachment to support plane

摘要

The system has a sealing member including a support (3) and a dynamic lip seal (4), where the support is provided with a centering surface (37) relative to a shaft (1). A screw (6) fixes the support on a support plane in a position defined by a centering ring (7), where the centering ring mounts the dynamic lip seal floating on the support plane with respect to the shaft before its attachment to the support plane. The centering ring allows centering of the dynamic lip seal with tolerance of 0.05 mm with respect to the shaft. Independent claims are also included for the following: (1) an assembly for producing a dynamic seal of a hydrostatic motor, comprising a friction track (2) a method for producing a dynamic seal of a hydrostatic motor.
