Seal between the rotor and stator of a swing drive system is a sealing bar with a core to form the clamping unit of an incompressible elastomer material for effective sealing over a wide temp range

摘要

The seal structure, for use between the stator and rotor of a swing drive, has a sealing bar (11) as a clamping unit (12) formed by a core of incompressible elastomer material, such as rubber. The clamping unit (12), in a longitudinal section, lies along a longitudinal side (13) and between the two axial end sides (14,15) of two sealing angle members (16,17), which can slide axially within each other in a telescopic action independently of the pressure on the clamping unit (12).
