Feeding pressure medium from fixed housing to rotating shaft - involves shaft located against housing with considerable clearance and between housing and shaft are elastic seals with rectangular cross-section

摘要

The clearance (a) between the housing (1) and the shaft (2) is bridged over by paired elastic sealing components (6) arranged between the pressure feed channels and the bearings and tensioned against the housing (1), locating on the flanks of the rotor grooves (8). The sealing components can move radially and axially with radial clearance in the rotor grooves (8) of the shaft (2) and have a rectangular sealing cross-section. The sealing components (6) are of special moulded material and on their periphery have a dividing gap. In the shaft (2) starting from the rotor grooves (8) specially formed ribs (9) are machined in. USE/ADVANTAGE - To feed pressure medium from fixed housing to rotating shaft, ensuring long operating time with high pressure of medium.
