Gear type hydraulic pump or motor - has axial ends of gears slanted to produce hydrodynamic lubrication of end face
The machine has two gears (12) meshing within a casing. The bearings for the shafts are in bushes between the gears and the endplates of the casing. The bushes are pressed against the end faces of the gears to provide correct axial location. The end face of each gear is cut at a slant so that a wedg...

| description | The machine has two gears (12) meshing within a casing. The bearings for the shafts are in bushes between the gears and the endplates of the casing. The bushes are pressed against the end faces of the gears to provide correct axial location. The end face of each gear is cut at a slant so that a wedge-shaped gap (S) is formed between the end of the gear and the face of the bush. The wedge shape widens in the direction of rotation of the gear. This results in hydrodynamic lubrication of the axial end of the gear with reduced friction and wear. |
