Abstract
In order to ensure full-surface thrust contact and coverage despite a low production and assembly outlay, even if the bearing is mounted slightly askew, a thrust and cover washer may be used which includes an inelastic first annular washer part axially thrusting and not contacting the rotor shaft, and an elastic second annular washer part positively joined thereto and resting sealingly on the rotor shaft. The first annular washer part may advantageously be made of plastic and the second annular washer part may advantageously be made of an elastomer.
Claims34
A thrust and cover washer for a bearing of a rotor shaft, wherein the thrust and cover washer is mounted on the rotor shaft, the thrust and cover washer comprising:
- an axially thrusting inelastic first annular washer part which is not in contact with the rotor shaft;
- and
- an elastic second annular washer part positively joined to the rotor shaft and resting sealingly on the rotor shaft, wherein the thrust and cover washer is mounted on the rotor shaft between a spherical cap bearing and a commutator of a commutator motor.
A thrust and cover washer for a bearing of a rotor shaft, wherein the thrust and cover washer is mounted on the rotor shaft, the thrust and cover washer comprising:
- an axially thrusting inelastic first annular washer part made of plastic, which is not in contact with the rotor shaft;
- and
- an elastic second annular washer part made of an elastomer positively joined to the rotor shaft and resting sealingly on the rotor shaft.
A thrust and cover washer for a bearing of a rotor shaft, wherein the thrust and cover washer is mounted on the rotor shaft, the thrust and cover washer comprising:
- an axially thrusting inelastic first annular washer part which is not in contact with the rotor shaft;
- an elastic second annular washer part positively joined to the rotor shaft and resting sealingly on the rotor shaft;
- and
- axial and radial undercuts in the form of a retaining ring surrounded axially and radially inwardly by the second annular washer part and projecting radially inward, in the edge region of the rotor shaft opening of the first annular washer part, for mutual positive axial and radial immobilization between the first annular washer part and the second annular washer part.
A thrust and cover washer for a bearing of a rotor shaft, wherein the thrust and cover washer is mounted on the rotor shaft, the thrust and cover washer comprising:
- an axially thrusting inelastic first annular washer part which is not in contact with the rotor shaft;
- an elastic second annular washer part positively joined to the rotor shaft and resting sealingly on the rotor shaft;
- and
- tangential undercuts for mutual positive tangential immobilization between the first annular washer part and the second annular washer part.
A thrust and cover washer for a bearing of a rotor shaft, wherein the thrust and cover washer is mounted on the rotor shaft, the thrust and cover washer comprising:
- an axially thrusting inelastic first annular washer part which is not in contact with the rotor shaft;
- an elastic second annular washer part positively joined to the rotor shaft and resting sealingly on the rotor shaft;
- and
- a push-on axial join between the first annular washer part and the second annular washer part.
