Abstract
A hydrodynamic bearing assembly comprises a bearing (10) defining a bearing hole (12) therein, a shaft (20) rotatably received in the bearing hole with a bearing clearance formed between a bearing surface of the bearing and an outer surface of the shaft, and a cover (40) attached to a top end of the bearing. The bearing clearance is filled with lubricant. A locking groove (22) is formed in an outer periphery of the shaft. The cover defines a through hole (42) receiving the shaft at the locking groove. Interlocking devices are formed on the cover and the bearing to join the cover and the bearing.
Claims22
A hydrodynamic bearing assembly comprising:
- a bearing defining a bearing hole therein;
- a shaft rotatably received in the bearing hole with a bearing clearance formed between a bearing surface of the bearing and an outer periphery of the shaft, the bearing clearance filled with lubricant, a locking groove being formed in the outer periphery of the shaft;
- a cover attached to a top end of the bearing, the cover defining a through hole receiving the shaft at the locking groove;
- wherein
- interlocking devices are formed on the cover and the bearing to join the cover and the bearing.
A hydrodynamic bearing assembly comprising:
- a bearing;
- a shaft rotatably received in the bearing with lubricant filled between the shaft and the bearing;
- and
- a cover attached to the shaft and the bearing to enclose the lubricant in the bearing and limit movement of the shaft in an axial direction relative to the cover.
A bearing assembly comprising:
- a bearing defining a hole therein;
- a shaft rotatably received in said hole of said bearing and installed into said hole along a direction substantially parallel to a rotation axis of said shaft in said hole;
- and
- a cover installed between said shaft and said bearing and used to prevent said shaft from movement along a reverse direction relative to said installing direction of said shaft.
