Abstract
The present invention relates to a bearing device including a body formed with an inner groove that does not communicate with the shaft hole of the body. Thus, when the rotation shaft is rotated, the lubricating oil may lubricate the rotation shaft, and may flow back to be stored in the inner groove after the rotation shaft stops rotating, thereby achieving the effect of recycling use. At the same time, the inner groove does not communicate with the inner shaft hole, such that when the rotation shaft is rotated, the lubricating oil contained in the inner groove will not be directly carried out of the body and will not sputter out of the body. Thus, the amount of loss of the lubricating oil may be reduced, thereby increasing the lifetime of the bearing device.
Claims6
A bearing device for a shaft, said bearing device comprising:
- a body having a shaft hole with an annular inner groove and an end flange, the end flange forming an axial hole;
- and
- a porous inner bearing, disposed in the shaft hole to insulate the inner groove, the inner bearing having an inner bearing end corner adapted to engage with the end flange where the end flange radially extends past the inner bearing end corner;
- wherein a shaft can extend through the shaft hole of the inner bearing and the axial hole of the body successively when operating.
