Abstract
A bearing device is provided with an oil storage space. The oil storage space is an oil storage space that is formed in the bearing device, so that the lubricating oil stored in the oil storage space may gradually leak outward through the capillary pores of the bearing device, thereby slowing down the release velocity of the lubricating oil, and thereby increasing the lifetime of the bearing device.
Claims6
A bearing device, comprising:
- a first ring, having a shaft hole for passage of a rotation shaft of a rotor, said shaft hole having an inner wall defining a slot hole having a greater inner diameter, said slot hole forming a double-diameter stepwise hole;
- a second ring, having a shaft hole for passage of said rotation shaft of said rotor, said second ring having an outer wall placed in a smaller diameter portion of said double-diameter stepwise slot hole of said first ring, so that said slot hole of said first ring forms an oil storage space for storing a lubricating oil, said second ring having capillary pores so that said lubricating oil may leak outward.
