Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bearings, in particular to a long-life bearing. Background Art
[0002] Rolling bearings are precision mechanical components that convert the sliding friction between the rotating shaft and the shaft seat into rolling friction, thereby reducing friction losses. Rolling bearings are generally composed of four parts: inner ring, outer ring, rolling element and cage. The inner ring is used to match the shaft and rotate with the shaft, and the outer ring is used to match the bearing seat and play a supporting role. The rolling element is evenly distributed between the inner and outer rings with the help of the cage. Its shape, size and number directly affect the performance and life of the rolling bearing. The cage can evenly distribute the rolling element, guide the rolling element to rotate and play a lubricating role.
[0003] Based on the above, the inventors have found the following problems: During long-term operation of existing bearings, due to friction and heat, the bearings will generate a large amount of heat. If the heat generated by the bearings cannot be dissipated in time, it will cause wear and deformation of the bearings, thereby reducing the service life of the bearings.
[0004] Therefore, in view of this, the existing structure and defects are studied and improved to provide a long-life bearing in order to achieve the purpose of having more practical value. Utility Model Content

Since the conduction ring is fitted with the inner wall of the heat-conducting ring on the side away from the circular holes, the heat-conducting ring absorbs the heat on the conduction ring, and the heat dissipation ring is fitted with the heat-conducting ring, so that the heat dissipation ring dissipates the heat from the heat-conducting ring.
[0009] Furthermore, the heat dissipation ring is provided with a plurality of first through holes, and the heat conductive ring is provided with a plurality of second through holes, which are located on the same axis relative to the first through holes and the second through holes.

[0013] Furthermore, an oil guide ring is embedded in one of the hollow plates, and a plurality of oil guide pipes are installed at the bottom end of the oil guide ring. The plurality of oil guide pipes all penetrate through one of the hollow plates and extend to the outside.
[0014] The beneficial effect of adopting the above further solution is that, through the coordinated use of the oil guide ring and the oil guide pipe, the lubricating oil inside the oil guide ring can enter the bearing through a plurality of oil guide pipes, thereby improving the efficiency of injecting the lubricating oil into the bearing.

For the long-life bearing, when heat is generated inside the bearing due to friction, a plurality of circular holes are arranged on the outside of the raceway, and the outside of the raceway is fitted with the conduction ring, so that the heat inside the bearing contacts the conduction ring through the circular holes, and then the heat inside the bearing is transferred to the cavity inside the outer ring of the bearing. Since the conduction ring is fitted with the inner wall of the heat-conducting ring on the side away from the circular hole, the heat-conducting ring absorbs the heat on the conduction ring, and the heat dissipation ring is fitted with the heat-conducting ring, so that the heat-dissipating ring dissipates heat from the heat-conducting ring. By arranging the first through hole and the second through hole, since the corresponding first through hole and the second through hole are located on the same axial center line, it is convenient for air to circulate inside the cavity of the outer ring of the bearing through the first through hole and the second through hole, thereby further improving the heat dissipation efficiency.
