Problems solved by technology
It has the following problems: first, in the early stage of work, the bearing may not be lubricated in time and fully by the lubricating oil in the box, and due to the lack of self-lubrication, the bearing will have short-term poor lubrication of the steel ball and the groove; When the gearbox is working, the metal chips worn by the gears can easily enter the working surface of the bearing channel, which can easily cause the wear of the bearing channel, and then cause the loss of precision and early failure; the third is due to the excessive vibration of the motor operating environment, which increases Wear, make the temperature rise, the bearing is easily damaged, and the service life of the bearing is low

Embodiment Construction
[0015] Below in conjunction with accompanying drawing and embodiment the technical solution of the present invention is further described:
[0016] Such as figure 1 and figure 2 As shown: the present invention provides a self-lubricating deep groove ball bearing, including an inner ring 3, an outer ring 1, a cage 9 and steel balls 8, the cage 9 is stamped from a steel plate, and a lubricating gap is set on the edge of the cage 9 10. It is convenient for lubricating oil to enter between the cage 9 and the steel ball 8 for lubrication. Both the inner ring 3 and the outer ring 1 are provided with grooves, and a sealing ring 2 is arranged on the groove; Cavity, the diameter of the cavity is set to 5cm, the cavity is filled with lubricating oil 4, and an oil hole is arranged on the inner wall of the steel ball 8, and the oil hole includes a first necking section, an oil storage section 6 and a second necking section Section 5, the first necking section connects the oil storage ...

The invention relates to the technical field of bearings, particularly to a self-lubricating deep groove ball bearing. The self-lubricating deep groove ball bearing comprises an inner ring, an outer ring, a retainer and a steel ball, wherein grooves are formed in both the inner ring and the outer ring, and sealing rings are arranged on the grooves; a cavity is formed in the steel ball and filled with lubricating oil, and an oil hole is formed in the inner wall of the steel ball; a scraping piece is arranged on the inner wall, which is located between the retainer and the steel ball, of the retainer. With the adoption of the self-lubricating deep groove ball bearing, the temperature can be decreased, and whether a drill is damaged or not can be detected.
Description
technical field [0001] The invention relates to the technical field of bearings, in particular to a self-lubricating deep groove ball bearing. Background technique [0002] Deep groove ball bearings are the most commonly used rolling bearings. It is mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has the performance of a certain angular contact ball bearing and can bear combined radial and axial loads. [0003] When the supporting bearing used in the existing automobile gearbox works, it will be lubricated by the lubricating oil in the gearbox. It has the following problems: first, in the early stage of work, the bearing may not be lubricated in time and fully by the lubricating oil in the box, and due to the lack of self-lubrication, the bearing will have short-term poor lubrication of the steel ball and the groove; When the gearbox is working, the metal chips worn by the gears can easily enter the working surface of the bear...
