Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bearings, in particular to a bearing with a reinforcement structure. Background Art
[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Due to the characteristics of bearings, bearings are used in many different fields. Therefore, it is necessary to reinforce the bearings to increase their strength and thus improve their service life.
[0003] A Chinese patent discloses a precision bearing structure with improved structural strength performance (authorization announcement number CN217977070U). The patented technology cooperates with the oil-absorbing sponge, the annular through-tube, the oil-filling nozzle and the sealing plug. Since the oil-absorbing sponge absorbs lubricating oil, the ball contacts the oil-absorbing sponge with lubricating oil during rotation. During the process, lubricating oil is promptly applied to the surface of the ball, reducing the friction between the outer ring and the inner ring of the precision bearing, extending the service life of the precision bearing structure, and the setting of the strength reinforcement support ribs improves the overall structural strength of the precision bearing structure.
[0004] However, there are still some shortcomings in this patent. Although this patent can reinforce the bearing by supporting ribs, it can be seen from the drawings of this patent that when reinforcing the bearing, it only uses supporting ribs to reinforce it, and the reinforcement effect is poor. In this way, the bearing will still be deformed and damaged after being subjected to a large external force. Therefore, those skilled in the art provide a bearing with a reinforcement structure to solve the problems raised in the above background technology. Utility Model Content

This arrangement utilizes the first reinforcing ribs 411 to make the strength of the first reinforcement layer 41 higher.
[0025] exist Figure 4 Middle: The second reinforcing ribs 431 are arranged in an "X" shape, and at least six groups of the second reinforcing ribs 431 are arranged inside the second reinforcement layer 43. This arrangement utilizes the second reinforcing ribs 431 to make the strength of the second reinforcement layer 43 higher.
