Mechanical equipment and bearing thereof

Abstract

The embodiment of the invention provides mechanical equipment and a bearing thereof. The bearing comprises an inner bearing ring, a bearing sealing part and an end portion scraper, wherein the inner bearing ring is of a ring structure, a roller of the bearing is located on the outer side of the inner bearing ring, the bearing sealing part is assembled on the external circumference face of the inner bearing ring and seals the bearing, and the end portion scraper is fixed to the external circumference face of the inner bearing ring or the inner end face of the bearing sealing part, is located inthe space defined by the outer end face of the roller, the inner bearing ring and the bearing sealing part, and collects and guides lubricants to flow towards the roller. According to the mechanicalequipment and the bearing thereof provided by the embodiment of the invention, the distribution situation of the lubricants in the bearing and the lubrication situation of a work contact face inside the bearing are well improved.

Description

technical field [0001] The embodiments of the present invention relate to the mechanical field, and in particular to a mechanical device and a bearing thereof. Background technique [0002] Bearings are important parts in existing mechanical equipment, which are arranged between relatively rotating parts to reduce mutual friction and improve the rotation accuracy of the rotating shaft. [0003] Bearings include bearing inner ring, bearing outer ring, sealing ring and rollers (or needle rollers, balls, rollers, etc.). The contact force and relative sliding between the rings will produce sliding friction. Therefore, it is necessary to install lubricating grease inside the bearing to prevent the problem of excessive temperature rise of the overall bearing and premature failure of the bearing due to poor lubrication. [0004] At present, the lubricating grease of the bearing is generally filled before installation, and then new grease is added through the oil filling hole after...

AI Technical Summary

Problems solved by technology

However, taking the double-row tapered roller bearing as an example, it can be found that a large part of the grease is stored in the non-contact area of ​​the bearing such as the middle gear ring, sealing ring, and inner ring rib by disassembling the bearing after a period of lubrication, while the bearing There is very little grease on the internal contact surface, that is, only by adding grease can not fundamentally ensure the improvement of the lubrication of the internal contact surface of the bearing, and even lead to excessive lubrication and waste of grease

[0005] Of course, it is also possible to relubricate the bearings by shutting down and disassembling, but this will lead to increased workload and increased costs
