Single-row cylindrical roller bearing with outer retainer ring for overloading

Abstract

The invention discloses a single-row cylindrical roller bearing with an outer retainer ring for overloading, and belongs to the technical field of mechanical bearing parts. The bearing comprises an outer ring (1), an inner ring (2), a retainer (3) and a row of conical roller set (4). Compared with the prior art, the single-row cylindrical roller bearing with an outer retainer ring for overloading has the advantages of greatly reducing friction, improving lubricating conditions, improving lubricating quality and reducing friction heat and energy consumption loss so as to greatly prolong the service life of the bearing, and is simple in structure, convenient to control, high in reliability, convenient to maintain and the like.

Description

technical field [0001] The invention belongs to the technical field of mechanical bearing parts, more specifically, it belongs to a heavy-duty single-row cylindrical roller bearing with an outer retaining ring. Background technique [0002] The bearing structure is composed of inner ring, outer ring, roller and cage. Heavy-duty bearings are used on rolling mills in various rolling mills and wind turbines. Bearings work under impact, high temperature, high speed, heavy load, poor lubrication, and high-pressure water erosion. , dust and other harsh working conditions. During the working process of the bearings used in rolling mills, foreign objects such as impurities, cooling water, iron scale, etc. enter the bearings. When the new bearings are just used, the sealing effect is good, but after a period of use, the sealing effect becomes poor. In this case, if If the seals are not replaced in time, the sealing effect will be very poor. In addition, frequent assembly and disasse...

AI Technical Summary

Problems solved by technology

During the working process of the bearings used in rolling mills, foreign objects such as impurities, cooling water, iron scale, etc. enter the bearings. When the new bearings are just used, the sealing effect is good, but after a period of use, the sealing effect becomes poor. In this case, if If the seals are not replaced in time, the sealing effect will be very poor. In addition, frequent assembly and disassembly of bearings will affect the sealing. Foreign matter such as iron oxide scale and cooling water generated during the rolling process will enter the bearing, and the lubricating grease will also leak out. , This will cause non-fatigue damage to the bearing, reduce the service life of the bearing, and increase the workload of workers who often add grease, as well as the amount of grease used and discharged, causing environmental pollution

[0003] Fans are usually used in deserts and other occasions, and the working environment of fans is also very harsh. The bearings used in fans also encountered technical problems similar to those encountered in rolling mill bearings. After a period of time, the sealing effect will become poor. In this case, if the seal is not replaced in time, the sealing effect will be very poor. In addition, frequent bearing assembly and disassembly will affect the sealing. It will enter the bearing, and the lubricating grease will also leak out, which will cause non-fatigue damage to the bearing, reduce the service life of the bearing, and increase the workload of workers who often add grease, as well as the amount of grease used and discharged. The pollution inside the fan, how to effectively improve the service life of the bearing in the fan is also an important factor restricting the working life of the fan
