Novel bearing running in machine

Abstract

A novel bearing running in machine relates to the technical field of a special device for bearing. A motor (2) is arranged at the lower end of a body (1) and connected with a gearbox (3), the gearbox (3) is connected with a spindle (5) through a belt (4), the spindle (5) is installed in a spindle box (6), a clamping pressure cylinder (12) is arranged at the tail end of the spindle (5), an expansion sleeve (7) is arranged on the spindle (5), a bearing (8) is installed on the expansion sleeve (7), a pressure application head (9) is arranged on the bearing (8), the pressure application head (9) is connected with a pressure application device (10), and an oil feeding hole (11) is formed in the pressure application device (10). The novel bearing running in machine is simple in structure, convenient to use and convenient to clamp, greatly reduces bearing scrap, ensures bearing running in effects and quality and meets the requirement for batch production. The pressure can be controlled accurately.

Description

Technical field: [0001] The invention relates to the technical field of special equipment for bearings, in particular to a novel bearing running-in machine. Background technique: [0002] Bearings are components that fix and reduce the friction coefficient of loads during mechanical transmission. It can also be said that when other parts move relative to each other on the shaft, they are used to reduce the friction coefficient during power transmission and keep the center of the shaft fixed. Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of mechanical load during the transmission process of the equipment. According to the different friction properties of moving elements, bearings can be Divided into two types of rolling bearings and sliding bearings. [0003] The general processing technology in the bearing industry is to sell the bearing directly as a fin...

AI Technical Summary

Problems solved by technology

[0003] The general processing technology in the bearing industry is to sell the bearing directly as a finished product after processing and assembling, and generally does not perform running-in or running-in. With the development of society and the advancement of science and technology, the speed and rotation accuracy of the standard part of the bearing , noise and load-carrying capacity requirements are also getting higher and higher. At present, domestic railways have been speeding up for many times, and the requirements for heavy-duty railway bearings have been further improved. The quality of the bearing is greatly improved. Now the running-in of the bearing is installed on the main shaft of the ordinary lathe. When the main shaft is rotating, the carriage is pushed to the outer diameter of the bearing for running-in. The disadvantage is that it is inconvenient to install and disassemble, and the pressure cannot Accurate control, bearing temperature can not be detected, very inconvenient to use, can not meet the needs of mass production
