Small Scale Quarry Stone Crushers Bearing Installation Steps

As an important part of mechanical equipment, the bearing is related to the normal operation of the Small Scale Quarry Stone Crushers, and whether the bearing is correctly installed is related to the service life of the Small Scale Quarry Stone Crushers bearing, so we must pay attention to it. This article mainly introduces the installation steps of the Small Scale Quarry Stone Crushers bearing, I hope to help everyone.

1. Use Professional Bearing Installation And Disassembly Special Tools

Advanced mounting tools to avoid bearing damage due to improper tooling and handling during installation. For example, when installing the Small Scale Quarry Stone Crushers bearing, the staff used the copper rod knock-in method, which easily caused the bearing axial force to be uneven, causing the cage to deform, the rolling element to be damaged, the clearance to become large, and the copper rod in the tapping process. In the middle, the copper ends fly into the bearing cage, which is easy to cause the Small Scale Quarry Stone Crushers bearing failure.

2. Check The Small Scale Quarry Stone Crushers Bearing Before Installation.

For old bearings, check the ball (column) surface for burrs, scratches, and cracks. Whether the radial clearance and axial clearance of the old bearing are qualified, generally only the radial clearance is measured.

For new bearings, first check the Small Scale Quarry Stone Crushers bearing model is correct. For example: Model 6318 deep groove ball bearing, bearing inner diameter of 90mm, its radial clearance range is 0.016 ~ 0.046mm, can also be found that the maximum wear of the Small Scale Quarry Stone Crushers bearing is 0.25mm.

3. Check The Fit Size Of The Small Scale Quarry Stone Crushers Bearing And The Rotor Shaft

When assembling the motor, it is necessary to carefully check the fit size of the bearing and the rotor shaft when the bearing is installed, and the fit size of the outer ring of the Small Scale Quarry Stone Crushers bearing and the end cover hole.

4, Control The Number Of Bearings And Bearings Indoor Oil

Excessive oil in the bearing and the box will cause the rolling elements of the bearing to slip, causing the rolling body to become sliding friction by rolling friction, damaging the bearing rolling body. Due to excessive bearing oil, the free space in the bearing housing is small, and the bearing of the Small Scale Quarry Stone Crushers is operated. The temperature will rise, the lubricating oil film of the rolling body will become thinner, the lubrication condition will be poor, the bearing noise will be easily caused, the surface will be slippery, and the life of the Small Scale Quarry Stone Crushers bearing will be shortened.

In the actual working process, for the Small Scale Quarry Stone Crushers bearing running at high temperature and high speed, the bearing with sealing surface should be used as little as possible, the oil content of the motor oil cover should be increased, and the fueling nozzle should be installed to improve the operating life of the motor bearing.

5, Pay Attention To Ensure That The Insulation Is Intact

For Small Scale Quarry Stone Crushers bearings with insulated design on the outer ring, care must be taken to ensure that the insulation is intact. If the Small Scale Quarry Stone Crushers bearing insulation is damaged during installation, the thin bearing oil film will be broken by the shaft voltage. After the oil film breaks down, not only the rolling element lubrication condition is bad, but also the electric spark generated will cause electric corrosion of the bearing rolling body, causing The surface of the rolling element is not only light, which accelerates the wear of the Small Scale Quarry Stone Crushers bearing.
