High Rotary Bearing Precision
- Sep 18, 2017 -

Plain bearings are usually said to be plain, with a simple form, large contact area, if the lubrication remains good, anti-wear performance will be very good, bearing life will be very long. The bearing capacity of sliding bearing is large, the rotary precision is high, and the lubricating film has an impact-resisting effect. So it has been widely used in engineering. But his biggest drawback is the inability to maintain sufficient oil reserves and, Slide Bearings once the lubricant is insufficient, it immediately causes severe wear and failure.

Sliding bearings are classified in three ways:

Sliding bearing according to the direction of bearing load can be divided into: thrust sliding bearings and radial bearings

According to the lubrication film formation principle is divided into: dynamic pressure sliding bearing and hydrostatic bearing

According to the structure of different types can be divided into: integral sliding bearing split

Features: Compared with rolling bearings, sliding bearing has the characteristics of high bearing capacity, good seismic resistance, Slide Bearings stable and reliable work, low noise and long life. Slide Bearings It is widely used in internal combustion engines, rolling mills, large motors and meters, radars, telescopes and so on.

Sliding bearings are often used in mechanical assembly, repair process will often meet the disassembly, cleaning, assembly work, this paper briefly on the characteristics of the sliding bearing, assembly requirements, technology and attention to the issues are briefly described.

Bearing liner of sliding bearing is directly contacted with the axle neck, in order to ensure the good working performance of the sliding bearing, in addition to the proper lubrication measures, the material performance of the bearing should meet the following requirements: (1) to have sufficient strength and plasticity, Slide Bearings so that the bearing liner can withstand a certain working pressure, and the pressure distribution between it and the axle neck evenly; (2) Good running, antifriction and wear resistance, Slide Bearings so as to prolong the service life of bearing liner, (3) Good lubrication and heat dissipation performance and good process skills.

The assembly requirement of sliding bearing is that the contact viscosity of the shaft and the bearing surface should meet the prescribed standard, Slide Bearings and in the working conditions, the shaft or bearing should not be burnt out, and the position of the lubricating oil channel should be correct and smooth to ensure full lubrication.
