Application Of Vibration Maintenance Technology For Middle Spherical Roller Bearings

What is Spherical roller bearings

The Spherical roller bearings has a double row of rollers, and the outer ring has a common spherical raceway, and the inner ring has two raceways and is inclined to an Angle relative to the bearing axis.This ingenious structure enables it to have automatic self-aligning performance, so it is not susceptible to the influence of the Angle between the shaft and the bearing box seat on the error or shaft bending. It is suitable for the occasion of Angle error caused by the installation error or shaft deflection.The bearing can bear radial load as well as axial load for bidirectional use.

Characteristics of Spherical roller bearings

Spherical roller bearings with two rows of rollers, mainly to bear radial load, but also can bear axial load in any direction.High radial load capacity, especially suitable for heavy load or vibration work, but can not withstand pure axial load.The outer ring raceway of this kind of bearing is spherical, so it has good self-aligning performance and can compensate the coaxiality error.

Application of Spherical roller bearings

Paper making machinery, reducer, railway vehicle axles, rolling mill gear box bearing block, rolling mill roller, crusher, vibrating screen, printing machinery, woodworking machinery, various industrial reducer, vertical self-aligning bearing with belt seat.

Application of vibration maintenance technology for middle spherical roller bearings

Vibration Signal Analysis and Diagnosis Method of Spherical Roller Bearings By analyzing the vibration signal of rolling bearing with the frequency spectrum, the hidden trouble can be found in time and the fault reason of rolling bearing can be accurately diagnosed.

1. Analysis from the perspective of frequency

It can be seen that different fault causes correspond to different frequencies. The vibration frequency caused by the assembly structure is very small. When the spherical roller bearing components have serious manufacturing defects or serious damage, the vibration frequency will be significantly increased.

2.From the impact pulse energy analysis

When the spherical roller bearing elements have minor damage, the pulse value is very small. With the development of the fault, the pulse value gradually increases, and the vibration intensity also increases significantly.

3. Monitoring methods

Relative judgment standard can be used to judge whether the equipment is normal or not according to the spectrum diagram.

The lubrication time interval has a simple premise: to maintain the proper operation of the equipment without the spherical roller bearings ceasing operation due to drying and collapse. This is a fixed concept of prevention. But we have to strike a balance between hunger for lubrication and a lot of over-lubrication.

Traditionally, the lubrication schedule is based on time. Equipment suppliers usually make lubrication plans based on operating time. And equipment suppliers often include guidance on the amount of lubricating oil in their maintenance planning process.
