Fault identification method of bearing


It is very important to identify or predict the failure of bearings in operation without disassembly inspection, which is very important to improve productivity and economy.

The main identification methods are as follows:

1) Identify by sound.

Recognition by sound requires rich experience. Must be fully trained to be able to distinguish between bearing sound and non-bearing sound.

To this end, we should try our best to carry out this work by special personnel. The sound of the bearing can be clearly heard by sticking a listening device or a listening stick on the housing.

2) Identification by working temperature.

This method is a comparative identification method, which is only used in situations where the operating state is not changing much. Therefore, it is necessary to record the temperature continuously.

When a fault occurs, the temperature will not only rise, but also change irregularly.

This method is suitable to be combined with voice recognition method.

3) Identify by the state of lubricant.

Sample and analyze the lubricant, and judge whether it is mixed with foreign matter or metal powder by its dirty degree.

This method is especially effective for bearings or large bearings that cannot be observed close.

Installation of rolling bearing-heating installation method

Image
When the inner diameter of the bearing is greater than 70mm, or the fit interference is large, the bearing hole is expanded by heating, which saves labor and time in installation and avoids damage caused by excessive force. At this time, what needs to be controlled is the heating temperature. Generally, it is enough to heat the bearing to 80℃, up to 100℃. If the temperature exceeds 120℃, the bearing will be tempered, which will reduce the hardness and accuracy of the ring. Commonly used heating methods are: 1 electric heating plate heating method Put the bearing on an electric heating plate with a temperature of 100℃ for a few minutes. This method is the simplest. If the bearing is turned over several times, it can be heated evenly and the efficiency is high. This method can be used for both large and small bearings. 2 electric furnace heating method The bearing is heated in a closed automatic temperature control electric furnace, which has the advantages of uniform heating, accurate t...

Repair conditions and best methods of rolling bearing

Image
  Rolling bearings are mass-produced mechanical parts, and the manufacturing accuracy is very strict, and the degree of technical specialization is very high. Therefore, for the vast majority of bearing varieties that are easy to buy, it should be more cost-effective to buy than repair. Only under the following circumstances can the bearing repair be considered, namely: (1) The failure forms of a large number of bearings of the same model used in large factories are mainly the wear, fatigue or fretting of rolling surfaces, especially the damaged parts are mostly cages or rolling bodies, and the rings or washers still have repair value; (2) Large and extra-large bearings are on the verge of failure, or have failed without major damage to parts, or expensive bearings must try to extend their effective service life; (3) Some bearing varieties that are really difficult to buy have to be repaired without spare parts after failure, especially imported bearings; (4) The bearing is slightl...
