Three identification methods of bearing faults: sound recognition, temperature identification, and state recognition of lubricants

Release time:2015/4/19 12:03:51

Bearing as the precision parts of mechanical equipment, how to improve the productivity of the factory, first of all, mechanical equipment performance must be the best, and the relationship between the performance of mechanical equipment use one of the largest bearings. Therefore, the factory in production and processing, must be in the machinery and equipment in the bearing for good inspection. For the sake of safety, China bearing network shared bearing fault identification method of three, I hope to help everyone.

1. Recognize by sound

Sound recognition requires a lot of experience. Adequate training is required to identify bearing sound and non bearing sound. For this reason, we should try our best to do this work by special person. The sound of the bearing can be clearly heard with a listening device or an acoustic stick attached to the shell.

2, through the working temperature to identify

This method belongs to the method of comparative identification, which is only used in the situation where the running state is not changed. For this reason, continuous temperature records must be carried out. When the fault occurs, the temperature will not only rise, but also change irregularly. The method and the method of sound recognition are suitable.

3. Identify the state of the lubricant

Sampling and analysis of lubricants, through the degree of contamination, whether mixed foreign body or metal powder did not wait to determine. This method is especially effective for bearings or large bearings which can not be close to observation.
