Bearings have always been very important rotating parts in automated and non-automated machinery, so we must always understand his working conditions in production and work, and in the event of damage or failure, we will not stop the operation of the machine. Maintain the bearings. Real-time monitoring is a good method, but not all mechanical equipment is equipped with such advanced equipment as real-time monitoring. Therefore, in the absence of such equipment, the users and maintenance personnel of our equipment must be highly vigilant about the signals sent by the bearings, such as vibration, noise, temperature and other abnormal phenomena, must not be ignored. Diagnose as early as possible.
First of all, we can roughly judge the working condition of the bearing through the sound. The experienced staff will use the electronic stethoscope to check whether the sound of the parts is normal. For example, the bearing of a linear guide usually makes a "wheeze" sound when it is working normally. If it makes a sharp hissing or squeaking sound or other irregular sounds, then we need to check it carefully. Our linear guide bearings are out.
When there is a squeak, it is generally due to insufficient lubrication or unreasonable selection of the bearing clearance of the linear guide. Moreover, if improper operation during installation, such as knocking scars, noise will be generated, and in this case, the noise emitted by the bearing will vary with its rotation speed.
If there is an intermittent noise, it may be that the rolling parts are damaged, or the toilet noodles may be crushed. And if it makes a hissing noise, there may be contaminants in the bearings of the linear guide. When there is a loud noise, then unfortunately, your bearing must have been seriously damaged.
Although the bearings of linear guides can be used for a long time to tell the quality of the parts, but in this case, some major situations have occurred and need to be dealt with immediately, so there is a certain hysteresis .
