There are three main causes of noise from rolling bearings: bearings have dust, scars, and improper lubricants. The following will answer them one by one.

Noise from bearings caused by dust

If non-periodic vibration occurs in the bearing, and the size of the vibration and noise varies from time to time, it may indicate that there is foreign matter such as dust in the bearing.

The method to solve the noise caused by the dust caused by the bearing: First, the cleaning method of the INA bearing can be improved, and the bearing, the shaft, the seat hole and the matching parts should be thoroughly and thoroughly cleaned before the device. Er Su Qing foreign matter in the smoothing agent. Three improved bearing seals. Fourth, to prevent the use of plastic materials or foreign objects embedded in plastic sticks.

Flaw causes bearing noise

If the bearings will experience periodic vibration and noise like riveting rivets, the period can be fixed, but most of them have a corresponding relationship with the speed, indicating that the rolling bearing's rolling surface has cracks, indentations or rust. In the course of consumption of air compressor bearing parts, there are many cold and hot working processes. In order to satisfy the requirements of small amount, high efficiency and high quality, the bearing steel should have good processing performance. For example, cold and hot forming properties, cutting performance, hardenability, etc.

The method for solving the noise caused by the damage of the bearing: when the device is not knocked, avoid tilting the bearing when the bearing is assembled with the shaft and then installed in the bearing seat. Avoid bearing corrosion during storage and avoid shock and vibration during transportation. Third, the use of high viscosity smooth grease.

Improper lubricant causes noise in bearings

If the bearing will make irregular noise, it indicates that the bearing is improperly lubricated.

The method to solve the bearing noise caused by improper lubricant: Improper lubricant can be divided into three categories: First, the wrong lubricant is selected. EASE bearing A rolling bearing composed of a combination of the above two bearing structures at the same time in a set of bearings. Such as needle roller and thrust cylindrical roller combined bearings, needle roller and thrust ball combined bearings, needle roller and angular contact ball combined bearings, etc. Two lubricants are missing. Three lubricants age and harden. To select a suitable lubricant, the lubricant should be added according to the amount of lubrication, and the lubricant should be changed regularly.

Improper lubricants are not terrible to make bearing noise, scars are not terrible to make noise, and dust is not to be afraid of noise, because we all have solutions.
