Composite composite bearing belongs to fine parts
Author:admin Date:2022-10-13
Composite composite bearings are fine parts, so they should be used with great caution. Even if the high-performance composite bearing is used, if it is not used properly, the expected performance effect cannot be achieved, and the composite bearing is easy to be damaged. Therefore, the following items should be noted when using composite bearings:
1、 Keep the compound bearing and its surrounding environment clean. Even if invisible dust enters the compound bearing, it will increase the wear, vibration and noise of the compound bearing.
2、 When using the device, be careful. It is not allowed to punch hard. It is not allowed to directly hit the composite bearing with a hammer. It is not allowed to transmit pressure through the rolling element.
3、 Use appropriate and accurate devices and tools, try to use special tools, and try to prevent the use of cloth and short fibers.
4、 Avoid corrosion of composite bearing. When taking the composite bearing directly by hand, you should fully wash the sweat on your hands and apply high-quality mineral oil before stopping the operation. Pay special attention to rust prevention in rainy season and summer. However, under some special operating conditions, composite bearings can achieve a life better than that calculated by traditional methods, especially under light load conditions. These special operating conditions are that when the rolling surface (track and rolling element) is effectively separated by a smooth oil film and restricted pollutants, the appearance may be damaged. In fact, under ideal conditions, the so-called eternal composite bearing life is possible.
5、 The service life of composite bearing. The service life of rolling composite bearing is defined by the number of revolutions (or the working hours at a certain speed): the composite bearing within this service life shall have initial fatigue damage (peeling or defect) on any composite bearing ring or rolling body. But no matter in the laboratory experiment or in the theoretical application, it can be clearly seen that under the same working conditions, the appearance of the composite bearing is the same, and the theoretical life is very different. In addition, there are several kinds of composite bearing "life" with different definitions, one of which is the so-called "working life", which means that the theoretical life of a composite bearing that can be reached before it is damaged is caused by wear and damage, usually not fatigue, but wear, corrosion, seal damage and other causes.
