A cautious, erection and dismantling
According to the different application and SKF bearing size and type, choose appropriate installation method (mechanical or hydraulic pressure) and tools. Here are some of the basic installation SKF bearing principle:
1. Do not put in the rolling element installed power, it is easy to cause the rolling element and a circle of the interface partial overload, leading to premature failure of SKF bearing.
2. Don't use any hard tools (such as a hammer and screwdriver, etc) in SKF bearing surface directly knock, it will lead to a SKF ring bearings or breaking fracture.
Second, clean
SKF bearing to clean is very important. SKF bearing surface and rolling element turning ring the surface roughness of the μ m usually of 1/10, so smooth surface damage of pollutants is very sensitive. Rotating between surfaces and lubricant layer are generally 0.2 ~ 1 μ m, more than the impurity particles size lubricant type will be rolling element of excessive rolling in spherical roller bearing steel produced in partial pressure, will eventually result in permanent material fatigue.
In addition to this, the outside environment of dust particle size can reach up to 10 μ m, will damage the heart roller bearings. Therefore, the clean environment clean to the storage and installation SKF bearing is very important.
Three, process detection
The use of thermal can supervise the working temperature of SKF bearing, and realize the temperature more than e. automatic alarm or stop when to prevent burning shaft accidents. With high temperature often said bearing is already in the abnormal situation. High temperature is bad for SKF bearing lubricant. Sometimes SKF bearing to the bearing can be overheating in the lubricant. In more than 125 ℃ if bearing temperature even reduce long-term transfer SKF bearing life. The reason caused by high temperature bearings include: lubrication is insufficient or too lubrication, lubricant. Contains impurities, load is too large, cylindrical roller bearing loss loop, the gap is insufficient, and oil seal of high friction produced.
