4 assembly points of jaw crusher eccentric shaft and bearing

The eccentric shaft and bearing are important parts of the jaw crusher and play a very important role in the jaw crusher. Therefore, the installation of the eccentric shaft and the bearing requires special attention. The following is a description of the eccentric shaft and bearing installation. 4 points:

Before installing the bearing, it is necessary to do the research and development of the bearing and put it into the bearing housing. Use the level to check the placement level and coaxiality of the bearing. After the test is passed, install the eccentric shaft on the bearing. The red shaft powder can be applied to detect the cooperation between the shaft and the bearing.

Bearings need to use the principle of thermal expansion and contraction during the installation process, so strict space heating process is required, and bearings of different sizes and specifications are heated at a suitable temperature. Uneven heating of the bearing will cause the quality of the assembly to decrease, so ensure that the bearing is heated evenly.

During the installation, the opposite corner of the bearing is struck to ensure that the bearing enters the eccentric shaft in a balanced manner. When the eccentric shaft enters the moving shaft, the hammer is required to hit the moving jaw, and the interaction force is used to make the eccentric shaft enter the moving balance in a balanced manner. Does not damage the bearing.

The grease is injected into the moving boring so that the grease in the bearing accounts for about 50% of the space volume, and the grease needs to be replaced once every 3-6 months. The roller bearing of the roller bearing should be cleaned with clean kerosene or gasoline to make the bearing fully and evenly lubricated, prolong the service life of the bearing, apply lubricating oil between the bearing and the bearing seat, reduce bearing wear, eccentric shaft and machine The contact area of ​​the frame should be greater than 80% and the gap should be less than 0.07mm.

The above introduces the eccentric shaft of the jaw crusher and the four assembly points that need to be paid attention to during the installation of the bearing. The eccentric shaft and the bearing are the key components of the crusher operation. Therefore, special attention should be paid to the above during the installation process of the jaw crusher. 4 o'clock, to ensure that the crusher is properly installed and operating normally.
