Installation method of jaw crusher bearing

2020-03-25

The jaw crusher is widely used in mining, smelting, building materials, highway, railway, water conservancy and chemical industries, and is suitable for coarse, moderate and fine crushing of various ores and large materials. Bearing is one of the more important parts in jaw crusher. Reasonable and correct installation is conducive to the efficient and stable operation of the equipment. The following is the main point of jaw crusher bearing installation.
First, the bearing is checked for rust before installation
 
If the bearing is corroded, it should be cleaned with diesel or kerosene first, and then the radial clearance of the bearing, the size and accuracy of the bore, and the size of the eccentric shaft assembly journal should be checked.
 
Second, the bearing is heated by hot charging
 
Due to the large amount of bearing journal bearing (to the maximum capacity that can be accommodated or withstood), it is difficult to fit into the journal by ordinary press-fitting methods. It is necessary to use the hot-loading method to heat the bearing to a temperature of about 100 ° C. Only after the shaft hole expands to the size of the journal, can the assembly be performed.
 
Third, ensure that the bearing installation is accurate and in place
 
In order to ensure that the bearing installation is in place, the oil seal, end cover and retaining ring of the bearing are installed in advance at the shaft end of the lifting end, and then the external bearing is installed. At this point, the end cover and bearing are installed in place.
 
Fourth, do a good job of inspection after installation
 
Henan Hongxing reminds the user to wait for the bearing to cool down completely after assembly, and then check the radial clearance of the bearing with a feeler gauge. If the clearance is too small or there is no clearance, you must find the cause in time. If you cannot find it, you must remove and reassemble; If the clearance is appropriate, you can apply grease and then assemble the other parts.
 
The above is the installation method of the jaw crusher bearing. The advantages of the installation method are: easy removal, which can improve the operating efficiency and reduce the maintenance time; it is safer to remove the flywheel as a whole; Bearings are important parts of jaw crushers, and it is very important to install them properly and regularly.
