It is often the case that some friends use improper methods when installing SKF bearings, resulting in damage to the SKF bearings during installation. Today I will tell you about the preparations for the installation of the SKF bearing on the lathe. I hope everyone has to help.
For the correct installation method of SKF bearings, please refer to the article "Introduction to the installation method of SKF bearings".
1. Selection and requirements for the installation site
The installation site should be at a distance from the lathe, grinder and other mechanical equipment. The site should be cleaned and kept dry and clean to prevent iron filings, sand, dust and moisture from entering the bearing.
2. Check the bearing model and prepare the installation tool
Verify that the bearing type and size meet the installation requirements, and select the appropriate assembly method according to the structural characteristics of the bearing and the various components that match it, and prepare the tools and gauges for installation. Commonly used installation tools include hand hammers, copper rods, sleeves, special pads, screw-mosquito fixtures, presses, etc., with vernier calipers, micrometers, dial gauges, etc.
3. Verify the bearing assembly surface
The surface of the bearing assembly and the surface of the part with which it is fitted, if there is a bump, rust layer, wear debris, sand, dust and dirt, one bearing is difficult to install, resulting in incorrect assembly position; second, these attachments form abrasive, easy Abrasive damage to the working surface of the bearing, affecting the quality of the assembly. Therefore, the surface of the journal, the surface of the housing hole, the end surface of the shoulder, and the mating surfaces of the connecting parts such as bushings, washers, end caps, etc., should be carefully inspected before installation. If there is a rust layer, it can be finely smashed, and the fine sand cloth is used to illuminate, and at the same time, the attachment surface of the bearing assembly and the attached parts thereof are also removed.
