RESOURCE-SAVING TECHNOLOGY FOR INCREASING THE LIFE OF BALL BEARING FIXED JOINTS OF TRACTORS AND AUTOMOBILES

The article shows that the premature failure of a fixed assembly with a ball bearing in agricultural machinery is due to the elliptical shape of the outer ring of the bearing, which leads to an incorrect distribution of the force acting on it between the balls, which leads to a decrease in its service life. At the same time, the factors affecting the strength of a fixed assembly with a ball bearing when the diameter of the covering part is smaller than the diameter of the covered part (non-lubricated assembly) is lost using a press force are studied, and the main method of increasing the friction force is selected. The effect of using heating the covering part or cooling the covered part, applying a galvanic coating to the surfaces of the assembly and other methods is presented. However, due to the complexity of the proposed methods, the need for expensive equipment and the long recovery time, a simple, inexpensive, non-complex technology for increasing the friction coefficient, the technology of using anaerobic sealants, is presented.
