INCREASING THE WEAR RESISTANCE OF DIFFERENTIAL SHAFTS THROUGH THE APPLICATION OF DIAMOND BURNING TECHNOLOGY
Abstract
The trouble-free operation of any mechanism depends on the correct operation of its individual components and assemblies, timely maintenance and, if necessary, high-quality repairs. An analysis of the reasons for the failure of the working mechanism makes it possible to single out the wear of the contacting surfaces as the main cause. As a result of wear, technical gaps increase, unacceptable backlashes appear, and the tightness of seals is violated. Further operation of such components and assemblies is unacceptable. It follows from this that a decrease in wear of friction surfaces increases the durability of parts, assemblies, assemblies and ensures their trouble-free operation.The material of the article is devoted to the issue of increasing the wear resistance of surfaces of machine parts due to hardening methods of machining. One of the most loaded vehicle components, the differential, was chosen as the object of research. A common cause of differential failure is the wear of the shaft journals at the points of contact with the lip seals. The article focuses on the use of diamond smoothing of the sections of the differential shafts that are more prone to wear. The advantages of the proposed method of machining are the sufficient simplicity of the hardening operation, low cost and the possibility of obtaining abrasion-resistant surface.
