WAYS TO INCREASE THE STRENGTH OF THE SURFACE OF THE PARTS

This article presents the results of a study conducted to develop a technology for increasing the service life of the shaft-gear teeth obtained by casting in the electric school recycling shop used at the Central mechanical repair plant of Almalyk KMK. In particular, the existing methods of increasing the rigidity and wear resistance of the gear surface of the teeth and the developed mode of heat treatment are presented. The diagram of the device used for heat treatment, and the indications for changing the flow rate are given in the form of a table. As a result of the research, a new method of heat treatment was developed to improve the wear resistance and service life of the product obtained by casting in the electric school remelting shops. At the end of the article, we recommend heat treatment modes for increasing the service life of injection molding products obtained on the basis of repeated dissolution of the electric school.
