Tool for bearing ring made of high-temperature carburizing bearing steel and control method based on heat treatment deformation of tool

Abstract

The invention discloses a bearing ring tool made of high-temperature carburizing bearing steel and a control method based on heat treatment deformation of the bearing ring tool, and relates to the technical field of bearing machining. The invention aims to solve the problems that the existing high-temperature carburizing bearing steel with larger diameter and wall thickness has larger deformation after carburizing, the shape correction is unstable during mechanical shape correction treatment, and the quenching and tempering interval is too long to cause part cracking. The high-temperature carburizing bearing ring is composed of an annular structure and an annular protrusion, the outer diameter of the annular structure is the same as the size of the high-temperature carburizing bearing steel bearing ring, and the height of the annular structure is 10 mm; an upward annular protrusion is arranged at the position of an inner ring of the annular structure, and the height of the annular protrusion is 3 mm. The outer side of the annular protrusion is attached to the inner side of the high-temperature carburizing bearing steel bearing ring. The control method comprises the steps of parameter selection; mounting a tool; heat treatment; and surface treatment. The method is used for bearing ring heat treatment.
