Inner hole quenching inductor for dual-conical-surface bearing sleeve ring

Abstract

The invention discloses an inner hole quenching inductor for a dual-conical-surface bearing sleeve ring. The inner hole quenching inductor comprises a quenching transformer, a bus bar and a water spray box, wherein the front end of the bus bar is connected with the quenching transformer; the water spray box is fixedly fixed at the tail end of the bus bar; an upper arc-shaped effective ring and a lower arc-shaped effective ring are arranged at the tail end of the bus bar; magnetizers are arranged on the upper arc-shaped effective ring and the lower arc-shaped effective ring; and the upper arc-shaped effective ring and the lower arc-shaped effective ring are separately used for heating upper and lower conical surfaces of the bearing inner ring. The inner hole quenching inductor adopts two fan-shaped inductors which are arranged up and down to complete quenching of upper and lower conical surfaces of the bearing inner ring once, so that the process is simplified, the production cost is reduced, and quenching quality is guaranteed.

Description

technical field [0001] The invention belongs to the field of quenching of inner rings of bearings, in particular to a quenching inductor for inner holes of double-cone bearing rings. Background technique [0002] The existing quenching methods for the inner ring of the bearing are as follows: figure 1 As shown, the process: 1) Firstly, the inductor 9 is used to quench the upper cone surface of the bearing inner ring 7; 2) The bearing is clamped twice, and then the inductor is used to quench the lower cone surface of the bearing inner ring. Defects of existing sensors: 1) The part needs to be clamped twice; 2) Two sets of tooling are required; 3) The part needs to be turned 180°, which makes it difficult to realize the mechanical action; 4) The second cone surface quenching is easy to match the first The sub-quenching zone causes tempering. Contents of the invention [0003] The invention provides a quenching inductor for the inner hole of the double-cone bearing ring, wh...
