Slewing bearing raceway and gear induction hardening equipment




1.Parts requirements

1)Quenching part: continuous scanning quenching of the inner and outer raceways of the bearing, single tooth induction hardening of the teeth.

2)Technical specifications of hardened parts.

Maximum diameter range:300-5000mm。

Maximum part height:400mm。

Weight of hardened part:5000Kg。

2.Process plan

1)According to the requirements of slewing bearing induction hardening technology, the structure of the transformer lifting movement, radial feed and lateral movement is adopted. The turntable is driven by a servo motor to rotate, which can realize the functions of automatic gear indexing and automatic gear indexing. Continuous raceway scan hardening. The machine tool has better versatility.

2)The main machine adopts a gantry structure, and a horizontal slide table is arranged on the beam to realize the radial movement of the sensor. The moving beam is designed with the lifting and lateral movement of the sensor, which can realize the lifting and lateral movement of the sensor. The induction heating load is designed to be mounted on a lateral moving slide.

3)Transformer / inductor is driven by servo motor, ball screw and servo motor. The moving guide is linear and can precisely control the moving position.

4)The induction heating power supply uses 200Kw / 4-10khz parallel resonant full digital IGBT transistor power supply, and is equipped with a set of induction heating loads, which can be used with inductors of different structures. Through load matching and adjustment, the best heating effect can be achieved.
