Bearing raceway and gear induction hardening equipment

1 Quenched parts requirements

1) Hardening part: continuous scanning hardening of the inner and outer raceways of the bearing, and single-tooth induction hardening of the tooth.

2) Technical specifications of quenched parts.

The maximum diameter range of quenched parts: 300-5000mm.

Maximum quenched part height: 400mm.

Maximum hardened part weight: 5000Kg.

2 Induction hardening equipment process plan

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

2) The main machine adopts a gantry structure, with a horizontal sliding table on the beam, which can 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 installed on a horizontally movable sliding table.

3) The transformer/inductor is driven by a servo motor, a ball screw, and a servo motor. The moving guide is linear, and the moving position can be precisely controlled.

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