The invention relates to a device for tooth-by-tooth heating of a herringbone gear, which includes a heating device, a rotating platform device, an induction device, a driving device, a working platform, a power supply, a motor, a driving sleeve and a plurality of infrared temperature measuring cameras, The heating device includes a tooth-like induction coil and an induction coil support. The induction coil support is connected with the drive sleeve, insulating gasket and the tooth-like induction coil. The rotating device platform fixes and rotates the herringbone gear, and the driving device drives the drive sleeve to perform The herringbone movement realizes the heating of the imitation tooth-shaped induction coil in the tooth root; the induction device senses the light signal, and uses the detection circuit to control the motor to make the herringbone gear rotate, and the power supply and the motor are fixed on the working platform. The present invention also provides a heating method using the above-mentioned heating device, which effectively solves the problem of inability to heat the dedendum of the herringbone gear, improves the hardness of the dedendum and the tooth surface, and improves the service life of the herringbone gear.
Description
technical field [0001] The invention belongs to the technical field of heat treatment, and in particular relates to a device and a heating method for tooth-by-tooth heating of a herringbone gear. Background technique [0002] Electromagnetic induction hardening is one of the most important heat treatment processes nowadays. Its principle is that induction current quenches the tooth root and surface of each workpiece. After heating and cooling, the martensitic structure will obtain higher hardness. The internal structure still has good toughness, plasticity and high strength. The induction heating technology has the characteristics of fast, clean, energy-saving, easy to realize automation and online production, and high production efficiency. High power density, can work in various environments, has low loss, does not produce any physical pollution, and is also one of the green and environmentally friendly heating processes. With the development of industry, the requirements...
