Embodiment
[0064] A dual-frequency automatic induction heating method for spiral bevel gear 5, comprising the following steps:
[0065] S1. Initially, the spiral bevel gear 5, the first disk-shaped induction heating coil 6 and the second disk-shaped induction heating coil 10 are uniformly distributed at 120° above the support turntable 3, and the computer 15 controls the first motor 14 to drive the stepped shaft 2 Reverse 120° counterclockwise, so that the spiral bevel gear 5 reaches directly below the first disc-shaped induction heating coil 6; the computer 15 controls the rotation of the second motor 16 of the screw lifting device to drive the sleeve jacking frame 21 to move upward, and then Drive the support turntable 3 to move upward along the stepped shaft 2, so that the spiral bevel gear 5 is embedded in the first disk-shaped induction heating coil 6; the computer 15 controls the first disk-shaped induction heating coil 6 to perform intermediate frequency induction heating on the sp...

The invention discloses a double-frequency automatic induction heating device and method for a spiral bevel gear, and belongs to the technical field of heat treatment. The double-frequency automatic induction heating device for the spiral bevel gear comprises a supporting platform, a first induction heating device, a second induction heating device and a computer, the supporting platform is provided with a stepped shaft and a lead screw lifting device, the lower portion of the stepped shaft is connected with a first motor, an infrared temperature measuring device is arranged at the top of the stepped shaft, and the stepped shaft is sleeved with a supporting rotary disc; and the spiral bevel gear is placed above the supporting rotary disc, the lead screw lifting device is located below the supporting rotary disc, and the computer is connected with the first induction heating device, the second induction heating device, the first motor, the lead screw lifting device and the infrared temperature measuring device. According to the double-frequency automatic induction heating device and method for the spiral bevel gear, the induction heating process is automatically controlled based on the computer control and infrared temperature measurement technology, precise heating is achieved, and the tooth crest, the tooth profile and the tooth root of the spiral bevel gear are hardened at the same time.
Description
technical field [0001] The invention relates to the technical field of heat treatment, in particular to a dual-frequency automatic induction heating device and method for spiral bevel gears. Background technique [0002] As an important part in the mechanical transmission process, spiral bevel gears are widely used in aerospace, metallurgical equipment, ships, etc. Industry and many other industries, and the contact fatigue strength and wear resistance of its surface affect the normal service and working life. A large part of the failure of the spiral bevel gear pair is caused by fatigue failure, so improving the tooth surface strength, wear resistance and reducing stress concentration will help improve the quality and service life of the gear. The use of electromagnetic induction technology to heat the surface of the spiral bevel gear has the characteristics of fast, high efficiency and energy saving. However, due to the complexity of the tooth surface of the spiral bevel ...
