Gear synchronous quenching device

Abstract

The invention discloses a gear synchronous quenching device. The device comprises a quenching power supply extension machine, an annular sensor and a clamping tooling used for clamping to-be-quenchedgears. The annular sensor is fixed to the quenching power supply extension machine and connected with a quenching power supply extension machine output power supply. A lifting mechanism is arranged atthe lower end of the quenching power supply extension machine. An annular water pouring ring is arranged at the lower end of the annular sensor and fixed to the outer wall of the quenching power supply extension machine. A plurality of water pouring nozzles are formed in the inner wall of the annular water pouring ring. The clamping tooling comprises a rotating turntable and self-rotating toolingbodies uniformly arranged on the rotating turntable along a rotating turntable rotary shaft. The to-be-measured gears are mounted on the self-rotating tooling bodies correspondingly and driven by theself-rotating tooling bodies to rotate. The to-be-measured gears are heated uniformly through heating of the annular sensor, residual stress produced due to non-uniform heating of the to-be-measuredgears is prevented, meanwhile, the to-be-measured gears are quenched by means of the annular water pouring ring, quenching can be performed in time, deformation produced because of the long time duration between part heating and quenching, and the gear synchronous quenching device is simple in structure and can be used for greatly improving the gear quenching efficiency.

Description

technical field [0001] The invention belongs to the technical field of induction heating, in particular to a gear synchronous quenching device. Background technique [0002] Gear is a widely used transmission part. The working mode of intermeshing for transmission requires the gear to have the characteristics of shock resistance, vibration and noise as small as possible, high strength, good wear resistance and long life. Therefore, in the production process of gears, the surface profile of gears needs to be heat treated to improve its strength and wear resistance. The traditional quenching method is quenching in a carburizing furnace, but due to the long interval between heating and quenching, it often causes large deformation of the workpiece and affects the transmission efficiency of the gear. In addition, the traditional method has high energy consumption, high cost and low efficiency. This treatment method also tends to increase residual stress on the root tooth surfac...

Problems solved by technology

The traditional quenching method is quenching in a carburizing furnace, but due to the long interval between heating and quenching, it often causes large deformation of the workpiece and affects the transmission efficiency of the gear

Moreover, the traditional method consumes a lot of energy and costs high, and the efficiency is low

This treatment method is also easy to increase the residual stress on the root tooth surface, resulting in the occurrence of fracture, so it cannot achieve a satisfactory treatment effect
