Half body gear dedicated sling

Abstract

The invention relates to a semi-gear special sling used in the mechanical element heat treatment technique, comprising a main beam, an auxiliary beam, an adjuster, a adjust rod, a adjust sheath, a compression spring, bearing, a adjust axle, a hook, and a hook chain. The adjustor of main beam is formed by mounting the long axle, round nut, baffle plate on the middle-upper part of adjustor; mounting the adjust rod, bearing, compression spring and adjust sheath on the upper part of adjustor while fixing them with long bolt, nut and baffle plate; mounting the adjust axle in the hole of central beam of adjustor which is fixed by slotted nut and slotted bolt; each one end of four hook chains is mounted on the main and auxiliary beams, and after mounting the adjustor of main beam on the main beam, adjusting the compression spring of adjust sheath, to move upwards the main beam adjustor under the elastic force of compression spring, until the adjust axle in the center of beam hole. The invention can meet the demand of large-scale gear including littler quench distortion, uniform rigidity, better safety, and higher producing efficiency.

Description

Technical field: [0001] The invention relates to a special spreader for half gears in the technical field of heat treatment of mechanical parts. Background technique: [0002] At present, the quenching of large half-body gears with a diameter of more than 5 meters usually adopts heat treatment processes such as overall quenching, induction hardening, and flame quenching. There is no special lifting tool for the half-body gear, and the chain is used to lift the gear up and then hang it down for quenching. The deformation is difficult to control, the safety is poor, and the furnace loading capacity is small, which is not suitable for mass production. Can not fully meet the practical application requirements of the half gear. Therefore developing a special spreader for half-body gears has always been a new subject to be solved urgently in China. [0003] The purpose of the present invention is to provide a kind of scientific conception, easy manufacturing process, quenching w...

Problems solved by technology

[0003] The purpose of the present invention is to provide a kind of scientific conception, easy manufacturing process, quenching with a special spreader for half-body gears, easy operation and flexible control of the entire quenching process, which can better meet the requirements of the gear quenching process, and improve product quality and hardness. The distribution is relatively gentle, which overcomes the shortcomings of uneven hardness, large deformation, and small furnace loading caused by the original quenching method, and makes the overall performance of the parts reach a higher level. It is widely used in the technical field of heat treatment of such parts. A special spreader for half gear
