Integral gear quenching equipment and process thereof

Abstract

The invention discloses integral gear quenching equipment and a process thereof. The integral gear quenching equipment comprises a base and a gear positioning device, wherein the gear positioning device is located on the base and is used for fixing a gear, gear quenching equipment is arranged above the gear positioning device, the gear quenching equipment comprises a longitudinal adjustment fixedseat, a heating device and an oil spraying and cooling device which are arranged on the longitudinal adjustment fixed seat and are matched with a tooth groove of the gear, the heating device and the oil spraying and cooling device are connected with a gear monitoring system which is used for monitoring the gear processing state in real time by virtue of a controller, the gear is fixed to a platform on the base by the gear positioning device, and the position and the precision of the heating device and the oil spraying and cooling device are controlled by the controller according to quenching depth requirements so as to integrally quench the load surface of the gear. The gear quenching equipment has the advantages of integrality in quenching and simple method, the product quality and yieldare obviously increased, and processed gear teeth have the advantages of high strength, good wear resistance, long service life and high bearing capacity.

Description

technical field [0001] The invention relates to the field of gear quenching, in particular to an integral gear quenching device and a process thereof. Background technique [0002] As we all know, gears are key components in mechanical equipment, and they are widely used in industrial fields such as automobiles, airplanes, tanks, and ships. It has the advantages of accurate transmission, compact structure and long service life. Gear transmission is the most common mechanical vibration in modern machines, an important form of transmitting mechanical power and motion, and an important basic part of mechanical products. Compared with belt, chain, friction, hydraulic and other machinery, it has a series of advantages such as large power range, high transmission efficiency, high peripheral speed, accurate transmission ratio, long service life, and small size and structure. Therefore, it has become an indispensable transmission part for many mechanical products, and it is also t...

Problems solved by technology

[0007] The tooth side of the gear is a heavy-duty surface, and the other side is rarely heavy-loaded when it is reversed. In addition, after the gear is installed in one direction, it is rarely installed in the opposite direction. It belongs to the light-loaded surface. The existing processing methods do not care Both the heavy-loaded surface and the light-loaded surface are heated and quenched together. Although the quenching process requirements are met, the quality of the gear is reduced. The heavy-loaded surface of the sawtooth is more likely to be worn in subsequent processing operations. shortened service life

[0008] Patent No. CN201210243890.X discloses a process method for quenching slewing bearing gears. The invention is based on the coupling gap between the intermediate frequency inductor and the tooth groove, the depth of current penetration, the linear velocity of the tooth groove, the temperature and concentration of the quenching liquid, etc. The setting and adjustment of process parameters improves the quenching quality, but this invention quenches all the teeth of the gear, which affects the life of the gear to a certain extent
