Problems solved by technology

The heat treatment of super large bearing parts plays a very important role in bearing manufacturing. Because the effective thickness of super large bearings is too large, it far exceeds the hardenability of the material. At the same time, because large bearing rings release a lot of heat during quenching and take a long time , so that the local oil temperature rises faster. The conventional quenching cooling method adopts the method of serial cooling through the crane through the crane. Becaus

Abstract

The invention relates to a bearing propelled stirring quenching device comprising a quenching oil tank, three oil propellers with a same structure, and three fluid directors with a same structure. The three oil propellers are arranged at the quenching oil tank with same distances along a circumferential direction. The three fluid directors are arranged at the bottom of the quenching oil tank with same distances along a circumferential direction. Directing tubes of the three fluid directors are arranged along a circumferential direction, and are arranged with a 30 DEG elevation angle upward. The oil propellers are assembled by using parts of oil transmission tubes, propeller shafts, propeller blades, cylindrical joints, punched bends, and the like. Oil inlet holes on the upper parts of the oil transmission tubes of the three oil propellers are respectively connected with oil outlet holes on the quenching oil tank through pipelines. Punched bends of the three oil propellers are respectively connected with connection bends of the three fluid directors through three bend through holes at the lower part of the quenching oil tank. With the device provided by the invention, large bearing quenching hardness and hardness uniformity are improved, and bearing quality and bearing service life are improved.

Description

technical field [0001] The invention relates to a bearing quenching device, in particular to a quenching device for extra-large stainless steel bearings. Background technique [0002] Heat treatment is to heat the corresponding metal material to a certain temperature and hold it for a certain period of time and then cool it rapidly to change the internal structure of the metal material and enhance the mechanical properties of the metal material. The heat treatment of super large bearing parts plays a very important role in bearing manufacturing. Because the effective thickness of super large bearings is too large, it far exceeds the hardenability of the material. At the same time, because large bearing rings release a lot of heat during quenching and take a long time , so that the local oil temperature rises faster. The conventional quenching cooling method adopts the method of serial cooling through the crane through the crane. Because the workpiece is too large, the serial...
