Abstract

The invention relates to the technical field of metal machining processes, and particularly relates to a production process for prolonging the service life of a speed reducer gear. The production process specifically comprises the following steps that (1) 17CrNiMo6 steel is selected as a gear raw material; (2) the raw material is placed in a heating furnace for three-section heating; (3) after being cooled, the raw material is placed in treatment liquid to be soaked; and (4) the raw material is forged into the gear. Stress in the 17CrNiMo6 steel is fully released through three-section heating,so that the service life of the gear machined subsequently is prolonged; and the raw material subjected to three-section heating is treated through the treatment liquid, so that heavy metal ions canbe reduced, and the wear resistance of the raw material is improved. Experiments show that the service life of the speed reducer gear produced through the production process is prolonged by 15% to 20%.

Description

technical field [0001] The invention relates to the technical field of metal processing technology, in particular to a production technology for improving the service life of gears of reducers. Background technique [0002] The reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid shell. It is often used as a reduction transmission device between the prime mover and the working machine. Mechanisms play the role of matching speed and transmitting torque, and are widely used in modern machinery. [0003] Chinese patent (notification number: CN105983843A, announcement date: 2016.10.05) discloses a gear processing technology for reducers. The processing technology includes the following steps: (1) material selection: the selected grade is 20CrMnMo; (2) furnace heating; (3) ) Forging: Upsetting and drawing twice on the die forging machine; (4) Normalizing treatment: Normalizing temperature 850-950°C; ...
