Abstract
The invention relates to a forging method of a reverse gear idler, in particular to a high-precision and high-strength reverse gear idler and a forging method thereof. According to the high-precision and high-strength reverse gear idler and the forging method thereof, the technical problems that in the prior art, a reverse gear idler is poor in strength and lack of positioning, and the precision in machining is poor, so that assembly is poor, and transmission efficiency is low are solved. A steel billet material is put into a circular sawing machine to be sawed and sent to a heating furnace to be heated; then a steel billet is sent to a punching machine to be punched and then put into an annealing furnace to be subjected to annealing, spheroidizing annealing and isothermal annealing; a reverse gear idler rough piece is subjected to sand blasting and phosphorus saponification treatment; then reverse tapered teeth of the reverse gear idler rough piece are finished, and a reverse gear idler finish piece is obtained; and then the reverse gear idler finish piece is subjected to carburizing and quenching as well as stress relieving and cooled in nitrogen, the reverse gear idler finish piece is heated and subjected to carbonitriding and quenching stress relieving and put into hot oil to be cooled, and finally a finished product of the high-precision and high-strength reverse gear idler is obtained.
Description
technical field [0001] The invention relates to a forging method of a reverse gear idler, in particular to a high-precision and high-strength reverse gear idler and a forging method thereof. Background technique [0002] As a necessary speed change device for a car, the transmission can generate different gear ratios between the engine and the wheels during the running of the car, and the engine can work at its best power performance state by shifting gears. There are multiple sets of gears in the transmission housing to transmit different speed ratios, but when the car needs to go backwards, only changing the speed ratio can not achieve the purpose of the car going backwards, so there is also a reverse gear idler in the transmission housing, the reverse gear idler The wheel is the transmission gear in the middle of two transmission gears that are not in contact with each other. It meshes with these two gears at the same time, and is used to change the rotation direction of ...
