Special-shaped gear with inner shaping layer and machining process thereof

Abstract

The invention discloses a special-shaped gear with an inner shaping layer and a machining process thereof, and belongs to the technical field of gear machining. The special-shaped gear with the innershaping layer comprises a special-shaped gear body, wherein a self-fitting tooth surface pipe is arranged on the inner side of the special-shaped gear body, the self-fitting tooth surface pipe comprises a self-fitting barrel and a reinforcing fixing barrel, the outer end of the self-fitting barrel is wrapped with a self-lubricating ring and a selective permeable membrane layer, and a plurality oftiny oil bags are arranged between the selective permeable membrane layer and the self-lubricating ring. The self-fitting tooth surface operation is additionally arranged after the last working procedure of traditional gear machining, the self-fitting tooth surface pipe is additionally arranged on the inner side of the gear, the self-fitting tooth surface pipe is tightly attached to the surfaces of gear teeth to protect the gear teeth, and the abrasion on the gear teeth during the transporting and moving process is reduced, so that the precision degree of the gear is ensured, and in addition,the self-lubricating ring is arranged on the surface of the self-fitting tooth surface pipe, so that the comprehensive lubricating effect can be generated on the surfaces of the gear teeth when the gear is used, and the operation step of independent oiling in the traditional mounting operation is abandoned.

Description

technical field [0001] The invention relates to the technical field of gear processing, and more specifically relates to a special-shaped gear with an inner shaping layer and a processing technology thereof. Background technique [0002] With the clamor of social environment and public nuisance control, the requirements for low noise of automobiles are becoming stronger and stronger. However, with the rapid development of electric vehicles, the vibration and noise of transmissions are particularly prominent, and the market complains seriously. First of all, noise is harmful to the human body. People's health will be damaged to varying degrees in living, studying and working. Studies have shown that steady-state and unsteady-state noises have different effects on people, and the most unfavorable to people is the unsteady-state noise. At the same time, with the rapid development of the automobile industry, the agglomeration of car ownership in society has increased, so the no...

Problems solved by technology

[0005] After the existing gears are processed, there is often no protection device on the gears. Many gears are stacked together, and they are easy to collide with each other during transportation and transfer, and gears of different models are easy to be stuck together by force, that is, the pinion is stuck. The inner side of the large gear is easy to damage the teeth of the large gear during transportation, which will affect the precision of the gear
