A special-shaped gear with an inner shaping layer and its processing technology

Abstract

The invention discloses a special-shaped gear with an internal shaping layer and its processing technology, belonging to the technical field of gear processing. A special-shaped gear with an internal shaping layer includes a special-shaped gear body, and a self-fitting gear is provided inside the special-shaped gear body. Tooth surface tube, self-fitting tooth surface tube includes a self-fitting tube and a reinforcing fixed tube, the outer end of the self-fitting tube is wrapped with a self-lubricating ring and a selectively permeable film layer, a selectively permeable film layer and a self-lubricating ring There are many small oil pockets between them. After the last process of traditional gear processing, a self-fitting tooth surface operation is added. A self-fitting tooth surface tube is added on the inner side of the gear, and the self-fitting tooth surface tube is used to fit tightly Protect the gear teeth on the surface of the gear teeth, reduce the wear of the gear teeth during transportation and movement, and ensure its precision. In addition, through the setting of the self-lubricating ring on the surface of the self-fitting tooth surface tube, the gears can be adjusted when using the gears. The surface of the teeth produces comprehensive lubrication, which eliminates the separate oiling steps in traditional installation operations.

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
