Rust-proof gear

Abstract

The invention discloses an anti-rust gear, which comprises a gear main body. The gear main body is provided with external teeth, and an external tooth groove is arranged between the external teeth and the external teeth. An oil injection hole is provided inside, and an oil groove is arranged inside the inner hole of the main body of the gear, and the oil injection hole communicates with the oil groove. There is nylon filler, and the outer surface of the gear body is provided with a protective layer, the protective layer is a sulfide layer, and the thickness of the sulfide layer is 3-6mm. The invention effectively softens the hardness of the gear surface by increasing the structure of vulcanized material on the working surface of the gear, increases the lubrication between the meshing gears, improves friction, reduces wear, and thus prolongs the service life of the gear.

Description

technical field [0001] The invention belongs to the field of electric tool auxiliary equipment, and in particular relates to an antirust gear. Background technique [0002] There are teeth on the rim that can continuously mesh with mechanical elements that transmit motion and power. Gears are toothed mechanical parts that can mesh with each other, and the application of gears in transmission has appeared very early. At the end of the 19th century, the principle of generative gear cutting method and special machine tools and cutting tools using this principle appeared one after another. With the development of production, the stability of gear operation was paid more attention. However, if the gear is not used for a long time, the inner hole and the shaft will rust, which will lead to problems such as a decrease in work efficiency. [0003] Gears are common mechanical transmission components. During the transmission process, noise and vibration are generated due to the comb...

AI Technical Summary

Problems solved by technology

However, if the gear is not used for a long time, the inner hole and the shaft will be rusted, resulting in a decrease in work efficiency and other problems.

[0003] Gears are common mechanical transmission components. During the transmission process, noise and vibration are generated due to the combined effects of various factors. In order to further eliminate noise, the commonly used methods are to optimize gear design parameters, optimize gears, or improve gear manufacturing. process, improve the machining accuracy of gears, and reduce installation errors; but it is difficult to improve, and at the same time increases the design and manufacturing costs

[0004] At the same time, common gears are made of carbon steel or alloy steel. After heat treatment, the gear teeth are quenched, and surface strengthening treatments such as liquid nitrogen or laser treatment are used to improve the hardness of the gear surface. The hardness of the asperity also increases accordingly, so that it takes a long time for the gears to enter normal wear when meshing, which consumes a lot of energy, and after the asperity is worn, it will fall into the lubricating oil and be brought into the meshing gap by the driven gear. Participate in gear wear, which intensifies the wear of the gear surface, thereby shortening the service life of the gear
