AI Technical Summary

Problems solved by technology

Ordinary gears only have external gears, which rely on external gears and other transmission parts to move. During the movement, heat will be generated, resulting in gear wear and shortened service life, and the transmission function of the external gear on the gear body is single.

Abstract

The invention discloses an abrasion preventing gear. A gear body and a gear face are included; the center of the gear body is provided with a shaft hole which is embedded in the gear face; a pluralityof through holes are formed around the gear face; the outer side surface of the gear body is provided with a plurality of conical teeth which are provided with a protective layer; the protective layer is composed of the following components, by weight, 5.3 parts of epoxy resin, 1.4 parts of hydroxyethyl cellulose, 0.7 part of barium petroleum sulfonate, 1.2 parts of talcum powder, 0.6 part of glyceryl monostearate and 0.3 part of vinyl trimethoxy silane. The abrasion preventing gear is simple in structure and has the beneficial effects that abrasion is reduced, transmission is more flexible,corrosion resistance is achieved, and the service life is long.

Description

technical field [0001] The invention relates to a gear, in particular to an anti-wear gear. Background technique [0002] Gears have a wide range of uses and are important parts in various mechanical equipment, such as machine tools, airplanes, ships, and watches and fans used in daily life. All kinds of gears are used. There are many types of gears, such as cylindrical spur gears, cylindrical helical gears, helical gears, straight bevel gears, spiral bevel gears, worm gears, etc. Gears are toothed mechanical parts that can mesh with each other, and they are widely used in mechanical transmission and the entire mechanical field. Modern gear technology has reached: gear modulus 0.004 ~ 100 mm; gear diameter from 1 mm to 150 meters; transmission power up to 100,000 kilowatts; speed up to hundreds of thousands of rpm; the highest peripheral speed up to 300 m / s. The application of gears in transmission has appeared very early. More than three hundred years ago, the ancient G...
