Problems solved by technology

After a long time of use, the life of high wear-resistant precision gears will be shortened, so the performance of high wear-resistant precision gears such as strength, durability, tensile resistance, hardness and surface smoothness can affect the use of high wear-resistant precision gears Life, especially when severe wear occurs in long-term use, the strength and other properties of the gear will decline to a certain extent. Therefore, how to obtain high strength, high durability, high tensile strength, high hardness and High wear-resistant precision gears with high surface smoothness is a research direction required by society

Abstract

The invention relates to a high-wear-resistant precision gear and a preparation method thereof, and belongs to the technical filed of track machinery. The high-wear-resistant precision gear is composed of a gear with a module of less than 0.2, the gear with the module of less than 0.2 is formed by a titanium dioxide composite silicon carbide ceramic metal structure with a volume ratio of more than70 %, and the titanium dioxide composite silicon carbide ceramic metal structure is composed of any one or more elements of Si, C, O, Fe, Al, Ti and Zn. The preparation method of the high-wear-resistant precision gear comprises the steps of (1) part preparing; (2) pre-cleaning; (3) part clamping; (4) charging; (5) vacuum glow ion nitriding; and (6) cooling with a furnace. According to the provided high-wear-resistant precision gear and the preparation method thereof, the preparation method is simple, and the prepared high-wear-resistant precision gear is high in strength, simple in preparation process, low in production cost, non-toxic and harmless in used raw materials, environment-friendly and pollution-free.

Description

technical field [0001] The invention relates to a high wear-resistant precision gear and a preparation method thereof, belonging to the technical field of track machinery. Background technique [0002] In the prior art, gear transmission is usually achieved by gears arranged on different shafts meshing with each other. The gear directly connected to the output shaft of the motor is usually called the driving wheel, and the gear meshing with the driving wheel is called the driven wheel. The driven wheel shaft The drive shaft of the center is the driven shaft. After a long time of use, the life of high wear-resistant precision gears will be shortened, so the performance of high wear-resistant precision gears such as strength, durability, tensile resistance, hardness and surface smoothness can affect the use of high wear-resistant precision gears Life, especially when severe wear occurs in long-term use, the strength and other properties of the gear will decline to a certain e...
