Embodiment 1

[0044] Embodiment 1, with reference to figure 1 , 2 As shown, the present invention provides a gear with a textured coating 2 , including a gear body 1 and a coating 2 attached to the gear body 1 . The coating 2 has good wear resistance and heat insulation performance, which is beneficial to reduce friction and increase the thermal deformation of the gear body 1 .

[0045] The surface of the gear body 1 is evenly distributed with a plurality of first micropits 3, through the texturing of the surface of the gear body 1, the microstructure of the surface of the gear body 1 can be changed, and the specific surface area of ​​the tooth surface of the base can be effectively increased, forming a coating 2 The coating provides a good adhesion surface and increases the adhesion between the coating 2 and the tooth surface of the substrate, thereby improving the anti-stripping and breakage of the coating 2. A plurality of textured regions are distributed on the surface of the coating ...

Embodiment 2

[0078] The gear with textured coating 2 provided by the embodiment of the present invention has the same realization principle and technical effect as that of embodiment 1. For a brief description, reference can be made to embodiment 1 for the parts not mentioned in this embodiment. Corresponding content.

[0079] refer to Figure 4 As shown, the textured region is a mixed micro-texture, the mixed micro-texture is selected from spherical cap and square texture, along the axial direction of the gear, a plurality of the second micro-pits 4 The textures of the second dimples 4 are the same, and the textures of two adjacent second micropits 4 are different along the circumferential direction. Optionally, other types of arrangement, such as the same texture along the axial direction of the gear, different textures along the circumferential direction of the gear, etc., can also be applied to the textured area.

Embodiment 3

[0081]The gear with textured coating 2 provided by the embodiment of the present invention has the same realization principle and technical effect as that of embodiment 1. For a brief description, the details not mentioned in this embodiment can be referred to in embodiment 1. Corresponding content.

[0082] refer to Figure 5 As shown, the textured region is a mixed micro-texture, the mixed micro-texture is selected from square and triangular textures, along the axial direction of the gear, the texture of a plurality of the second micropits 4 The textures of the two adjacent second micropits 4 are different along the circumferential direction. Optionally, other types of arrangement, such as the same texture along the axial direction of the gear, different textures along the circumferential direction of the gear, etc., can also be applied to the textured area.

Abstract

The invention provides a gear with a texturing coating, and relates to the technical field of mechanical transmission. The gear comprises a gear body and a coating adhering to the gear body, multiplefirst micro pits are uniformly distributed on the surface of the gear body, multiple texturing regions are distributed on the surface of the coating, and each texturing region comprises multiple second micro pits. The gear with the texturing coating is prepared by a processing method which comprises the steps that one, the first micro pits are processed on the gear to obtain a texturing gear; two,the surface of the texturing gear is coated with the coating to obtain a coating gear; three, the second micro pits are processed on the surface of the texturing coating gear to obtain a gear with atexturing coating. According to the gear with the texturing coating, the friction abrasion of the surface of the gear is reduced by part of the texturing coating, and the mechanical wear resisting performance and service life of the gear with the texturing coating are improved.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a gear with a textured coating. Background technique [0002] Gears are an extremely important basic part of high-end equipment, and are widely used in major equipment such as helicopters, wind power, tanks, high-speed rail, and ships. The performance of gear transmission often directly determines the operating performance, service life, safety and reliability of equipment. According to statistics, 80% of transmission mechanical equipment failures are caused by gear failures. Therefore, the development of high-performance gears such as low noise, long life, high power-to-weight ratio, high transmission precision, and high reliability has become an important scientific and technological issue in the development of related industrial fields in my country, and it is also an important issue in the research of transmission machinery in the field of mechanical engineer...
