Problems solved by technology
[0003] At present, gears generally need to be coated, that is, all surfaces on the gear body are provided with coatings, but when the gear meshes with the teeth, the meshing height will be reduced, and the rotational torque between the gear and the teeth will be considerably lost.
At the same time, when the gear and the gear are rotating, the meshing will not be smooth and the teeth will be skipped, which is the defect that the gear is provided with a coating.
If there is no coating on the gear body, the body is the original metal color, which not only affects the appearance, but also affects the service life of the gear

Embodiment Construction
[0018] Such as figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, the steps of a selective coating method for gears are as follows:
[0019] a. Divide the gear body 1 into: the first cylindrical surface 5, the second cylindrical surface 2, the first end surface 3 and the second end surface 4, the first cylindrical surface 5 has a plurality of ring-shaped arrangement of teeth, and the second cylindrical surface 2 There is a fitting end, and the fitting end is in the shape of a polygonal groove, which fits with the screw fitting, and the first end face 3 and the second end face 4 are located at both ends of the gear body 1;
[0020] b. Make a protective cover 6, the protective cover 6 is provided with a fitting part 7, the size of the protective cover 6 is to fit into and cover the first cylindrical surface 5, and the protective cover 6 is made of plastic or rubber material;
[0021] c. Put the protective cover 6 on the first cylindrical surface 5 to cover ...

The invention provides a method for selectively coating a gear. The method for selectively coating the gear meets the demands of gear coating, and also does not affect use function of the gear. The method for selectively coating the gear comprises the steps: 1 a gear body is divided into a first cylindrical surface, a second cylindrical surface, a first and a second end surfaces; 2 a protective sleeve is made, and is made from non-conducting materials; 3 the protective sleeve is sleeved on the first cylindrical surface, the first cylindrical surface is packed by the protective sleeve, and then the gear body is coated according to existing gear coating process; and 4 the protective sleeve is taken off after finishing coating process, and coatings are arranged on the second cylindrical surface, the first and the second end surfaces. The method for selectively coating the gear is simple in process and easy to operate.
Description
technical field [0001] The invention relates to a selective coating method for mechanical parts, in particular to a selective coating method for gears. Background technique [0002] There are many coatings on the surface of various mechanical parts. After the production is completed or during the production process, the mechanical parts are treated with black dyeing, nickel plating, chrome plating, tin plating, titanium plating, color electroplating, painting and coloring. The main purpose is to make the surface of the parts have different color coatings to achieve the effects of durability, beauty and identification of the parts. [0003] At present, gears generally need to be coated, that is, all surfaces on the gear body are provided with coatings, but when the gear meshes with the teeth, the meshing height will be reduced, and the rotational torque between the gear and the teeth will be considerably lost. . At the same time, when the gear and the gear are rotating, the...
