Solid Lubricating Coating Apparatus for Gear Tooth Surfaces

Abstract

The invention relates to the technical field of part film coating devices, in particular to a coating device of a solid lubricating coating for a tooth surface of a gear. The coating device of the solid lubricating coating for the tooth surface of the gear comprises a heating furnace, a gas storing tank, a control system, a tail gas treating assembly and at least one reactor assembly; all the reactor assemblies are arranged in the heating furnace; a reaction cavity is formed in each reactor assembly, and is a closed space relative to the heating furnace; and the control system is used for controlling running of the heating furnace. During machining, the gear performs film coating machining in the closed space of each reaction cavity, the space for gas to react and produce solids is remarkably reduced, the reaction gas can be uniformly distributed in the closed space of each reaction cavity more easily, film coating on the tooth surface of the gear is more uniform, the film coating thickness is guaranteed, and the film coating quality of the tooth surface of the gear is improved; and the control system comprises a programmable controller, a control model of the programmable controller is a radial basis self-learning neural network, and the machining efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of component coating devices, in particular to a solid lubricating coating coating device for gear tooth surfaces. Background technique [0002] With the development of science and technology, the performance of materials is getting higher and higher. Surface solid lubricating coating technology is an important technology for changing the surface properties of surface materials, and plays a vital role in the preparation of materials. At present, the commonly used methods for surface coating of materials include electroplating, sol-gel, in-situ reaction, thermal spraying, chemical heat treatment, vapor deposition, surface adhesive coating and thermal invasion plating. [0003] At present, the coating technology for flat surfaces is relatively mature, but for some parts with complex working surfaces, such as gears, cams, etc., it is more difficult to coat the working surface of such parts with solid lubricatin...

Problems solved by technology

[0004] The temperature of chemical deposition is high, and many materials cannot meet the high temperature requirements, which limits its use, and the process is difficult to control, and requires processing in a vacuum or protective gas atmosphere, and the airtightness of the equipment is very high. In addition, there are many parameters that need to be controlled during the operation. With the current technology, it is difficult to implement the experimental operation, the cost is high, and the experimental requirements are difficult to guarantee. Therefore, the existing solid lubricating coating for the gear tooth surface There are still great deficiencies in the coating device, which lead to problems such as uneven thickness of the coating film on the gear tooth surface, difficulty in controlling the thickness of the coating film, and poor coating quality.
