Problems solved by technology

[0003] In the prior art, in the process of manufacturing the oil slinger assembly of an aircraft engine, the oil slinger is finally obtained through machining, coating spraying, assembly and grinding and other assembly and manufacturing methods on the individual parts of the oil slinger assembly Assemblies, however, the coating in the final oil flinger assembly is ground with low uniformity, and the local coating is too thin, which leads to low manufacturing accuracy and high rejection rate of the oil flinger assembly Happening
[0004] In the above prior art, the defects of low manufacturing precision in the assembly and manufacturing process of the oil thrower assembly and high rejection rate of the oil thrower assembly are technical problems that need to be solved by those skilled in the art

Abstract

The invention relates to the field of aviation technology, in particular to a method for manufacturing an oil thrower assembly of an aircraft engine. The manufacturing method of the oil slinger assembly of the aircraft engine comprises: plugging and assembling the grate tooth sealing ring and the oil slinger base to form the assembly blank body of the oil slinger assembly; processing the coating ring on the assembly blank body groove; spray coating on the coating ring groove; grind the coating according to the preset size. Through the application of this method, the processing of the coating ring groove, spraying coating and grinding coating are all carried out on the basis of plugging and assembling the grate sealing ring and the base of the oil slinger to form an assembly blank body. This makes the above-mentioned processing steps all take the assembled blank body as the overall processing object and the clamping positioning reference. Therefore, the application of the present application significantly improves the machining accuracy of the oil flinger assembly of the aircraft engine and reduces the reject rate.

Description

technical field [0001] The invention relates to the field of aviation technology, in particular to a method for manufacturing an oil thrower assembly of an aircraft engine. Background technique [0002] A variety of manufacturing methods need to be applied in the process of manufacturing aircraft engines. Among them, in the process of manufacturing and assembling the oil thrower assembly of the aircraft engine, it needs to be manufactured by grinding and other methods. At present, the manufacturing accuracy of the aircraft engine and the oil thrower assembly , and the requirements for product durability are getting higher and higher. Therefore, improving manufacturing precision and product durability has become a design goal. [0003] In the prior art, in the process of manufacturing the oil slinger assembly of an aircraft engine, the oil slinger is finally obtained through machining, coating spraying, assembly and grinding and other assembly and manufacturing methods on the...
