Abstract

The invention discloses a method for manufacturing a super-long and high-precision shaft gear, which solves the technical problems of processing and manufacture of accelerator and decelerator transmission devices of super-long and high-precision shaft gears. The method lays a foundation for realizing precision grinding of the super-long and high-precision shaft gear by using a numerical control gear grinding machine and improving the steps of tool preparation and installation and workpiece clamping and adjustment in the manufacture process. The method has the advantages of realizing the manufacture of the super-long shaft gear with shaft length of 4,800 millimeters, solving the problem that the super-long shaft gear cannot be processed at present, meeting the development requirements of new products, adjustably fluctuating precise superposition of the public central line of a lower apex and an upper apex and the rotary central line of a machine tool, reducing installation eccentricity of the gear, improving the processing precision of the gear, reducing the trouble when the conventional gear is installed and corrected, effectively shortening the installation and correction time and improving the work efficiency. According to the super-long and high-precision shaft gear processed by the manufacturing method, the maximum diameter is 2,000 millimeters, the shaft length is 4,800 millimeters, the shaft diameter is less than 900 millimeters, and the precision can reach levels 2 to 5 of DIN3962 standards.

Description

Technical field: [0001] The invention relates to a manufacturing method of a transmission device, in particular to a manufacturing method of an ultra-long, high-precision shaft gear. Super-long, high-precision shaft gears can be widely used in large-scale transmission mechanisms such as speed increasers and reducers. Background technique: [0002] In the transmission device of the increaser and reducer, it is often necessary to provide super-long and high-precision shaft gears. But at present, in China, no matter imported or domestic gear grinding machine tools, it is impossible to realize the processing and manufacturing of ultra-long, high-precision shaft gear increaser and reducer transmission devices. Invention content: [0003] In order to solve the technical problem of being unable to realize the processing and manufacturing of super-long and high-precision shaft gears, the present invention provides a method for manufacturing super-long, high-precision shaft gears....
