Abstract

Worm gears are used frequently in some heavy-duty, high-precision applications, and high-precision worm gear machining relies on high-precision gear hobbing machines. The imported high-precision hobbing machine is expensive, and the research group proposed to use the TE data analysis of the transmission chain to guide the precision improvement of the hobbing machine, thus obtaining a high-precision hobbing machine solution. Firstly, through the transmission error testing system named FMT of the research group, the precision measurement of the transmission error is realized, and the data is analyzed by spectrum to find the large error link. Then, different correction schemes are adopted for different error links to achieve the purpose of eliminating the original error by the reverse error. After many inspections and corrections, the transmission accuracy is greatly improved, and the hobbing machine TE is changed from the initial 26″ to 7.40″. This solution can improve the accuracy of machine tool transmission at low cost and can be applied to other types of machine tools.
