Description

technical field [0001] The invention relates to a herringbone gear slotting processing method based on online detection and compensation of symmetry errors. Background technique [0002] Herringbone gears have the advantages of high load capacity, stable transmission and small axial load, and are widely used in mechanical transmission fields such as ships and heavy machinery. With the development of machinery towards heavy load, high speed and low noise, higher and higher requirements are put forward for the machining accuracy of herringbone gears. In the process of traditional herringbone gear processing, manual scribing and scribing tools are usually used to ensure the symmetry of the gear. Due to the cumbersome operation and the great influence of human factors, the machining accuracy of the gear is poor. At present, the research mainly focuses on In terms of measurement and evaluation of plane symmetry, there is still a lack of specific research on the measurement and e...
