Abstract

The invention discloses a herringbone gear slotting processing method based on on-line detection and compensation of symmetry error. The method comprises that a mathematical model of the symmetry error of detection and compensation of a herringbone gear is established based on the spatial planar fitting method, least square method and the symmetric error equivalent processing method, the symmetryerror of herringbone gear is calculated and expressed through the mathematical model calculation, and the on-line detection and compensation processing of the symmetry error is accomplished by using amotion shaft and a numerical control system of a numerical control gear plugging machine.

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...
