Centering control structure and processing method of internal and external teeth of high-speed precision heavy-duty herringbone gear

Abstract

The invention discloses a centering control structure and processing method of internal and external teeth of a high-speed precision heavy-duty herringbone ring gear. Firstly, the internal helical teeth of the two ring gears are separately processed, and the dimensional accuracy of the internal teeth is improved through fine grinding. , so as to ensure the high-precision symmetry of the internal teeth of the left-handed ring gear and the right-handed ring gear, and the center plane is centered, and then the left-handed ring gear and the right-handed ring gear are calibrated on the calibration tool, by putting the two ring gears on the same calibration To ensure that the two ring gears are coaxial, the outer teeth of the correction piece are respectively meshed with the inner teeth of the two ring gears to ensure that the phase angles of the two ring gears are consistent, and the two ring gears are respectively clamped by two pressing parts. Tightly fix it on the calibration piece to ensure that the two ring gears are completely attached to the two ends of the positioning piece. At this time, the center plane of the positioning piece is the center plane of the inner herringbone tooth, and also serves as the processing reference for the center plane of the outer herringbone tooth. For external gear processing, medium precision and high precision processing are required, the processing efficiency is improved, and it is convenient for mass production processing.

Description

technical field [0001] The invention relates to the field of gear processing, in particular to a high-speed precision heavy-duty herringbone ring gear centering control structure and processing method for inner and outer teeth. Background technique [0002] The herringbone tooth is a cylindrical gear. The herringbone tooth is composed of two sets of helical teeth with different rotation directions on the left and right. The axial forces of the left and right sets of helical teeth in the transmission process cancel each other out, and the gear transmission adopts two sets of helical teeth. Gear meshing transmission, high bearing capacity, stable transmission, especially suitable for applications in heavy machinery, such as ships and other high-power transmission occasions. [0003] The plane where the left and right tooth shape extension lines of the herringbone tooth intersect is the center plane of the herringbone tooth. When there is a phase difference or coaxiality error ...
