Abstract

The invention discloses a duplicate gear tooth groove rapid centering method and system. The duplicate gear tooth groove rapid centering method comprises the following steps that 1, a calibration piece and a double-sensor measuring device are prepared; 2, the calibration piece is clamped, and the double-sensor measuring device is installed; 3, position signals of all tooth grooves of a first gear and a second gear on the calibration piece are collected; 4, two tooth grooves with closest centers in all the tooth grooves of the first gear and the second gear on the calibration piece are found out, and the offset angle and direction of the calibration piece are calculated; 5, the calibration piece is taken down, and a to-be-machined piece is installed; position signals of all tooth grooves of the first gear and the second gear on the to-be-machined piece are collected; 6, the offset angle and direction of the to-be-machined workpiece are calculated; 7, an angle and a direction which need to be compensated are calculated; and step 8, a workpiece rotating shaft compensates according to the offset value and direction. Through on-site verification, after the method is adopted, the tooth alignment position precision is within 0.05 mm; and meanwhile, the centering time is within 10s, and the efficiency is improved by more than one time.

Description

technical field [0001] The invention belongs to the field of construction machinery, and in particular relates to a method and a system for fast centering of double gear tooth slots. Background technique [0002] In the field of gear transmission, it is often faced with the situation that certain two tooth slot positions of the two ring gears are required to have a strict alignment relationship during the finishing of the double gear. The traditional method is to finish the two ring When using the alignment tool to ensure the position of the tooth groove, because the suit is generally an interference fit, the centering tool has a complex structure and low centering accuracy. When the two ring gears cannot be fitted together and are designed as one piece, processing means must be used to ensure the alignment of the two tooth grooves. At present, the alignment methods often used in processing include manual measurement compensation alignment, sensor automatic measurement comp...
