Abstract

The invention discloses a method and system for fast centering of double gear tooth grooves, comprising the following steps: Step 1: preparing a calibration piece and a dual-sensor measuring device; Step 2: clamping the calibration piece, and installing a dual-sensor measuring device; Step 3 : Collect the position signals of all the tooth slots of the first and second gears on the calibration piece; Step 4: find out the two slots closest to the center of all the slots of the first gear and the second gear on the calibration piece, and calculate the calibration Part offset angle and direction; step 5: remove the calibration part, install the part to be processed; collect the position signals of all the tooth grooves of the first gear and the second gear on the part to be processed; step 6: calculate the offset angle of the part to be processed and direction; Step 7: Calculate the angle and direction to be compensated; Step 8: Compensate the workpiece rotation axis according to the offset value and direction. According to field verification, after adopting the present invention, the position accuracy of tooth alignment can reach within 0.05mm; at the same time, the centering time can be within 10s, and the efficiency can be increased by more than 1 times.

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 grooves. 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 co...
