Problems solved by technology

[0005] The traditional calibration method mainly adopts the method of plug gauge block, but the size of the small modulus bevel gear is small, and the distance between the installation positions is also small. The traditional method is difficult to operate and the accuracy is difficult to guarantee.

Abstract

The invention discloses a double-flank measurement calibration method for small modulus bevel gear pair with a 90 DEG crossed axes angle, belonging to the technical field of precision test and instrument and mechanical drive. The double-flank measurement calibration method includes the steps: customizing a calibration block according to a theoretical installation location to be calibrated; and installing the calibration block on a corresponding axle, adjusting the location of the axle to enable the calibration block to attach to the bus of the other axle, thus completing calibration of the installation location of one axle, and repeating the above operations on the other axle to complete calibration of the installation location of the two axles. The double-flank measurement calibration method for small modulus bevel gear pair with a 90 DEG crossed axes angle has the advantages of simple and convenient operation, high precision and high speed, and is suitable for calibration of the installation location of the bevel gear with a 90 DEG crossed axes angle.

Description

technical field [0001] The invention relates to the field of precision testing technology and instruments, in particular to a method for measuring and calibrating double meshing of a small-modulus bevel gear pair with a 90° axis intersection angle. Background technique [0002] Bevel gear transmission is an important part of gear transmission. Because of its characteristics of average load, stable transmission, low vibration and low noise, it is widely used in automobiles, construction machinery, machine tools, aviation, ships and other industries. [0003] At the same time, with the development of miniaturization of instruments, the demand for small-module bevel gears is also increasing, and enterprises also have a great demand for rapid measurement of small-module bevel gears. At present, most companies use the double-sided meshing method to quickly measure small-module bevel gears. [0004] Before measuring the bevel gear by the double-sided meshing method, the installat...
