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.
This method has certain difficulties in calibrating bevel gear pairs with non-90° axis crossing angles

Abstract

The invention discloses a 163-degree or 17-degree crossed axis angle bevel gear pair mounting position correction method and belongs to the technical field of precision testing technology and instruments and mechanical transmission. The method includes: according to a theoretic mounting position needing to be corrected, customizing a correction shaft and a correction sleeve; respectively mountingthe correction shaft and the correction sleeve on corresponding shafts, slightly adjusting positions of the shafts to enable the correction shaft and the correction sleeve to fully contact, and then resetting a grating scale to realize mounting position correction. The method has the advantages of simplicity and convenience in operation, high accuracy and high speed and is suitable for correctingmounting position of bevel gears of 17 degree (or 163 degree) in crossed axis angle during double-side meshing measurement.

Description

technical field [0001] The invention relates to the field of precision testing technology and instruments, in particular to a method for calibrating the mounting position of a bevel gear pair with a 163° (or 17°) 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, small vibration and low noise, it is widely used in industries such as automobiles, construction machinery, machine tools, aviation, and ships. [0003] At the same time, with the development of instrument miniaturization, the demand for small modulus bevel gears is also increasing, and enterprises also have a great demand for rapid measurement of small modulus bevel gears. At present, most enterprises use double-sided meshing to quickly measure small modulus bevel gears. [0004] Before measuring the bevel gear with the double-sided meshing method, the installation position ne...
