Description
Technical Field
The invention relates to the field of precision testing technology and instruments, in particular to a method for calibrating the mounting position of a 163-degree (or 17-degree) crossed-angle bevel gear pair.
Background
Bevel gear transmission is an important component of gear transmission, and has the characteristics of average load, stable transmission, small vibration, low noise and the like, so that the bevel gear transmission is widely applied to industries such as automobiles, engineering machinery, machine tools, aviation, ships and the like.
Meanwhile, with the development of miniaturization of instruments, the demand of the small-modulus bevel gear is continuously increased, and enterprises have great demands on the rapid measurement of the small-modulus bevel gear. At present, most enterprises adopt a double-faced meshing mode to rapidly measure small-modulus bevel gears.
Before the bevel gear is measured in a double-sided meshing mode, the installation position of the bevel gear needs to be calibrated, and the influence of the installation position error on subsequent measurement results is reduced as much as possible. The mounting position referred to herein is the distance from the reference plane of the bevel gear to the point where the apexes of the two bevel gears meet after the bevel gears are mounted on the shaft. How to quickly and accurately calibrate the mounting position of the small-modulus bevel gear is the key for quickly and accurately measuring the bevel gear by the bevel gear measuring instrument.
The traditional calibration mode mainly adopts a mode of a plug gauge block, but the size of a small-modulus bevel gear is small, the distance of an installation position is small, the traditional mode is difficult to operate, and the precision is difficult to guarantee. This approach presents certain difficulties in calibrating non-90 ° bevel gear pairs.
