Method for measuring output shaft runout

Abstract

The invention relates to a method for measuring output shaft runout. According to the method, whether a mechanical component abnormally wears or not, and the like, after working is judged by comparingthe difference between a male end runout value measured after the mechanical component finishes scheduled working or fails and a male end runout value measured when the mechanical component is new, and the rotating center of an axis during runout measurement is kept as same as that in the working state. The method for measuring the output shaft runout has the advantages that product quality can be reflected easily and speedily, production inspection in outside plants is facilitated, production returning and disassembling is avoided, period is saved, and working efficiency is improved.

Description

technical field [0001] The invention relates to a measuring method, in particular to a method for measuring the runout of an output shaft, aiming at accurately measuring the runout of the output shaft under the actual working stress state of a gear transmission box. Background technique [0002] In the mechanical device, due to the certain fit gap between the gears, bearings, bearing bushes and other parts, the interaction force of the gears will cause a certain deviation in the direction of the force during work. In addition, with the extension of the working time , it will inevitably cause wear of the mechanical parts, resulting in an increase in the fit gap between the parts, and an increase in the offset during work, which will reduce the positioning and transmission accuracy and cause the entire mechanical device to work. The performance is degraded, and in severe cases, it will directly cause the mechanical device to fail to work normally. At present, the commonly use...

[0002] In the mechanical device, due to the certain fit gap between the gears, bearings, bearing bushes and other parts, the interaction force of the gears will cause a certain deviation in the direction of the force during work. In addition, with the extension of the working time , it will inevitably cause wear of the mechanical parts, resulting in an increase in the fit gap between the parts, and an increase in the offset during work, which will reduce the positioning and transmission accuracy and cause the entire mechanical device to work. The performance is degraded, and in severe cases, it will directly cause the mechanical device to fail to work normally

At present, the commonly used measurement method to evaluate the overall quality of the mechanical transmission system is to measure the end face and radial runout of the output shaft rotation center axis relative to the outer stop, that is, to fix the measurement meter frame on the output shaft, and put the pointer against the outer stop. Rotate the meter frame for a circle, and read the measured value through the dial. The measurement in this way reflects the measured value of the mechanical device under static conditions, and the measured value is affected by the shape and position tolerance of the outer stop itself, which cannot reflect the product. Real transmission accuracy, especially for products with wear and tear after work, the measurement results are quite different from the actual state of the product, and cannot reflect the actual state of the product
