Abstract

The invention provides a three-coordinate measuring method for bevel gear tooth form error; the procedures of the method are that: (1) the stop position of measuring bevel gear tooth form error is defined by calculation; (2) positions of other measuring points on the checking part are defined; (3)the actual tooth face is measured by taking the stop position and the theoretical coordinates of measuring points as object points; (4) the tooth form error is worked out. By applying the method of the invention in the tooth form error measurement, the repeatability error can be controlled below 0.004mm, thereby markedly improving the measuring accuracy and being capable of measuring the involute gear below six-grade accuracy. The trend of the involute form of the measuring result is relatively obvious, based on which the depth of the tooth root and the tooth head can be analyzed. According to the measuring result, the gear-cutting machine is guided to be adjusted, achieving good effects.

Description

technical field [0001] The invention relates to a three-coordinate measurement method for the profile error of a helical gear, belonging to the technical field of measurement. Background technique [0002] It is a relatively big problem to detect the helical gear on the three-coordinate measuring machine and guide the machining of the gear through the detection result. In order to meet the detection requirements of helical gears during processing, it is necessary to determine a set of methods and procedures for detecting helical gears on a three-coordinate measuring machine. The currently used methods and procedures have been found to have some problems in the measurement of tooth profile errors. . First of all, the original detection method did not consider the measurement length of the "inspection part" of the tooth profile in the design, but estimated the end point of the measurement part by visual inspection during actual measurement, which may easily cause the measurem...
