Problems solved by technology

The disadvantage is that it can only detect the finished workpiece, which is not conducive to the detection of parameter adjustment between processes, especially for bevel gears whose root cone is not enough to collect 10-30mm straight lines due to small modulus or small tooth root area. If the probe interferes, one or two teeth need to be destructively ground to achieve the purpose of detection

Embodiment

[0028] A bevel gear for aviation products, the part is in blank state. The drawing indicates that the specified height is 10mm, and the cone angle is 69°4′16″. When the height is 10mm, the diameter of the root vertebra section circle is φ225.677mm. It is required to measure the gear to obtain the final cone angle, Specify the section circle diameter and specify the section height value.

[0029] The specific operation steps are as follows:

[0030] (1) Processing: prepare the bevel gear to be tested, and process the gear until there is at least one complete dedendum;

[0031] (2) Establish a coordinate system: according to the requirements of the design drawings, place it on the basis of the principle of the minimum number of rotation angles of the probe of the three-coordinate measuring machine, and use the three-coordinate measuring machine to collect the benchmark of the gear to be measured, and establish a measurement coordinate system;

[0032] (3) Collect sample points...

Abstract

The invention relates to a method for detecting the root cone parameters of bevel gears. The method for detecting the points on the root cone surface of the bevel gear by using a three-coordinate measuring machine realizes the detection of the root cone parameters. Compared with the old measuring method, the detection speed is faster and touch The measuring area is small, and it can be detected by only processing a pair of teeth during the process, which solves the defects that the finished workpiece must be inspected and the workpiece must be destroyed to measure.

Description

technical field [0001] The invention relates to a measuring method, a method for detecting bevel gear tooth root cone parameters. Background technique [0002] The bevel gear is an important part of the transmission system, and its root cone (root cone) parameter is an important tooth shape technical parameter, which affects the uniformity of the carburized layer distribution at the bottom of the gear tooth, and then affects the overall performance of the entire bevel gear index. The detection accuracy of bevel gear root-cone parameters has a great influence on its bevel gear processing: during rough machining of bevel gear, if the measurement is not accurate, it will lead to insufficient allowance for grinding and finishing (tooth stage); during bevel gear finishing, if If the measurement is not accurate, the carburized layer of the gear will be damaged, and both cases will cause the bevel gear to be scrapped in batches. Therefore, the detection of bevel gear root-cone pa...
