Example Embodiment

[0025] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the drawings are exemplary, and are only used to explain the present invention, but should not be understood as limiting the present invention.

[0026] In the figure, the main ruler part 1, the measuring part 2, and the outer measuring end 2a and the inner measuring end 2b.

[0027] Such as figure 1 As shown, the method for measuring the major diameter of the odd tooth or spline uses a trigonometric function to measure the major diameter of the odd tooth or spline at three points. The specific relationship is as follows:

[0028] Angle β: β=180°-360° / Z (where Z is the number of teeth of odd teeth);

[0029] α=180 / Z

[0030] h is the measured value

Abstract

The invention discloses a measuring method and measuring equipment of the large diameter of an odd number gear or a spline. The large diameter of the odd number gear or the spline, namely the h value, is measured according to the following formula: r is the radius of an external circle of the odd number gear or the spline, alpha is 180 degrees/Z, and Z is the tooth number of the odd number gear. The measuring method and the measuring equipment can solve the fast measurement problem of the odd number gears and spines of various specifications on a production site, have the advantages of being low in production cost, convenient and fast, and are particularly suitable for production application.

Description

Technical field [0001] The invention relates to a measuring method for measuring the large diameter of an odd gear or spline to be measured and a corresponding measuring device. Background technique [0002] Three-coordinates is a three-coordinate measuring machine, which refers to an instrument that can calculate various geometric shapes, dimensions and other measurement capabilities through a three-coordinate software system based on the point data returned by the probe system within the three-dimensional measurable space range, also known as It is a three-coordinate measuring instrument or three-coordinate measuring bed. [0003] Nowadays, measuring the large diameter of odd-numbered gears in various industries cannot use general measuring tools such as vernier calipers, outside micrometers, etc. to measure, generally three-coordinate measurement is required, and the three-coordinate measurement needs to be in a special place, and the measurement efficiency is low. The high cos...
