Embodiment Construction

[0013] see Figure 1-Figure 3 , when measuring, place the herringbone gear shaft on the workbench of the CNC machine tool, and use the dial indicator to align it in the horizontal and vertical directions, so that the herringbone gear (1), the herringbone gear (2) and the X-axis of the testing machine tool Parallel, set the zero point of the Y axis as the center of the gear axis, that is, Y 1 =O, set the Z-axis zero point as the radius of the pitch circle, that is, Z 1 =O; Then, the electronic measuring contact is installed on the machine tool, at Y 1 = O, Z 1 Under the condition of =0, the center line of the left-handed tooth and the axis intersection (5) where the contact touches the gear (1) is defined as the zero point of the X axis, that is, X 1 =O; then move the contact to the intersection point (6) of the center line of the right-handed tooth of the gear (1) and the axis, and make Y 2 = O, Z 2 =O, record X 2 value; similarly, measure the intersection point (7)Y of ...

Abstract

The invention discloses a double spiral gear phase accuracy testing method that measures the reference circle left right rotating gear center distance of double spiral gear on the same axis section. By taking calculating to gain phase error, the phase error of double spiral gear would be gained after calculating.

Description

Technical field [0001] The invention relates to a detection method of a double herringbone gear, belonging to the technical field of machining measurement. Background technique [0002] At present, the method of measuring the phase of the herringbone gear is to mathematically model the left and right helical tooth surfaces of the herringbone gear, solve the center position of the herringbone gear, and measure it on a three-coordinate measuring instrument. This measurement method is computationally complex and difficult to measure. Contents of the invention [0003] In order to overcome the disadvantages of complex modeling and difficult measurement of the above-mentioned measurement method, the present invention proposes a new measurement method for the phase accuracy of double herringbone gears. Center distance, and through simple mathematical calculations, the phase error is obtained. This method has high measurement accuracy, and the method is simple and convenient to...
