Embodiment Construction
[0043] The present invention will be described in detail below with reference to the drawings and embodiments.
[0044] see figure 1 From the perspective of gear meshing, literature [2] proposes to measure the position coordinates of the measurement points on the contact line of the tooth surface on the same side of the teeth on both sides of the herringbone gear, and perform linear fitting on the data of the measurement points to calculate the fitted actual The distance between the contact line intersection and the center plane ΔT h , the symmetry error of the herringbone gear can be obtained.
[0045] see figure 2 , an online detection method proposed in literature [3] is to move the tool in the Y-axis direction Y 1 The coordinate X of the tooth profile on the X axis at a distance 1 ;When moving from the upper end surface to the middle position, take the tool movement distance in the Y direction as Y 1 The abscissa of the intersection point with the tooth profile is X ...

The invention relates to the technical field of gear measurement methods, in particular to a section method herringbone gear symmetry error rapid measurement method. The problems that in the prior art, the requirements for efficiency and precision cannot be met at the same time, and the measurement efficiency is generally low are solved. According to the technical scheme, firstly, measurement characteristics are selected on gear teeth of a gear; secondly, determining a measurement basis, and detecting measurement characteristics on a CNC gear measurement center; and finally, the herringbone gear symmetry error is obtained. According to the invention, accurate measurement of the symmetry error of the herringbone gear can be realized, from the angle of the tooth profile characteristics of the gear teeth, the position coordinates of all measurement points on the whole tooth trace are not required to be measured by measuring the position coordinates of a small number of measurement pitch points on the tooth trace, rapid measurement is realized, and the method can be suitable for measurement of the gear before line correction. Meanwhile, the device is also suitable for measuring the corrected gear.
Description
Technical field: [0001] The invention relates to the technical field of gear measurement methods, in particular to a method for quickly measuring the symmetry error of a herringbone gear by a section method. Background technique: [0002] Herringbone gears are widely used in large-scale power equipment such as heavy ships and aerospace because of their high load-carrying capacity and small axial load. The symmetry of the tooth surfaces on both sides of the herringbone gear with respect to the center plane directly affects the uniformity of the contact load distribution, resulting in vibration and noise during the transmission process, thereby affecting the service life of the herringbone gear. Therefore, the research on the detection and evaluation method of the tooth symmetry error on both sides of the herringbone gear has important theoretical significance and engineering application value for its design and manufacture. [0003] The current measurement technology for the...
