The comprehensive measurement method and technology of large gears are still developed from the comprehensive measurement of medium and small module gears, and the comprehensive measurement method of single side meshing is worthy of attention. This has been fully reflected in the measurement of medium and small module gears. Through data processing, single error items such as tooth profile, tooth direction and tooth pitch can be obtained, but the former belongs to the category of geometric error and the latter belongs to the category of transmission error, that is, the single error under the transmission frame. How to transplant it to large gear measurement is a problem worthy of discussion. As a direction of precision measurement of large gears, single-sided meshing comprehensive measurement has the advantages of small instrument volume, convenient installation and large error information, but there are still many technical problems, such as the manufacture of tool components.
From the perspective of the whole measurement technology development of large gears, the positive experience and ideas can be summarized as follows:
(1) From the perspective of the development of large gear measurement technology, it is developed with the help of precision measurement technology of sub medium and small module gear and considering the characteristics of large gear, which is mainly reflected in the desktop measuring instrument, and this development mode is the characteristic of today’s technology development. Based on the mature measurement technology of medium and small module gears and some changes according to the actual particularity of large gears, a new measurement technology is formed. When completing the work of this paper, it is very important to absorb these rich experience as much as possible, which is also in line with the relationship between inheritance and development.
(2) It reflects the relationship between quantitative change and qualitative change. Due to the increase of the size and weight of the measured object, it is difficult to implement the measurement technology of medium and small module gears, which has produced a significant change in quality, so it is necessary to develop a new way“ “The ant gnaws at the bone” is a kind of image statement. Its idea has been fully reflected in heavy machinery processing, and it should also be suitable in the field of measurement. The upper type and the side type quantity reflect this idea.
(3) From the development trend of large gear measurement technology, the combination of traditional technology and modern high and new technology is an important feature of the development of large gear measurement technology. Microelectronics technology and laser technology have played and continue to play a leading role in large gear measurement.
(4) It is an important aspect of large gear measurement technology to solve the problems in large gear measurement, such as the accuracy of large reference elements, precision adjustment and alignment, measurement datum conversion and measurement efficiency.
Based on the above analysis, the side measurement method of large gear is likely to be an important direction of large gear measurement technology, and its advantages have been reflected in the comparison of the above three methods. The existing problem is the original error of the machine tool, which can be solved by using the rapidly developing compensation technology. In a broad sense, the single error measurement method and the comprehensive error measurement method have good development prospects. This paper focuses on the on-line measurement method, which is the Enlightenment of literature review and review.
