Background Art

[0002] In mechanical transmission systems, spiral bevel gears and hypoid gears are widely used in various machines and equipment, especially in situations where the direction of movement needs to be changed and power needs to be transmitted. With their excellent transmission efficiency, stable operating performance and high load-bearing capacity, they have become an indispensable and important part of modern mechanical design. However, with the advancement of science and technology and the continuous improvement of industrial needs, traditional gear design and testing methods have gradually exposed their shortcomings, especially when the shaft angle and offset distance change greatly, making it difficult to guarantee the meshing performance and transmission accuracy of the gears.

[0003] The existing technology lacks research on the effects of axis angle and offset on the tooth contact stress and wear unevenness of spiral bevel gears and hypoid gears. The lack of a comprehensive test platform for spiral bevel gears and hypoid gears makes it difficult to conduct comparative tests on different types of gears under the same environment. This limitation not only restricts the performance optimization of gears, but also reduces the research and development efficiency of new gear designs. Therefore, it is particularly important to develop a four-axis linkage test method and device that can adapt to any axis angle and offset. Summary of the invention

[0041] The testing method based on the spiral bevel gear and hypoid gear four-axis linkage testing device comprises the following steps:

[0042] S1. Install the rotating shafts of the input end gear 5 and the output end gear 14 on the corresponding input end bearing 44 and the output end bearing 73 through the coupling, and adjust the shaft angle between the input shaft of the input end gear 5 and the output shaft of the output end gear 14 through the shaft angle adjustment module 1;

[0043] By rotating the indexing plate 12, the change of the shaft angle can be accurately controlled so as to test the gear performance under different conditions.

[0044] S2, such as Figure 4 As shown, when the shaft angle changes, the installation distance between the input shaft of the input end gear 5 and the output shaft of the output end gear 14 will change. In order to compensate for this change, it is necessary to perform precise adjustment through the Y-direction displacement adjustment module 6 and the X-direction displacement adjustment module 9;

[0046]

[0047]

[0048] In the formula, is the axis intersection angle, is the change in the axis angle, It is the distance between the rotation center of the indexing plate and the intersection of the input shaft and the output shaft;

[0049] According to the above formula, the position is compensated by the Y-direction displacement adjustment module 6 and the X-direction displacement adjustment module 9 to ensure that the gear shafts between the input end and the output end are precisely aligned. During the adjustment process, the relative positions of the input shaft of the input end gear 5 and the output shaft of the output end gear 14 need to be repeatedly measured until the predetermined accuracy requirement is reached;

The entire adjustment process can be completed on a single experimental platform without the need for additional adjustment equipment, greatly improving test efficiency and the applicability of the test device. During the test, the experimenter can adjust the speed of the input gear through the variable speed drive motor module to simulate the gear transmission characteristics under different working conditions.

[0052] To ensure the accuracy of the test results, all modules need to be calibrated before testing. First, use a laser rangefinder to calibrate the displacement of the displacement adjustment module in the X, Y, and Z directions to ensure the accuracy of each adjustment. Then, use a standard gear to verify the alignment of the input and output gear modules to determine whether the accuracy of the axis angle adjustment module 1 meets the requirements. After the calibration is completed, record all initial parameters for comparison during the test.

[0053] During the test, the experimenter can set different shaft angles and offset distances according to actual needs, and record the test data under each working condition. Compare and analyze the performance of gears under different working conditions, so as to provide data support for gear design and improvement.
