[0037] The rotating mechanism can be a power mechanism such as a motor or a rotating cylinder that can provide torque.

[0038] In some embodiments, the cam 11 and the input shaft 1 may be integrated into one structure, or the cam 11, the mounting flange 101 and the input shaft 1 may be integrated into one structure. The wave generator provided in this application is mainly used for testing the reducer body, so such a design is conducive to further improving the convenience of the test operation.

[0040] With such arrangement, when the wave generator or the input shaft 1 needs to be replaced, after releasing the installation connection between the mounting adapter 2 and the flexible wheel 801 of the reducer body 8, the output shaft and the reducer body 8 are removed from the input shaft 1 as a whole in a connected state, so that the connection position between the wave generator and the mounting flange 101 can be exposed. Since the output adapter 4 is connected to the end of the input shaft 1, the removal operation is quick and convenient, and is faster than moving the mounting adapter 2 to slide along the input shaft 1.

[0041] In another preferred embodiment, the wave generator is connected to the mounting flange 101 by a first screw 5, and the head of the first screw 5 faces the side where the output adapter 4 is located; specifically, both the wave generator and the mounting flange 101 are provided with threaded holes, or only the wave generator is provided with threaded holes.

[0042] With such arrangement, when the wave generator or the input shaft 1 needs to be replaced, after releasing the installation connection between the mounting adapter 2 and the flexible wheel 801 of the reducer body 8, the output shaft and the reducer body 8 are removed from the input shaft 1 as a whole in a connected state. In particular, when the output adapter 4 is rotatably connected to the end of the input shaft 1, the head of the first screw 5 connecting the wave generator and the mounting flange 101 is quickly exposed, so that there is no obstruction to unscrewing the first screw 5, which is convenient for the tester to operate.

[0045] Such a configuration is beneficial to the rapid positioning connection between the flexible wheel 801 of the reducer body 8 and the mounting adapter 2, further improving the testing efficiency of the reducer body 8; moreover, the mounting adapter 2 forms reliable positioning and limiting for the flexible wheel 801 in both the axial and circumferential directions, which is also beneficial to improving the testing accuracy.

[0046] It should be noted that the detachable connection between the flexible wheel 801 of the reducer body 8 and the mounting adapter 2 can be achieved by connecting with the second screw 6 .

[0047] In another specific embodiment, a rigid wheel positioning groove 401 is provided on the side of the output adapter 4 facing the mounting adapter 2. The rigid wheel positioning groove 401 is recessed along the axial direction. The rigid wheel positioning groove 401 is used to accommodate at least part of the rigid wheel 802, or the output adapter 4 forms a circumferential limit on the rigid wheel 802.

[0048] Such a configuration is beneficial to the rapid positioning connection between the rigid wheel 802 of the reducer body 8 and the output adapter 4, further improving the testing efficiency of the reducer body 8; moreover, the output adapter 4 forms reliable positioning and limiting for the rigid wheel 802 in both the axial and circumferential directions, which is also beneficial to improving the testing accuracy.

[0049] It should be noted that the assembly and disassembly connection between the rigid wheel 802 of the reducer body 8 and the output adapter 4 can be achieved by connecting through the third screw 7 .

[0050] In another preferred embodiment, the wave generator is provided with a sinking groove 301 which is recessed in the axial direction, and the mounting flange 101 is located in the sinking groove 301. It is preferably arranged that the mounting flange 101 is consistent with the sinking groove 301.

[0051] With such arrangement, when the wave generator is installed on the input shaft 1, the side where the groove 301 is located is the side where the wave generator is used to connect with the mounting flange 101 of the input shaft 1, which serves as a reminder and forms a fool-proof design. The test personnel do not need to spend time distinguishing the front and back sides of the connection, which is conducive to further improving the test efficiency.

[0052] In another specific embodiment, the mounting adapter 2 is rotatably connected to the input shaft 1 through the first bearing 9, and the input shaft 1 is provided with a first shaft shoulder 102 for positioning the first bearing 9. In this way, the first bearing 9 is in contact with the first shaft shoulder 102 in the axial direction, which plays a role in positioning and assembling, and is conducive to the stability and reliability of the axial position of each component structure after the reducer test fixture and the reducer body 8 form an assembly relationship, which is conducive to assisting in improving the test accuracy.

[0053] In another specific embodiment, the output adapter 4 is rotatably connected to the input shaft 1 through the second bearing 10, and the input shaft 1 is provided with a second shaft shoulder 103 for positioning the second bearing 10. In this way, the second bearing 10 is in contact with the second shaft shoulder 103 in the axial direction, which plays a role in positioning and assembling, and is conducive to the stability and reliability of the position of each component structure in the axial direction after the reducer test fixture and the reducer body 8 form an assembly relationship, which is conducive to assisting in improving the test accuracy.

[0055] In this arrangement, since the output adapter 4 is connected to the end of the input shaft 1 and needs to withstand axial force, the thickened design of the center part of the output adapter 4 is conducive to better bearing the axial force and ensuring the overall stability of the reducer test fixture.

[0056] The test results of the reducer test fixture formed by the above-mentioned embodiments show that the flexible bearing of the wave generator has a longer structural life and service life than the existing conventional test fixtures.
