[0024] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0025] Embodiment 1:

[0026] like Figure 1 This is a schematic diagram of the structure of the utility model, a gearbox test bench, comprising:

[0027] The base 1 is provided with a plurality of chute grooves 11 which are spaced apart from each other and are T-shaped grooves;

[0028] like Figure 1 , Figure 2 , Figure 3 As shown, a test mechanism 2 is used to detect the performance of a gearbox 3. The test mechanism 2 comprises a base 21, a first bracket 22, a second bracket 23, a test motor 24 and a connecting shaft 25. The first bracket 22 and the second bracket 23 are installed on the base 1 at intervals, and there is a gap between the first bracket 22 and the second bracket 23 for installing the gearbox 3. The test motor 24 is installed on a side of the first bracket 22 away from the second bracket 23. The test motor 24 is used to provide power for the gearbox 3. The output end of the test motor 24 is connected to one end of the gearbox 3, and one end of the connecting shaft 25 is drivingly connected to the other end of the gearbox 3. The connecting shaft 25 is arranged on the second bracket 23. The connecting shaft 25 is used to connect to external equipment. The base 21 is arranged on the base 1 through a connecting piece 26, so that the position of the test mechanism 2 can be adjusted and locked.

[0029] like Figure 2 , Figure 3 As shown, the connecting member 26 includes a locking member 261 and a slider 262. The slider 262 matches the slide slot 11. The slider 262 and the slide slot 11 are slidably connected. The locking member 261 passes through the base 21 and is threadedly connected to the slider 262. The locking member 261 can be a bolt. The locking member 261 can rotate to make the slider 262 move away from or close to the locking member 261.

[0030] When the position of the testing mechanism 2 is fixed, the slider 262 abuts against the base 1 .

[0031] Two stabilizing components 4 for absorbing vibration of the gear box 3 are installed at intervals on the bottom surface of the base 21 to absorb the vibration generated by the gear box during transmission, thereby reducing its impact on the connection, so that the installation of the gear box is more in line with the actual situation, thereby improving the accuracy of the test results.

[0032] The stabilizing assembly 4 includes a mounting seat 41 and a contact block 42. The mounting seat 41 is fixedly connected to the base 21. The mounting seat 41 matches the slide groove 11. The mounting seat 41 is arranged in the slide groove 11. The bottom surface of the mounting seat 41 is provided with a receiving groove 411 which is inclined from top to bottom toward the side of the base 21 on its side. The contact block 42 is elastically arranged in the receiving groove 411, and the bottom surface of the contact block 42 contacts the base 1.

[0033] The stabilizing assembly 4 includes an elastic element 43 . The elastic element 43 is arranged in the receiving groove 411 . One end of the elastic element 43 abuts against the mounting seat 41 , and the other end abuts against the abutting block 42 .

[0034] The abutment blocks 42 of the two stabilizing components 4 gradually move away from each other from top to bottom, so that the abutment blocks 42 tilt in opposite directions, thereby mainly eliminating vibration along the extension direction of the slide slot 11 and preventing the test mechanism 2 from vibrating in the extension direction of the slide slot 11 .

[0035] Embodiment 2:

[0036] The stabilizing assembly 4 includes a mounting seat 41 and two abutment blocks 42. The mounting seat 41 is fixedly connected to the base 21. Two receiving grooves 411 are provided on the mounting seat 41. The two receiving grooves 411 gradually move away from each other from top to bottom. The receiving grooves 411 and the abutment blocks 42 correspond one to one. The abutment blocks 42 are elastically arranged in the receiving grooves 411 so that the abutment blocks 42 are tilted in opposite directions, thereby mainly eliminating vibrations along the extension direction of the slide groove 11 and avoiding vibrations of the test mechanism 2 in the extension direction of the slide groove 11.
