Connecting brackets are fixedly connected to both ends of the sliding sleeve. The top of the two connecting brackets is fixedly connected to the same mounting tray for placing the speed reducer to be tested. The front and rear edges of the mounting tray extend upward to form side plates, which limit the movement of the speed reducer.

[0023] It should be noted that the test host 21 is existing technology and serves as the "power source" and "data sensing core" for the speed reducer test. It mainly undertakes two core tasks: first, to provide adjustable and stable speed and torque power to the speed reducer under test, simulating the actual working conditions of the speed reducer; second, to collect key parameters (such as speed, torque, and operating temperature) in real time during the power output process and feed them back to the data processing host 26 through data transmission components, such as data cable 28, to provide raw data support for speed reducer performance analysis. This is common knowledge for those skilled in the art and will not be elaborated upon here.

Support frames 4 are fixedly connected to both ends of the bottom of the workbench 1 for stable support. The testing component 2 and the speed reducer mounting and transmission component 3 are symmetrically arranged on the top surface of the workbench 1 to facilitate power transmission and testing coordination. The testing component 2 includes a testing host 21 fixedly mounted on one side of the top of the workbench 1 to provide the power required for testing. A housing 22 is fitted over the testing host 21 for protection, and heat dissipation fins are fixedly connected to the outer wall of the housing 22. Plate 23 can quickly dissipate the heat generated by the test host 21 during operation, ensuring the stable operation of the test host 21. A test shaft 24 is fixedly connected to the output end of the other side of the test host 21 for transmitting power. A first connecting plate 25 is fixedly connected to the end of the test shaft 24 away from the test host 21. The test assembly 2 also includes a data processing host 26 fixedly installed on one side of the front end of the workbench 1 for collecting and processing test data. A control panel 27 is set at the front end of the data processing host 26 for convenient parameter setting and operation by the operator. The data processing host 26 is connected to the test host 21 through a data cable 28 to ensure real-time transmission of test data. The gearbox installation transmission assembly 3 includes a slide rail 31 fixedly installed on the other side of the top of the workbench 1. A sliding sleeve 32 is slidably mounted on the slide rail 31, which can slide along the slide rail 31 to adapt to different installation distances. Both ends of the sliding sleeve 32 are fixedly connected to connecting brackets 33. The top of the two connecting brackets 33 is fixedly connected to the same mounting tray 34 for placing the gearbox to be tested. The front and rear edges of the mounting tray 34 extend upward to form side plates 35, which limit the movement of the gearbox. The side plates 35 have symmetrically arranged waist-shaped holes 36 between the front and rear side walls, which facilitates fixing the gearbox to the side plates 35 with bolts or other fasteners, adapting to different specifications of gearboxes. The speed reducer mounting hole positions, the speed reducer mounting transmission assembly 3 also includes two balance supports 38 that are symmetrically fixedly connected to the top of the sliding sleeve 32. Balance bearings 39 are installed on the balance supports 38. A transmission shaft 310 is inserted through the balance bearings 39, which can stably support the transmission shaft 310 and ensure its smooth rotation. One end of the transmission shaft 310 is fixedly connected to a second connecting plate 311 that cooperates with the first connecting plate 25, for connecting with the first connecting plate 25 of the test assembly 2 to transmit power. The other end of the transmission shaft 310 is fixedly connected to a connecting seat 312. The other end of the connecting seat 312 has a connecting hole 313 for connecting with the output end of the speed reducer to be tested.

[0025] The heat dissipation fins 23 are arranged in an array on the outer wall of the outer shell 22, and the heat dissipation fins 23 are made of aluminum alloy. Aluminum alloy has good thermal conductivity and can effectively improve the heat dissipation effect. The first connecting plate 25 and the second connecting plate 311 have the same specifications and are symmetrically arranged. That is, the outer holes of the first connecting plate 25 and the second connecting plate 311 correspond one-to-one. The two can be detachably fixedly connected by bolts, which facilitates quick assembly and disassembly and ensures the stability of power transmission.

[0026] A wear-resistant bushing is provided between the sliding sleeve 32 and the slide rail 31 to reduce wear between the sliding sleeve 32 and the slide rail 31 and extend service life. The sliding sleeve 32 is equipped with a locking component for position locking. After the sliding sleeve 32 slides to the appropriate position, it is fixed by the locking component to ensure the stability of the mounting tray 34.

[0027] The mounting tray 34 and the connecting frame 33 are fixed by welding or bolting to ensure the connection is firm and adapt to different installation needs and scenarios.

[0028] The top surface of the mounting tray 34 is provided with anti-slip grooves 37. There are multiple anti-slip grooves 37, and the multiple anti-slip grooves 37 are distributed in parallel and spaced order on the top surface of the mounting tray 34. This can increase the friction between the reducer and the mounting tray 34, prevent the reducer from slipping during the test, and improve the installation stability.

[0029] There are two balance bearings 39, which are fixedly installed in two balance supports 38 respectively. They can jointly form a rotational support for the transmission shaft 310, ensuring the coaxiality and stability of the transmission shaft 310 during rotation, thereby improving the accuracy of power transmission.

[0030] The working principle of this utility model is as follows: In use, according to the specifications of the reducer to be tested, the position of the sliding sleeve 32 on the slide rail 31 is adjusted, and the distance between the mounting tray 34 and the test component 2 is adjusted. The position of the sliding sleeve 32 is then locked using the locking component. The reducer to be tested is placed on the mounting tray 34, and the reducer is fixed with bolts through the waist-shaped hole 36 on the side plate 35. The input or output end of the reducer is connected to the connecting seat 312 of the transmission shaft 310 through the connecting hole 313. Then, the first connecting plate 25 and the second connecting plate 311 are connected and fixed with bolts. The test host 21 is started, and the test host 21 drives the transmission shaft 310 to rotate through the test shaft 24, the first connecting plate 25, and the second connecting plate 311, thereby driving the reducer to be tested to run. During the test, the working heat of the test host 21 is quickly dissipated through the heat dissipation fins 23 on the outer shell 22. The data processing host 26 collects the operating data of the test host 21 in real time through the data cable 28, and displays and processes it on the control panel 27, thereby completing the test of the reducer.
