[0019] The worm gear reducer experimental device includes a base 2 and an experimental component 1. The base 2 is equipped with multiple groups of experimental components 1 (see the appendix of the manual). Figure 1 and 2 ).

[0020] The experimental assembly 1 includes a workpiece holder 3, a load motor 4, a load connection assembly 6, an input connection assembly 16 and an angle control assembly 10 (see the appendix of the manual). Figure 2 ).

[0021] During operation, the workpiece to be tested (worm gear reducer) can be fixed on the workpiece clamp 3. A load motor 4 is installed on the machine base 2 at one end of the workpiece clamp 3; a load connection component 6 is installed between the load motor 4 and the workpiece clamp 3 through a bearing seat 5 (see the appendix of the manual). Figure 2 ).

[0022] The load connection assembly 6 includes a transmission shaft 17, a universal coupling 18, a transmission sleeve 19, a sliding spline rod 20 and a connector 21; the transmission shaft 17 is mounted on the machine base 2 through the bearing seat 5; one end of the transmission shaft 17 is connected to the load motor 4 through the torque sensor 7; the other end of the transmission shaft 17 is mounted with a transmission sleeve 19 through the universal coupling 18; the sliding spline rod 20 is mounted in the transmission sleeve 19 through a spline groove; one end of the sliding spline rod 20 is connected to the connector 21.

[0023] The connector 21 includes a connecting fork 26, a cross shaft 27 and a connecting fork 28; one end of the connecting fork 26 is provided with a connecting fork 28 through the cross shaft 27; the interior of the connecting fork 28 is provided with a connecting groove (see the appendix of the manual). Figure 2 and 5During operation, the connecting fork 28 on the load connection assembly 6 is connected to the output end of the workpiece (worm gear reducer). When the output end of the workpiece (worm gear reducer) rotates, it can drive the torque sensor 7 to rotate through the connecting head 21, sliding spline rod 20, transmission sleeve 19 and transmission shaft 17. During this process, the load motor 4 can provide load torque to the workpiece (worm gear reducer).

[0024] The purpose of setting up the load connection assembly 6 in this way is to make it possible to change the length of the load connection assembly 6 during operation by utilizing the characteristic that the sliding spline rod 20 can move relative to the transmission sleeve 19; and to change the angle of the connector 21 by setting up the universal coupling 18, so as to achieve the purpose of connecting the output ends of various types of workpieces (worm gear reducers) through the load connection assembly 6.

[0025] A swing frame 9 is mounted on the machine base 2 inside the workpiece clamp 3 via a rotating shaft 8; one side of the swing frame 9 is connected to the machine base 2 via an angle control component 10 (see the appendix of the manual). Figure 4 ).

[0026] The angle control assembly 10 includes an adjusting screw A29, an adjusting screw B30 and a control sleeve 25; the adjusting screw A29 is hingedly connected to one side of the swing frame 9; the adjusting screw B30 is hingedly connected to the machine base 2 on one side of the adjusting screw A29; the adjusting screw A29 and the adjusting screw B30 are connected to each other through the control sleeve 25; when the control sleeve 25 rotates forward, the adjusting screw A29 and the adjusting screw B30 move closer to each other; when the control sleeve 25 rotates backward, the adjusting screw A29 and the adjusting screw B30 separate from each other (see the appendix of the instruction manual). Figure 4 ).

[0027] The purpose of providing the angle control assembly 10 in this way is to drive the swing frame 9 to rotate by adjusting the overall strength of the angle control assembly 10 by rotating the control sleeve 25, thereby achieving the purpose of adjusting the swing frame 9 to a suitable angle.

[0028] A longitudinal slide 12 is mounted on the swing frame 9 via a longitudinal screw mechanism 11; a lifting slide 14 is mounted on the longitudinal slide 12 via a vertical screw mechanism 13; and a drive motor 15 is mounted on the lifting slide 14. During operation, the position of the lifting slide 14 can be adjusted by the longitudinal screw mechanism 11, the vertical screw mechanism 13, and the longitudinal slide 12.

[0029] The lifting slide 14 below the driving motor 15 is provided with an input connection assembly 16 (see the appendix of the manual) through the bearing seat 5. Figure 2 ).

[0030] The input connection assembly 16 includes an input shaft 22, a universal coupling 18, an input sleeve 23 and a spline sliding shaft 24; the input shaft 22 is mounted on the lifting slide 14 through the bearing seat 5; the input shaft 22 is connected to the drive motor 15 through the torque sensor 7; the lower end of the input shaft 22 is mounted with the input sleeve 23 through the universal coupling 18; the spline sliding shaft 24 is mounted in the input sleeve 23 through the spline groove; the lower end of the spline sliding shaft 24 is mounted with a connector 21 (see the appendix of the specification) Figure 2 and 6 ).

[0031] The connector 21 includes a connecting fork 26, a cross shaft 27 and a connecting fork 28; one end of the connecting fork 26 is provided with a connecting fork 28 through the cross shaft 27; the interior of the connecting fork 28 is provided with a connecting groove (see the appendix of the manual). Figure 2 and 6 ).

[0032] During operation, the input connection component 16 can be connected to the input end of the workpiece (worm gear reducer) through the connecting fork 28. In this way, when the drive motor 15 is working, the input end of the workpiece (worm gear reducer) can be driven to rotate through the input connection component 16 and the connecting head 21.

[0033] The purpose of configuring the input connection assembly 16 in this manner is to adjust the length of the input connection assembly 16 by sliding the splined sliding shaft 24 through the spline groove within the input sleeve 23. Furthermore, the input connection assembly 16 can also adapt to the input end of various worm gear reducers by adjusting the angle of the connector 21 via the universal coupling 18.

[0034] When the worm gear reducer experimental device is operating, the drive motor 15 rotates the input end of the workpiece (worm gear reducer) via the input connection assembly 16 and the adapter 21. The load motor 4 provides load torque to the workpiece (worm gear reducer) via the load connection assembly 6. This experimental device simulates the working conditions of the workpiece (worm gear reducer), allowing the parameters of the drive motor 15 and load motor 4 to be adjusted as needed for further experimentation. After the experiment is completed, a new workpiece can be replaced to begin the next operating cycle.

[0035] The worm gear reducer test device has a compact structure and ingenious design. It can be adjusted according to the model of the workpiece, so that it can adapt to the needs of testing and using various types of worm gear reducers, thereby solving the problem of a single experimental model in existing worm gear reducer testing methods, and is particularly suitable for the needs of worm gear reducer testing.
