However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] See also Figure 1The transmission structure of a servo system test device in one embodiment includes a motor under test 10, a loading motor 20, a detector 30, a coupling, and a first transmission shaft 50. The coupling includes a first coupling 40, a second coupling 41, and a third coupling 42. The first coupling 40 is used to connect the detector 30 to the output shaft of the motor under test 10, the second coupling 41 is used to connect the detector 30 to one end of the first transmission shaft 50, and the third coupling 42 is used to connect the loading motor 20 to the other end of the first transmission shaft 50.

[0034] In the transmission structure of the servo system test device described above, the detector 30 is connected to the output shaft of the motor under test 10, and a coupling is used to detachably connect the first transmission shaft 50 between the detector 30 and the loading motor 20. This allows for replacement of different types of first transmission shafts 50 according to actual testing requirements to meet different test conditions. Because the transmission structure of the servo system test device is provided with the first transmission shaft 50, the motor under test 10 can be placed in a temperature and humidity chamber 94. The first transmission shaft 50 passes through the mounting hole of the temperature and humidity chamber 94 and extends outside the temperature and humidity chamber 94 to connect to the loading motor 20 to meet the testing requirements of the temperature and humidity chamber 94. The transmission structure of the servo system test device is capable of testing multiple transmission performances, and its testing functions are highly comprehensive.

[0035] Specifically, the above-mentioned first transmission shaft 50 can be a coupling rod, a flexible shaft or a universal transmission rod. By replacing different types of first transmission shafts 50 to meet the requirements of different test conditions, the transmission structure of the servo system test device can be equipped with multiple transmission performance tests. Normally, a coupling rod is used to perform TN characteristic curve test and maximum operating speed test of the motor 10 under test. Of course, the first transmission shaft 50 can also be a flexible shaft, and the motor 10 under test is placed on the vibration table 95 to perform an overspeed test on the motor 10 under test, which can reduce the workload of the coupling. In addition, the first transmission shaft 50 can also be a universal transmission rod, and the motor 10 under test is placed on the vibration table 95 (see Figure 7 ) to perform a maximum operating speed test on the motor 10 under test.

[0036] In one embodiment, the detector 30 is a torque sensor, which is connected to the output shaft of the motor under test 10 using a first coupling 40 to measure and collect parameters such as torque and speed of the motor under test 10. Of course, other types of sensors may be installed on the output shaft of the motor under test 10 according to actual testing requirements, and the present invention is not limited to this.

[0037] In one embodiment, see Figure 1 、 Figure 3 、 Figure 5 and Figure 6The transmission structure of the servo system test device further includes a support frame, which includes a first support frame 60 and a second support frame 61. The first support frame 60 is provided between the detector 30 and the first transmission shaft 50, and the second support frame 61 is provided between the first transmission shaft 50 and the loading motor 20. The provision of the first support frame 60 and the second support frame 61 can improve the stability and positioning accuracy of the first transmission shaft 50.

[0038] Specifically, see Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 A second transmission shaft 51 is provided between the detector 30 and the first transmission shaft 50, a bearing ring adapted to the second transmission shaft 51 is provided on the first support frame 60, the second transmission shaft 51 passes through the bearing ring on the first support frame 60, and is connected between the first transmission shaft 50 and the detector 30. A third transmission shaft 52 is provided between the first transmission shaft 50 and the loading motor 20, a bearing ring adapted to the third transmission shaft 52 is provided on the second support frame 61, the third transmission shaft 52 passes through the bearing ring on the second support frame 61, and is connected between the first transmission shaft 50 and the loading motor 20. In this embodiment, two first support frames 60 and two second support frames 61 are provided respectively, and a bearing ring is provided on each of the two first support frames 60 and the two second support frames 61. The bearing rings on the two first support frames 60 are independently detachable structures, and similarly, the bearing rings on the two second support frames 61 are also independently detachable structures. The second transmission shaft 51 passes through the bearing rings of the two first support frames 60, and the third transmission shaft 52 passes through the bearing rings of the two second support frames 61, so as to further improve the stability and positioning accuracy of the first transmission shaft 50. Of course, the number of the first support frames 60 and the second support frames 61 can be set according to actual needs. For example, one, three or more first support frames 60 and second support frames 61 can be provided, but the present invention is not limited thereto.

[0039] Further, see Figure 1 and Figure 4 The coupling further includes a fourth coupling 43 and a fifth coupling 44. The fourth coupling 43 is used to connect one end of the second transmission shaft 51 to the detector 30, and the other end of the second transmission shaft 51 to one end of the first transmission shaft 50. Similarly, the fifth coupling 44 is used to connect one end of the third transmission shaft 52 to the other end of the first transmission shaft 50, and the other end of the third transmission shaft 52 to the output shaft of the loading motor 20.

[0040] The above-mentioned couplings are all elastic couplings. Specifically, the coupling includes two halves, and the ends of the two halves are connected by a cross-shaped bayonet with staggered teeth, and the shafts at both ends of the coupling are connected by the cross-shaped bayonet. An elastic block is provided between the two halves of the elastic coupling, and the elastic block serves as a contact point to achieve the separation and fit of the two halves. At the same time, during the vibration test, the elastic compensation of the elastic coupling can reduce the radial error and angular error between the tested motor 10, the detector 30, the first transmission shaft 50 and the loading motor 20, thereby improving the test accuracy of the servo system. In addition, the elastic block in the elastic coupling can also play the role of buffering, anti-vibration, vibration suppression, heat insulation and the like.

[0041] Further, see Figure 1 、 Figure 4 and Figure 7 The transmission structure of the servo system test device also includes a slide and a base. The slide includes a first slide 70 and a second slide 71, and the base includes a first base 80 and a second base 81.

The second base 81 is arranged on the second slide 71, and the loading motor 20 is located on the second base 81. Specifically, the above-mentioned first slide 70 is used to be arranged on a vibration table 95, which is convenient for performing vibration testing on the motor under test 10. In addition, the first slide 70 can also be placed in a temperature and humidity chamber 94 to facilitate the temperature and humidity chamber 94 test on the motor under test 10.

[0042] In one embodiment, see Figure 1 、 Figure 3 and Figure 5 , the transmission structure of the servo system test device also includes a first fixed frame 62, and the motor 10 under test is arranged on the first fixed frame 62. A first slide slot hole 621 is provided on the first fixed frame 62, and a first fastener 622 is inserted into the first slide slot hole 621, and the first fastener 622 is connected to the first base 80. Since the first fastener 622 is inserted into the first slide slot hole 621 of the first fixed frame 62, under the action of force, the first fixed frame 62 can move on the first base 80 to adjust the position of the first fixed frame 62. Specifically, the above-mentioned first slide slot hole 621 is a rounded rectangular screw hole, and the rounded rectangular screw hole is adapted to the first fastener 622. In this embodiment, the first slide slot hole 621 is longitudinally arranged on the first fixed frame 62, so that the first fixed frame 62 can move along the width direction of the first base 80 (the above-mentioned width direction is Figure 3 The first slide hole 621 can also be arranged horizontally on the first fixing frame 62, so that the first fixing frame 62 can move along the length direction of the first base 80 (the length direction is Figure 3X-axis direction) to achieve adjustment of the first fixing bracket 62 in the X-axis direction.

[0043] In this embodiment, the first fixing frame 62 is provided with six first slide slot holes 621, three of which are spaced apart on one side of the first fixing frame 62, and the other three are spaced apart on the other side of the first fixing frame 62.

The first slider slides in the first slide groove 810 to adjust the position of the first fixing frame 62. After the first fixing frame 62 is adjusted to a suitable position, the first slider is fixed to the first base 80 by the first fastener 622 to prevent the first slider from sliding during the test and affecting the test effect. Specifically, the first slide groove 810 can be provided along the length direction or width direction of the first base 80 (the length direction is Figure 3 In the X-axis direction, the width direction is Figure 3 In the Y-axis direction, for example, the first slide groove 810 is provided along the length of the first base 80, and the first slide groove hole 621 is provided along the width of the first fixing frame 62; alternatively, the first slide groove 810 is provided along the width of the first base 80, and the first slide groove hole 621 is provided along the length of the first fixing frame 62.

[0045] Specifically, the width of the bottom of the first chute 810 is greater than the width of the top of the first chute 810, and the side cross-section of the first base 80 is convex. The first slider is arranged at the bottom of the first chute 810 to prevent the first slider from slipping off the top of the first chute 810.

[0046] Further, see Figure 1 and Figure 5 The first support frame 60 and the detector 30 are both arranged on the first base 80. The first support frame 60 and the detector 30 are also provided with a first slide slot hole 621.

Specifically, the above-mentioned second slide slot hole 631 is a rounded rectangular screw hole, and the rounded rectangular screw hole is adapted to the second fastener 632. In this embodiment, the second slide slot hole 631 is longitudinally arranged on the second fixed frame 63, so that the second fixed frame 63 can move along the width direction of the second base 81 (the above-mentioned width direction is Figure 3 Of course, the second slide hole 631 can also be set horizontally on the second fixing frame 63, so that the second fixing frame 63 can move along the length direction of the second base 81 (the length direction is Figure 3 x-axis direction) to achieve adjustment of the second fixing bracket 63 in the x-axis direction.

By rotating the handwheel 813, the second base 81 can be made to slide along the guide rail, thereby adjusting the position of the second fixed frame 63 and the second support frame 61 on the second base 81. In addition, since a coupling is used to connect the loading motor 20 and the third transmission shaft 52, the loading and separation of the loading motor 20 can be completed quickly to meet different testing requirements.
