[0029] An embodiment of this utility model provides a motor torque testing device, such as... Figure 1-5 As shown, it includes:

[0030] Mounting plate 100 is used to fix the motor under test;

[0031] The counterweight device 200 includes a plurality of counterweight elements 210 with preset weights. The counterweight device 200 can adjust the number of counterweight elements 210 to adjust the actual output weight.

[0032] The motor connection assembly 300 has one end connected to the output shaft of the motor under test and the other end connected to the counterweight device 200.

[0033] Mounting plate 100 is used to fix the motor under test. The design of mounting plate 100 ensures the stability of the motor during testing, preventing inaccurate test results due to vibration or displacement. Mounting plate 100 may have multiple fixing points or clamps to accommodate motors of different sizes and types. Counterweight device 200 includes several counterweight elements 210 with preset weights. These elements can be added or removed according to test requirements to adjust the actual output weight. The design of the counterweight elements 210 should ensure accurate weight for quick adjustment of test conditions. Counterweight device 200 may include a support structure for suspending or supporting the counterweight elements 210, ensuring that their weight is effectively transmitted to the motor output shaft. Motor connection assembly 300 is used to connect the output shaft of the motor under test and the counterweight device 200. It can withstand the weight applied by the counterweight device 200 and ensures efficient and accurate torque transmission. The connection element may include couplings, drive belts, or other mechanical connections, depending on the type of motor and test requirements.

[0034] The working principle of this utility model is as follows:

[0035] During the testing process, the motor under test is first fixed on the mounting plate 100, and then the motor output shaft is connected to the counterweight device 200 via the motor connection assembly 300. Then, according to the testing requirements, the number of counterweight elements 210 on the counterweight device 200 is adjusted to apply different weights. The output shaft of the motor under test is connected to the counterweight device 200 via the motor connection assembly 300. The motor is started, and the weight it can drive is observed and recorded to determine the motor's torque. This invention can accurately test the torque of a motor by adjusting the weight of the counterweight device 200. This testing device is of great significance for motor research and development, quality control, and performance evaluation.

[0036] In some embodiments, a plurality of counterweight elements 210 are stacked in the vertical direction, and the counterweight device 200 further includes a selection structure 220 for selecting the counterweight elements 210.

[0037] Multiple counterweight elements 210 are stacked vertically. This design allows for adjustment of the weight applied to the motor output shaft by simply selecting the number of counterweight elements 210. The counterweight device 200 also includes a selection structure 220 for selecting the counterweight elements 210, which allows for selection from top to bottom to change the weight. The selection structure 220 is designed to facilitate the operator's selection and securing of the required number of counterweight elements 210. The selection structure 220 may include hooks, slots, or other mechanical devices for securing the selected counterweight elements 210, ensuring they do not accidentally fall off during testing. Each counterweight element 210 may be marked with its weight to allow the operator to quickly identify and select the appropriate counterweight element 210. During testing, if the applied weight needs to be adjusted, the operator can quickly increase or decrease the number of counterweight elements 210 using the selection structure 220. This design allows for dynamic adjustments during testing to accommodate different testing requirements.

[0038] Furthermore, the selected structure 220 includes a fixed frame 230, and the counterweight element 210 is movably mounted on the fixed frame 230 and can move in the vertical direction.

[0039] The mounting bracket 230 is used to support and position the counterweight element 210. The design of the mounting bracket 230 should ensure its structural strength and stability. The mounting bracket 230 may include vertical guide rails or rods along which the counterweight element 210 can move vertically. The counterweight element 210 is designed to be movably mounted on the mounting bracket 230, meaning that the counterweight element 210 can move freely on the mounting bracket 230. Vertical movement of the counterweight element 210 can be achieved through various mechanisms, such as sliding or guide rail systems. These mechanisms should be designed to be both flexible and stable to ensure that the counterweight element 210 does not jam or shift during movement.

[0040] Furthermore, the counterweight element 210 is provided with a vertical through hole 240 and a selection groove 250 perpendicular to the through hole 240. The selection structure 220 also includes a selection rod 260 with one end passing through the through hole 240 and a selection bar 280 cooperating with the selection rod 260. The other end of the selection rod 260 is connected to the motor connection assembly 300. The selection rod 260 is provided with a selection hole 270 that can be connected with the selection groove 250. The selection bar 280 can pass through the selection groove 250 and be inserted into the selection hole 270.

[0041] Each counterweight element 210 has a vertical through-hole 240 for accommodating a selection rod 260. The counterweight element 210 also has a selection slot 250 perpendicular to the through-hole 240, which allows a selection rod 280 to pass through and be inserted into a selection hole 270 to fix the position of the counterweight element 210. One end of the selection rod 260 is designed to pass through the through-hole 240 of the counterweight element 210, allowing the selection rod 260 to pass through multiple stacked counterweight elements 210. The other end of the selection rod 260 is connected to the motor connection assembly 300 to ensure that the weight applied by the counterweight element 210 is effectively transmitted to the motor output shaft. The selection rod 260 has selection holes 270 that mate with the selection slot 250 for engaging with the selection rod 280. The selection rod 280 can pass through the selection slot 250 of the counterweight element 210 and be inserted into the selection hole 270 to select the number of counterweight elements 210. This design allows the operator to select and fix a specific number of counterweight elements 210 as needed.

[0042] During operation: The operator first inserts the selection rod 260 from top to bottom into the through hole 240 of the stacked counterweight elements 210. Then, the operator inserts the selection bar 280 through the selection slot 250 of the counterweight element 210 and into the selection hole 270 on the selection rod 260 to select the number of counterweight elements 210. When the selection rod 260 moves upward, the counterweight elements 210 above the selection bar 280 are simultaneously driven upward. During testing, if it is necessary to adjust the applied weight, the operator can pull out the selection bar 280 and then reinsert it into another selection hole 270 to fix the new counterweight setting. By inserting the selection bar 280 into different selection holes 270, different numbers of counterweight elements 210 can be driven to achieve different output weights.

[0043] In some embodiments, the motor connection assembly 300 includes a connection line 360 ​​and a motor connection element. The motor connection element includes a motor connection portion 320 connected to the output shaft of the motor under test and a counterweight connection portion 310 connected to one end of the connection line 360. The other end of the connection line 360 ​​is connected to the counterweight device 200.

[0044] The motor connection 320 is used to connect to the output shaft of the motor under test, ensuring that the motor's output can be effectively transmitted to the counterweight device 200. The motor connection 320 can employ a coupling, clamp, or other connection method to ensure the stability and reliability of the connection. This connection may also include an anti-slip design to prevent the motor from slipping or loosening when torque is applied. The counterweight connection 310 is connected to the counterweight device 200 via a connecting line 360, enabling the motor's torque to be effectively transmitted from the motor to the counterweight device 200. The material and structure of the connection should be able to withstand the applied torque, preventing deformation or damage during testing. A torque sensor can be installed in the connection to monitor the applied torque in real time, thereby improving the accuracy and reliability of the test.

[0045] Furthermore, the motor connection part 320 includes a connector 330 that mates with the output shaft of the motor under test, and the connector 330 is provided with a fastening structure 340 for fixing the output shaft of the motor under test.

[0046] The motor connection 320 includes a connector 330 that mates with the output shaft of the motor under test. The connector 330 is designed to match the size and shape of the motor output shaft for a tight connection. The material and structure of the connector 330 should be able to withstand applied torque to prevent deformation or damage during testing. The connector 330 has a fastening structure 340 for securing the output shaft of the motor under test. This fastening structure 340 is designed to ensure the stability of the motor output shaft during testing, preventing displacement due to vibration or torque. The fastening structure 340 can take various forms, such as screws, snap rings, lock nuts, or other mechanical fasteners 350.

[0047] Furthermore, the fastening structure 340 includes a fastener 350 surrounding the connector 330, the fastener 350 being used to secure the output shaft of the motor under test in the connector 330.

[0048] The fastening structure 340 includes fasteners 350 surrounding the connector 330. The fasteners 350 are designed to effectively clamp the output shaft of the motor under test and prevent displacement or loosening during testing. The fasteners 350 can take various forms, such as abutting the motor output shaft with bolts passing through holes in the connector 330, or securing the motor output shaft with multiple bolts surrounding the connector 330.

[0049] In some embodiments, there are two motor connection portions 320, which are respectively disposed at both ends of the counterweight connection portion 310.

[0050] Each end of the counterweight connection part 310 is provided with a motor connection part 320. Since the motor under test is fixed on the mounting plate 100, after testing one motor, another motor can be directly connected to the other motor for testing using the other motor connection part 320, reducing the waiting time for disassembling and assembling the motor and the mounting plate 100 and improving testing efficiency.

[0051] In some embodiments, the counterweight connection 310 is cylindrical.

[0052] The counterweight connection 310 is designed in a cylindrical shape, which helps to simplify the manufacturing process and provides a uniform force distribution surface. Moreover, when testing the torque of the motor, the connecting wire 360 ​​can be wound around the counterweight connection 310.

[0053] Furthermore, it also includes a first pulley 400, and a connecting line 360 ​​fixed to the counterweight connection part 310 can bypass the first pulley 400 and connect to the counterweight device 200.

[0054] The primary function of the first pulley 400 is to guide and support the connecting line 360, enabling it to bypass the pulley and connect to the counterweight device 200. The pulley reduces friction in the connecting line 360 ​​during torque transmission, improving system efficiency and reliability. The connecting line 360 ​​originates from the counterweight connection part 310, bypasses the first pulley 400, and then connects to the counterweight device 200. This winding method alters the direction of force, making the force applied by the counterweight device 200 more direct and effective.

[0055] Furthermore, a second pulley 500 is provided between the counterweight connection part 310 and the first pulley 400, and the second pulley 500 is used to guide the direction of the connecting line 360.

[0056] The main function of the second pulley 500 is to guide the direction of the connecting line 360, ensuring that the connecting line 360 ​​can be transmitted from the counterweight connection part 310 to the first pulley 400 along a predetermined path, and then connected to the counterweight device 200. By guiding the direction of the connecting line 360, the second pulley 500 helps to reduce friction and wear of the connecting line 360, thereby improving the efficiency and reliability of the system.
