[0046] The controller 14 is communicatively connected to the drive unit 1, the input tilt sensor 10, the first output tilt sensor 11, and the second output tilt sensor 12 (including but not limited to wire connection and wireless connection).

[0047] As some embodiments of this application, applying the testing device to perform performance testing on the transmission system 13 under test may include: testing the transmission clearance of the transmission system 13 under test, and the testing process is as follows:

[0048] The controller 14 controls the drive unit 1 to perform linear loading with a first loading torque and a first loading slope. The first loading torque can be in the range of 0 N / m to 50 N / m.

[0049] The torsion angle ∠ of the input shaft is obtained through the input tilt sensor 10, the first output tilt sensor 11, and the second output tilt sensor 12. {in1}, Torsion angle ∠ of the first output shaft {out1}, Torsion angle ∠ of the second output shaft {out2}, and calculate the relative clearance value of the transmission system 13 under test at this time. ;

[0050] The controller 14 controls the drive unit 1 to perform linear loading with a second loading torque and a second loading slope. The second loading torque can be in the range of 0 N / m to 50 N / m.

[0051] The torsion angle ∠ of the input shaft is obtained through the input tilt sensor 10, the first output tilt sensor 11, and the second output tilt sensor 12. {in2}, Torsion angle ∠ of the first output shaft {out3}, Torsion angle ∠ of the second output shaft {out4}, and calculate the relative clearance value of the transmission system 13 under test at this time. ;

[0052] according to , Calculate the transmission clearance of the transmission system 13 to be tested.

[0053] Therefore, it is possible to accurately measure the rotational torque and torsional angle, and calculate the transmission clearance of the transmission system 13 under test through two relative clearance values, which can improve the measurement accuracy, reduce the dependence on manual labor, increase the degree of automation, and increase the operating efficiency.

[0054] As some embodiments of this application, according to the formula calculate According to the formula calculate Where i is the transmission ratio of the transmission system 13 under test. This allows for the accurate calculation of the relative clearance value of the transmission system 13 under test. , This improves the accuracy of obtaining the relative clearance value, thereby improving the measurement accuracy of the transmission clearance of the transmission system 13 under test.

[0055] As some embodiments of this application, the controller 14 controls the drive unit 1 to be loaded sequentially with the first preset parameter, the second preset parameter, ..., the Nth preset parameter. The first preset parameter, the second preset parameter, ..., the Nth preset parameter all include: loading torque and loading slope. Vibration points and noise signals are collected by an acoustic sensing acquisition device to evaluate the Clunk level of the transmission system 13 under test.

[0056] According to actual testing requirements, multiple linear loading intervals, i.e., process steps 1 to n, can be set. Each step is operated according to the corresponding loading speed (loading slope) and loading torque, and the data is recorded. Specifically, multiple target torques (T1, T2, T3 to Tn) and corresponding loading and unloading slopes (K1, K2, K3 to Kn) and the duration of the target torque (t1, t2, t3 to tn) can be set to load torque sequentially.

[0057] Furthermore, before the drive unit 1 is loaded sequentially with the first preset parameter, the second preset parameter, ..., the Nth preset parameter by the controller 14, an acoustic sensing acquisition device is set up. During the loading process, the acoustic sensing acquisition device collects vibration points and noise signals to accurately assess the Clunk level of the transmission system 13 under test. This allows for the timely detection of potential faults, rapid location of vibration points in the transmission system 13 under test, and guidance for optimizing materials and production processes.

This setting can reduce the influence of the data previously collected by the input tilt sensor 10, the first output tilt sensor 11, and the second output tilt sensor 12 on the current test, which is beneficial to improving the accuracy of the test.

It transmits this torque to the controller 14, allowing the controller 14 to detect it and control the output torque of the drive component 1 based on this torque, thus achieving closed-loop control and improving testing accuracy.

[0063] In some embodiments of the present invention, such as Figure 3 As shown, the testing device also includes an A / D conversion module 15, which is communicatively connected to the torque measuring instrument 4 and the controller 14. The A / D conversion module is mainly used to convert analog signals into digital signals as inputs to the controller 14, so that the controller 14 can acquire the torque during the rotation or relative motion of the drive shaft 3.

[0066] The control data processing module 17 converts data from the controller 14 into communication codes, serving as a bridge for data interaction with the control and display systems. It can directly access the internal variable names of the controller 14 via EtherNet / IP tag communication. The motion data processing module 18 converts bus motion control data into EtherCAT protocol data, enabling rapid data exchange with the servo drive control unit of the drive unit 1. The sensor data processing module 19 primarily processes the Modbus-RTU protocol data converted from the real-time input tilt sensor 10, the first output tilt sensor 11, and the second output tilt sensor 12 before transmitting it to the controller 14.

[0067] In some embodiments of the present invention, such as Figure 3As shown, the testing device also includes an I / O conversion module 16. The I / O conversion module 16 is mainly used to convert high-voltage digital quantities into low voltage quantities as the operational control input of the controller 14. The I / O conversion module 16 can detect the change in voltage state in the circuit after the emergency stop switch is triggered. After this change is detected by the I / O conversion module 16, the corresponding control logic is triggered to realize the shutdown of the equipment.
