Then the load motor stops working, and the drive motor continues to output torque. The power is transmitted to the load motor transmission mechanism through the electromagnetic clutch in the engaged state. At this time, the load motor transmission mechanism is equivalent to the load. The torque at the drive end is measured by the first torque sensor, and the torque at the load end is measured by the second torque sensor. By setting relevant test data such as voltage, current and temperature, the corresponding torque is tested under different relevant test data.

[0018] Since the first and second lead screw transmission mechanisms can drive the drive motor transmission mechanism and the load motor transmission mechanism to move towards the fixed component, the drive motor transmission mechanism and the load motor transmission mechanism are connected to the fixed component respectively, eliminating the need for manual installation of end face teeth and engagement teeth. This has the advantages of high automation, saving labor costs, and improving measurement efficiency. In addition, since the drive motor and the load motor can be adjusted to different speeds, this utility model can measure relevant data of electromagnetic clutches under different working conditions.

[0038] The specific usage process of this utility model is as follows:

[0039] In this invention, the drive motor transmission mechanism and the load motor transmission mechanism are located at opposite ends of the fixed assembly. The drive motor transmission mechanism is connected to the first lead screw mechanism, and the load motor transmission mechanism is connected to the second lead screw mechanism. The electromagnetic actuator is fixed to the fixed assembly, with the end face teeth fixed to the end face teeth fixing assembly and the engagement teeth fixed to the engagement teeth fixing assembly. Then, the first and second lead screw mechanisms are activated. The first lead screw mechanism drives the drive motor transmission mechanism to move towards the fixed assembly, and the second lead screw mechanism drives the load motor transmission mechanism to move towards the fixed assembly, causing the first torque sensor shaft 17a to engage with the first bushing 6 and the second torque sensor shaft 22a to engage with the second bushing 11, until one end of the first slide 28 is located in the first limiting groove 1a and one end of the second slide 34 is located in the second limiting groove 1b. At this point, the fixed assembly is connected to the drive motor transmission mechanism and the load motor respectively. The transmission mechanism is connected, and then the drive motor transmission mechanism and the load motor transmission mechanism are started. The torque output by the drive motor transmission mechanism causes the end face teeth to rotate, and the torque output by the load motor transmission mechanism causes the engagement teeth to rotate. Since there is a speed difference between the drive motor transmission mechanism and the load motor transmission mechanism, there is also a speed difference between the end face teeth and the engagement teeth. Under this condition, the electromagnetic coil of the electromagnetic clutch is energized, so that the end face teeth and the engagement teeth mesh. Then the load motor 19 stops working, and the drive motor 14 continues to output torque. The power is transmitted to the load motor transmission mechanism through the electromagnetic clutch in the engaged state. At this time, the load motor transmission mechanism is equivalent to the load. The torque at the drive end is measured by the first torque sensor 17, and the torque at the load end is measured by the second torque sensor 22. By setting relevant test data such as voltage, current and temperature, the corresponding torque is tested under different relevant test data.

[0040] In addition, by disengaging the electromagnetic clutch and re-engaging it under different voltage, current, and temperature conditions, the electromagnetic clutch can be simulated under different working conditions. This process can be repeated to test the service life of the electromagnetic clutch.
