In other embodiments, the specific structure of the support member can be set as needed, as long as the same technical effect can be achieved, which will not be repeated here. The drive motor 11 and the reducer 14 to be tested are generally connected by a coupling, preferably an elastic coupling 13. It can be understood that the inertial load 15 can be set to multiple, and the weight of each inertial load 15 is different. By applying loads of different weights, the torque size borne by the reducer 14 to be tested is changed to adapt to the test requirements of different reducers 14 to be tested, so as to improve the versatility of the test device; the loading life test is carried out according to the equal acceleration / deceleration curve or the sinusoidal acceleration / deceleration curve until thermal equilibrium or damage.

[0043] The acceleration detection component 16 is specifically an acceleration sensor. The control component 20 is connected to the drive motor 11 and the acceleration detection component 16 respectively to receive test data for storage, or upload to the host computer 24 for data analysis.

[0044] Compared with the prior art, the life test device 100 for a face gear reducer provided in the embodiment of the present application has the following technical effects:

The rotation speed and the swing angle range can be adjusted according to the test requirements. By applying inertial loads 15 of different weights to change the torque size of the reducer 14 to be tested, a loading life test is performed according to an equal acceleration / deceleration curve or a sinusoidal acceleration / deceleration curve.

[0048] The first temperature sensor monitors the temperature of the reducer 14 to be tested. When the temperature value of the first temperature sensor is greater than or equal to the preset temperature value, the control component 20 issues an alarm and shuts down the system, so as to realize unattended autonomous operation around the clock and improve the safety of the system. Similarly, the second temperature sensor monitors the temperature of the drive motor 11. When the temperature of the second temperature sensor is greater than or equal to the preset temperature value, the control component 20 issues an alarm and shuts down the system, so as to further improve the safety of the system.

The operation and monitoring software of the host computer 24 has a networking function, so that the operator can remotely view the actual test status online and control the start and stop of the system. The test device can operate stably and continuously within the set safety threshold. If the temperature exceeds the limit or the tested part fails, the test device will automatically shut down and send the alarm information to the operator by email, realizing the function of unattended and autonomous operation around the clock.
