Embodiment 1

[0022] Such as figure 2 As shown, in the test related to bearing capacity, the magnetic powder brake 1 is fastened on the magnetic powder brake support 18, the magnetic powder brake support 18 is fixed on the test platform 19, and the magnetic powder brake 1 is connected with the torque sensor 1 3 through the shaft coupling 1 2 . The torque sensor I 3 is connected to the output end of the harmonic reducer 5 through the coupling II 4. The input end of the harmonic reducer 5 is connected with the connecting shaft 6, and is connected with the torque sensor ΙΙ 8 through the shaft coupling III 7, and the torque sensor ΙΙ 8 is connected with the speed regulating motor 10 through the shaft coupling IV 9. The speed regulating motor 10 is fastened on the motor support 14, and the motor support 14 is fixed on the horizontal slider 13. Described torque sensor ΙΙ 8, harmonic speed reducer 5, torque sensor Ι 3 are respectively fastened with torque sensor support ΙΙ 15, reducer support 1...

Embodiment 2

[0024] Such as image 3 As shown, in the accuracy test, only the torque sensor needs to be replaced by the photoelectric encoder, and the structure of the rest of the device remains unchanged, which can be used for the accuracy test. The specific embodiment is that the photoelectric encoder Ι 20, the photoelectric encoder Ι 23, the photoelectric encoder support Ι 25, and the photoelectric encoder support Ι 24 are respectively fixed on the horizontal slider to form a new slider unit, And get final product that link to each other with corresponding shaft coupling by connecting rod Ι 21, connecting rod Ι 22, other structures are with embodiment 1.

[0025] When the test system is working, the torque sensor collects the torque and speed at the input and output ends of the reducer in real time, and the photoelectric encoder collects the angular displacement at the input and output ends of the reducer in real time, and then transmits the measured data to the industrial computer thro...

Abstract

The invention relates to a comprehensive test system for a harmonic reducer. The comprehensive test system comprises a control system, a loading system and a test system, wherein the control system controls the loading system through transmission of an electric signal; the loading system provides input and output loads for two ends of a test product after receiving an instruction of the control system; and the test system realizes back-passing and feedback of test data through real-time monitoring by a sensor. Through modular designs of all test components, integration of such test contents as running-in test, efficiency test, rigidity test, precision test and life test of the harmonic reducer is realized. The problem that various performance tests of the harmonic reducer need to be performed on different test beds is solved. The comprehensive test system can well meet various test conditions of the product test and truly and accurately test performance indexes of the harmonic reducer, and has the characteristics that simulation of test conditions is more real and the test efficiency is higher.

Description

technical field [0001] The invention relates to a comprehensive test device for testing the performance characteristics of a harmonic reducer, which belongs to the technical field of the harmonic reducer. Background technique [0002] Harmonic gear transmission is widely used in space technology, robot, radar communication, precision optical equipment and medical equipment and other high-precision motion due to its small structure, wide transmission ratio range, multi-teeth meshing, high transmission precision, and strong bearing capacity. control field. [0003] Due to the particularity of the application field of the harmonic reducer, it is necessary to conduct accurate tests and inspections on its multiple performance parameters. Among them, the detection of its carrying capacity and transmission accuracy is particularly important, and it is an important indicator of the quality of the harmonic reducer. The test of bearing capacity mainly includes run-in test, efficienc...
