Research On Transmission Performance Experimental Test Of New Types Of Filtering Driving Mechanism With Small Tooth Difference Based On VC++

The mission of this paper comes from the key project of National Natural Science Foundation of China-theories and methods of reliability design of the new high performances transmission parts and systems(Project No, 50735008). Aiming at key and common technical problem between harmonic reducer ,RV reducer and turbine and worm reducer in the special and extreme environment of home and abroad,this paper does research on the experimental measurement system of transmissions performances of solid lubricating filtering driving mechanism which is invented by Wang Jiaxu the professor of The State Key Laboratory of Mechanical Transmission (application numbers of invention patent: 200710135602.8).An electro-mechanical and intelligent test-bed was developed to test the transmission performance of filtering driving mechanism. Emphases were put on errors'accuracy analysis of the test system's forward channel, transmission error analysis by spatial domain method and optimization of efficiency. The specific contents are as follows:â‘ At first this paper introduces the structure of new types of filtering driving mechanism with small tooth difference with the core of filtering reducer. And based the introduction, we develop direct current electric power mechanical transmission test bed which is used to test the transmission performance and the power of filtering driving mechanism. The test bed contains the equipment of industrial control computer,motion controlling cards,servo-motor,torque sensor and so on.â‘¡This paper analyses the influence of the test results caused by forwarding channel errors of testing system and the errors of installing and debugging the test bed. Meanwhile, this paper uses a method of data fitting so as to improve measurement accuracy.â‘¢This paper advances method of spatial domain to analyse the integrated transmission errors of the whole transmissions chains of experimental table, and this lays a good foundation for the further development of high precision experimental test platforms. And that ,based on the traditional efficiency experiments this paper optimize the efficiency experiments.â‘£The technology of servo control system, dynamic link library, speed torque sensor, VC + + serial communications related to the above scheme is researched and analyzed. This paper empolder visual and intelligentized experimental operating system with friendly interface basing language of visual C++ 6.0. So make the control system intelligent ultimately.
