Basic Performance Analysis And Parameter Synthesis Of Non-frictional Step-less Generator

At present, mechanical impulse stepless speed regulators are applied extensively. Because the structures of those regulators existing at present have a lot of advantages and disadvantages, it affects their application in the cases that small impulse output and stability are required.This paper presents an original non-frictional and sequential operation's stepless speed regulator on the basis of overview of the main weakness of impulse stepless speed regulators. Basing on the requirement of the project supported by Chongqing Science and Technology Committee, the Study and Development on Original Non-frictional and Sequential Operation's Stepless Speed Regulator, the author has made some analysis to the physical principle and speed adjustment principle. In addition, as the main part of stepless speed regulators, the transformer was more concerned in the study. After probing the creation of its structure principle, this paper reveals its structure and dynamics rule, and creates a dynamics model and synthesis model of transformer. Furthermore, it was the first time to make a systemic analysis and study to the motion rule and affected factors of this kind of transformer. With the applications of relative polar method and equal view angle method, the transformer that satisfies the requirement of transmission rate and output motion is synthesized. Thus, an original non-frictional stepless speed regulator with a 1.5KW input power, a 1500 rotation speed, a constant150output rotation speed and a maximum 300 output rotation speed was achieved. Its size has been optimized with the software Adams. Finally, the over-constraint study to this original non-frictional stepless speed regulator was carried out and a configuration project of its zero over-constraint motion pair was obtained.The theme in the paper is to key parts of project of the Study and Development on Original Non-frictional and Sequential Operation's Stepless Speed Regulator, which is supported by Chongqing Municipal Science and Technology Committee Schedule projects, it will make good foundation in relative technology research domains.
