Parametric Design For Swing Movable Teeth Transmission Mechanism

Swing movable teeth transmission,which is used to transmit rotary motion and power between two shafts with the same axis.It has advantages of multi-teeth meshing,strong load-carrying capacity,high transmission efficiency, large range transmission ratio etc.These characteristics make it has a very good applicative prospects.With the rapid development of science and technology, engineering designers with parametric technology,can greatly improve the only geometry dimension in order to change the design efficiency and avoid parts of the repeated work trivial.Till now,parametric technology has become an important research in CAD.According to equivalent mechanism of swing movable teeth transmission, the paper analyze the structure and work principle of swing movable teeth transmission;Establish bearing model of the swing movable teeth transmission, work out stress calculation formula for meshing pair of swing movable teeth transmission,and analyze the moving state of swing movable teeth transmission and parameters on the influence of center teeth profile.According to the development software and programming language, determine the characteristics of the secondary development platform and tools, analyze the main use of SolidWorks interface object function and user interface design principles.Use Visual Basic programming to realize key-module design parameterization and generate engineering drawing,analyze the conditions of its teeth profile donot happened top cut.Establish swing movable teeth transmission mechanism, complete the entity model of SolidWorks and ADAMS between interface and successfully transform the two geometric model;Then define the movement between the various components vice,impose constraints and load.To carry on motion simulation for swing movable teeth transmission mechanism;Through the motion simulation of swing movable teeth transmission mechanism,analyze the movement characteristics and the load situation of the key parts.
