Study On Geneva Mechanism With Low-pairs And Cad Interface

This academic thesis is designed a kind of machinery on geneva mechanism with low-pairs, through analysis of the movement and structure parameter of geneva mechanism. This machinery solved the problem of geneva mechanism抯 tangent tired intensity in the overload. Comparing with general geneva mechanism, it has the feature of higher bearing capacity, longer service life, and applies to heavy-duty machine. Compared with technological characteristic of all kinds of graph interface in AutoCAD, I focused on study on ActiveX Automation, this is new interface technology in AutoCAD. I studied the Visual Basic program principle based on AutoCAD platform, analyzed the work structure of Windows, work driver module, user and server etc. These are all crucial technologies. I develop the ActiveX Automation interface program successfully in the Visual Basic 5.0 development environment. This interface program has a friendly face, strong graphical functions and easy use, the user needn抰 learn a lot of commands and installations of AutoCAD, only key in the number according to interface program抯 requirement, the program can control AutoCAD automatically, and we can get all kinds of graphs, it is very nice and easy. This interface program already has been proved correct and effective again and again. Adopting this interface program, My thesis give the example of one accessory in the geneva mechanism with low- pairs successfully and automatically.
