Gear as the main form of mechanical transmission throughout the machinery industry is one important indicator of the level of industrial technology development , the gear still has an important role in a variety of new technologies to flourish today . Gear had not a single discipline , especially in the application of computers for in-depth study of gear provides an important means , but also put forward a number of new research topics . Meshing analysis mathematical model the plane gear meshing with space set applies to the computer to solve . Including : plane meshing conjugate tooth profile curve , the meshing line , transition curve , sliding coefficient calculation model ; the spiral surface processing principle , the use of rotary tooling spiral surface , according to the known spiral surface and tool rotation surface computational model ; spatial meshing the establishment of the coordinate system and sports relations , known as the first surface curvature and conjugate movement and second surfaces and engages the surface the induced curvature calculation model ; analysis curve unit tangent vector space , the conjugated surface curvature between the principal normal vector , binormal vector , curvature and torsion , the point normal curvature , geodesic curvature and geodesic deflection rate , curved triangular type geometric angular velocity on the surface curves on the surface , the tangential direction of the angular velocity relationship over the main point on the surface curvature and the main direction , induced curvature calculation model . Visual Basic and MATLAB analysis software developed gears . The software the meshing analysis problems involving multiple toothed , variety of tooth profile worm gear meshing , solving and the cutter tooth profile , select Visual Basic as a development tool , the main use of it to create a user interface is easy , concise language , development speed , and good compatibility with other software , the software is the core of scientific computing , the software recognized outstanding scientific computing software MATLAB as a tool , and use COM editor to create a dynamic link Visual Basic and MATLAB , the security of the algorithm port operations and the fact that control , and made ??a detailed introduction to the interface of the two .
