3D Parametric Modeling of Slewing Bearing

A slewing bearing can be seen as a composite of gear and bearing,and it is complicated to develop a 3D slewing bearing model.It is discussed to develop a parametric modeling method with Pro/PROGRAM.All the features can be hided or unhided,and executed by Pro/PROGRAM.When a parameter table is established by Pro/PROGRAM,a 3D model can be gained just by putting in geometry parameter.
