基于PRO/E的齿轮参数化设计

Gears are widely used in a variety of mechanical transmission of a common parts, used to transfer power to change the speed and direction of rotation. Common are spur gears, helical gears, bevel gear, herringbone gear. This paper introduces based on PRO / E to use Program Gears parametric design approach. According to the principles of involute generation and theoretical formula, equation editor, enter the Cartesian coordinates equation, to generate accurate involute gear teeth, then deflection angle bevel gear according to the parameters of the calculation formula, accurate to create tooth profile curve; the use of mix-and-scanned array command to create a helical gear tooth feature.Allowing designers to easily and quickly achieve the three-dimensional characteristics of gear Design in order to improve design efficiency.
