Parametric Modelling of Standard & Modified Spur Gear Using Pro-E & Analysing It by Actual Model

Authors(1) :-Dharini Trivedi

Modification and atomization parameters for spur gears is technique to generate the series of same kind of model having different dimensions using standard models like PRO-E, CATIA etc. also it helpful to analyze the results with actual model. Vibration induced by gears includes important data about gearbox condition. Dynamic modeling of gear vibration used for increasing information about vibration generating mechanisms in gearboxes and dynamic behavior of gearbox in the presence of some kind of gear defects. In this paper a six degree-of-freedom nonlinear dynamic model including different gear errors and defects is developed for investigation of effects of tooth localized defect and profile modifications on overall gear dynamics. Interactions between tooth modifications and profile error are studied and the role of profile modification in dynamic response when a localized defect is incurred by a tooth is shown. It is indicated that although profile modifications and profile errors are micro-geometrical, which considerable effects on vibrations of gear pair also. Especially for the case of root relieved teeth that is shown to be more effective in reduction of vibration in the presence of tooth localized defect. Finally, the simulation results are compared with results from literature and the model. This paper introduces a method and steps based on Pro / E parametric drive to forming involute modified spur gear, with the same way to automatically generate model of base circle larger and smaller than root circle, simplify the procedures.
