Dynamics Simulation Analysis Of Multifold-arc Cylinder Gear Based On ADAMs

As a new type of gear mechanism,multifold-arc cylinder gear is one of the arc gears with a transmission performance of point meshing.This paper used the virtual prototype technology to analyze factors of affecting stability of multifold-arc cylinder gear transmission repeatedly.It could avoid the expensive test cost and the waste of materials.The main contents are as follows:Firstly,according to the generating method,the meshing theory of rack and pinion was used for simulated processing to derive the tooth surface equations,and then get the tooth profile of mutiple-arc gear,based on which SolidWorks was used to build 3D solid model.In addition to that,motion process of meshing point was analyzed by the meshing motion of one-to-multi circular arc gear,and in order to establish the theoretical basis of dynamic analysis of multifold-arc cylinder gear,the stress situation of arc gear transmission was also studied.In the following section,the change of meshing stiffness and other basic forms of internal incentive were investigated on the basis of coefficients of meshing point.Besides,mode analysis model of mutiple-arc gear was established by differential equations to provide theoretical basis for avoiding the resonance in the process of gear meshing transmission and then studying the form of fundamental vibration.Finally,under the circumstance of ADAMS software,factors such as number of arcs,speed,transmission error(certens-distance tolerance and axis parallelism deviation)and other errors were modeled to analyze the effect on the stability of mutiple-arc gear transmission.And the vibration was analyzed on the basis of meshing frequency and mode analysis model to understand the vibration of mutiple-arc gear and main the form of vibration.
