Reliability Optimization Design and Solid Modeling of Cylinder Gear Speed Reducer

Taking the randomness of the stress and strength into consideration,regarding the given reliabilities of the tooth contact and the root bending fatigue strength as constraints and applying the mechanical optimization design theory,a multi-objective reliability optimization model of single-grade helical gear speed reducer is built to determine the parameters of the gear mechanism.The solid model of the gear speed reducer is established by the SolidWorks software and its motion simulation is realized by the COSMOSMotion plug-in,which provides a practical and feasible approach to design the gear speed reducers by the computer-aided method.
