Designing Kinematic Schemes of Automatic Gearboxes with Angular Velocity Diagrams of Planetary Gear Links Having Three Degrees of Freedom 2006-01-1643

Though planetary gears (PGs) are widely applied in automatic gearboxes, there is no systematized method for selection of their kinematic schemes (KSs). Therefore, to develop a complex PG, designers use an existing KS or create a new KS without being assured that the selected KS is the most advanced one. For every specific case, a wide range of gears made on the basis of different KS can be suggested. Choosing between the schemes by comparison is impossible, mainly because one cannot find all KS satisfying the initial specification without a systemic approach. In case of a wrong selection of KS constructed as a result of random search, a designer cannot implement advantages of planetary gearboxes in his construction. Therefore, selecting the optimal KS is the crucial stage in designing a new PG.
