| Abstract: | Design diagrams of wave gears with external deformation wave generators based on a parallel crank mechanism are considered. Wave gears can be used to develop new drives with a high-quality rating in terms of efficiency, kinematic accuracy, torsional stiffness, and interesting layout solutions. In order to obtain the best possible ratings of these gears, it is necessary to determine if there are redundant constraints in the design and to reduce (or eliminate) them. To do this, one of the modern structural analysis methods, the graph method, is used. It makes it possible to find circuits with redundant constraints and reasonably eliminate them. The simplicity and illustrativeness of the method are shown. |
