Kinematics, Geometry, and Design Features of 2-DOF Gearing
Potentially, the total number of possible 2-DOF gearing is large. In order to consider all the possible 2-DOF gearing, one may wish to employ the classication of possible vector diagrams of gearing (Figure 1.17). Using this classication, it is possible to investigate what kind of additional motion, if any, could be added to each of the vector diagrams in order to come up with the concept of a corresponding 2-DOF gearing. This particular problem is out side the scope of this book. The goal is to illustrate the design of 2-DOF gearing that is already used in the industry, as well as those that are potentially useful in practice.
