The analysis and synthesis of Ruppert-type gear trains

Abstract This paper describes the synthesis of two-axis gear trains of the Ruppert type. An analysis of these trains provides the data necessary for their design and bounds on the design variables. The parameters describing trains of both possible kinds, i.e. those with input and output shafts on the same axis or on different axes, are shown to be related. The techniques are illustrated by their application to a specific example.
