ABSTRACT
The kinematics and geometry of noninvolute gearing are of scientific interest and practical importance for gear engineers, as they are broadly used in industry, especially in cases when slow rotations are transmitted. In spur noninvolute gear pairs, only one pair of teeth is engaged in mesh at every instant of time. This chapter talks about schematic of an external pin gearing. External and internal pin gearing of cycloidal gearing can be designed for the purpose of transmitting a rotation between two parallel shafts. The generation of the gear tooth profile can be executed in two steps. First, to generate the gear tooth addendum, consider rolling with no sliding of an auxiliary axode over the gear pitch circle. Second, to generate the gear tooth dedendum, consider rolling with no sliding of an auxiliary axode of a radius over the gear pitch circle of a radius.
