This paper deals with gearing of a novel design. Insensitivity to the gear axes misalignment is the principle feature of gearing of the proposed design. The discussion begins with a brief historical overview on design of geometrically-accurate gearing. Then, fundamentals of gearing that is insensitive to the axes displacements are discussed. Elements of kinematics, an actual configuration of the gear axes of rotation, and so forth are covered in this discussion. Analytical expressions for tooth flanks of a gear and a mating pinion for gearing of the proposed design are derived. Features of interaction of tooth flanks of a gear and a mating pinion are briefly discussed. The paper ends with the analysis of potential applications of “ Spr pr gearing”, and conclusion.
