Abstract

This paper presents an alternative to the Traditional Gear Design (TGD) concept as well as to some modern approaches, including the Direct Dear Design (DGD) method, which separates gear geometry definition from tool selection. The proposed method called the Combined Blocking Contours (CBC) concept represents a system of some combination of various mathematical and graphic approaches and allows defining the shift coefficients as well as many other quality characteristics of involute gearing of a single-row planetary mechanism named usually as 2K-h type. The CBC concept provides the optimal choice for the geometrical parameters of gearings and can be effectively used at the initial stage of a gear design for both: when designing involute planetary reducer and animator, thus, achieving the best quality of a mechanism as a whole.
