On the Issue of Technological Support for the Serial Production of Cycloid Pinions

Technological support for the serial production involves a rational normalization of the product accuracy and the development of a competitive technological process. However, the accuracy standards for cycloidal gears have not yet been developed, and literature does not contain information on their serial production. The authors propose a possible algorithm for normalizing the accuracy of surfaces of a cycloidal profile and a technological process for the serial production of cycloid pinions. The algorithm for normalizing the accuracy is developed on the basis of the theory of contact deformations, and it is used in the system of automated design of cycloidal gears as a mean of technological control of design solutions. In order to reduce the cost of cycloidal gears, the technological process of serial production is formed from multi-site and multi-position operations. Electro-erosion processing is used as a method of shaping, ensuring the accuracy and quality of working surfaces. A stack of gears is cut out on a wire-cutting machine in one run from a stack of blanks after finish heat treatment and flat grinding of the butts. The efficiency sufficient for the serial production is achieved.
