Optimization of Production Technology for Basic Elements of Planetary-Wave Gears with Intermediate Rollers

Abstract

The paper highlights the technology optimization of basic elements small-series production of planetary-wave gears with intermediate rollers: wave generator; intermediate rollers; a separator and a side wheel. The relevance of the paper is justified by continuously growing requirements to minimize the production costs concerning the improvement of metalworking equipment and technologies. Optimization of gear production technology is targeted on production cost reduction as well as improving its competitiveness on the basis of planetary-wave gears with intermediate rollers. Basic gear elements production technology optimization is considered together with the following factors: large-scale production; production costs; design features of products; form and elements surface position accuracy requirements; properties of materials. To optimize the production technology, the equidistant of wave generator is suggested to be obtained by turning operation with the application of special technological facilities. The intermediate roller is presented with the basic requirements and in the economic aspect it is suggested to be purchased as a mass product of the bearing industry. For the separator, the electroerosive and milling operations for obtaining windows are considered and recommendations on appropriate processing technology are given, depending on the purpose of the product. The basic requirements to the side wheel production are given as well as materials, which allow reducing the number of technological operations and transitions during profile processing, are recommended. Following the proposed recommendations can significantly reduce production costs, improve the competitiveness of products on the basis of planetary-wave gear train with intermediate rollers.
