Abstract

The subject of this paper is a two-carrier planetary gear train (PGT) which was developed for a specific purpose. This PGT may be used for applications in which a negative transmission ratio in the range -3…-143 is required. In this case, the mechanical and dimensional properties of the PGT have been analyzed for nominal negative transmission ratios of -30 and -40. All possible combinations of simple component PGT ideal torque ratios providing those transmission ratios were obtained. Only the combinations providing the minimum radial dimensions of the PGT assembly were selected. Subsequent analysis has shown that the PGT radial dimensions will be minimized when the ratio of the reference diameters of the planetary unit ring gears is close to unity, meaning that the PGT casing will be cylindrical rather than stepped. This paper also provides an overview of the DVOBRZ software package used to synthesize the different gearbox layouts for the required transmission ratio, combined with a basic introduction to single speed two-carrier PGTs for better understanding. The DVOBRZ software was used to select all the acceptable gearboxes were selected from the set of generated PGTs according to the criteria of minimum dimensions and acceptable efficiency range. This set of PGTs was checked for kinematic feasibility and construction concepts were created for feasible layouts.

基于运动等效双载行星轮系尺寸和效率的比较

本文的主题是为特定目的而开发的双载行星轮系(PGT)。该PGT可用于需要负传动比在-3…-143范围内的应用。在这种情况下，PGT的机械和尺寸特性已经分析了名义负传动比-30和-40。在提供这些传动比的情况下，得到了所有可能的简单组件PGT理想转矩比组合。只选择提供最小径向尺寸的PGT组件组合。随后的分析表明，当行星单元环齿轮的参考直径比接近于1时，PGT的径向尺寸将最小，这意味着PGT的壳体将是圆柱形的，而不是阶梯形的。本文还概述了用于合成所需传动比的不同变速箱布局的DVOBRZ软件包，并结合对单速双载波pgt的基本介绍，以便更好地理解。采用DVOBRZ软件根据最小尺寸和可接受效率范围的标准，从生成的一组pgt中选择所有可接受的变速箱。这组pgt被检查为运动学可行性和施工概念创建为可行的布局。

期刊介绍： Engineering Review is an international journal designed to foster the exchange of ideas and transfer of knowledge between scientists and engineers involved in various engineering sciences that deal with investigations related to design, materials, technology, maintenance and manufacturing processes. It is not limited to the specific details of science and engineering but is instead devoted to a very wide range of subfields in the engineering sciences. It provides an appropriate resort for publishing the papers covering prior applications – based on the research topics comprising the entire engineering spectrum. Topics of particular interest thus include: mechanical engineering, naval architecture and marine engineering, fundamental engineering sciences, electrical engineering, computer sciences and civil engineering. Manuscripts addressing other issues may also be considered if they relate to engineering oriented subjects. The contributions, which may be analytical, numerical or experimental, should be of significance to the progress of mentioned topics. Papers that are merely illustrations of established principles or procedures generally will not be accepted. Occasionally, the magazine is ready to publish high-quality-selected papers from the conference after being renovated, expanded and written in accordance with the rules of the magazine. The high standard of excellence for any of published papers will be ensured by peer-review procedure. The journal takes into consideration only original scientific papers.
