本文讨论由双星或双联行星或三联行星构成的多元件行星齿轮传动,分析其运动学方程组和速度平面图及共复合机构,建立设计多元件行星齿轮变速箱的理论方法和步骤。 一个多元件行星排所能实现的档数,相当于3到5个普通三元件行星排所组成的行星传动的档数,其复合应用所能实现的档数更多。因而按要求的一定传动比值设计的力案和结构可以得到简化,带来在尺寸、重量,效率和成本等许多方面的优点。此外,在任何情况下不会出现传动内部的功率循环。 本文所提出的规律和理论方法是在三元件行星传动和换联式三自由度行星传动方案设计基础上的进一步发展,使行星变速箱方案设计理论扩展到一个新的领域,可以方便地创造出实现所需传动此的许多优良方案。
In this paper, we discuss the multi-element planetary gear transmission composed of double or double or triple planets, analyze the equations of kinematics, velocity plan and co-compound mechanism, and establish the theoretical method and steps for designing multi-element planetary gearboxes. The number of gears that a multi-element planetary row can achieve is equivalent to the number of planetary gears made up of 3 to 5 ordinary three-element planetary rows, and the number of gears that can be achieved by the composite application is more. As a result, designs and structures designed for a given transmission ratio can be simplified to many advantages in terms of size, weight, efficiency and cost. In addition, no power cycles inside the drive can occur under any circumstances. The law and theory proposed in this paper are further developed based on the design of three-element planetary transmission and three-degree-of-freedom planetary transmission scheme. The theory of planetary gearbox design is extended to a new field and can be easily created Achieve the desired transmission of many good programs.
