阅读说明：本技术 轨道立方体 (Track cube ) 是由 拉杜·阿佩特罗阿亚 于 2017-09-14 设计创作，主要内容包括：一种机械系统,包括两个相同的立方体刚性框架,该立方体刚性框架通过旋转连杆组件连接,该旋转连杆组件通过两个相同的行星齿轮机构同时操作,该行星齿轮机构分别容纳在每个立方体框架的体积内。整个机械组件具有作为运动学结构的手性双反射对称。这种运动学设计产生立方体相对于彼此的平移轨道运动,同时保持姿态并且还遵守直线轨迹。所述轨迹是立方体中的一个围绕另一个的360度性能所需的五个必要平移的总和。该系统实现了在两个面(每个立方体一个面)与平移平面之间或者两个边缘(每个立方体一个边缘)与相同直线之间的重合状态。包含于每个立方体框架内的每个机械组件只使用一个旋转输入作为驱动源。每个单独的机械组件由行星齿轮装置、由行星齿轮驱动的旋转连杆机构和周期性闭合形状的凸轮构成,该凸轮刚性地附接到行星架。所述凸轮通过齿条接合确定恒星齿轮的行为,该接合遵循特定函数的振荡。(A mechanical system comprising two identical cubic rigid frames connected by a rotating link assembly which is operated simultaneously by two identical planetary gear mechanisms housed respectively within the volume of each cubic frame. The entire mechanical assembly has chiral double reflection symmetry as a kinematic structure. This kinematic design produces translational orbital motion of the cubes relative to each other while maintaining pose and also following a straight line trajectory. The trajectory is the sum of the five necessary translations required for 360 degree performance of one of the cubes around the other. The system achieves a state of coincidence between two faces (one face for each cube) and the translation plane or between two edges (one edge for each cube) and the same straight line. Each mechanical assembly contained within each cube frame uses only one rotational input as a drive source. Each individual mechanical assembly consists of a planetary gear arrangement, a rotary linkage driven by the planetary gears and a periodically closed shaped cam rigidly attached to the planet carrier. The cam determines the behaviour of the sun gear by means of rack engagement, which follows oscillations of a particular function.)
