摘要
根据News Rx记者来自华盛顿特区的新闻报道，由发明家Livingston，Daniel(加利福尼亚州海沃德)；Ozog，Stefan(加利福尼亚州温尼伯)；Thable，Gagan Deep(加利福尼亚州卡尔加里)于2023年12月6日提交的专利申请于2024年6月6日在网上公布。本专利申请未转让给公司或机构。新闻编辑从发明人提供的背景信息中获得了以下引文：“传统的螺杆和螺母机构C提供了一种运动传动装置，该运动传动装置可以用于沿轴线机械地平移载荷(例如机器人)。当螺母径向分割成若干段时，通过仅在螺纹圆周的一部分接触并施加力到螺母，每个部分可以类似于常规蜗轮作用在螺纹杆(也称为“螺纹轴”和“螺钉”)上。与齿条配合以形成常规蜗杆传动C的蜗轮，用于沿V形轴向上或向下移动与蜗轮连接的机器人，这种常规蜗轮可以产生滑动摩擦阻力(例如，在蜗轮的操作过程中，蜗轮和齿轮或框架之间的摩擦。在传统的蜗轮传动中，滑动摩擦力与由WO RM齿轮传递到齿条的力矩成比例。此外，使用蜗轮相对于FR(例如，包括在自动存储和检索系统(AS/RS)中的机器人)提升有效载荷(例如，包括在自动存储和检索系统(AS/RS)中的机器人)。齿条)可以从载荷的W 8产生额外的固定摩擦阻力。该摩擦阻力可以造成很大的功率损失，并为蜗杆传动部件提供额外的磨损。通过能量守恒，它的功率主要转化为热量，其会导致材料性能下降，并危及与包括蜗杆传动部件的装置和/或机器S相关的人身安全。
Abstract
By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News-A patent application by the inventors Livingston, Daniel (Hayward, CA, US); Ozog, Stefan (Winnipeg, CA); Thable, Gagan deep (Calgary, CA), filed on December 6, 2023, was made available online on June 6, 2024, according to news reporting originating from Washington, D.C., by News Rx correspondents. This patent application has not been assigned to a company or institution. The following quote was obtained by the news editors from the background informa tion supplied by the inventors: "A conventional threaded rod and nut mechanism c an provide a motion transmission that can be used to mechanically translate a pa yload (e.g., a robot) along an axis. When the nut is split radially into a numbe r of sections, each section could act upon the threaded rod (also referred to as a "threaded shaft" and "screw") similar to a conventional worm gear by contacti ng and applying force to the nut at only a portion of the thread's circumference . As an example, a worm gear mated to a rack to form a conventional worm drive c an be used to move a robot coupled to the worm gear upward or downward along a v ertical axis in a controlled manner. Such a conventional worm gear can produce a sliding frictional drag force (e.g., friction between a worm gear and a toothed wheel or frame) during operation of the worm gear. In a conventional worm drive , the sliding frictional force is proportional to a torque transmitted by the wo rm gear to the rack. Further, using a worm gear to lift a payload (e.g., a robot included in an automated storage and retrieval system (AS/RS)) relative to a fr ame (e.g., rack) can generate an additional fixed frictional drag force from a w eight of the payload. This frictional drag force can contribute large power loss es and provide added wear to worm drive components. By conservation of energy, t his power is transformed primarily into heat, which can contribute to material p roperty degradation and risk human safety associated with devices and/or machine s that incorporate the worm drive components.
