By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News – According to news reporting originating from Washington, D.C., by NewsRx journalists, a patent application by the inventors GUO, Ziming (Foshan, CN); ISAJI, Tsuyoshi (Foshan, CN); LIN, Wenjie (Foshan, CN); MINEGISHI, Kiyoji (Foshan, CN); WANG, Gang (Foshan, CN), filed on October 24, 2023, was made available online on February 15, 2024. No assignee for this patent application has been made. Reporters obtained the following quote from the background information supplied by the inventors: “An eccentrically swinging type gear device in which a planetary gear swings eccentrically while internally meshing with an internally toothed gear may include an eccentric body that is integrally formed with an input shaft. The planetary gear may be mounted in the eccentric body via an eccentric body bearing. External teeth with an arc tooth shape or the like are formed on a periphery of the planetary gear. “The internally toothed gear is formed by mounting multiple external pins (roller pins) constituting internal teeth one-by-one into an inner peripheral surface of a gear body (internally toothed gear body) used as a housing in a free rotation manner. In the planetary gear, multiple inner pin holes (inner roller holes) are formed at proper intervals in a circumferential direction, and inner pins and inner rollers are inserted into the inner pin holes. The inner pin is connected to a bracket at an end side in an axial direction thereof, and the bracket is supported on the housing via a cross roller bearing in a free rotation manner. The gear device may be used as a gear device which takes out, from the bracket, rotation of the planetary gear corresponding to a self-rotation component when the internally toothed gear is fixed.”
