  • Publication number: 20240360894
    Abstract: A stirring component includes a body arranged in an internal chamber at a side of a circular spline away from a flex spline of the harmonic transmission system. The body includes a coupling hole through which the body is coupled to and rotated with an input shaft of the harmonic transmission system, and at least one stirring recess arranged on a side of the body adjacent to the circular spline and has a varying depth in an axial direction to stir and push lubricant medium within the internal chamber towards the flex spline during rotation of the body. With the stirring component arranged within the internal chamber, the plate-shaped body can block the lubricant medium from moving further. Furthermore, the stirring component can stir and push the lubricant medium away from the body towards the flex spline.

  • Patent number: 12031630
    Abstract: A ring seal and a robot. The ring seal includes an outer circumferential wall and an annular portion. The outer circumferential wall extends in an axial direction of the ring seal. The annular portion extends from a side of the outer circumferential wall toward an interior of the outer circumferential wall in a radial direction of the ring seal. As viewed in a cross section taken along the radial direction, the annular portion and the outer circumferential wall form an L shape.

  • Patent number: 10913167
    Abstract: A sealing arrangement for application in a robot joint. The sealing arrangement includes: a circular sealing assembly arranged between a swing and a base of the robot joint in a longitudinal direction, the circular sealing assembly defining a tubular cavity in a circumferential direction and having a gas inlet and a gas outlet; and an air channel coupled to the gas inlet and operable to continuously conduct pressured air flow into the cavity to maintain an air pressure inside the cavity above an air pressure outside the cavity, and thereby a high-speed airflow out of the gas outlet.
