CPC classification number: B25J19/0079 , F16J15/406
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.
