Abstract: Embodiments of the present disclosure provide a sealing structure for a robot joint. The sealing structure comprise a first sealing member adapted to be connected to a first part of the robot joint and a second sealing member adapted to be arranged between the first sealing member and a second part of the robot joint and in contact with the first sealing member. The first part is rotatable with respect to the second part. A material of the first sealing member is harder than the material of the second sealing member. With such a sealing structure, the reducer is closely sealed from the ambient environment. In this way, the leakage of the reducer can be prevented for an extended period even in harsh conditions and thereby the service life of the robot joint can be prolonged.

Abstract: According to implementations of the subject matter described herein, there is provided a robot. The robot includes a motor mounted on a frame; a driving member having a shaft portion mounted to the motor and an output portion configured to engage a downstream driving member; a seal ring coupled to the frame and having an inner annular portion; and a collar secured to the shaft portion and having an outside peripheral surface in contact with the inner annular portion of the seal ring. A robot having a more reliable seal for protecting the motor can be achieved.

Abstract: A locking system and a manufacturing method thereof, a bearing assembly, and a robot having the same. The locking system incudes a first nut arranged on a shaft and adapted to contact with an upper side of an inner ring of the bearing. The locking system can also include a second nut arranged on the shaft and separated from the first nut at a predetermined distance. The locking system can include a locking screw adapted to be screwed through a first through hole of the second nut and a second through hole of the first nut while the first through hole and the second through hole are aligned with each other.

Abstract: A sealing assembly which has a housing adapted to be arranged on and cover an end of a first component of a robot. The sealing assembly includes a circumferential coupling section; a flange adapted to be arranged on and cover an end of a second component of the robot that is coaxially rotatable relative to the first component; and an elastic sealing ring. The elastic sealing ring includes a coupling portion coupled to the circumferential coupling section; and a sealing portion arranged between the housing and the flange with an interference fit.
