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.
