SEALING STRUCTURE FOR ROBOT JOINT AND ROBOT JOINT INCLUDING SUCH SEALING STRUCTURE

WIPO Patent Application WO/2022/051989

A1

A sealing structure for a robot joint (1000) and a robot joint (1000) are provided. The sealing structure comprises a first sealing member (300) adapted to be connected to a first part (100) of the robot joint (1000) and a second sealing member (400) adapted to be arranged between the first sealing member (300) and a second part (200) of the robot joint (1000) and in contact with the first sealing member (300). The first part (100) is rotatable with respect to the second part (200). The material of the first sealing member (300) is harder than the material of the second sealing member (400). A robot joint (1000) comprises the sealing structure. With such a sealing structure, the reducer (500) is closely sealed from the ambient environment. In this way, the leakage of the reducer (500) can be prevented for an extended period even in harsh conditions and thereby the service life of the robot joint (1000) can be prolonged.
