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: A stopper apparatus for robot rotary joint, for limiting the rotation angle of a turning shaft. The stopper apparatus includes: a rotary protrusion, fixed to the shaft and extended from an outer circumference surface of the shaft; a ring-like orbit, fixed to a mounting housing of the robot rotary joint, inserting the shaft therein; a first slider and a second slider, rotatably accommodated in the orbit and able to push each other to rotate; a stop protrusion, fixed to the housing of a robot rotary joint and extended in the direction of the center of the shaft; the rotary protrusion is able to directly push the second slider to rotate, while it is not able to directly push the first slider to rotate; the shaft, the rotary protrusion and the second slider cannot be obstructed by the stop protrusion when rotate, while the first slider is able to be obstructed by the stop protrusion when rotate, thereby the relative rotation between the shaft and the housing can be stopped. The present invention also provides a rotary joint and a robot. Compared with the existing prior arts, the proposed solution enables a rotation range larger than ±360 degrees.
