Rubber bearing sealing ring with framework for robot bearing

The invention discloses a rubber bearing sealing ring with a framework for a robot bearing, relates to the technical field of bearing sealing, and aims to solve the problems of large bearing temperature rise and large friction torque of the existing robot bearing sealing mode while ensuring the sealing effect of the robot bearing. Comprising a sealing ring body, a framework is arranged on the sealing ring body, sealing lips are arranged on the inner side wall of the sealing ring body and comprise a first lip, a second lip and a third lip which are sequentially arranged in the axial direction of the sealing ring body and are independent of one another, and the first lip is of a thin-wall structure and makes contact with the outer circle face of a bearing inner ring; the second lip and the third lip are both in clearance fit with the outer circle face of the step of the bearing inner ring, a groove is formed between the second lip and the third lip, and the second lip is in clearance fit with the step face of t
