In order to solve the technical problems, the technical scheme of the application provides a crossed roller bearing with a special-shaped structure, which is characterized by comprising a bearing outer ring and a bearing inner ring, wherein rhombic raceways which are matched with each other and used for accommodating rollers are arranged on the inner side surface of the bearing outer ring and the outer side surface of the bearing inner ring, and adjacent rollers are arranged in the raceways in a crossed manner; the bearing outer ring is of a special-shaped structure, a plane is arranged on the outer side face of the bearing outer ring, a ball mounting hole communicated to the rhombic raceway is formed in the outer side face of the bearing outer ring, the ball mounting hole is formed in the plane, and a roller is mounted in the raceway through the ball mounting hole; and an outer ring wedge block for sealing the ball mounting hole is arranged in the ball mounting hole and is connected with the bearing outer ring.
Preferably, the number of the planes is four, and the planes are uniformly distributed along the circumference of the outer side surface of the bearing outer ring.
Preferably, a through unthreaded hole is formed in the end face of the bearing outer ring, and the position of the unthreaded hole on the end face avoids the range of the plane.
Preferably, the outer ring wedge block is detachably connected with the bearing outer ring.
This application advantage lies in, bearing inner race adopts and has planar heterotypic structure, can adapt to the bearing frame that has the heterotypic hole, utilizes the plane to set up dress ball hole at bearing inner race's lateral surface simultaneously, avoids destroying integratively at the terminal surface fluting of bearing inner race and/or bearing inner race, and the efficiency of just driling on the plane is far more than fluting on the terminal surface.
