In order to solve the technical problem, the utility model provides a centering bearing seat of nanometer sand mill, which comprises a body, wherein a bearing is arranged in the body, end covers are arranged at two axial sides of the bearing, the end covers are fixedly connected with the body, three pressing blocks are uniformly arranged on the inner wall of the body corresponding to the bearing, the pressing blocks are connected with a pressing screw, the pressing screw is in threaded connection with the body, one end of the pressing screw is arranged outside the body, and the three pressing blocks are matched with each other to press and fix the bearing;
the end cover on one side of the mechanical seal is provided with a positioning groove, a positioning pipe is arranged between the positioning groove and the mechanical seal, one end of the positioning pipe is provided with a positioning convex part, the positioning convex part and the positioning groove are matched for radial positioning, and the other end of the positioning pipe is fixedly connected with the mechanical seal.
Further, the bottom of the body is provided with a mounting seat.
Further, a mounting ring is arranged on the periphery of the body.
Furthermore, the surface of the pressing block on one side of the bearing is arc-shaped.
Further, the pressing block is formed by cutting the inner wall of the body.
Furthermore, an inner caulking groove is formed in the inner wall of the body corresponding to the pressing block, a limiting convex part is arranged on the notch of the inner caulking groove, and a limiting wing matched with the limiting convex part for limiting is arranged on the pressing block.
Furthermore, the pressing block is provided with anti-skid lines.
The utility model has the advantages that:
after the positioning tube is adopted, the mechanical seal and the bearing seat can be effectively connected and positioned with the body of the bearing seat, the mechanical seal and the bearing seat achieve the preliminary traction effect, and the positioning tube has the function of correcting the position.
Then, the bearings are fixed in the bearing seats by the three pressing blocks so as to realize the position self-adaption of the bearings in the bearing seats to the rotating shaft, thereby ensuring that the three axes are on the same straight line and ensuring the service life.
