Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the embodiments of the present invention and the accompanying drawings, and obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-4, a replacer for replacing a vertical type seated bearing comprises a fixed base 1, a lead screw 2 and a top sleeve 3, wherein a through hole matched with a transmission shaft is formed in the middle of the fixed base 1, the two symmetrical lead screws 2 are fixedly mounted on the fixed base 1, the top sleeve 3 is mounted on the lead screws 2, the top sleeve 3 is in threaded connection with the two lead screws 2, a through hole for the transmission shaft to pass through is formed in the middle of the top sleeve 3, an annular boss bayonet 4 coaxial with the through hole in the middle of the top sleeve is arranged on a working surface of the outer end of the top sleeve 3, according to the design of a vertical type seated bearing inner ring, the annular boss bayonet 4 is matched with the bearing inner ring during working, when the top sleeve 3 moves upwards, the annular boss bayonet 4 props against the bearing inner ring, the bearing inner ring is tightly attached to the bearing. One section of the threaded end of the screw rod 2 is subjected to turning, diameter reducing and axial drilling and tapping treatment, the screw rod 2 is axially positioned and fixed on the fixed base 1 through locking of two nuts, and the other end of the screw rod 2 is an outer hexagonal end. The fixed base 1 and the top sleeve 3 are both of hoop type structures, are respectively formed by two half hoops in a closing mode, are locked through bolts, are convenient to embrace the fixed base 1 and the top sleeve 3 on a transmission shaft, and are convenient to disassemble and assemble. Two ends of a screw rod 2 are correspondingly provided with a half hoop of a fixed base 1 and a half hoop of a top sleeve 3, the three are connected to form a half structure of the replacer, and the two half structures of the replacer are combined to form the integral replacer through bolt locking. When the vertical type bearing with the seat is disassembled and assembled, the fixing base 1 is fixedly locked on the transmission shaft, the jacking sleeve 3 is tightly attached to the inner ring of the vertical type bearing with the seat and then is clamped on the transmission shaft, finally the screw rods 2 are respectively in threaded connection with the jacking sleeve 3 and penetrate through the fixing base 1 to be in clearance fit, the screw rods 2 are axially positioned on the fixing base 1 through nuts, and the screw rods 2 can rotate on the fixing base 1.
