The invention discloses an impeller hub dismounting device. The impeller hub dismounting device comprises a dismounting device composed of a double head bolt, a lead screw and a flange plate, and further comprises a clamping fixture connected with the dismounting device. The clamping fixture comprises a hollow shaft. The lead screw penetrates through the hallow shaft. A fourth circular truncated cone of the hallow shaft is arranged on the hallow shaft. Symmetrical radial through holes are formed in an extending end on one side of the hallow shaft. A handle is fixedly connected with the hallow shaft through the radial through holes. Lock nuts, nuts and gaskets, thrust ball bearings, check rings and deep groove ball bearings are respectively arranged on a first circular truncated cone and a second circular truncated cone of the hallow shaft on an external screw thread step end of the other side of the hallow shaft. A central through hole inside a jacket is matched with the hallow shaft. Jacket second circular truncated cones on two sides of the jacket are matched with the thrust ball bearings. Jacket third circular truncated cones are matched with the deep groove ball bearings. One end of the jacket is parallel and level with the fourth circular truncated cones of the hallow shaft. A base plate is sleeved on the hallow shaft. An inner circle on the other end of the jacket and an inner circle of the base plate are fixedly connected after centration. The impeller hub dismounting device is compact in structure, convenient to carry, easy to operate, and greatly improves work efficiency.
Description
technical field [0001] The invention belongs to the technical field of equipment maintenance of rotating machines such as fans, and relates to a dismantling device, in particular to a portable impeller hub dismantling device which integrates disassembly and installation of the impeller hub. Background technique [0002] At present, the existing devices for removing and installing the hub of the impeller are independent. [0003] There are two commonly used ways to disassemble the impeller hub. One is to use the mechanical principle of screw transmission, and the disassembly device is composed of a flange, a lead screw and a stud bolt. The disassembly steps are as follows: [0004] Insert a convex round table into the internal thread blind hole reserved at the end of the shaft extension of the motor shaft; [0005] Connect 2 to 4 uniformly distributed slotted holes on the flange with 2 to 4 uniformly distributed internal thread blind holes reserved on the outer end surfa...
