Abstract

The invention provides a disassembling device. The disassembling device comprises an outer positioning sleeve, at least two pulling members, an inner positioning part, a connecting piece, a supporting part and a threaded pull rod, wherein each pulling member is provided with a rod body and a hook body part which is positioned at a first end of the rod body; the outer surface of the rod body is matched with the inner surface of the outer positioning sleeve; a second end close to the rod body is provided with a first connection part; the outer surface of the inner positioning part is matched with the inner surface of the rod body; the side wall of the inner positioning part is provided with a second connection part; the pulling members are connected with the inner positioning part by the connecting piece through the first connection part and the second connection part; the supporting part is provided with a central through hole; and one end of the threaded pull rod passes through the central through hole to be connected with the inner positioning part, and the other end of the threaded pull rod is in threaded connection with a nut. The disassembling device is easy to operate, prevents parts from being scratched due to deviation during disassembling, and obviously improves disassembling operation efficiency.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a dismounting device. Background technique [0002] According to the maintenance and inspection requirements of the parts, it is necessary to regularly disassemble and inspect the parts installed in the deep hole, especially the parts in the main reducer. Conventional disassembly methods are: percussion method or temperature difference method, or both. The percussion method is mainly used in the occasions where the tightness between the deep hole parts and the installation inner hole is not large, and there is a large support plane, and the length-to-diameter ratio of the parts should not be too large. The percussion method is prone to improper operation and damage to the parts; temperature difference The method is mainly used in the case where the thermal expansion coefficient of the parts in the deep hole is different from that of the material in the installation hole. The assembly tigh...
