Abstract
The invention discloses a disassembling tool and disassembling method for a bevel gear component bearing. According to the disassembling tool, the separable combination principle, namely all components are linked with one another, is adopted for design. The disassembling tool comprises a falcula, a lower supporting plate, a reinforcing ring, pull rods, an upper supporting plate, a press block and a threaded rod. During disassembly, firstly, the reinforcing ring is lifted to a certain height and rotated in the axial direction until the reinforcing ring is suspended in annular grooves in the pull rods; secondly, the falcula is pulled outwards until the falcula can not be pulled outwards anymore; thirdly, the disassembling tool is pick up at the moment, the press block is supported and abutted against the small end face of the upper portion of a bevel gear shaft, and then the falcula is slid to the center until the falcula is attached to the lower supporting plate, inserted into a disassembling notch and attached to the bottom surface of the bearing; and finally the reinforcing ring is rotated in the opposite direction and dropped down at the same time, the falcula is sleeved with the reinforcing ring, the outer circle of the falcula is hooped, and the bearing is disassembled gradually by rotating the threaded rod at the moment. The disassembling tool is convenient to operate and fast and saves labor, and referential experiences are provided for similar problems.
