Dismounting device for internal rubber mixer rotor bearing

Abstract

The invention relates to a dismounting device for an internal rubber mixer rotor bearing. The dismounting device comprises a frame, a lifting screw, an oil cylinder, a hydraulic pump, a master jaw body, a master jaw, jaws and hooks, wherein the frame is provided with a sliding groove, the lifting screw is mounted on the frame, the oil cylinder is fixedly connected with the bottom of the lifting screw through a sliding plate, the hydraulic pump is used for driving the oil cylinder to actuate, the master jaw body sleeves the front end of the oil cylinder, the three master jaws are uniformly distributed on the outer surface of the master jaw body and are provided with hollow groove bodies, the three jaws are in sliding connection with the hollow groove bodies of the three master jaws respectively, and the three hooks are respectively mounted at the front end of the three jaws. The dismounting device has the beneficial effects that the bearing dismounting efficiency during replacing and assembling an internal rubber mixer rotor bearing can be improved; the height and the diameter can be regulated, so that the dismounting device can be used by internal rubber mixers of different types; a three-jaw structure is uniformly distributed at the peripheral direction of the bearing during dismounting, so that the stress is uniform, and the bearing cannot be damaged.

Description

technical field [0001] The invention relates to a dismantling device for a rotor bearing of a closed rubber mixing machine, which belongs to the rubber tire manufacturing industry. Background technique [0002] At present, the rotor bearing of the known closed rubber mixing machine is installed in the side bracket, wherein one end of the inner hole of the bearing is a closed structure, and the bearing cannot be pushed out from the other end during disassembly. [0003] The disassembly method in the prior art is mainly to remove the bearing from the rotor by manually tapping the surface with a jack wire or a copper hammer. Since the rotor bearing has a large width, and the outer circle of the bearing needs to be knocked during disassembly, it is not only time-consuming and labor-intensive, but also easy to disassemble. damage to the bearing surface. [0004] Therefore, it is necessary to propose an effective technical solution to solve the above problems. Contents of the i...
