The specific disassembly steps of the plum coupling and the factors to consider when choosing

     Before disassembling the plum-blossom coupling, make some marks on the positions where the various parts of the coupling cooperate with each other for reference when reassembling. Couplings used for high-speed machines, the connecting bolts are weighed and clearly marked, which cannot be mistaken.

    Cleaning, cleaning and quality evaluation of all parts of the plum coupling is an extremely important work after the coupling is disassembled. The evaluation of parts means that after each part is in operation, the existing conditions of its size, shape and material properties are compared with the quality standards determined by the design of the parts to determine which parts can continue to be used and which parts should be used. Used after repair, which are new parts that should be scrapped.

    During the torx coupling removal process, the difficult job is to remove the hub from the shaft. For keyed hubs, generally use a three-legged puller or a four-legged puller for disassembly. The selected puller should match the external dimensions of the wheel hub, and the right-angle hooks of each foot of the puller should be properly combined with the rear side of the wheel hub, so that no slippage occurs when force is applied. This method is only used for the disassembly of the hub with a relatively small interference. For the hub with a relatively large interference, the heating method is often used, or it is disassembled with a hydraulic jack at the same time.
