The inner hole of the coupling matches the shaft center

The inner hole of the coupling is matched with the shaft center. The inner hole of the coupling is matched with the shaft center.

  For some special situations and special occasions, the design can be separated from the design manual or customary interference fit, and adjusted appropriately according to the field of use.

    1. Where spare parts are consumed quickly and need to be replaced frequently

 In some special industries, spare parts are consumed quickly in special occasions and need to be disassembled and replaced frequently. These shaft extensions can be matched with H7/N6 and H7/GB.

    2. Low-speed, heavy-duty, and no coupling centering occasions

    Although some places have low speed and heavy load, but the impact and vibration are small, the coupling is only used to transmit the torque and does not need to fix the center position. For example, CL type couplings can adopt clearance fit. It does not affect the use, but also brings convenience to the maintenance and repair of the equipment.

    3. In spite of the impact and vibration, it can be taken over by flexibility

   For some occasions where the torque is not large, the impact and vibration are more serious, but the flexible handle can also be used for clearance fit. At this time, the vibration and impact generated between the shaft extension and the coupling can be eliminated by the elastic device in the middle, and there is no need to make a big move if it needs to be disassembled.

   In short, all couplings that transfer torque by key, as long as it does not affect the use, can adopt transition or clearance fit, which will bring great convenience to the maintenance and installation of the equipment.

The selection of the inner hole of the coupling and the shaft center:

    In the process of maintenance or installation of mechanical equipment, it is often encountered that the coupling hole and the shaft center are too tight. It is often difficult or impossible to disassemble the coupling at all. For these problems, our method is to reduce the basic deviation of the shaft extension matched with various couplings in order to reduce the waste of manpower and material resources during the maintenance of mechanical equipment.
