    The main advantages of drum gear couplings are:

    1, Gear coupling has small radial size and large load capacity. It is often used for shafting transmission under low speed and heavy load conditions. The dynamically balanced gear coupling can be used for high-speed transmission, such as the shafting transmission of gas turbines. .Since the angular compensation of drum gear couplings is greater than that of straight gear couplings, Lingsi drum gear couplings are widely used.Drum-type gear couplings are rigid-flexible couplings.

    2, The external teeth of drum-shaped gear couplings are divided into two types of teeth, straight teeth and drum-shaped teeth. Drum-shaped gear couplings can allow larger angular displacement (compared to straight-tooth couplings), which can improve The contact condition of the teeth improves the torque transmission capacity and prolongs the service life.The contact state along the tooth width when there is angular displacement.

    3, Drum gear coupling has radial, axial and angular axis deviation compensation capabilities, has the advantages of compact structure, small gyration radius, large carrying capacity, transmission, low noise and long maintenance cycle.When the drum gear coupling is working, therefore, the gear coupling needs to work in a good and sealed state.

    4, After carburizing and quenching treatment of drum-shaped tooth meshing tooth surface, the bearing capacity is high; the main failure mode of drum-shaped tooth is wear. After using forced thin oil lubrication, the tooth surface wear is greatly reduced, and the amount of wear is the percentage of grease lubrication. Of10Around the left and right, the circulating thin oil can take away the rolling heat at the end of the roll and the heat generated by the friction of the gear teeth, preventing the reduction of the allowable contact stress on the surface of the gear tooth material; under normal circumstances, there will be no tooth breakage, which meets the working characteristics of continuous rolling mills. Requirements: The drum-shaped gear coupling can meet the requirements of rolling mill shifting rolling, and it is very convenient to expand and contract.
