    Gear coupling GIICL type

    description:Gear coupling GIICL type is composed of internal gear ring with the same number of teeth and flange half coupling with external teeth.The external teeth are divided into straight teeth and drum teeth. The so-called drum teeth means that the external teeth are made into a spherical surface, which is on the axis of the gear.
    Detailed introduction:

    Gear couplingGIICL type is composed of internal gear ring with the same number of teeth and flange half coupling with external teeth.The external teeth are divided into straight teeth and drum teeth. The so-called drum teeth means that the external teeth are made into a spherical surface. The spherical surface is on the gear axis. The tooth side clearance is larger than that of ordinary gears. Drum-shaped gear couplings allow Larger angular displacement (compared to spur gear couplings), the contact conditions of the teeth can be improved, the torque transmission capacity is improved, and the service life is prolonged.When the gear coupling is working, the two shafts produce relative displacement, and the tooth surfaces of the internal and external teeth periodically slide relative to each other in the axial direction, which will inevitably cause tooth surface wear and power loss. Therefore, the gear coupling needs to be well lubricated and sealed. Work in the state.

    Gear couplings have small radial dimensions, large carrying capacity, and are long used for shafting transmissions under low-speed and heavy-duty conditions. The dynamically balanced gear couplings can be used for high-speed transmissions, such as gas turbine shafting transmissions. .Because the angular compensation of drum gear couplings is greater than that of straight gear couplings, drum gear couplings are widely used. Straight gear couplings are obsolete products and should not be used as much as possible.

    The torsional vibration of the gear coupling is analyzed. The Fourier series solution is mainly used to analyze the torsional vibration of the gear coupling connecting shaft system with clearance, damping and excitation force as parameters; then A large number of tests have been carried out on the axial vibration of the gear coupling connecting shaft system, and the main reason for the axial vibration is qualitatively explained. It is pointed out that the axial vibration is mainly caused by the misalignment and the friction of the tooth surface. Larger axial movement will occur during axial restoring force or thrust bearing.
