GIICL drum gear coupling

GIICL drum gear couplings are widely used in drum gear couplings because the angular compensation of drum gear couplings is greater than that of straight gear couplings. Straight gear couplings are obsolete products. Those who choose should try not to choose.

Type I-The sealed end is a separate type, with a large tooth spacing, which can allow a large radial displacement, and can be connected with Y, J1, and Z1 shaft extensions.

Type Ⅱ-The sealing end is integral, with small tooth spacing, relatively small radial displacement, compact structure, small moment of inertia, and can be connected with Y and J1 shaft extensions.

GIICL drum gear coupling has the ability to compensate for axis deviations such as radial, axial and angular axis. It has the advantages of compact structure, small gyration radius, large carrying capacity, low transmission, low noise and long maintenance cycle. It is especially suitable for low speeds. Heavy-duty working conditions, such as metallurgy, mining, lifting and transportation industries, and also suitable for shaft transmission of various machinery such as petroleum, chemical industry, general machinery, etc. The drum gear coupling belongs to the rigid-flexible coupling. The type coupling 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 center of the spherical surface is on the gear axis. The tooth side clearance is larger than that of ordinary gears. The drum-shaped gear coupling can Allows larger angular displacement (compared to the straight tooth coupling), the contact condition of the tooth can be improved, the ability of transmitting torque is improved, and the service life is prolonged.The contact state along the tooth width when there is angular displacement.When the gear coupling is working, the two shafts produce relative angular 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 consumption. Therefore, the gear coupling must have a good and Work in a sealed state.Gear couplings have small radial dimensions and large load-bearing capacity. They are often used in shaft transmissions under low-speed and heavy-duty conditions. The dynamically balanced gear couplings can be used for high-speed transmissions, such as gas turbine shaft 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 those who choose them should try not to use them.

The characteristics of GIICL drum gear couplings (compared to straight gear couplings with the following characteristics): 1. Drum gear couplings have strong carrying capacity.Under the same outer diameter of the inner gear sleeve and the large outer diameter of the coupling, the carrying capacity of the drum gear coupling is 15-20% higher than that of the straight gear coupling on average, and the angular displacement compensation is larger.When the radial displacement is equal to zero, the allowable angular displacement of the spur gear coupling is 2o, and the allowable angular displacement of the drum gear coupling is 1o1', an increase of 30%.Under the same modulus, number of teeth, and tooth width, the allowable angular displacement of the drum-shaped gear is larger than that of the straight tooth. 50. The drum-shaped tooth surface of the drum-shaped gear coupling makes the contact condition of the inner and outer teeth avoid the angle Under the condition of displacement, the edge of the straight tooth is squeezed and the stress is concentrated. At the same time, the friction and wear of the tooth surface are reduced, the noise is reduced, and the maintenance cycle is long. 3. The tooth end of the outer gear sleeve of the drum-shaped gear coupling is in the shape of a horn, which makes the assembly and disassembly of the inner and outer gears easy. 4. The transmission of drum gear coupling reaches 5%.Based on the characteristics of warp, at present, drum-shaped gears have generally been substituted for straight-tooth couplings.
