    Product description of GⅡCL drum gear coupling:

    The drum gear coupling is a rigid coupling. The gear coupling is composed of an internal gear ring with the same number of teeth and a 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 a larger angular displacement (compared to the straight tooth coupling), which can improve the contact conditions of the teeth, increase the torque transmission capacity, and prolong the service life.The contact state along the tooth width when there is angular displacement.It has the ability to compensate for axis deviation in radial, axial and angular directions. It has the advantages of compact structure, small turning radius, large carrying capacity, high transmission efficiency, low noise and long maintenance cycle. It is especially suitable for low-speed and heavy-duty conditions, such as Metallurgy, mining, lifting and transportation industries, and also suitable for shafting transmission of various machinery such as petroleum, chemical industry, general machinery and so on.

    This structure is used for the direct connection of two horizontal concentric shafts. It is composed of two outer gear bushings and an inner gear ring. The lubricating oil used requires high viscosity and can flow, and is commonly used in vehicle oil.For couplings that work in the open air, lubricating oil with a lower viscosity should be used when the weather is cold.For general connection, all cylindrical shaft holes.

    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 shafting transmissions under low-speed and heavy-duty conditions. High-precision and dynamically balanced gear couplings can be used for high-speed transmissions, such as gas turbine shafting. transmission.Since the angular compensation of drum gear couplings is greater than that of spur gear couplings, drum gear couplings are widely used. Straight gear couplings are obsolete products, and those who choose should try not to choose them.

   Type I-The sealed end is a separate type, with a large tooth spacing, allowing a large radial displacement, and can be connected with Y, JXNUMX, and ZXNUMX 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 JXNUMX shaft extensions.

   Drum gear couplingMain features (compared with straight gear couplings, it has the following features):

    1. Strong carrying capacity.Under the same outer diameter of the inner gear sleeve and the 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.

    2. Large amount of angular displacement compensation.When the radial displacement is equal to zero, the allowable angular displacement of the spur gear coupling is 1o, and the allowable angular displacement of the drum gear coupling is 1o30', an increase of 50%.Under the same modulus, number of teeth, and tooth width, the allowable angular displacement of the drum tooth is larger than that of the straight tooth.

    3. The drum-shaped tooth surface improves the contact conditions of the inner and outer teeth, avoids the disadvantages of squeeze and stress concentration at the edge of the straight tooth under the condition of angular displacement, and at the same time improves the friction and wear of the tooth surface, and reduces Noise, long maintenance period.

    4. The tooth end of the outer gear sleeve is in the shape of a horn, which makes the assembly and disassembly of the inner and outer teeth very convenient.

    5. The transmission efficiency is as high as 99.7%.

    Based on the above characteristics, at present, drum-shaped teeth have generally been substituted for straight-tooth couplings.

    The advantages of drum-type gear couplings:
    Drum gear couplings are adaptive and self-tuning technologies that can compensate for load changes, especially distributed high-end drum gear couplings with communication, networking functions and integrated PLC; on the other hand, they are simple or industry-specific Drum-shaped gear couplings and mechatronics, miniaturized drum-shaped gear couplings.Drum-shaped gear couplings can allow greater angular displacement (compared to straight-tooth couplings), which can improve tooth contact conditions, increase torque transmission capacity, and extend service life.The contact state along the tooth width when there is angular displacement.

    The drum gear coupling has the ability to compensate for axis deviations in the radial, axial and angular directions, and has the advantages of compact structure, small gyration radius, large carrying capacity, high transmission efficiency, 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.Drum-shaped gear coupling has the advantages of small size, large transmission torque, strong ability to absorb coupling errors, and excellent durability. It is the most common component for connecting two drive shafts in medium and heavy machinery.
