    CLZ type gear coupling (JB/ZQ 4218-86)

    　　　The high-torque drum-shaped gear coupling has good impact bearing performance, but the tooth surface contact stress and tooth root bending fatigue strength require high requirements. If we adopt special structures, special materials, and special processes, the coupling can meet the requirements of large Requirements for diameter pipe rolling mills.With the development of China’s economy, the demand for large-diameter pipe rolling mills has increased, and the requirements for couplings used in the main drive have become higher and higher. Couplings that meet this requirement include cross universal couplings and large torque drums. Gear couplings, of which the torque of the cross universal coupling can be reached, but the impact bearing performance is poor and the life is short, which is a big disadvantage; the current standard couplings used in domestic rolling mills cannot meet the requirements. Only 1/2 to 1/3 of the required transfer torque can be met by professional foreign coupling manufacturers. However, due to its special technology and the difficulty of manufacturing, it is extremely expensive.A pipe rolling mill requires about 10 sets, and the cost of outsourcing spare parts is very high.The various drum gear couplings developed by Tianshuo Coupling Factory according to customer needs have been able to meet the needs of various domestic manufacturers.
    　　When the gear coupling is working, the two shafts produce relative angular displacement, and the tooth surfaces of the inner and outer 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 be in good condition. 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.Because the angular compensation of the drum gear coupling is greater than that of the straight gear coupling.

    Drum gear couplingIt belongs to a rigid-flexible 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, etc.
    Drum gear couplingWhen 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 needs to work in a good and 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 straight gear couplings, drum gear couplings are widely used at home and abroad. Straight gear couplings are obsolete products. Those who choose should try not to use them. .
    Features of drum gear couplings (compared to straight gear couplings with the following characteristics)     :

    　　1. Strong carrying capacity.Under the same outer diameter of the inner gear sleeve and the maximum outer diameter of the coupling, the carrying capacity of the drum gear coupling is on average 15-20% higher than that of the straight gear coupling.

    　　2. Large 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 gear 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 spur tooth end edge extrusion and stress concentration 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 characteristics of the warp, at present, drum-shaped teeth have generally been substituted for straight-tooth couplings at home and abroad.
