GIICLZ-Drum Tooth Coupling

Because the angular compensation of drum gear coupling is larger than that of straight gear coupling, drum gear coupling is widely used at home and abroad. Straight tooth coupling belongs to the obsolete product, so the selector should not choose it as far as possible.

  When GII CLZ-drum gear couplings work, the relative angular displacement of two axes occurs, and the tooth surfaces of inner and outer teeth slide relative to each other periodically, which inevitably leads to tooth surface wear and power consumption. Therefore, the gear couplings need to work in a good and sealed state.

  Tooth couplings are small in radial dimension and large in load carrying capacity. They are often used in shafting transmission under low speed and heavy load conditions. Tooth couplings with high accuracy and dynamic balance can be used in high speed transmission, such as shafting transmission of gas turbine. Because the angular compensation of drum gear coupling is larger than that of straight gear coupling, drum gear coupling is widely used at home and abroad. Straight tooth coupling belongs to the eliminated product, so the selector should not choose it as far as possible.

  Type I-sealing end is separated type, with large spacing between teeth, which allows larger radial displacement and can be connected with Y, J1 and Z1 axes.

  Type II-sealing end is integral, with small spacing between teeth, small relative allowable radial displacement, compact structure and small moment of inertia. It can be connected with Y and J1 axes.

  Main features (compared with straight-tooth coupling, it has the following characteristics):

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

  2. Angular displacement compensation is large. When the radial displacement is equal to zero, the allowable angular displacement of straight-tooth coupling is 1o, while that of drum-tooth coupling is 1o30', increasing by 50%. Under the same modulus, number and width of teeth, the angular displacement of drum teeth is larger than that of straight teeth.

  3. The drum-shaped tooth surface improves the contact condition between inner and outer teeth, avoids the drawbacks of edge extrusion and stress concentration of straight teeth under angular displacement condition, improves the friction and wear condition of the tooth surface, reduces noise and prolongs 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, drum teeth have been widely used to replace straight coupling at home and abroad.
