CL-type gear coupling is a rigid coupling, the number of teeth by the same ring and the outer teeth of the flange half coupling and other components. When the gear coupling is in operation, the two axes produce relative angular displacement, and the tooth surface of the inner and outer teeth is axially relative to each other, and it needs to work in a well and sealed state. Drum-shaped gear coupling allows a larger angular displacement (relative to the straight coupling), can improve the contact conditions of the teeth, improve the ability to transmit torque, extend the service life. Angular contact state along the tooth width. It has the advantages of compact structure, low radial radius, large carrying capacity, high transmission efficiency, low noise and long maintenance period. It is especially suitable for low-speed heavy-duty conditions, such as Metallurgy, mining, lifting transport and other industries, but also for petroleum, chemical, general machinery and other machinery shaft drive.

    Dental coupling radial size is small, carrying capacity, commonly used in low-speed heavy-duty conditions of the shaft drive, high precision and dynamic balance of the gear coupling can be used for high-speed transmission, such as the steam turbine shaft transmission. As the drum-type gear coupling angle compensation is greater than the straight-type coupling, both at home and abroad are widely used drum-type gear coupling, straight-tooth coupling is out of the product, the user should try not to use The

    Drum-shaped gear coupling features (compared with the straight-type coupling has the following characteristics):

1, carrying capacity. In the same outer diameter and the maximum outside diameter of the coupling, the drum-type coupling capacity of the coupling capacity than the straight-tooth coupling increased by 15 to 20%

2, angular displacement compensation. When the radial displacement is equal to zero, the allowable angular displacement of the straight-tooth coupling is 1o, and the permissible angular displacement of the drum-type coupling is 1o30 ', which is increased by 50%. In the same modulus, the number of teeth, tooth width, the drum teeth than the straight tooth to allow large angular displacement,

3, drum-shaped tooth surface to the internal and external contact conditions improved, to avoid the angular displacement of the mandibular tooth edge edge squeeze, stress concentration defects, while improving the tooth surface friction, wear conditions, reduced Noise, long maintenance cycle.

4, the outer teeth of the tail end was the shape of the speaker, so that the internal and external tooth assembly is very convenient.

5, the transmission efficiency of up to 99.7%.

Based on the characteristics of the past, at home and abroad has been generally replaced by drum teeth tooth straight coupling.
