        Features of drum type gear coupling

        Release time:2019-02-21
        Compared with CL type straight gear coupling, drum type gear coupling has the advantages of compact structure..

        Compared with CL type straight gear coupling, drum type gear coupling has the advantages of compact structure, small turning radius, large bearing capacity, high transmission efficiency, low noise and long maintenance cycle.

        Features of drum type coupling (compared with straight type coupling, it has the following features)

        1. Strong carrying capacity. Under the same outer diameter of inner sleeve and extra large outer diameter of coupling, the carrying capacity of drum type coupling is 15 ~ 20% higher than that of straight type coupling on average.

        2. Large angular displacement compensation. When the radial displacement is equal to zero, the allowable angular displacement of the straight-tooth coupling is 1o , while the allowable angular displacement of the drum gear coupling is 1o 30 ", increase by 50%, under the same modulus, the number of teeth, the width of the teeth, drum teeth than the allowable angular displacement of straight teeth;

        3. The drum tooth surface improves the contact conditions of the inner and outer teeth, avoids the disadvantages of edge extrusion and stress concentration at the end of the straight tooth under the condition of angular displacement, improves the friction and wear condition of the tooth surface, reduces the noise, and leads to long maintenance cycle;

        4, the tooth end of the outer tooth sleeve is shaped like a horn, which makes it very convenient to assemble and disassemble the inner and outer teeth.

        5. Transmission efficiency is up to 99.7%. Based on the above characteristics, drum gear has been widely used to replace the straight gear coupling at home and abroad. The types and specifications of drum type coupling produced by UMA are complete and accord with the corresponding standards. The drum type gear coupling, its rigidity is big, has the flexibility, inelastic, therefore is not suitable for the request to reduce the vibration, the buffer and the two axis in the request strictly mechanical.

        Can improve the contact conditions of teeth

        The outer teeth of the drum type coupling are divided into straight teeth and drum teeth. The drum type coupling can allow a large angular displacement (relative to the straight tooth coupling), which can improve the contact conditions of the teeth, improve the ability to transfer torque, and extend the service life. The contact state along the tooth width when angular displacement is present.

        The drum gear coupling has the advantages of compact structure, small turning radius, large bearing capacity, high transmission efficiency, low noise and long maintenance cycle etc. The drum type gear type coupling is in the work, therefore, the gear type coupling must have the good and under the seal condition work.

        Gear coupling radial size is small, bearing capacity is large, often used in low speed and heavy load conditions of the shaft drive, high precision and dynamic balance of the gear coupling can be used for high speed drive, such as gas turbine shaft drive. Because the angular compensation of the drum type coupling is larger than that of the straight type, the ling drum type coupling is widely used at home and abroad. The drum type gear type coupling belongs to the rigid flexible coupling. This product has complete specifications. And to undertake all kinds of non-standard support design and manufacture, good quality, stable use, abide by the contract, timely delivery, reasonable price, the implementation of three guarantees, agent transport.
