Characteristics of drum type coupling (compared with straight type coupling has the following characteristics)

1. Strong carrying capacity. Under the same outer diameter of the inner gear sleeve and the coupling, the bearing capacity of the drum gear coupling is increased by 15 ~ 20% on average than that of the straight gear coupling.

2. Large amount of angular displacement compensation. When the radial displacement is equal to zero, the allowable angular displacement of the straight gear coupling is 1º, and the allowable angular displacement of the drum gear coupling is 1º30 ", which is increased by 50%. Under the same modulus, number of teeth and tooth width, the drum teeth are larger than the allowable angular displacement of the straight teeth.

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

4, the outer tooth sleeve tooth end is horn shape, so that the inner and outer teeth assembly and disassembly is very convenient.

5, transmission efficiency up to 99.7%. Based on the characteristics of warp, at present, drum teeth have been widely used at home and abroad instead of straight gear coupling.
