Drum gear couplingspecialty

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

2. Large amount of angular displacement correction.When the radial displacement is zero, the allowable angular displacement of the spur gear coupling is 1ordm. The allowable angular displacement of the barrel gear coupling is 1ordm 30, which is increased by 50%. In the same modulus, number of teeth, and tooth width, the barrel The angular displacement of the profile gear is larger than that of the straight tooth.


3. The barrel-shaped tooth surface improves the contact conditions of the inner and outer teeth. The edge of the straight tooth is squeezed under the angular displacement condition, which avoids the disadvantages of stress concentration, and at the same time improves the friction and wear of the tooth surface, reduces the noise, and has a long maintenance cycle.

4. The tooth end of the outer gear sleeve is in the shape of a trumpet, and the assembly and disassembly of the inner and outer teeth is very convenient.

5. The transmission efficiency is as high as 99.7%.According to the characteristics of the warp, barrel-shaped gears are widely used at home and abroad instead of straight-tooth couplings. UMA has a complete range of barrel-shaped gear couplings and meets the corresponding standards.Due to its high rigidity, softness and inelasticity, barrel-shaped gear couplings are not suitable for machinery with strict requirements on vibration reduction, cushioning and biaxial pairing.
