Strong carrying capacity. Under the same outer diameter of the inner gear sleeve and the maximum outer diameter of the coupling, the carrying capacity of the Curved-tooth Gear Couplings is on average 15-20% higher than that of the straight gear coupling;
The angular displacement compensation is large. When the radial displacement is equal to zero, the allowable angular displacement of the spur gear coupling is 1º, while the allowable angular displacement of the Curved-tooth Gear Couplings is 1º30”, which is increased by 50%, at the same modulus and number of teeth. , Under the tooth width, the allowable angular displacement of the drum tooth is greater than that of the straight tooth;
The drum tooth surface improves the contact conditions of the inner and outer teeth, avoiding the edge extrusion of the straight tooth under the condition of angular displacement. The disadvantage of stress concentration also improves tooth surface friction and wear conditions, reduces noise, and has a long maintenance cycle;
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.
The transmission efficiency is as high as 99.7%. Based on the characteristics of warp, drum-shaped gears have generally been substituted for straight-tooth couplings at home and abroad. The drum-shaped gear coupling produced by UMA has a complete range of specifications and conforms to the corresponding standards. Drum-shaped gear couplings are rigid, flexible, and inelastic, so they are not suitable for machinery that requires damping, buffering, and two-axis alignment.
