Drum gear coupling features:

　　1. The transmission efficiency of the drum gear coupling is as high as 99.7.

　　2. The drum-shaped gear coupling has strong carrying capacity.The angular displacement compensation is large.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 allowable angular displacement of the drum gear is larger than that of the straight tooth.

　　3. The tooth end of the outer gear sleeve of the drum-shaped gear coupling is in the shape of a horn, which makes the assembly and disassembly of the inner and outer gears very convenient.

　　4. The drum-shaped tooth surface of the drum-shaped gear coupling improves the contact conditions of the inner and outer teeth, avoids the disadvantages of spur tooth end edge extrusion and stress concentration under the condition of angular displacement, and improves the tooth surface at the same time The friction and wear conditions reduce the noise and the maintenance cycle is long.
