The characteristics of drum gear couplings (compared with straight gear couplings) are as follows:
1. The angular displacement compensation is large. When the radial displacement is equal to zero, the allowable angular displacement of the spur gear coupling is 1°; while the allowable angular displacement of the drum gear coupling is 1°; 30″, an increase of 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;
2. 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 drum gear coupling is 15-20 on average higher than that of the straight gear coupling;
3. The drum-shaped tooth surface improves the contact conditions of the inner and outer teeth, avoids the edge extrusion of the straight tooth tooth under the condition of angular displacement, and the stress-concentrated end. At the same time, it improves the friction and wear of the tooth surface and reduces The noise is reduced, and the maintenance period is long;
4. The transmission efficiency is as high as 99.7%;
5. 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.
