Features of XINLAN drum gear coupling

Drum toothCouplingThe features are as follows:
1. 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 on average 15-20% higher than that of the straight gear coupling.
2. Large angular displacement compensation.When the radial displacement is equal to zero, the allowable angular displacement of the spur gear coupling is 1o, and the allowable angular displacement of the drum gear coupling is 1o30', 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.
3. The drum-shaped tooth surface 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 at the same time improves the friction and wear of the tooth surface, and reduces Noise, long maintenance period.
4. 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.
5. The transmission efficiency is as high as 99.7%.The curvature radius of the bulge curve is proportional to the single-sided thinning of the internal tooth, so the bulge circle radius should be as large as possible.The radius of curvature of the bulge curve is proportional to the single-sided thinning of the internal tooth, that is, it is related to the meshing gap of the tooth. Insufficient thinning may cause interference, and excessive thinning will weaken the strength of the tooth, and the backlash will be large. .
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 angular displacement conditions, and improves tooth surface friction at the same time , Wear conditions, reduce noise, and 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.
