NGCL type drum gear coupling with brake wheel

NGCL type with brake wheelDrum gear couplingFeatures (compared with straight gear couplings, it has the following features):

1. Strong carrying capacity.Under the same outer diameter of the inner gear sleeve and the large outer diameter of the coupling, the carrying capacity of the NGCL drum gear coupling with brake wheel 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 1°, and 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 tooth 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 squeezing the edge of the straight tooth 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. High transmission efficiency.

6. The tooth spacing is small, the allowable relative radial displacement is small, the structure is compact, and the moment of inertia is small. It is suitable for the occasions matching with brake shoe 

7. It is allowed to rotate in the forward and reverse directions, and the external gear sleeve on either side can be used as the active input end, and the nominal torque can be transmitted from 400 to 100000 N·m. 

8. In order to enhance the lubrication and sealing effect, reduce the number of parts, and improve the reliability of operation, it is particularly recommended to use the integral structure type of the sealing end cover and the inner gear ring as a whole.
