New motivation! New upgrade!

With the large-scale introduction of high-precision equipment by Henan Flag Crane

Production and R&D strength continues to increase

Several automatic drum tooth production lines were put into use

"Drum Gear Coupling"

Innovation in a small accessory

Greatly improve the quality and service life of crane products

01

product description:

The drum gear coupling belongs to the rigid-flexible coupling, which has the ability to compensate the axial deviation of radial, axial and angular directions. Drum-shaped tooth couplings are widely used at home and abroad as a common coupling for heavy-duty shaft transmission.

02

Features:

1. Strong carrying capacity. Under the same outer diameter of the inner gear sleeve and the maximum outer diameter of the coupling, the bearing capacity of the drum gear coupling is on average 15-20% higher than that of the straight gear coupling.

2. Large amount of angular displacement compensation. Under the same modulus, number of teeth, and tooth width, the angular displacement of the drum teeth is larger than that of the straight teeth.

3. The drum-shaped tooth surface improves the contact conditions of the inner and outer teeth, improves the friction and wear conditions of the tooth surface, reduces the noise, and has a long maintenance period.

4. The tooth end of the outer tooth 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%.

03

Suitable place:  

It is often used for shafting transmission under low-speed and heavy-load conditions, such as the shafting transmission of gas turbines. transmission.
