What are the characteristics of the drum gear coupling?

In a wide variety of couplings, drum toothed couplings have the advantages of small and medium-sized, large transmission torque, strong ability to absorb connection errors, and high-quality durability, and are the most common components for connecting two drive shafts in medium and heavy machinery equipment. Compared with the straight gear coupling, it has the following characteristics:

1) Strong bearing capacity.

2) Large amount of angular displacement compensation.

3) The drum tooth surface improves the contact standard of the inner and outer teeth, prevents the extrusion molding of the end edge of the straight teeth under the angular displacement standard, and the shortcomings of the stress, in addition, improves the friction and damage of the tooth surface, reduces the noise, and the maintenance period is long;

4) The end of the outer gear sleeve is like a sound horn, making the installation and disassembly of the inner and outer teeth very convenient.

5) Transmission system efficiency of 99.7%.

According to the above characteristics, drum teeth have been widely used in the world to replace straight gear couplings. Drum gear coupling stiffness is large, flexible, non-elastic, so it is not suitable for shock absorption, caching and two-axis alignment requirements are very strict industrial equipment.
