Drum-shaped gear couplings have also made certain developments in recent years. According to the specific development direction, we have summarized some of its general development trends.

　　1. Gradually develop from single use to supporting use.The current drum-shaped gear coupling is no longer used alone as before, but has begun to be used as a complete set. This is also a development trend of the drum-shaped gear coupling in the future.

　　2. The requirements for quality of accessories are getting higher and higher.The requirements of the current drum gear coupling in use have been improved, so the requirements for the accuracy of the drum gear coupling itself have also been improved, and the requirements for the quality of accessories have also been improved. .

　　From the above development trend, we can see that the development of the drum gear coupling is moving in a better direction, and if it has been along this direction, it will definitely go further.

　　The drum gear coupling is composed of an internal gear ring with the same number of teeth and a flange half coupling with external gears.The external teeth are divided into straight teeth and drum teeth. The so-called drum teeth means that the external teeth are made into a spherical surface. The spherical surface is on the gear axis. The tooth side clearance is larger than that of ordinary gears. Drum-shaped gear couplings can be used. Allows larger angular displacement (compared to the straight tooth coupling), which can improve the contact conditions of the teeth, increase the torque transmission capacity, and prolong the service life
