Drum gear couplingThe tooth surface of the outer gear sleeve is drum-shaped, which can overcome the jamming phenomenon of the tooth end caused by the shaft skew and offset.Under certain inclined angle parts, the tooth surface contact condition is improved, and the coaxiality tolerance when connecting two shafts is increased; under the same working conditions, the load-bearing capacity is 15% higher than that of ordinary straight tooth couplings~ 20%.
Because the drum gear coupling has good axis offset compensation performance, and has the advantages of compact structure, high load capacity, high efficiency, and long service life, it is gradually replacing the straight gear coupling and is widely used in Heavy machinery and metallurgical machinery.
