Description

Technical Field

[0001] The utility model belongs to the technical field of couplings, in particular to a novel drum-shaped gear coupling. Background Art

[0002] Drum gear coupling is a common rigid-flexible coupling with strong load-bearing capacity. The drum-shaped tooth surface improves the contact condition of the external teeth, avoiding the disadvantages of straight tooth edge extrusion and stress concentration under angular displacement conditions. At the same time, it improves the friction and wear conditions of the tooth surface, reduces noise, and has the advantages of a long maintenance cycle. It has a wide range of applications.

[0004] In the actual production of couplings, the separate connecting ring must ensure that it cooperates with the inner gear ring and ensures the connection with the connecting flange at the reducer end, so its conventional shape is a part with a T-shaped (flange-shaped) cross-section. This shape of part makes its material utilization rate low during production. At the same time, it is affected by its own overall weight, making assembly more laborious. Utility Model Content
