Drum gear coupling is a new type of gear coupling developed on the basis of spur gear coupling, digesting and absorbing foreign advanced technology.It is composed of an outer gear sleeve with a drum-shaped tooth thickness and a matching inner gear ring that connects two shafts. It is suitable for heavy-duty and two-axis transmission that requires axis displacement compensation.

　　With the continuous development of technology, more and more drum-shaped gear couplings require high-precision, heavy-duty hard tooth surface.The main parts of the heavy-duty high-precision drum gear coupling are made of low-carbon alloy high-quality steel, which is milled and ground after heat treatment, with high machining accuracy, and the depth of the heat-treated carburized layer is guaranteed by numerical control equipment.

　　In the XNUMXs, the drum gear coupling began to be developed and the standard, the machinery industry standard, was published and implemented for nearly XNUMX years. It has basically replaced the original spur gear coupling. Because of its compact structure and large load-bearing capacity, The moment of inertia is small, and it has a certain axis offset compensation performance, so it is widely used in various mechanical transmissions.
