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.

　　Under normal circumstances, it is required that the two shafts to be connected are completely concentric, and it is impossible to continue to maintain the concentric state during operation. Because of installation errors, bearing wear, force deformation, foundation sinking, etc., the axis produces radial and Angular displacement.The drum gear coupling has the characteristics of compensating the above displacement, reduces the additional load caused by the axis displacement, improves the working stability and reliability of the transmission device, and thus prolongs the service life of the transmission device.

　　In the 1s, the drum gear coupling began to be developed and the standard, the machinery industry standard, was published and implemented for nearly 2 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. In addition, the coupling itself is a vulnerable part and needs to be replaced every XNUMX to XNUMX years, so the market demand is large. It is hoped that each production will increase technical input, update equipment, and produce drum-shaped gear couplings as soon as possible in the market, and make due contributions to our technological development.

　　The drum gear is one of the key parts of the movable rigid coupling-drum gear coupling, which is more mature in the transmission field.The basic structure of the drum-shaped gear coupling is composed of a normal straight-tooth internal gear and a drum-shaped external gear. Its form is equivalent to a spline connection, but it is meshed and connected according to the principle of gear meshing during transmission. The number of teeth is the same, the theoretical transmission ratio is 1:1, and due to the special structure of the drum-shaped external teeth, the radial offset Δα and the angular displacement Δθ between the axes of the drum gears at both ends can be achieved, and the axis of the internal and external gears can also be achieved. The deflection angle is θ, and the carrying capacity is high, the operation is stable, and the work is reliable.
