The utility model relates to a U-shaped plate spring coupling with large torque and large deflection, which belongs to the field of transmission machinery. The coupling consists of a coupling, a U-shaped plate spring, a pressing plate, a cushion plate and a bolt. The characteristic of the coupling is that the angle of each group of U-shaped plate springs is 90 degrees alternately overlapped, and the middle cushion plate is located at the periphery of the coupling, and the square frame is formed by connecting the bolt with the convex claws of the two sides of the coupling, so as to realize the U-shaped between the two coupling sections. Elastic transmission of leaf spring. It has the advantages of reliable operation, large load-bearing capacity and can be used in various working conditions. It can be used for transmission from less than 1 kW to more than 10,000 kW. It has a wide range of applications, no lubrication, no friction and transmission efficiency of over 98%. It has good vibration absorption and damping characteristics. When it is loaded, the relative torsion angle can reach 30 degrees, and the shape size is about 1/2 to 1/3 smaller than the ordinary elastic coupling of the same kind. Cost can be reduced by 1/3 to 1/4. It does not need accurate alignment of two axes. It is simple and convenient. It can be widely used in large, medium and small mechanical engineering, ship, civil, military and other transmission fields.
