Problems solved by technology

[0002] In the existing industries that use transmission couplings, universal couplings are mainly composed of cross shafts and fork heads to compensate the angle between shafts and transmit torque, especially in rolling mills in the steel industry, such as Universal couplings used in section steel rolling mills, high-speed wire rods, bars, plates and other production rolling lines have high load-bearing torque, but the existing universal joint shafts have short service life, high cost, difficult maintenance and replacement, affecting production efficiency, and It is a key component for metallurgical rolling steel, lifting equipment, transportation machinery and other enterprise equipment
[0003] 1. The existing universal coupling is mainly composed of two forks and a cross package (cross shaft and bearing). During use, the fork is easily deformed under the action of the transmitted torque. The reason is that The fork is stressed at two points, and the stress concentration is prone to fracture or deformation of the bearing inside.
[0004] 2. In terms of the structure of the existing coupling, the compensation angle is limited
[0005] 3. The currently used universal coupling is difficult to install during assembly, the processing technology is complicated, and the production cycle is long. When the operating speed exceeds 300 rpm, dynamic balancing is required.
