Optimization of highly loaded cross couplings in case of uniform distribution of specific loads

One of the ways to improve the quality of products of the machine-building industry is to increase the use of progressive structural materials in machine-building rolling from low-alloy steel bent shaped and precision profiles, etc., which, in turn, requires improving the design and operational reliability of the main load-bearing elements and mechanisms of production process equipment, including rolling mills, blooming mills, cardan shafts and others, in the design of which the transfer of torque to the working bodies is carried out by means of quick couplings, called high-loaded cross couplings, capable of transmitting at low speeds torques over 300 kNm at a significant misalignment of the connected shafts (up to 3-5 mm) and angles of inclination of the fork axis with respect to the axis of the coupling blade up to 8-10.
