2results about How to "Increased torsional rigidity" patented technology

The application provides a core wire assembly for a guide wire, a guide wire and a guide wire system. The core wire assembly comprises a tubular element and a shaping element. A plurality of cut grooves are arranged on the side wall of the tubular element. The plurality of cut grooves are arranged along an axial direction parallel to the central axis of the tubular element and are offset from each other along a circumferential direction around the central axis. At least part of the plurality of cut grooves extends along the circumferential direction. The tubular element is sleeved on the outside of the shaping element. The core wire assembly of the application can greatly increase the torsional rigidity of the core wire assembly without changing the surface properties of the existing core wire assembly, so that the types of guide wires available for operators to choose are more diverse to meet various surgical needs.

Split type transmission shaft relates to transmission structure technical field, including coaxial parallel rotation connection in the middle transmission shaft and universal transmission shaft in axle housing, the middle transmission shaft and universal transmission shaft are connected through meshing support structure, the other end of the middle transmission shaft is connected differential gear, the other end of universal transmission shaft is connected end transmission assembly.The utility model solves the problem that the length of universal transmission shaft of the rear drive axle of large harvester in traditional technology is lengthened, and the transmission efficiency is reduced due to the torsional deformation in the transmission process caused by the insufficient rigidity, and the left and right universal transmission shafts are not universal, which leads to the problems of large mold development investment, difficult manufacturing process turnover protection, difficult to ensure the straightness of processing, poor dynamic balance, easy to wear, high straightening cost and low production efficiency.
