5 results about "Torsion strength" patented technology

To provide a motor pump that can ensure the torsional strength of the mounting section of the main shaft to which the impeller is attached, while suppressing the generation of fluid vortices and backflow downstream of the main shaft. [Solution] The motor pump comprises a first impeller, a main shaft to which the first impeller is fixed, a motor for rotating the first impeller, and a casing that houses the first impeller and the main shaft and has a fluid passage through which fluid flows. The downstream end of the main shaft is positioned in the fluid passage, and the main shaft has a mounting portion to which the first impeller is attached, and a smaller diameter portion positioned downstream of the mounting portion and having a smaller diameter than the mounting portion.

This invention discloses a winding correction device for alloy wire stranded wire, relating to the technical field of alloy wire stranded wire production equipment. It includes a frame, with a frame between two main shafts. Rotary disks are fixedly mounted on the main shafts on both sides of the frame, and a stranding bow is installed between the two rotating disks. Both ends of the frame are rotatably connected to the main shafts. A twisting assembly is provided at both the inlet and outlet ends of the stranding bow, applying a torsional force to the wire passing through it. It also includes a detection unit configured to correct the torsional strength of the stranded wire based on the detected torsional torque of the wire through the twisting assembly. By incorporating a winding correction device including a twisting assembly and real-time monitoring of the wire torsional torque by the detection unit, the technical problem of traditional equipment being unable to control the tension of the stranded wire is effectively solved, significantly improving the quality of the stranded wire product.

A golf shoe with an upper and a sole assembly connected to the upper. The sole assembly includes a midsole and an outsole. At least one of the midsole or outsole comprises (i) a foamed material and (ii) a structure integrated with or embedded in the foamed material. The structure comprises a different material than the foamed material. The structure comprises a spineless structure with one or more members extending between a medial side and a lateral side of the midsole or the outsole to enhance a lateral support and a torsional strength or stiffness of the midsole or outsole. The structure has a shape or profile that is different than a shape or profile of a bottom of a subject's foot.

The utility model discloses an anti-twist jumping-out mechanism for a cylinder belt, which relates to textile after-finishing equipment and comprises depended wheel components and a belt jumping-out prevention component, the depended wheel components are symmetrically arranged on two sides of the cylinder belt, and the belt jumping-out prevention component is fixed on a cylinder swing arm; a bearing and a depended wheel mandrel are arranged in the depended wheel, and the two ends of the depended wheel mandrel are fixedly connected with the upper pressing plate and the lower pressing plate through fixing bolts; the belt jumping-out prevention assembly comprises a rocker arm, a pressing wheel assembly, a guide sleeve and a fixing shaft, the inner arc of the rocker arm is matched with the diameter of a cylinder driving belt wheel, the pressing wheel assembly comprises two pressing wheels and a connecting plate, bearings and eccentric shafts are arranged in the pressing wheels, the two ends of the connecting plate are fixed to the eccentric shafts respectively, and the other ends of the eccentric shafts are fixed to the rocker arm. The torsional strength of the depended wheel assembly is improved, stress deformation is prevented, and it is guaranteed that a belt runs stably; and a belt jumping-out prevention assembly is additionally arranged, and the belt is pressed through a pressing wheel, so that the belt is effectively prevented from jumping out of a belt groove.

A high-torque threaded connection is provided with male and female thread forms consisting of wedge threads with high shear strength and high torsional strength. The radius of curvature r1 of the base of the load flank of the first thread 111, located at the end of the male thread form 11 associated with the tip, is not less than the thread height Th×0.14, and more preferably not less than Th×0.16, to improve the shear strength of the first thread 111.In addition, the thread pitch can be reduced to increase the number of threads to increase the contact area for load flanks, or only the radius of curvature of the base of the load flank of the first thread located at the end of the male thread form associated with the tip can be increased, and a smaller curvature diameter can be provided for the other portions in order to increase the contact area for the load flanks, thus maintaining high resistance to torsional stress.
