Abstract
The invention relates to a high-strength anti-corona bolt. The high-strength anti-corona bolt comprises a bolt and a nut, wherein the bolt comprises a rod body and a threaded section, the threaded section is provided with a pin hole I, and the upper end face of the bolt is a spherical surface; the length of an thread in the nut is equal to the length of the threaded section of the bolt, the nut is provided with a pin hole II matching with the pin hole I of the bolt, and the upper end face of the nut is in a circular arc shape. The high-strength anti-corona bolt disclosed by the invention is made from No. 45 steel; the strength of the high-strength anti-corona bolt is improved through thermal treatment; the machining length of the thread is shortened, so that the use amount of materials is reduced, and the production cost is reduced; the contour of the connection part of the bolt and the nut is in smooth transition, so that the possibility of generating the corona is largely reduced; a groove is formed in the middle part of the nut, so that the length of a close pin is shortened, and the installation is convenient; after the close pins of the bolt and the nut are matched, the end faces of the bolt and the nut are leveled, so that the length of the whole bolt is shortened, and the production cost is reduced.
Description
Technical field
The present invention relates to the assembly in a kind of electric power project of transmitting and converting electricity, relate in particular to the anti-corona bolt of a kind of high strength.
Background technique
After common hexagonal headband Pin hole bolt is installed, because thread section length on bolt is longer, the connecting part of nut and thread section is shorter, thereby causes on bolt the thread section utilization ratio not high, and the bolt entire length is elongated, wasted cost of production, have gap between nut and pin, after long-term the use, nut is understood downside pin and is tightened between position loosening, connect insecurely, have potential safety hazard; The end face of bolts and nuts is mostly plane, easily produces the corona befouling environment.
Summary of the invention
The present invention provides a kind of and has reduced material consumption, reduced production costs, is connected firmly, places the anti-corona bolt of high strength of corona in order to overcome the above problems.
Technological scheme of the present invention is: comprise screw bolt and nut, described bolt comprises the body of rod and thread section, and described thread section is provided with pin-and-hole one, and the bolt upper-end surface is sphere; Described nut inner thread length is identical with the length of thread section on bolt, described nut be provided with bolt on the suitable pin-and-hole two of pin-and-hole one, described nut upper-end surface is circular-arc.
Described nut middle part is groove, and described pin-and-hole two is arranged in groove.
The present invention adopts No. 45 steel makings to improve intensity through Overheating Treatment, be processed with the closed pin mounting hole on bolts and nuts, after installation, bolt and nut closed pin relative position is fixed, there do not is the situation of nut loosening, and the processing length of screw thread shortens, reduced the consumption of material, reduced cost of production, screw bolt and nut profile rounding off, greatly reduce the possibility that corona produces, groove is left at the nut middle part, shortened the length of closed pin, be convenient to install, after the bolt and nut closed pin coordinates, the bolt and nut end face is concordant, the bolt entire length shortens, save production cost.
