Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in fig. 1-5, the utility model provides a coaxial anti-torsion shear-bearing structural member, which comprises a shear-bearing hollow shaft 4, a sleeve 5, a bolt 6, a nut 7 and a shaft-stop plate 8, wherein the sleeve 5 is sleeved on the bolt 6, the shear-bearing hollow shaft 4 is respectively arranged at the upper end and the lower end of the sleeve 5, and the shear-bearing hollow shaft 4 and the sleeve 5 are connected and pre-tightened through the bolt 6 and the nut 7.
Bearing and shearing hollow shaft 4 one side is equipped with the draw-in groove, installs only board 8 in the draw-in groove, and bearing and shearing hollow shaft 4 passes through only board 8 to be fixed on the component, prevents its rotation.
And mounting holes are formed in two ends of the shaft stopping plate 8, the mounting holes are fixed on the first component 1 (or the second component 2) through screws, and the mounting holes of the shaft stopping plate 8 are used for preventing the shear bearing hollow shaft 4 from being twisted.
As shown in FIG. 3, the present invention is used to connect a first member 1 and a second member 2 when in use. The first component 1 and the second component 2 are respectively provided with two groups of coaxial shaft holes, a bolt 6 penetrates through the shaft holes, the shear bearing hollow shaft 4 and the sleeve 5 are installed on the bolt 6, the sleeve 5 tightly pushes the upper shear bearing hollow shaft 4 and the lower shear bearing hollow shaft 4, and the upper shear bearing hollow shaft and the lower shear bearing hollow shaft are connected and pre-tightened through the bolt 6 and a nut 7. When bearing torsional load, two piece upper and lower bearing shear hollow shafts can pass through bolt and sleeve pipe transmission load each other, guarantee to bear simultaneously.
According to the structure of the connecting end of the component, a group of coaxial anti-torsion shear-bearing structural components can be provided with a multi-section connecting structure, as shown in fig. 4, in each section of connecting structure, a sleeve 5 and a shear-bearing hollow shaft 4 are installed at intervals and are connected and pre-tightened through a bolt 6 and a nut 7.
