Articulated bolt is a specially designed mechanical connector primarily used to withstand vibration loads or in scenarios requiring high lateral stability. The following are its core features and descriptions:
1. Structural characteristics
The hinge hole bolts have basically the same size to ensure a tight connection. The front thread is used for fastening, while the rear end of the rod is responsible for positioning and shear resistance.
2. Working principle
Lateral load: It is directly supported by the shear strength of the screw itself and the extrusion strength of the hole wall, without relying on the frictional force generated by pre tightening force.
Axial load: The bearing capacity is the same as that of ordinary bolts, mainly relying on threaded connections.
Therefore, its pre tightening force requirement is relatively small, but it is necessary to simultaneously verify the shear and compression strength.
3. Difference from ordinary bolts
• Matching method: Ordinary bolt holes are 0.5-1mm larger than the screw, which is non matching; The hinged bolt is a transitional fit.
• Force mechanism: Ordinary bolts rely on the frictional force generated by pre tightening force to resist lateral loads, requiring a large pre tightening force; The hinged bolt is directly subjected to shear and compression forces.
Function: It combines positioning and fastening, while ordinary bolts are only used for fastening.
4. Application scenarios
Mainly used in fields with frequent vibrations or high lateral loads, such as metallurgical equipment, transmission systems, textile machinery, etc.
In summary, hinge hole bolts have significantly improved the reliability of lateral load-bearing through structural design and optimization of stress mechanisms, making them suitable for industrial scenarios with strict stability requirements.
