To prevent bolt breakage, we need to start from the following aspects:
Choose the right bolt:
Choose the right bolt material and strength grade according to the strength requirements of the application.
Choose the right bolt size according to the hole diameter and thread size of the connector.
Consider the application environment and choose the right surface treatment or anti-corrosion coating.
Install the bolts correctly:
Clean the screw holes and bolt surfaces of the connectors to remove impurities such as oil, rust, etc.
Tighten the bolts according to the specified torque value to avoid being too loose or too tight.
Use washers or anti-skid pads to evenly distribute the pressure to prevent the bolts from loosening.
Check and maintain the bolts regularly:
Check the bolts regularly for looseness, deformation, corrosion, etc.
If abnormal conditions are found, take timely measures, such as tightening the bolts, replacing the bolts, etc.
For bolts used in harsh environments such as vibration and impact, the inspection cycle should be shortened.
Avoid overloading the bolts:
Do not apply a force that exceeds the maximum allowable load of the bolts.
Evenly distribute the load to avoid local overload.
Use limit devices to prevent bolt overload.
Pay attention to the anti-corrosion of bolts:
For bolts used in humid and corrosive environments, appropriate anti-corrosion materials or coatings should be selected.
Check the surface of the bolts regularly, remove rust, and perform anti-corrosion treatment.
Disassemble the bolts correctly:
Use appropriate tools to disassemble the bolts to avoid damage to the bolts or connectors.
For tightened bolts, heating, force and other methods can be used to assist in disassembly.
After disassembly, check whether the bolts and connectors are damaged and replace them if necessary.
In short, preventing bolt breakage requires comprehensive consideration of the selection, installation, maintenance, and use of the bolts. Only by taking preventive measures in each link can the occurrence of bolt breakage accidents be effectively avoided.
