How to pick the right bolt size for a load?
1 First, identify the load case 2 Determine the necessary clamping force in the joint 3 Choose the smallest bolt diameter that can support the clamp load 4 Choose an effective bolt securing method 5 Decide on the most appropriate tightening method
Why are the bolts on my boom not torqued?
The drive mechanism relies on bolted joints to secure the boom to the drive motor. These bolts are clearly critical but often only torqued. Our service ensures they are originally tightened to the correct pre-load and is used periodically to re-measure in-service tension.
What do you need to know about boltstress?
We provide Bolt Stress, Flange Stress, Tightening Torque, Tensioner Pressure and Gasket Seating Stress calculations for Mills, Pressure Vessels, Heat Exchangers, Slew Ring Bearings, Cylinder Heads, Structural Beams and Turbines. Many designers overlook the maintainability of bolted joints.
What should you do if you have a bolt failure?
Ensure original bolt tension is correct Regular re-monitoring ensure long term mill health Unique tooling and skills reduces construction time by 75% Grinding mills have critical fasteners that hold the structure together. If they have incorrect pre-load and loosen the ramifications are dire.
Is there a way to prevent bolts from breaking?
Often, cylindrical protectors or metal plates are used to prevent bolt breakage, but these can be considered ‘home solutions’ which cannot be adopted at an industrial level. Here are five ways in which bolts can break – and what you can do to insulate yourself from the problem.
Why are some of the bolts on my fork breaking?
In applications where the bolts face large amounts of vibration, it can cause an uneven amount of stress on the bolts, causing them to break. For example, in a shift fork, vibrations cause either the loosening of bolts or even complete breakage, which can result in a total loss of control.
What causes car bolts to deteriorate over time?
Bolts in automobile parts are more susceptible to chemical corrosion where bolts can be exposed to engine oil leaks or other fluid leaks, therefore causing them to deteriorate over time. Incompatible metal corrosion or galvanic corrosion is comparatively rare but can happen in mechanical, mining, or construction applications.
What happens if you break a bolts on a rotary machine?
Bolts breaking can put any piece of equipment in danger of malfunctioning or causing injury in the close vicinity when used on a rotary assembly or mechanical equipment. Although the problem is not encountered often, individuals and companies place added emphasis on ensuring that their equipment or machine does not succumb to ‘broken bolts’.
