Pertanyaan Umum
What are the common causes of bolt fracture and how to prevent them?
Common causes: insufficient or excessive preload, fatigue loads, thread damage, corrosion, and improper material selection. Prevention: tighten to the specified value with a torque wrench, check and re-tighten regularly, use anti-loosening measures on critical parts, and avoid use beyond service life.
How to detect wear on shaft parts?
Measure the journal diameter with a micrometer and compare with the original dimension; roundness and cylindricity deviation should be ≤0.02mm; check surface roughness with a roughness tester; repair (spray coating/electroplating) or replace if scratches, pitting or dimensional deviations exceed tolerance.
What are the torque requirements for fastener installation?
Must tighten with a calibrated torque wrench to the torque values specified in the design documents; high-strength bolts (grade 8.8 and above) use the torque method or angle method in two steps (initial and final tightening); mark after tightening for easy loosening inspection.
