Alignment Procedure When we perform alignment on any machine, we should all follow the set procedure, a simple and effective procedure for doing shaft alignment. First we perform the Pre-Alignment Checks; • Safety procedures • Lockout/tag out of the machine • Visual inspection of the foundation, ground and baseplate • Clean-up, remove rust, scale, paint…
Backlash – Coupling What is backlash? Backlash in unintended movement that occurs when rotating the shafts during an alignment. It is most often caused by looseness in the coupling. Backlash is most often caused by looseness in the coupling. On misaligned machines, backlash can cause measurements error. In order to eliminate measurement errors, backlash must…
Coupling Types On the basis of shaft alignment. Couplings can be classified into two types; Rigid Coupling Flexible Coupling Rigid Coupling It is used to connect two shafts having no misalignment, ideally co-axial shaft. They are further classified into following types; Sleeve or Muff Coupling Clamp or Compression Coupling Flange Coupling Sleeve Coupling is one of…
Effects of Misalignment Five most common negative effects misalignment can have on your machinery. Seal Failure: Mechanical seals are very expensive, and when one fails, fluid leaks can adversely affect other machine components. Bearing Failure: In addition to the replacement cost of bearings, you can also suffer damage to other components, with an even…
