Alignment and measurements

• Laser alignment
• Machine alignment
• Rotating equipment
• Shaft alignment
• Bore measurements
• Straightness measurement
• Propulsion / stern tube measurements

In every situation, the most efficient energy transfer will occur if the two connected shafts are co-linear, the shafts behave as if they were one structure. When shafts are misaligned, forces are generated in the coupling. Any deviation in offset or angle will inevitably mean that the shaft will try to find a common axis of rotation. Energy will be lost in the coupling and increased loads will be placed on any mechanical components which provide for rotation, seals, bearing housing, etc. Misalignment manifests itself in five interrelated problems.

• Increased vibration
• Increased energy loss
• Increased load on bearings, seals and other mechanical components
• Lifecycle reduction
• Resonance in components
