RS1 Turbo Shaft Straightening

The RS1 is the tool dedicated to checking and correcting the linearity of turbine shafts and rotors, representing a fundamental preliminary step before balancing.

Main function

This equipment allows you to:

• check the straightness of the shaft or rotor
• identify any deformation or eccentricity
• correct anomalies through the integrated system

Structure and components

The RS1 consists of:

• two centers for securing the component
• precision dial indicator for measurement
• integrated correction press for straightening

The system allows accurate and immediate control of the component geometry.

Inspection procedure

1. Fixing: the shaft or rotor is positioned between the centers
2. Manual rotation: the component is rotated manually
3. Reading: the indicator detects any deviation from linearity

Operating tolerances

The system allows a clear assessment of the component condition:

• ≤ 0,005 mm
  → compliant component
• between 0,005 mm and 0,20 mm
  → recoverable component (correction required)
• ≥ 0,20 mm
  → component to be discarded

Linearity correction

When the component falls within the recoverable range:

• the deformation point is identified
• the shaft is positioned correctly
• the integrated press is used for straightening

This makes it possible to bring the component back within acceptable tolerances.

Operating capacity

• Maximum component length: 180 mm
• compatible with most turbine shafts and rotors

The RS1 is a mandatory step before balancing.

Why it is essential

Balancing a non-linear component is ineffective:

• it generates unstable results
• it increases processing time
• it compromises final quality

Benefits

• correct preparation of the component
• greater efficiency in subsequent stages
• reduction of rework

In summary

The RS1 guarantees:

• precise control of linearity
• the possibility of recovering components
• improvement of the entire overhaul process
