Alignment - alignment of the axes of the motor shaft and the driven mechanism. It seems like a small thing, but misalignment is one of the main causes of vibration, wear of bearings and couplings. Let's look at why this is important.
What is the threat of misalignment
- Increased vibration of the entire unit.
- Accelerated wear of the engine and mechanism bearings.
- Destruction of the coupling.
- Fatigue cracks of the shaft.
- Increased energy consumption.
Even a small displacement of the axes creates alternating loads that gradually destroy the nodes.
Types of misalignment
| Type | Description |
|---|---|
| Parallel | Axes are parallel, but offset |
| Angle | Axes at an angle to each other friend |
| Combined | Combination of both |
How alignment is performed
Precise alignment is done using dial indicators or laser devices. Work order:
- Check the condition of the foundation and supports.
- Eliminate the “soft foot” (uneven fit).
- Measure the displacement and fracture of the axes.
- Adjust with shims and engine displacement.
Alignment must be performed after each installation of the engine or replacing bearings. If vibration appears after the repair, the first thing to do is check the alignment and balancing.
