Leroy-Somer — Coupling alignment of two shafts
Installation
From a Leroy-Somer service manual — check it applies to your exact model before use.
Before you start
- Deviations exceeding 0.05 mm indicate the need for axial or radial adjustment
Procedure
- Provisionally assemble both coupling halves
- Adjust the parallel plane of both shafts using a gauge
- Measure the distance between the two coupling surfaces at one point on the circumference
- Rotate them 90°, 180° and 270° in relation to this initial position and measure each time
- The difference between the two extremes of value x must not exceed 0.05 mm for standard couplings
- To check concentricity, mount 2 gauges and slowly turn both shafts
Tools required
- Gauges Amazon
