S.Y. Adix

M & A Engineering solve the propeller shaft alignment problem on the prestigious S.Y. Adix, at the Pendennis Shipyard, Falmouth.

 

 

 S.Y. Adix

Alignment errors between the gearbox coupling and inboard and outboard Cutlass Bearing Housings were the suspected cause of excessive vibration and bearing wear.

M & A designed and manufactured special optical target holders that located in either end of the bearing housings, and concentric with the gearbox coupling.

 

 

           

Target mounted on the gearbox coupling, and alignment check in progress

The alignment results indicated the inboard housing was indeed misaligned with the centreline of the prop shaft.
M & A line bored the Ø140mm x 410mm long housing bore to correct the alignment error.

 

 

                                                                            

Machining In progress on the Inboard Cutlass Bearing Housing

On completion of the repair, the Pendennis engineers commented that the alignment was now so perfect; that -
"The propeller shaft can now be easily turned by hand".
