Inspection and repair on SAWA gearbox

Inspection and repair on SAWA gearbox

  • SAWA gearbox
  • Input=___ rpm / ____ KW
  • Belgium

Scope of work:

We performed an inspection and repair on a gearbox SAWA.


This client from Belgium came to us with this SAWA . We inspected the gearbox and performed a repair. After a succesful testrun we shipped the gearbox back to the client.

The state of the gearbox can be considered unacceptable.

This conclusion based on:

- The wear on the bearings
- Tooth impression of the gear of the 1st axle
- The matt and gray discoloration

The wear on the bearings is probably due to the exceeding of the recommended running hours.

The tooth impression is as yet unknown. A further inspection will have to give a definite answer.

The matt and gray discoloration (pinion 3rd axis) is a sign of surface weakening, this is probably due to an over-angle bearing pattern of the tooth flanks, this is possible due to lower damage.

Recommendations

- Renew bearings
- Renew the 1st axle sprocket and at least regrind the second axle sprocket
- Check the toothing for cracks by means of Magnaflux
