CHEMINEER gearbox Inspection and repair project

Scope of work:

We performed an inspection and repair on a gearbox CHEMINEER 7-HTN-25 .

GBS International got this Chemineer 7-HTN-25 gear unit in our workshop in Belgium. After inspecting the gearbox, we did a complete overhaul and testing. After our review department was done, we send the gearbox back to our client.

The following findings were made during the removal of the gearbox:

- Incoming coupling is 0.08 mm loose on the shaft
- Incoming coupling rubbers damaged
- 1st stage gear (Z151) tooth broken off
- 1st stage spline pinion shaft at the tooth heads damaged
- Outgoing shaft entered at the oil seals
