Inspection and repair project on ZPMC GFH1600.16.A1A-00 gearbox

Scope of work:

We performed an inspection and repair on a gearbox ZPMC GFH1600.16.A1A-00.

GBS International got this ZPMC GFH1600.16.A1A-00 gear unit in our workshop in The Netherlands. After inspecting the gearbox, we did a complete overhaul and testing. After our review department was done, we send the gear unit back to our client.

Recommendations after visual inspection:

Verify gearbox geometry and dimensions of bearing pockets on horizontal boring machine. Upper casing should be adjusted without the use of the dowel pins. Results of these measurements will determine the next step of this thoroughly inspection. ? Adjust axial clearance, between bearing covers, during re-assembly of the gearbox. Perform a test run of gearbox.

Shaft sealing:

The maximum circumferential speed of the input shaft seal surface is (at idle speed) relative high and therefore it is recommended to increase the shaft seal hardness to prevent any oil leakages caused by a worn shaft surface. A modification of the shaft seal design of the input shaft can be realized by laser cladding, (ceramic) coating or the use of hardened wear sleeves
