Inspection and repair of Chemineer 6-XHTN-60 gearbox

CHEMINEER gearbox
6-XHTN-60
Input=___ rpm / ____ KW

Scope of work:

We performed an inspection and repair on a gearbox CHEMINEER 6-XHTN-60.

We got this Chemineer 6-XHTN-60 gearbox in our shop in The Netherlands. After a thorough inspection, we did a complete overhaul and testing. After our quality control department was done, we shippen the gear unit back to our client.

Gearbox has been running for about 5 hours (without oil cooler and with supplied oil pump). Leakage detected at outgoing oil seal. (for this, oil must therefore enter the standpipe).

Probably due to foaming, oil level and leaking oil seal. Second test:
GBS oil pump connected, outgoing cover disassembled and the outgoing bearing held in position by means of adjustment tools.

GBS oil pump switched on (180 rpm 0.4 bar as supplied with the oil pump) gearbox is not yet running. No leakage was found. Gearbox input revs slowly boosted no leakage until 1500rpm was achieved.
