Gear failed during production. (No spare, emergency repair).
We started by the disassemble pinion assembly, repair teeth by welding, machine and hand finish teeth; and reassemble. After all the cracks were removed, there were not many teeth left. The base
material was analyzed and a weld procedure was produced.
All teeth were welded and post weld heat treatment was performed by procedure. This gear was then machined on the O.D. diameter and faces.
This gear was then hand finished using special gauges and templates. Complete
inspection showed no defects and tooth location and size almost perfect.
On-Site assembly and installation by skilled mechanics.
Alignment was checked. Tooth engagement was fine tuned and cement kiln was put back into production. Gear repair successful.
