Appin Colliery part of BHP Billition, located just south of Sydney, were upgrading their drift conveyer in late 2001, part of this upgrade included installing a new 3 MW drive system to replace the existing 2 MW drive which would drive a larger head pulleyt and increase the belt speed form X m/s to Y m/s.
However, they had a problem with the existing 2 MW gearbox prior to the upgrading schedule and required a 2MW gearbox which had the ability to be converted to a 3 MW gearbox and provide the required speed belt speed. PHD designed and suppled a ‘custom’ gearbox for this application. The gearbox was installed at XYZ in the 2MW configuration running at a Y belt speed, this was converted in August 2001 to the 3 MW configuration running at the desired X m/s belt speed.
This conversion process involved the removal of the gearbox from site at Appin Colliery and transfer to a workshop. During which stage te first two motion shafts were replaced with new gearing to accommodated the new 3 MW motor and the gearbox was completely stripped, cleaned, inspected and reassembled within 72 hours.
PHD undertook all the design of the gearbox including the design of the helical geared input shaft which is designed such that under full load the teeth maintain a desirable gear mesh pattern.
