Hi,

just contact one of the below mentioned bucket wheel drive gearbox manufacturers:

Siemens (former Flender): http://www.flender.com/ or http://www.siemens.com/

Eickhoff: www.eickhoff-bochum.de/

...

Noise analyzis of a BW-drive mostely depends on the type of design (bevel gear has a higher noise level than worm gear...)

Normally you should have 83 +/-2 dB at 1m distance. (theoretically at no-load tests, but on site everything is on a higher sound level... cutting noise, material impacts, chute sealings, bend pulley and than you can't say what comes from the gearbox and what from the other components) ■

Thanks for the help guys I'll let you know how I go.

Does anyone have access to a reclaimer gearbox that they can measure for me? ■

So far no luck. Any ideas? ■

Have got the following dimensions:

3.0m x 1.5m x 1.5m (L x W x H)

Does this sound realistic?

Also, does anyone have an estimation for the rpm of the slowest shaft in the gearbox? ■
