Abstract:
1. A method for reducing the presence of ferritic particles in a lubricant employed for the lubrication of a gear unit comprising a plurality of rotary shaft bearings of the type comprising a first bearing contact surface, a second bearing contact surface and a plurality of rotatable bearing members disposed therebetween, said method comprising: placing a ferritic particle collector element of magnetized material adjacent to each of at least two of said plurality of rotary shaft bearings and a path of lubricant flowing to said plurality of rotary shaft bearings; and spacing each of said at least two of said plurality of rotary shaft bearings at a distance from a respective collector element so that corresponding first and second bearing contact surfaces are less than five times the maximum diameter of said first and second bearing contact surfaces.
