VIBFEM Gearless exciter with significantly improved lubrication system upper bearings - when the exciter operates in inclined position( standard operating position is at 45 degrees) will provide reliable oil sump lubrication for all bearings and therefore better bearing life and improved reliability. Another factor is that it does not have gears which when wearing during impact condition, contaminate the oil with metal particles and increase the oil temperature which leads to oil degradation. Modifications will also allow to reduce weight and cost of exciter fabrication.
