Taken
practical-analytical research as a result village farm in the technique applicable roller
bearings service for the period impact provider main factors and their extension methods
determined :
Main exit Reasons : Analysis results this showed that the village farm in the technique
roller bearings main from work exit reasons of the following consists of :
o
Abrasive Feeding : Dusty and hard of particles lubrication to the material enter
progress as a result bearing of elements to be eaten ( from work) came out observed in 45% of
bearings ).
o
Corrosion : Moisture and aggressive environment under the influence bearing of
the material rust process ( from work) came out observed in 28% of bearings ).
o
Wrong lubrication Lower good quality lubrication from materials use, lubrication
interval violation or enough in quantity of lubrication absence ( from work) came out observed in
17% of bearings ).
o
Excessive
Loads and blows : Technique heavy under the circumstances
performance as a result appearance to be too much outside loads and impacts ( from work) came
out observed in 10% of bearings ).
Service the deadline extension Methods : observation, analysis and literature review
