Tribological Studies Regarding the Crude Rapeseed Oil Press
MetadataShow full item record
The aim of this paper is to present a tribology test conducted on crude rapeseed oil press. The experiments were carried out with four-ball machine. The oil was tested at speed of 1000 rot/min and loads of 140 N and 200 N. Times of the test were 1200, 2400 and 3600 seconds. During the action of the 140 N load, the friction force has an almost linear increase, unlike the friction force recorded at the load of 200 N, when it was noticed a sharp increase in the range of 0 to 800 seconds, followed then by a stabilization of the friction force.
