Crushing press lubrication system has device for evacuating lubricant outside crushing press, so lubricant does not mix with crushed material

摘要

A system for lubricating bearings and rollers includes a device for evacuating the lubricant outside the crushing press. The press has a fixed central axle (2) with at least one longitudinal hollow (19) mounted with at least two main roller bearings, respectively proximal (17) and distal (18), and has at least two compression rollers (10, 11) connected to one end of the axle : The device for evacuating the lubricant include a device for evacuating the lubricant from the bearings and from each compression roller, and comprise a bypass channel (21) connecting the longitudinal hollow in the axle to the distal bearing. A secondary flow zone (24), comprising an evacuation channel (29) starting from the proximal bearing, connects the two bearings. The means of evacuating the lubricant from the compression rollers are a bypass channel (23) connecting the distal end of the axle to one of the rollers. At least one of the rollers has a lubricant inlet channel (30), connecting the bypass channel to the bearing (15) of the compression roller. This inlet channel has a longitudinal inlet branch and a median transverse branch. At least one of the compression rollers has a lubricant outlet channel (31) connecting a bearing (15) in the roller to a collector (32). The outlet channel has two transverse branches connecting the bearing of the roller to a longitudinal outlet branch. The inlet and outlet channels are in the same section of the press.
