First foundation scheme advantage is: when carrying out lubricating oil filling lubrication to rolling element, first the filler opening of the first sealer from first passage is pulled out, then lubricant oil is injected to first passage from here, lubricant oil flows to second channel from first passage, finally flow out from the oil outlet of second channel, because oil outlet is positioned on the inner ring surface of outer ring, after then lubricant oil flows out from oil outlet, flow directly on rolling element, greatly reduce the waste of lubricant oil, after lubrication terminates, the first sealer is arranged on filler opening place.
The second base case that this programme provides is: the cylindrical bearing on rotary cultivator live axle, comprise outer ring and rolling element, described outer ring is provided with first passage and second channel, described second channel runs through outer ring, described first passage comprises filler opening and cecum, described filler opening is positioned at narrow end surface place on outer ring, and cecum is arranged in outer ring; Described second channel intersects with first passage and is communicated with, and second channel comprises opening end and oil outlet, and oil outlet is positioned at the inner ring surface of outer ring, and opening end is positioned on the outer ring surface of outer ring, and described filler opening is provided with the first sealer, and open end is provided with the second sealer.
The advantage of the second base case is: for first foundation scheme, second base case difficulty of processing when processing second channel is less, the second channel of the second base case can directly be holed from the outer ring surface of outer ring, and first foundation scheme can only be processed from inner ring surface, because the size of bearing is usually less, processing second channel seems very difficult, can only be made by casting, but the usual aperture of second channel is less, therefore casting mould comparison is difficult.
Preferred version one: as the preferred version of first foundation scheme or the second base case, described rolling element is provided with groove.When lubricant oil flows to rolling element after oil outlet outflow, parts of lubricating oil remains in groove, when rolling element rotates, lubricant oil in groove is thrown out of, now lubricant oil is directly thrown on the working surface of rolling element and outer ring and inner ring, substantially increase the effective rate of utilization of lubricant oil, simultaneously parts of lubricating oil remains in groove, is conducive to the later stage to lubricate rolling element.
Preferred version two: the another preferred version as first foundation scheme or the second base case: described first sealer is bolt, and bolt can realize quick mounting and dismounting, fast and easy opens and closes the filler opening of first passage.
Preferred version three: the preferred version as first foundation scheme: described second sealer is rubber stopper, and rubber stopper has with low cost, the feature of good sealing effect.
Preferred version four: the preferably preferred version of: be provided with sponge in described groove, sponge can better adsorb more lubricant oil, and when rolling element rotates, sponge contacts with outer ring, and the lubricant oil in sponge is enclosed with on inner ring outside by sponge wiping.This preferred version guarantees that the lubricant oil in sponge outwards runs off gradually, but not has disposablely been run off by lubricant oil in groove, extends the oily time period of bearing.
