Abstract
The utility model discloses a reservoir type oil retaining bearing. A spiral groove is manufactured on the surface of the non-running top circle of the oil retaining bearing, and the interference fit of the bearing and the bearing saddle bore is utilized to form a sealed oil reservoir, which achieves the effect of the sufficient oil self complement to the oil retaining bearing, makes the bearing keep the favorable operating state for a long term, and extends the service life.
Description
The utility model belongs to a kind of oil-impregnated bearing that adopts means of a powder metallurgy technique to make.
Find article---" design of sintering metal oil-impregnated bearing " of " powder metallurgy science and technology " first phase in 1981 publication of Hangzhou powder metallurgy research institute in May, 1981 publication, the structure of oil-impregnated bearing described in the literary composition (the 28th page--31 pages), its store oil--repairing mechanism generally all is positioned at the bearing outside or end face, but the repairing groove only in the part than small size, store oil is also less, and therefore the repairing to bearing is restricted.In addition, the bearing that has has difform groove on running surface, like this, has reduced the running area of contact of bearing, has strengthened wearing and tearing; The also easy direct-axis slime flux of lubricant oil increases oil consumption and greasy dirt.
The purpose of this utility model is to avoid the deficiency on the prior art, and develops a kind of band oil reservoir formula oil-impregnated bearing, can reach oil-impregnated bearing fully from the effect of repairing.
Task of the present utility model can be finished by following measure: with spiral chute of processing on the outer round surface of the non-running of general powder metallurgy oil-impregnated bearing matrix 1, when this bearing was packed bearing support into, its interference fit can form the spiral chute of a sealing.Wherein a place communicates with oil hole on the bearing support, after the oiling, promptly forms a spiral oil reservoir, and at ordinary times, oil hole is sealed.
The bearing both ends of the surface are not led at two of this bearing outside surface spiral chute 2, and a bit of distance is still arranged, and about 4---5 millimeters, can avoid oily direct-axis slime flux.
Accompanying drawing is the shape schematic representation of band oil reservoir formula oil-impregnated bearing.
Embodiment of the present utility model:
Accompanying drawing is that general powder metallurgy oil-impregnated bearing processes for band oil reservoir formula oil-impregnated bearing.Oil-impregnated bearing matrix 1 among the figure, general oil content is not more than 30%, and for prolonging the working life of bearing, it is very necessary to add repairing mechanism.Spiral chute 2 among the figure, are that machining forms on the outer round surface of the non-running of oil-impregnated bearing, 3 millimeters of groove widths, 1 millimeter of groove depth, 4 millimeters of two distance between bearing both ends of the surface of groove are when this bearing is packed bearing support into, spiral chute and bearing saddle bore interference fit promptly form a spiral oil reservoir that seals.The tank filler sleeve that is positioned at bearing support top is communicated with spiral chute, behind the notes lubricant oil, seals.Regularly open shutoff, the compensation oil consumption is till the bearing hole wearing and tearing are overproof.
The utility model has the following advantages compared to existing technology:
1, band oil reservoir formula oiliness bearing is owing to having a spiral oil reservoir, so can be effectively from mending lubricating oil on the vast area of bearing.
2, the both ends of the surface of bearing are not led at this bearing spiral fluted two, therefore can form with bearing block the spiral oil reservoir of sealing, and advantage is to be unlikely the direct-axis oil spilling, than bearing fuel-efficient again the reduce greasy dirt of oil groove at the running face.
3, above-mentioned repairing mechanism, lubricant oil system supplies with slidingsurface by the bearing matrix with the filtering state, has improved the turbidity test of lubricant oil, helps the use of bearing.
4, the oil groove distribution area of this bearing is wide, and is favourable to the bearing heat radiation.
In a word, band oil reservoir formula oil-impregnated bearing has more perfect store oil---the repairing structure, and effective from repairing, can keep good operating condition for a long time, so, long service life.
Claims (2)
1, a kind of band oil reservoir formula oil-impregnated bearing is made of powder metallurgy oil-impregnated bearing, it is characterized in that the outer round surface of this bearing matrix 1 has spiral chute 2, cooperates with bearing saddle bore, forms the spiral oil reservoir of a sealing.
2, band oil reservoir formula oil-impregnated bearing according to claim 1 is characterized in that still there is a bit of distance at two of the spiral chute 2 on this bearing top circle surface with the bearing both ends of the surface.
