Abstract
The utility model relates to a perforated floating sleeve sliding bearing, consisting of an outer bearing, a floating sleeve and a shaft journal. The utility model is characterized in that the column surface of the floating sleeve is drilled to form through holes for lubricating grease to flow through, the arrangement positions of the through holes are symmetrical along axial direction and circumferential direction, and the boundaries of the through holes and outer surface of the floating sleeve adopt chamfering transition on the edges. The utility model can improve the problem limited by structure or volume of an original floating sleeve bearing that the inner(outer) bearing lubrication is deficient in oil supply. The utility model guarantees the inner part and the outer part of the whole floating sleeve bearing obtain sufficient lubricating during work, decreases the temperature of the bearing, reduces the wear speed of the bearing, and prolongs the service life of the bearing.
Description
Technical field
The utility model relates to a kind of plain bearing arrangement that can rotate freely floating bushing that is equipped with, and especially can better solve because after the introducing of floating bushing was divided into two former bearing, there was the lubrication problem of fuel feeding deficiency in interior outer bearing.
Background technique
At present, the application of floating bushing sliding bearing in mechanical transmission is extensive day by day, and the structure of existing floating bushing sliding bearing has opening and two kinds of openings not.The introducing of floating bushing can reduce the relative sliding velocity of former sliding bearing, thereby reduces frictional power loss, makes the temperature of bearing be more prone to control, prolongs bearing working life.But simultaneously, because the introducing of floating bushing is divided into two former sliding bearing, be divided into inside and outside two bearings of floating bushing, in some special construction such as roller bit floating ring sliding bearing, the lubrication oil supply problem of inner bearing or outer bearing becomes the principal contradiction that influences the bearing integral performance again like this.
In some special constructions, as the rock bit bearing structure, present oil storage bag lubrication system can guarantee the fuel feeding of oil film in the floating ring bearing, outer bearing is owing to separated by floating bushing, lubricant medium can only enter the contact area from the two ends of floating bushing, can't guarantee in the work to lubricate fully, reduce the overall performance of bearing.
Summary of the invention
The purpose of this utility model is to provide cellular type floating bushing sliding bearing, can better solve the problem of floating bushing sliding bearing lubricating fuel feeding deficiency in some special constructions.
The utility model finishes the improvement of structure on the basis of former floating bushing sliding bearing, on the basis of former floating bushing, increased some run through in the through hole of outer bearing, make lubricant oil or lubricating grease to flow to outer bearing from inner bearing through these through holes, perhaps flow to inner bearing from outer bearing, preliminary identification through unit experiment, the improvement that this scheme is effective the problem of former floating ring bearing lubrication oil supply deficiency, can play the effect that prolongs the floating ring bearing life-span.
The technological scheme that its technical problem that solves the utility model adopts is: on former floating bushing cylinder, but the through hole that flows of symmetric arrangement supplying lubricating grease along the circumferential direction, the size in hole, quantity and position can be determined flexibly according to floating bushing diameter and width etc., then internally the influence of outer bearing oil film loaded area is bigger too much for Kong Taida or quantity, reduce bearing load carrying capacity, Kong Taixiao or quantity very little then the lubricant medium flow do not reach intended purposes, adopt the chamfering transition on the limit that hole and floating bushing inner and outer surface have a common boundary.When bearing rotates, lubricant medium can by this through hole (or outer) bearing in lubricant medium replenishes fully flow to lubricant medium shortage outside (or interior) bearing, improve the lubricating status of bearing on the one hand, flowing of lubricant medium also can play a role to the heat of taking away the friction surface generation on the other hand, thereby reduce the rate of wear of bearing on the whole, prolong the working life of bearing.
The beneficial effects of the utility model are, can improve because the problem of interior (outward) the bearing lubrication fuel feeding deficiency of the former floating ring bearing of structure or volume restrictions, guarantee all to obtain lubricating fully inside and outside the whole at work floating ring bearing, reduce bearing temperature, reduce bearing wear speed, prolong the working life of bearing.
Description of drawings
Fig. 1 is assembly structure of the present utility model and lubricant medium runner schematic representation.
Fig. 2 is a perforation formula floating bushing part 3 D stereo schematic representation.
Among the figure, 1. bearing outer ring (or bearing support);
2. floating bushing;
3. lubricant medium is generally fluid or semifluid;
4. axle journal;
5. the through hole on the floating bushing;
6. lubricant medium storage area sprue, lubricant medium by the reserve that is contained in somewhere on the axle journal from this sprue inlet passage 7;
7. lubricant medium passage, lubricant medium enters the bearing working zone by this passage.
Embodiment
In Fig. 1, there are inside and outside two sliding bearing friction pairs, it is the external friction pair that bearing 1 and floating bushing 2 are formed, the interior friction pair that floating bushing 2 and axle journal 4 are formed, lubricant medium 3 enters interior friction pair from reserve through axle journal 4 center holes 6 and passage 7, thereby friction pair can obtain lubricated preferably in making.And the direct supplemental lubrication medium of the secondary because existence of floating bushing of external friction, if hole 5 does not exist, then lubricant medium can only flow out from the two ends of interior friction pair earlier, two ends from the external friction pair enter lubricated external friction pair then, the lubricant medium of external friction pair in this case obviously can not get replenishing fully, makes that the secondary lubricating status of external friction is not good enough.By design of the present utility model, but circumferentially process the through hole 5 that supplying lubricating grease flows at floating bushing, for flowing to the external friction pair from interior friction pair, lubricant medium provides express passway, the lubricant medium of external friction pair like this can obtain replenishing more fully, improving the lubricating status of external friction pair, thereby improve the service behaviour and the working life of whole floating bushing sliding bearing.
In Fig. 2, the via arrangement position is vertically with circumferentially symmetrical on the floating bushing, and quantity is determined according to floating bushing diameter and width size.
Claims (3)
1. cellular type floating bushing sliding bearing is arranged, form, it is characterized in that, but on the cylinder of floating bushing, be drilled with the through hole that supplying lubricating grease flows by outer bearing, floating bushing, axle journal.
2. floating bushing sliding bearing according to claim 1 is characterized in that: the via arrangement position is vertically with circumferentially symmetrical on the floating bushing cylinder.
3. floating bushing sliding bearing according to claim 1 is characterized in that, adopts the chamfering transition on the limit that described through hole and floating bushing inner and outer surface have a common boundary.
