Abstract
The utility model discloses a crank pin used for a motorcycle engine. The crank pin comprises a crank pin body (2) with through holes (1), an oil inlet (3) and an oil outlet A (4) are formed in the crank pin body (2) in a dislocated and corresponding mode, the positions inside the through holes (1) at the two ends of the crank pin body (2) are respectively provided with a filtering device, and at least one class of filtering devices are in the through holes, between the oil inlet (3) and the oil outlet A (4), of the crank body (2). The crank pin used for the motorcycle engine has the advantages of being simple in structure and high in reliability, the crank pin used for the motorcycle engine can filter the impurities in engine oil in the crank pin, abrasion to a needle-rolling shaft of the impurities is reduced, and the service life of a crank shaft is prolonged.
Description
Technical field
The utility model relates to a kind of crank pin, and is particularly a kind of for the crank pin on motorcycle engine.
Background technique
At present, fierceness day by day along with the motorcycle industry competition, the client is also more and more harsher to the quality requirement of motorcycle engine, lubrication system is as the blood circulation system of motor, promote the turbidity test of engine lubrication machine oil, to greatly improve the working life of motor, win the larger market space.
Existing crankshaft of motorcycle produces the larger reason of fault, mainly because motor is on-stream, its internal motion spare interacts and produces metal impurities, impurity enters each lubrication system by machine oil, because common crank pin is the straight hole oil duct, the metal impurities in machine oil will directly enter needle bearing by the crank pin oil duct, cause needle bearing to produce inordinate wear because of impurity, cause bent axle to break down, greatly shortened working life.
The model utility content
The purpose of this utility model just is to provide a kind of can the filtration machine oil, keep the oil product turbidity test for the crank pin on motorcycle engine.
The purpose of this utility model is to realize by such technological scheme, a kind of for the crank pin on motorcycle engine, comprise the crank pin body with through hole, corresponding and shifted to install filler opening and oil outlet A on the crank pin body, at the two ends of described crank pin body and be positioned at through hole and be respectively arranged with filtrating equipment, in the through hole of described crank pin body and between filler opening and oil outlet A, be provided with first level filtering device at least.
Wherein, described filtrating equipment is a dividing plate, on described dividing plate, is provided with at least one oil-through hole, and described oil-through hole is positioned at the top, middle part of dividing plate or/and bottom.
Better for the lubrication effect that makes needle bearing, on described crank pin body and with oil outlet A corresponding part, be provided with oil outlet B.
Owing to having adopted technique scheme, the utlity model has advantage simple in structure, that reliability is high, adopt it the impurity in the machine oil that enters in crank pin can be filtered, reduced the wearing and tearing of impurity to the needle roller axle, improve the working life of bent axle.
The accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail; but the utility model is not limited to these mode of executions; any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, a kind of for the crank pin on motorcycle engine, comprise the crank pin body 2 with through hole 1, corresponding and shifted to install filler opening 3 and oil outlet A4 on crank pin body 2, at the two ends of described crank pin body 2 and be positioned at through hole 1 and be respectively arranged with filtrating equipment, in the through hole 1 of described crank pin body 2 and between filler opening 3 and oil outlet A4, be provided with first level filtering device at least.
Described filtrating equipment is a dividing plate 5, on described dividing plate 4, is provided with at least one oil-through hole 6, and described oil-through hole 6 is positioned at the top, middle part of dividing plate 5 or/and bottom.
On described crank pin body 2 and with oil outlet A4 corresponding part, be provided with oil outlet B7.
The utility model is like this work: when machine oil, from filler opening 3, enter into crankpin body 2 interior after, due to crankpin do not stop transport moving, under the effect of centrifugal force and dividing plate 4, impurity in machine oil just is blocked in the below of dividing plate 4, and the clean machine oil after being filtered just flows out by oil-through hole 6, by the oil-through hole 6 on the dividing plate 5 at the oil outlet A on crankpin body 2, oil outlet B and two ends, flow to needle bearing again, needle bearing is lubricated.
In the utility model, the number that is arranged on the dividing plate between oil inlet hole 3 and oil outlet 4A can according to actual needs, arrange voluntarily; The number of oil-through hole 6 and size also can set up on their own according to engine displacement.
Claims (3)
1. one kind for the crank pin on motorcycle engine, comprise the crank pin body (2) with through hole (1), at crank pin body (2), go up correspondence and shifted to install filler opening (3) and oil outlet A(4), it is characterized in that: at the two ends of described crank pin body (2) and be positioned at through hole (1) and be respectively arranged with filtrating equipment, in the through hole (1) of described crank pin body (2) and be positioned at filler opening (3) and oil outlet A(4) between be provided with first level filtering device at least.
2. as claimed in claim 1 for the crank pin on motorcycle engine, it is characterized in that: described filtrating equipment is a dividing plate (5), on described dividing plate (5), be provided with at least one oil-through hole (6), described oil-through hole (6) is positioned at the top, middle part of dividing plate (5) or/and bottom.
3. as claimed in claim 2 for the crank pin on motorcycle engine, it is characterized in that: at described crank pin body (2) upper and with oil outlet A(4) corresponding part is provided with oil outlet B(7).
