Abstract
Motorcycle engine crank, including the crank body, this internal horizontal oilhole and oblique oil duct of being equipped with of crank, just the oil -out of horizontal oilhole lies in the right side of the oil inlet of oblique oil duct, left side that crank body inherence is located horizontal oilhole is equipped with first oil in proper order from the right side to a left side stifled with second oil, just between to one side the oil inlet of oil duct is located that first oil is stifled and blocks up with second oil, be equipped with the oilhole on first oil is stifled, and first oil is stifled and the oil -out of horizontal oilhole between have a first filter chamber, first oil is stifled to have the second filter chamber with second oil between blocking up. The utility model discloses can carry out the secondary filter separation to the impurity of machine oil, reduce the wearing and tearing of impurity to crank pin, bearing and connecting rod effectively, prolong bent axle life.
Description
Technical field
The utility model relates to motorcycle engine, particularly relates to a kind of motorcycle engine crank.
Background technique
Present motorcycle engine crankshaft produces most reasons of fault, main in engine running, the metal impurities that the interaction of interior metal movement parts produces, metal impurities pump into oil duct with machine oil by oil pump and enter lubrication system, because common crank is straight hole oil duct, the metal impurities in machine oil directly will enter needle bearing by oil duct, thus cause needle bearing accelerated wear test, cause crankshaft fault, shorten the life-span of motor.
Therefore, be necessary to develop a kind of new motorcycle engine crankshaft.
Summary of the invention
The purpose of this utility model is to provide a kind of motorcycle engine crank, can carry out secondary filter separation to the impurity of machine oil, to reduce the wearing and tearing of impurity to crank pin, needle bearing and connecting rod, extends bent axle working life.
Motorcycle engine crank of the present invention, comprises crank body, be provided with horizontal oilhole and oblique oil duct, and the oil outlet of horizontal oilhole is positioned at the right side of the filler opening of oblique oil duct in described crank body;
The left side that described crank body inherence is positioned at horizontal oilhole is provided with that the first oil is stifled and the second oil is stifled from right to left successively, and the filler opening of described oblique oil duct at the first oil stifled and the second oil stifled between;
Described first oil blocks and is provided with oil-through hole, and the first oil stifled with the oil outlet of horizontal oilhole between there is the first filtering cavity, between stifled and the second oil of described first oil is stifled, there is the second filtering cavity.
After machine oil enters crank body from horizontal oilhole, due to crank do not stop transport dynamic, under the effect that centrifugal force and the first oil block up, metal impurities in machine oil will be blocked in the first oily the first filtering cavity blocked up between horizontal oilhole, machine oil after filtration flows into the second filtering cavity by oil-through hole again, under the effect that centrifugal force and the second oil block up, machine oil carries out secondary filter by the second filtering cavity again, make the metal impurities in machine oil stay in the second filtering cavity, the machine oil clean through twice filtration flows out finally by the oblique oil duct in crank body.
The internal diameter of the oil-through hole that the first oil blocks is less than the internal diameter of horizontal oilhole, is convenient to keep oil pressure at constant range.
The utility model has the following advantages: it can carry out secondary filter separation to the impurity in machine oil, thus effectively reduces the wearing and tearing of impurity to crank pin, needle bearing and connecting rod, extends the working life of bent axle; And structure is simple, compact, easily processes, cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein: 1, crank body, the 2, first oil is stifled, and the 3, second oil is stifled, 4, tiltedly oil duct, and 5, horizontal oilhole, the 6, first filtering cavity, the 7, second filtering cavity, 8, oil-through hole; Arrow in figure represents the flow direction of machine oil.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Motorcycle engine crank as shown in Figure 1, comprises crank body 1, is provided with horizontal oilhole 5 and oblique oil duct 4 in described crank body 1, and the oil outlet of horizontal oilhole 5 is positioned at the right side of the filler opening of oblique oil duct 4.The left side that described crank body 1 inherence is positioned at horizontal oilhole 5 is provided with the first oil stifled 2 and the second oil stifled 3 from right to left successively, and the filler opening of described oblique oil duct 4 is between the first oil stifled 2 and the second oil stifled 3.Described first oil stifled 2 is provided with oil-through hole 8, and the first oily blocking up has the first filtering cavity 6 between 2 and the oil outlet of horizontal oilhole 5, and described first oil stifled 2 and the second oil have the second filtering cavity 7 between blocking up 3.
After machine oil enters crank body 1 from horizontal oilhole 5, due to crank do not stop transport dynamic, under centrifugal force and the first oil block up the effect of 2, metal impurities in machine oil will be blocked in stifled the first filtering cavity 6 between 2 and horizontal oilhole 5 of the first oil, machine oil after filtration flows into the second filtering cavity 7 by oil-through hole 8 again, under centrifugal force and the second oil block up the effect of 3, machine oil carries out secondary filter by the second filtering cavity 7 again, make the metal impurities in machine oil stay in the second filtering cavity 7, the machine oil clean through twice filtration flows out finally by the oblique oil duct 4 in crank body 1.
As shown in Figure 1, the internal diameter of the oil-through hole 8 on described first oil stifled 2 is less than the internal diameter of horizontal oilhole 5, so that keep oil pressure at constant range.
Claims (2)
