Technical field
The utility model belongs to the engine lubrication technical field, relates to a kind of lubricating fitting, relates in particular to a kind of lubricating fitting of crankshaft connecting mechanism of motorcycle.
Background technique
Motor is an important component part of motorcycle, and the mobile energy that provides of motorcycle can be provided for it, when high engine speeds running produces heat, need draw machine oil and through oil circuit oil delivery is lubricated and cools off to the motor each several part by oil pump.In-engine crank mechanism comprises crankcase and bent axle, and bent axle is located in the crankcase, is provided with bearing between bent axle and the crankcase, and bent axle is provided with the crank passage, and a side corresponding with the crank passage on the bearing is connected with a disc.At present, need be lubricated and when cooling off in-engine crank mechanism, be to the position of bearings mostly with oil delivery, spray into disc from bearing and casing interstitial site again, machine oil is carried out filtering, play the effect of centrifugal filter by the rotation of disc, simultaneously, this disc can increase engine oil pressure and control machine oil and enters the crank passage, and the connecting rod tip needle roller is lubricated, and structure is comparatively simple.
But, because machine oil flows into disc by the position of bearings, reduced himself oil pressure, make that the pressure when machine oil enters crank pin is lower, the lubrication effect that enters behind the crank passage is also undesirable.In addition, if finish machine oil sprays into disc from bearing process, the external diameter of bearing must be littler than the diameter of disc, because of disc is installed on the crank, size is subjected to certain restriction, can only lubricate and cooling purpose to reach by the external diameter that reduces bearing, this measure makes the specification of bearing be subjected to bigger restriction, is unfavorable for structural design.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed a kind of lubricating fitting that can keep machine oil self oil pressure and the bearing outside diameter size is not had the strict crankshaft connecting mechanism of motorcycle that limits when machine oil flows into disc.
The purpose of this utility model can realize by following technical proposal: a kind of lubricating fitting of crankshaft connecting mechanism of motorcycle, be arranged in the crankshaft connecting mechanism, crankshaft connecting mechanism comprises crankcase and is arranged in the interior bent axle of crankcase, be provided with bearing between described crankcase and the bent axle, bent axle is arranged with a gear outward, opposite side with respect to gear on the described bearing is provided with a disc, it is characterized in that, the lubricating fitting of described crankshaft connecting mechanism of motorcycle comprises oil duct, described oil duct one end is communicated with the filler opening sealing of crankcase, and the other end leads to disc.
When motorcycle engine runs up, machine oil is subjected to the oil pump effect to enter oil duct from the filler opening of crankcase, and flow to the other end of oil duct along oil duct, owing to do not stopped in the flow process of machine oil, the oil pressure that has kept machine oil, make the pressure when machine oil flows to disc by the oil duct the other end remain on higher level, the machine oil after the supercharging that throws away in the disc then has better lubrication effect.
In the lubricating fitting of above-mentioned crankshaft connecting mechanism of motorcycle, described oil duct comprises crankcase oil duct of being located in the crankcase and the crankshaft oil gallery that is arranged on the bent axle, crankcase oil duct one end is communicated with the filler opening sealing, the other end extends between said gear and the bearing, described crankshaft oil gallery one end communicates with the crankcase oil duct, and the other end leads to disc.
In the lubricating fitting of above-mentioned crankshaft connecting mechanism of motorcycle, described bent axle is provided with a crank passage, and the position of this crank passage is corresponding with disc.Disc after by rotation machine oil being carried out filtering and supercharging gets rid of it into the crank passage, and the connecting rod tip needle roller is lubricated.
In the lubricating fitting of above-mentioned crankshaft connecting mechanism of motorcycle, described disc is sealedly attached on the bearing, and and bearing between be drive fit.
In the lubricating fitting of above-mentioned crankshaft connecting mechanism of motorcycle, described bearing is provided with dust cover.
In the lubricating fitting of above-mentioned crankshaft connecting mechanism of motorcycle, offer a circular groove on the described gear, described circular groove place is provided with an O type circle.Dust cover by O type circle on the gear and bearing seals the gap on the oil duct, makes that the circulation of machine oil in oil duct is more smooth and easy.
Compared with prior art, the lubricating fitting of this crankshaft connecting mechanism of motorcycle has the following advantages:
1, the lubricating fitting of this crankshaft connecting mechanism of motorcycle is the oil duct that is arranged in the crankshaft connecting mechanism, the oil delivery that this oil duct can flow out from crankcase is to the disc place, the machine oil circulation is smooth and easy in this process, utilize the oil pressure of machine oil itself fully, can reach better lubrication effect after making machine oil by the disc supercharging.
2, insert because of do not flow through bearing and casing of machine oil, make this lubricating fitting reduce greatly, reduced cost the specification requirement of bearing.
