Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of crankcase mechanism.
Background technique
Crankcase is the cavity structure that holds bent axle, be usually located at the bottom of motor, the bent axle in engine operation in crankcase rotates around axle center, and bent axle is connected with connecting rod, effect by connecting rod converts the to-and-fro motion of piston to the rotation of self, thereby drives vehicle movement.Because motor is in the process of running up, piston is worked under the condition of high temperature, high pressure, high speed, therefore the piston of motor, in running, enters piston face by the crankshaft rotating band engine oil in crankcase and makes its cooling heat dissipation, keeps lubricating between piston ring and cylinder block simultaneously.At present, need to be lubricated when cooling in-engine crank mechanism, to position of bearings mostly by oil delivery, from bearing and casing interstitial site, spray into disc again, but because machine oil flows into disc by position of bearings, thereby reduced himself oil pressure, the pressure while making machine oil enter crank pin is lower, the lubrication effect entering after crank passage is also undesirable.
For the problem of above-mentioned existence, people have made various improvement to crankcase, and some has also applied for patent, for example, in Chinese patent literature data, disclose a kind of lubricating fitting [application number: 201020277882.3 of crankshaft connecting mechanism of motorcycle; Notice of authorization number: CN201723271U], the lubricating fitting of this crankshaft connecting mechanism of motorcycle, be arranged in crankshaft connecting mechanism, crankshaft connecting mechanism comprises and crankcase and be arranged in the bent axle in crankcase is provided with bearing between crankcase and bent axle, and bent axle is arranged with a gear outward, opposite side with respect to gear on bearing is provided with a disc, the lubricating fitting of crankshaft connecting mechanism of motorcycle comprises oil duct, and oil duct one end is communicated with the filler opening sealing of crankcase, and the other end leads to disc.
The lubricating fitting of above-mentioned a kind of crankshaft connecting mechanism of motorcycle, its lubricating fitting is the oil duct being arranged in crankshaft connecting mechanism, this oil duct can be by the oil delivery flowing out from crankcase to disc place, improved to a certain extent lubrication effect, but the effect due to centrifugal force, machine oil in throwing disc can only get rid of into crank passage, connecting rod tip needle roller is lubricated, can not carry out direct lubrication to the piston of working under the condition of high temperature, therefore the lubrication effect of the lubricating fitting of this crankshaft connecting mechanism of motorcycle is unsatisfactory, thereby can affect whole life-span of using of motor and stability thereof etc.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, and a kind of lubricated, good cooling results is provided, and the crankcase mechanism of long service life.
The purpose of this utility model can realize by following technical proposal: a kind of crankcase mechanism, comprise cylinder, crankcase and be arranged in the bent axle in crankcase, described cylinder is positioned at crankcase, between described crankcase and bent axle, be provided with bearing, on described bent axle, be connected with a connecting rod, the other end of described connecting rod is connected with the piston in being arranged on cylinder, it is characterized in that, on described crankcase, offer oil duct, described oil duct one end is filler opening, the other end of oil duct leads to bearing, on described crankcase, offer nozzle opening, one end of described nozzle opening is connected with oil duct, the other end of nozzle opening is between piston and bent axle and towards piston setting, the diameter of described nozzle opening is less than the diameter of oil duct.
This crankcase mechanism utilizes the nozzle opening diameter of offering on crankcase to be less than oil duct diameter, and make between it mineralization pressure poor, under entering the effect of oil duct intrinsic pressure, oil is injected into pistons work district by nozzle opening, thereby reduce the temperature of piston when hot operation, make the film lubrication improvement of terms between piston ring and cylinder wall, and reduce the problems such as turbidity test that carbon distribution that surface produces because of excess Temperature causes affecting motor inner chamber, extend the physical life of motor and stability etc.
In above-mentioned a kind of crankcase mechanism, described nozzle opening is the straight hole being obliquely installed.
In above-mentioned a kind of crankcase mechanism, described oil duct diameter is 6mm, and the diameter of described nozzle opening is 1mm, and the angle of nozzle opening and bent axle is 45 degree.
As another situation, in above-mentioned a kind of crankcase mechanism, described nozzle opening is that horn mouth horn-like and that it has is towards piston setting.
Compared with prior art, the piston serviceability temperature of this crankcase mechanism reduces, and area carbon reduces, and surveys turbidity test and improve in motor, has longer physical life and stability.
