Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited to this.
Embodiment:
A kind of oil collecting structure of engine lubrication system, as shown in Figure 1, engine lubrication system includes the bent axle arranged on the engine, and near the lubricating oil pump that bent axle is arranged, lubricating oil pump is installed by the mounting seat arranged on the engine, just the position of lubricating oil pump driving shaft being provided with installing hole 1 in mounting seat, lubricating oil pump driving shaft is arranged in installing hole 1；It is characterized in that, described oil collecting structure is arranged in mounting seat, and oil collecting structure has the oil-collecting passage of connection mounting seat outer surface and installing hole so that the machine oil being arranged in mounting seat outer surface can pass through oil-collecting passage inflow installing hole.
Engine lubrication system is mainly made up of parts such as lubricating oil pump, oil filter, oil radiator, oil sump and collecting filters.Lubricating oil pump provides sufficiently high pressure, it is ensured that carry out force feed and lubricating oil (being mainly machine oil) can circulate in lubricating system.Oil filter is used for the metal filings, mechanical admixture and the oil ageing thing that filter in lubricating oil.Oil radiator is used for reducing the temperature of lubricating oil.The container of oil sump storage lubricating oil.Collecting filter is used for filtering impurity thick in lubricating oil, it is prevented that impurity enters lubricating oil pump.Lubricating system mainly includes force feed, splash lubrication and grease lubrication, and force feed is the lubricating system with certain pressure, machine oil being fed friction surface.Oil droplet that when splash lubrication is to utilize electromotor to work, movement parts splashes or the lubricating system of fog lubrication friction surface.Grease lubrication carrys out the working surface of lubricating detail mainly by the regular grease up of grease fitting.Therefore engine lubrication system is operationally, in lubricating oil pump, (particularly the outer surface of machine oil pump shaft mounting seat) usually has the machine oil splashing, therefore the oil collecting structure of the present embodiment, there is the oil-collecting passage of connection mounting seat outer surface and installing hole, make the machine oil being arranged in mounting seat outer surface can pass through oil-collecting passage and flow into installing hole, the machine oil being splashed to mounting seat outer surface can be introduced in installing hole by this structure, lubricating oil pump driving shaft is lubricated, extends the service life of lubricating oil pump.
In order to better ensure that oil-collecting effect, the oil-collecting mechanism of the present embodiment adopts dual oil-collecting mode to carry out oil-collecting.
Ground floor oil-collecting mode: described oil collecting structure includes the surface of installing hole end, to the first oil through 2 having.First oil through is arranged on directly over installing hole end, facilitates machine oil to flow in installing hole, so, remains in the machine oil in installing hole end outer surface, it is possible to flows into installing hole inner chamber from the first oil through, serve the effect of ground floor oil-collecting.
Described first oil through is caved inward the breach formed by installing hole end face.Owing between the molecule in machine oil, tension force is relatively big, in order to ensure that machine oil can be smoothly through the first oil through, the first oil through is the breach with opening, also functions to the effect of convenient processing simultaneously.
On the outer surface of described installing hole, the position near described first oil through is provided with oil baffle 3, and oil baffle 3 is arranged on the first oil through and closes on the side of bent axle, just can stop the splashing circuit of the machine oil being splashed to machine oil pump shaft mounting seat outer surface.Oil baffle 3 is distributed along the axis direction of installing hole, and upper end obliquely upward, the direction of deviateing the first oil through tilts so that the machine oil of installing hole outer surface can be stopped by oil baffle 3, and is flowed in installing hole by the first oil through.So can stopping more machine oil being splashed to installing hole outer surface, oil baffle tilts obliquely upward so that the machine oil stopped by oil baffle can along the incline direction of oil baffle to dirty.When being embodied as, the side of described oil baffle and the end face of installing hole.The setting of oil baffle enhances the oil-collecting effect of ground floor oil-collecting mode.
Second layer oil-collecting mode: described oil collecting structure also includes just to the surface in the middle part of installing hole in mounting seat, to the second oil through having.Relative to ground floor oil-collecting mode, the machine oil of the outer surface being splashed to mounting seat is more, so in the surface at the middle part of mounting seat to the second oil through having, make the machine oil being splashed to the outer surface of mounting seat can flow into installing hole from the second oil through, serve the effect of second layer oil-collecting, relative to ground floor oil-collecting mode, the effect of second layer oil-collecting becomes apparent from, and introduces the machine oil in installing hole more.
In order to strengthen the effect of second layer oil-collecting,
Being provided with the boss of arc on the outer surface of described mounting seat near the position of the second oil through, formed and surround or partly surround the oil trap having the second oil through, the table top of boss is higher than the position of the second oil through.Making the machine oil that the outer surface of mounting seat is collected, it is possible to be collected in the oil trap that boss surrounds or part encirclement is formed, the machine oil collected in oil trap can pass through the second oil through and flow in installing hole.When being embodied as, the groove face of oil trap can be arranged to outer edge height, middle part low inclined plane, the convenient machine oil collected in oil trap can flow in the second oil through.
Described bent axle and lubricating oil pump adopt gear-type transmission structure to install on the engine.The connection of gear-type transmission structure reduces engine noise better.
What finally illustrate is, above example is only in order to illustrate technical scheme and unrestricted, although the present invention being described in detail with reference to preferred embodiment, it will be understood by those within the art that, technical scheme can be modified or equivalent replacement, without deviating from objective and the scope of technical solution of the present invention, it all should be encompassed in the middle of scope of the presently claimed invention.
