Its advantages are simple structure, good lubricating, low noise and vibration, saving lubricating oil and less pollution.
Description
The text of dividing an application
The application is the applying date: on December 12nd, 2002, and application number: 02148513.5, denomination of invention: the dividing an application of internal-combustion engine forced lubricating system, and attached original application file one cover and patent application prove one.
Technical field
The present invention relates to a kind of internal-combustion engine forced lubricating system, especially relate to the shelves oil groove in a kind of internal-combustion engine pressure lubrication.
Background technique
1, the present forced lubricating system of known middle-size and small-size internal-combustion engine is lubricant oil to be injected the internal-combustion engine position that respectively rubs with certain pressure be lubricated under the effect of oil pump.Because the high speed operation of oil pump, in lubrication system, will there be certain pressure and temperature, just need to be equipped with parts such as corresponding cooler, pressure valve, safety valve, scavenger valve thereupon, when internal combustion engine, cool off, work such as pressure limiting, oil return, so cause the lubricating structure relative complex of internal-combustion engine, improve the manufacturing and the operating cost of internal-combustion engine, and increased the cost of maintenance and maintenance.
Though 2, middle-size and small-size internal-combustion engine also uses oil pump as pressure lubrication as 165 series, 175 series and series such as 180,190, but mostly being, the friction position of internal body splashes or oil droplet or oil mist lubrication, therefore exist each friction surface and lubricate insecure problem because of low on fuel causes, because the low on fuel of friction surface, the friction at friction position and the vibration and the noise of main frame have been increased again, this not only can the increasing combustion engine internal power consumption, and can make the working surface rapid wearing of each part.
Summary of the invention
The object of the invention: the oil groove of the shelves in the pressure lubrication a kind of simple in structure, economical and practical is provided.
The present invention is the technological scheme that achieves the above object:
Shelves oil groove in a kind of internal-combustion engine pressure lubrication in the gear chamber that a pair of cam timing gear that is meshed and crankshaft timing gear are contained in body, is forced lubricant oil to deliver in camshaft bearing and the crankshaft bearing.
The present invention adopts the advantage after the technique scheme:
The present invention does not change the structure of internal-combustion engine, utilize running up of cam timing gear and crankshaft timing gear that lubricant oil is forced to keeping off in the oil groove, the crankshaft bearing hole is located and place, camshaft bearing hole with lubricant oil is forced to deliver to, lubricant oil is entered in the body with certain flow, replace oil pump to force fuel feeding so close running with the ability to speak of cam timing gear and crankshaft timing gear, not only simplify the structure, and can also reduce the manufacturing cost and use cost of internal-combustion engine, lubricate or cleaning, cooling, reduce friction, resistance, improve durability, fully improve the mechanical efficiency of kinetic energy transmission.
Description of drawings
Below in conjunction with accompanying drawing embodiments of the invention are described in further detail.
Fig. 1 is the structural representation that internal-combustion engine is removed gear chamber cover.
Fig. 2 is the A-A sectional structure schematic representation of Fig. 1.
Embodiment
Shelves oil groove in a kind of internal-combustion engine pressure lubrication shown in Fig. 1-2, comprise body 1, a pair of cam timing gear 5 that is meshed and crankshaft timing gear 3 are contained in the axle head of camshaft and bent axle 7 respectively, and be arranged in the gear chamber of body 1, the gear chamber cover sealing is installed in the sidepiece of body 1, by running up of cam timing gear 5 and crankshaft timing gear 3, force to deliver to lubricant oil in the retaining oil groove 2 and deliver in camshaft bearing and the crankshaft bearing 8.Sidepiece at the tooth rim of cam timing gear 5 and crankshaft timing gear 3 is provided with retaining oil groove 2, and this retaining oil groove 2 is made of with the oil baffle 9 that is installed on the body timing gear bearing support 4 body 1 timing gear bearing support 4, and this oil baffle 9 is seen and be Figure 2 shows that
Font is on one side it is fixedly connected on the body 1 timing gear bearing support 4 and constitutes the retaining oil groove 2 of shaped as frames with body timing gear bearing support 4.When cam timing gear 5 and crankshaft timing gear 3 are contained in the gear cavity that falls in of body 1, then oil baffle 9 is "-" font, be fixed on the body timing gear bearing support 4, retaining oil groove 2 with timing gear bearing support 4 formation shaped as frames, this retaining oil groove 2 is positioned at cam timing gear 5 or gear, chain, one sidepiece of rotation direction or tooth rim portion, and extend to two gear meshing places along the periphery of crankshaft timing gear 3, when a pair of timing gear run up, lubricant oil is along the flank of a pair of timing gear, and the flank by crankshaft timing gear 3 gets rid of most lubricant oil on retaining oil groove 2, most of lubricant oil upwards transports under the effect of high speed centrifugation power etc., the lubricant oil of fraction then gets rid of in timing gear both sides and its engagement place, flows in the camshaft bearing downwards in its action of gravity.The present invention is not owing to change the interior structure of gear chamber, the running that makes full use of the lubricated timing gear of a pair of original needs is as oil pump, lubricant oil is forced to deliver in the camshaft bearing and crankshaft bearing 8 on the body, fuel delivery abundance not only, and noise, vibration and the frictional force of minimizing gear, and be installed in bent axle 7 on the cooperation of suction depressor 6 under, lubricant oil is forced to send into crankshaft bearing 8 places, become the channel that lubricant oil is provided in a large number to the gear chamber that needs confession lubricant oil originally.
Retaining oil groove 2 also can be used for the lubricated of gear-box, drive chain case or cleans, lowers the temperature, reduces friction, resistance, raising durability, fully improves the mechanical efficiency of kinetic energy transmission; So retaining oil groove 2, oil baffle 9 also have " ", " " font or " ",
Font is located by connecting or load, casting, processing constitute retaining oil groove 2 on plate or wall 4, post, prism, object.Under the effect of row's power that gear in the retaining oil groove or chain rotate, centrifugal force, inertial force, oil baffle plays a part to block or encase to liquid, gas, mixture, reaches lubricated and carries purpose.
