Description
Technical field
The utility model relates to motor, is specifically related to a kind of new-typed gasoline engine lubrication system.
Background technique
Motor be a kind of can the machine that can be converted into mechanical energy of other form.Motor comprises body, connecting rod, distribution device, fuel oil supply system, ignition system, cooling system, lubrication system, starting system.Wherein lubrication system refers to and supplies a series of to the general name of grease, oil extraction fat and fixture thereof of oiling agent to lubricant housings.
During engine operation, a lot of driving parts is all under very little gap, do high speed relative movement, as crankshaft main journal and main bearing, crank pin and connecting rod bearing, cam journal and camshaft bearing, piston, piston ring and cylinder wall surface, each kinematic pair of distribution device and driving gear pair etc.Although the working surface of these parts is all through meticulous processing, it is rough for amplifying these surfaces.The clean machine oil that continuously quantity is enough, temperature is suitable when engine operation is transported to the friction surface of whole driving component, and forms oil film between friction surface, realizes liquid friction.Thus reduce surface friction drag, reduce power consumpiton, alleviate component wear, to reach the object improving engine operation reliability and durability.
Existing general dynamic engine lubrication system mostly is splash lubrication or pressure lubrication.Splash lubrication be sealed in the rotational speed of the rotary part in cabinet larger time, lubricant oil is spilt from oil droplet and is atomized into droplet and takes friction pair to and form self oiling, or first focus in oil trap, and then flow into lubricant housings through the oil duct designed.Pressure lubrication is the pressure forcing to increase oiling agent by external force, to setting up the plastic working technique lubricating system of thicker lubricating film between instrument and workpiece contact surface.Above two kinds of lubrication systems have following shortcoming: 1, have bearing, although bearing can play fixing, reduce the effect of load friction, cost is very high, complex process, is difficult to bear high-power, high-revolving working state, and loss is serious; 2, motor still have many places as the place such as bearing, rocking arm lubrication less than, insufficient lubrication, easy motor locking.
Model utility content
The utility model provides a kind of new-typed gasoline engine lubrication system, to reduce motor cost, ensures that motor each moving element lubrication is good, stops locking phenomenon.
This programme is as follows: a kind of new-typed gasoline engine lubrication system, at engine housing, case lid is furnished with oil duct, motor complete machine oil duct arranges Liang Ge branch oil duct after being communicated to filter by oil pump on casing, first branch's oil duct inherent filtration device arrives the abutting end of case lid and bent axle, first branch's oil duct enters crankshaft hole oil duct by abutting end and arrives connecting rod, second branch's oil duct inherent filtration device is drawn, the crankshaft hole port of second branch's oil duct successively on casing, the mating face of casing and cylinder head, and arrive cylinder head cover by cylinder head, second branch's oil duct arrives valve top from cylinder head cover, rocking arm and push rod.
This programme working principle and beneficial effect as follows: the technical program takes the lubricating system of two oil ducts, and oil duct is out divided into two oil ducts from oil pump after filter, and first branch's oil duct arrives the abutting end of case lid and bent axle along case lid, lubricates this abutting end, second branch's oil duct coordinates port along casing through casing and bent axle, lubricate this cooperation port, then second oil duct is communicated to cylinder head from coordinating port along casing, second branch's oil duct arrives the fitting surface of cylinder head and cylinder head cover, second branch's oil duct is from cylinder head cover lubrication valve top, the distribution device such as rocking arm and push rod, adopt this scheme, can fully by bearing and cylinder head cover, cylinder body combines and rocking arm, the places such as push rod are lubricated, all sufficient lubrication can be obtained everywhere with this scheme motor complete machine, because original bearing place also can obtain sufficient lubrication, therefore lubricant oil can reach the effect of the friction factor that bearing reduces equally, bearing can not be adopted, can simplified processing process, reduce motor cost, when second branch's oil duct is near cylinder head, the effect of the temperature reducing cylinder head can be played, ensure that bolt torsion is unattenuated, thus ensure the sealing of cylinder head.
Further, first branch's oil duct balances axis hole by way of case lid, and second branch's oil duct balances axis hole by way of casing, disposable lubrication balance axle, simplified processing process.
Further, the abutting end of case lid and bent axle is provided with case lid oil groove, crankshaft port on casing is provided with casing oil groove, and oil duct enters the crankshaft port on the abutting end of case lid and bent axle and casing by oil groove, abutting end and port can be made to obtain more full and uniform lubrication with this.
Further, mating face is furnished with oil duct, and oil duct enters cylinder head cover inside everywhere from mating face, can increase the lubrication face of the distribution devices such as valve top, rocking arm and push rod.
