Description
Technical field
The invention belongs to technical field of engines, specifically, particularly a kind of lubrication system of high rotating speed petrol engine connecting rod.
Background technique
Connecting rod is the important constituent element of motor, and function is that combustion gas is acted on the moment of torsion that power on the piston top changes bent axle into, thereby to the work mechanism output mechanical energy.Connecting rod generally is made of main body group, piston rod group, crankshaft-flywheel group, their operating conditions is high temperature, high pressure, high speed and chemical corrosion, so connecting rod insufficient lubrication, it is large that the frictional force of relative movement part just becomes, and mechanical loss strengthens, and engine power will descend.So the oil leab design just seems of crucial importance.
Existing crank-connecting rod mechanism for engine oil leab generally is divided into two kinds: a kind of for pressure lubrication be main, splash lubrication is auxiliary, be characterized in that body is assembled with oil pump, there is elongated oil duct bent axle inside, oil pump is pressed into machine oil in the oil duct of bent axle, lubricated stressed and the crank pin of friction maximum and the connecting surface of link assembly; Another is splash lubrication, special-purpose oil thrower is arranged by the machine oil lubricated stressed rubbing surface that respectively moves that splashes, and wherein a part of machine oil can be splashed in the slit of connecting surface of crank pin and link assembly, makes it reach lubrication effect.The deficiency that existing two kinds of oil leabs exist is:
1, pressure lubrication mode mechanism design is complicated, and processing technology is high, and cost is higher., must increase the copper sheathing that subtracts mould and guarantee that wrist pin is lubricated because inorganic oil is pressed into such as connecting rod small end.Owing to increased oil pump and copper sheathing, high expensive.
2, splash lubrication uses oil thrower, and machine oil is splashed into the stressed friction surface that respectively moves.But because splash lubrication is ecto-entad, and machine oil bubbles easily, is under the high rotating speed high load at motor, can cause friction surface for shortage of oil, thereby affect lubrication effect.
Summary of the invention
The high rotating speed petrol engine connecting rod lubrication system that provides a kind of lubrication effect good is provided technical problem to be solved by this invention.
Technological scheme of the present invention is as follows: a kind of high rotating speed petrol engine connecting rod lubrication system, microcephaly at connecting rod (1) offers piston pin hole (2), the microcephaly of connecting rod (1) is connected with piston (21) by the wrist pin (20) that is located in the piston pin hole (2), piston (21) is arranged in the cylinder liner on the crankcase (22), the major part of connecting rod (1) and connecting rod cap (3) connect, fixing by first connecting rod bolt (4) and second connecting rod bolt (4 '), the first arc groove on connecting rod (1) major part and the second arc groove on the connecting rod cap (3) surround and form crank pin hole (5), top bearing shell (6) and lower bearing (7) are housed in this crank pin hole (5), top bearing shell (6) and bearing shell (7) are encircled the middle part in crank pin (23), the two ends, the left and right sides of crank pin (23) respectively with left crank (24) be connected crank (25) and be connected, left crank (24) all supports by bearing and crankcase (22) mutually with right crank (25), the oblique downward-extension of one end of described connecting rod cap (3) bottom, oil clot (8) is got rid of in formation, inwall at the first arc groove of described connecting rod (1) major part has upper oil trap (9), upward oil trap (9) is looped around the outside of top bearing shell (6), and have the first oil inlet hole (10) on the top bearing shell (6), the first oil inlet hole (10) connects the inner and outer surface of top bearing shell (6); Inwall at the second arc groove of described connecting rod cap (3) has lower oil trap (11), this time oil trap (11) is looped around the outside of lower bearing (7), and having the second oil inlet hole (12) at lower bearing (7), this second oil inlet hole (12) connects the inner and outer surface of lower bearing (7); Described lower oil trap (11) and upper oil trap (9) connect, and form the groove of a ring, and lower oil trap (11) by oil duct (13) with get rid of the oil-feed tank (14) that oil clot (8) end face offers and communicate.
The present invention increases oil trap at connnecting rod big end and connecting rod cap, offers oil inlet hole at bearing shell, and sets up oil leab in getting rid of oil clot.When motor is in the rotary work state, gets rid of oil clot and touch the machine oil in the crankcase and it is splashed.Get rid of oil-feed tank on the oil clot and scoop up machine oil and storage, machine oil is under the effect of centrifugal force, and the oil duct by connecting rod cap enters lower oil trap.The machine oil part at lower oil trap place is by the second oil inlet hole lubricated crankpin of lower bearing internal surface of entering, and another part enters the upper oil trap of connnecting rod big end under the effect of centrifugal force.The machine oil at upper oil trap place enters the lubricated crankpin of top bearing shell internal surface by the first oil inlet hole.Simultaneously, machine oil splashes by getting rid of oil clot, the miscellaneous part in a part of lubricating engine crankcase, and a part is splashed into connecting rod small end, the lube pistons pin.
This shows, the present invention is in the situation that does not change petrol engine performance and lubricating system, unidirectional lubricated oil-feed is changed into the Bidirectional lubricating oil-feed, thoroughly solved the link assembly lubrication problem of rev-happy engine, not only simple in structure, make easily, and can guarantee that each friction surface fuel feeding of link assembly is sufficient, lubrication effect not only well but also reliable.
