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 the moment of torsion power that combustion gas acts on piston top being changed into bent axle, thus to work mechanism output mechanical energy.Connecting rod is generally made up of major body group, piston connecting rod unit, crankshaft-flywheel group, their operating conditions is high temperature, high pressure, high speed and chemical corrosion, so connecting rod insufficient lubrication, the frictional force of relative movement part just becomes large, and mechanical loss strengthens, and engine power will decline.Therefore oil leab design just seems of crucial importance.
Existing crank-connecting rod mechanism for engine oil leab is generally divided into two kinds: a kind of for pressure lubrication be main, splash lubrication is assisted, be characterized in that body is assembled with oil pump, there is elongated oil duct bent axle inside, oil pump, in the oil duct of machine oil press-in bent axle, lubricates stressed and the maximum crank pin of friction and link assembly connecting surface; Another is splash lubrication, and have special oil thrower to splash by machine oil and get up to lubricate the stressed rubbing surface of each motion, wherein a part of machine oil can be splashed in the gap of the 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.As connecting rod small end because inorganic oil is pressed into, the copper sheathing subtracting mould must be increased and ensure wrist pin lubrication.Owing to adding oil pump and copper sheathing, high expensive.
2, splash lubrication uses oil thrower, machine oil is splashed into the stressed friction surface of each motion.But because splash lubrication is ecto-entad, and machine oil easily bubbles, under motor is in high rotating speed high load, friction surface can be caused for shortage of oil, thus affect lubrication effect.
Summary of the invention
Technical problem to be solved by this invention is the high rotating speed petrol engine connecting rod lubrication system providing a kind of lubrication effect good.
Technological scheme of the present invention is as follows: a kind of high rotating speed petrol engine connecting rod lubrication system, piston pin hole (2) is offered the microcephaly of connecting rod (1), the microcephaly of connecting rod (1) is connected with piston (21) by the wrist pin (20) be located in piston pin hole (2), piston (21) is arranged in the cylinder liner on crankcase (22), major part and the connecting rod cap (3) of connecting rod (1) connect, fixed by first connecting rod bolt (4) and second connecting rod bolt (4 '), the second arc groove on the first arc groove on connecting rod (1) major part and connecting rod cap (3) surrounds and forms crank pin hole (5), top bearing shell (6) and lower bearing (7) are housed in this crank pin hole (5), the middle part in crank pin (23) encircled by top bearing shell (6) and bearing shell (7), the two ends, left and right of crank pin (23) are connected with left crank (24) and right crank (25) respectively, left crank (24) is all supported by bearing and crankcase (22) mutually with right crank (25), one end of described connecting rod cap (3) bottom extends obliquely, oil clot (8) is got rid of in formation, the inwall of the first arc groove of described connecting rod (1) major part has upper oil trap (9), on this, oil trap (9) is looped around the outside of top bearing shell (6), and top bearing shell (6) has the first oil inlet hole (10), the inner and outer surface of the first oil inlet hole (10) through top bearing shell (6), the inwall of the second arc groove of described connecting rod cap (3) has lower oil trap (11), this lower oil trap (11) is looped around the outside of lower bearing (7), and on lower bearing (7), have the second oil inlet hole (12), the inner and outer surface of this second oil inlet hole (12) through lower bearing (7), described lower oil trap (11) and upper oil trap (9) connect, the groove of a composition 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 on connnecting rod big end and connecting rod cap, and oil inlet hole offered by bearing shell, and sets up oil leab getting rid of in oil clot.When motor is in rotary work state, gets rid of oil clot and touch the machine oil in crankcase and make it splash.The oil-feed tank got rid of on oil clot scoops up machine oil and stores, and machine oil under the influence of centrifugal force, enters lower oil trap by the oil duct of connecting rod cap.Lower oil trap place machine oil a part by the second oil inlet hole enter lower bearing internal surface lubrication crankpin, another part enters the upper oil trap of connnecting rod big end under the influence of centrifugal force.The machine oil at upper oil trap place enters top bearing shell internal surface lubrication crankpin by the first oil inlet hole.Meanwhile, machine oil splashes by getting rid of oil clot, and the miscellaneous part in a part of lubricating engine crankcase, a part is splashed into connecting rod small end, lube pistons pin.
As can be seen here, the present invention is not when changing petrol engine performance and lubricating system, unidirectional lubrication oil-feed is changed into Bidirectional lubricating oil-feed, thoroughly solve the link assembly lubrication problem of rev-happy engine, not only structure is simple, make easily, and can guarantee that each friction surface fuel feeding of link assembly is sufficient, lubrication effect is not only good but also reliable.
