Description
Technical field
The utility model belongs to engine component technical field, particularly relates to a kind of engine link that effectively can improve engine operating efficiency.
Background technique
In today that the public improves day by day to environmental improvement demand, internal-combustion engine is required again larger Power output simultaneously, and more low energy consumption is the requirement of lower carbon emission.At present for reaching this object, way basic in diesel engine arts improves constantly the combustion efficiency of fuel and constantly reduces the frictional work of friction pair.Meanwhile, also to movement parts more lightweight propose requirement.The lightweight of movement parts is conducive to allowing the energy ezpenditure consuming or rotary motion reciprocal in movement parts constantly be declined.But traditional lightweight of movement parts is simultaneously often along with the reduction of mechanical strength, to the risk of Security, generally for and meet security requirement, need to reduce fuel combustion pressure of explosion simultaneously, and this can cause the loss of fuel energy to improve, weaken the amplitude that the original energy consumption of lightweight reduces.Wherein, engine link mechanism is one of kernel component of motor, the active force between piston and bent axle is transmitted in the effect of connecting rod, connecting rod be two ends respectively with initiatively and driven member is hinged moves and the rod member of power to transmit, engine link is used to piston in connecting engine and bent axle, connecting rod is made up of connecting rod small end, connecting rod shank and connnecting rod big end, and its function is that the power of being born by piston passes to bent axle, and changes the to-and-fro motion of piston the rotary motion of bent axle into.Connecting rod small end is connected with wrist pin, reciprocating together with piston; Connnecting rod big end is connected with crank pin, rotates together with bent axle, and therefore when engine operation, complicated plane motion done by connecting rod.Connecting rod mainly bears compression, stretch and the stress alternation such as bending, requires that connecting rod must have enough fatigue strength and structural rigidity.Meanwhile, connecting rod is on the basis of proof strength and rigidity, and weight reduction of should trying one's best, to reduce the vibration of motor.
Model utility content
The utility model overcomes deficiency of the prior art, and provide a kind of engine connecting rod structure, it is simple and reasonable, has enough strength and stiffness, can bear compression, stretch and the stress alternation such as bending, and lightweight.
The utility model solves the technological scheme that its technical problem adopts:
A kind of engine connecting rod structure, comprise connecting rod small end, connecting rod shank, connnecting rod big end, connecting rod cap, connecting rob bushing and connecting rod bearing shell, the two ends of connecting rod shank connect connecting rod small end and connnecting rod big end respectively, the left and right sides of connecting rod cap is provided with through hole, on connnecting rod big end, the lead to the hole site place of respective link lid is provided with corresponding tapped hole, connecting rod cap is bolted to connection on connnecting rod big end, connecting rob bushing presses in the piston mounting holes of connecting rod small end, it is characterized in that: the both ends of the surface of connecting rod small end adopt angular cut, the nose width of connecting rod small end is less than rear end width, the junction surface of connnecting rod big end and connecting rod cap is provided with angular cut, the junction surface of cutting sth. askew of connnecting rod big end and connecting rod cap is provided with the bearing shell mounting groove of installing connecting rods watt, connecting rod bearing shell is fixedly mounted in the bearing shell mounting groove on the junction surface of connnecting rod big end and connecting rod cap, connecting rod bearing shell is axially locked, connecting rod small end is 128mm to the centre distance of connnecting rod big end, the exradius of connecting rod small end is 19.5mm, the diameter of bore of connecting rod small end is 29mm, the diameter of bore of connnecting rod big end is 48mm, the width of connnecting rod big end is 28.2mm, it is 0.22mm ~ 0.38mm that connnecting rod big end and rod journal open grade gap.
Further, the both ends of the surface of connnecting rod big end and connecting rod cap are provided with drain pan.
Further, the nose width of connecting rod small end is 20mm, and the rear end width of connecting rod small end is 22.5mm.
Because the both ends of the surface of connecting rod small end of the present utility model adopt angular cut, the nose width of connecting rod small end is made to be less than rear end width, up-narrow and down-wide form facilitates the design of piston seat, ensure that the intensity of connecting rod, decrease connecting rod weight, the vibration of effective minimizing motor, it is 0.22mm ~ 0.38mm that the axle journal of connnecting rod big end and connecting rod shank opens grade gap, the both ends of the surface of connnecting rod big end and connecting rod cap are provided with drain pan, thus relatively reduce cylinder sleeve direction get rid of oil mass, be conducive to controller oil consumption, the oil film pressure improved between connecting rod bearing shell and rod journal is played a key effect.
The utility model is simple and reasonable, easy to use, while guarantee connecting rod strength and hardness, decreases connecting rod gross weight, ensures the lightweight of movement parts, thus is conducive to allowing the energy ezpenditure consuming or rotary motion reciprocal in movement parts constantly be declined.
