Abstract
The utility model discloses a kind of connection rod of automobile engine bearing shell, comprise semicircular bearing shell body, the described bearing shell body comprises metal watt back of the body and alloy-layer are formed, be symmetrically arranged with oil groove respectively at the Wa Kou two ends of described bearing shell inner body wall, and at the inside edge place at Wa Kou two ends, chamfering be set respectively.The utility model can reduce bearing shell and pull risk, improves lubrication effect, improves working life.
Description
Technical field
The utility model relates to a kind of engine component, is specially a kind of connection rod of automobile engine bearing shell.
Background technique
Connecting rod bearing shell is one of important spare part of motor car engine, and its operating conditions is severe: the reciprocal inertia force bearing gas pressure and piston connecting rod unit on the one hand, bears the friction and wear of the solid particle in lubricant oil on the other hand.The failure mode of bearing shell has multiple, and wherein common is pulling of solid impurity.Owing to inevitably there is solid impurity in engine lubricating oil or in component oil duct, solid impurity in lubricant oil destroys the formation of oil film when entering the sliding friction surface of bearing shell and crankshaft journal, cause insufficient lubrication, bearing shell is pulled, alloy-layer comes off so that Bearing Failure.Along with supercharging, the utilization on the engine of straight spray new technology, engine flare pressure improves constantly, and to bearing capacity, the wear resistance of connecting rod bearing shell, shoulders occlusion property etc. and requires higher.Be illustrated in figure 1 existing connecting rod bearing shell, its semicircular bearing shell body 1 is carried on the back by metal tile and alloy-layer is formed, and alloy-layer is easily pulled by impurity, there is insufficient lubrication risk.
Summary of the invention
The purpose of this utility model is to provide a kind of connection rod of automobile engine bearing shell, pulls risk, improve lubrication effect to reduce bearing shell, improves working life.
Connection rod of automobile engine bearing shell described in the utility model, comprise semicircular bearing shell body, the described bearing shell body comprises metal watt back of the body and alloy-layer are formed, and be symmetrically arranged with oil groove respectively, and arrange chamfering respectively at the inside edge place at Wa Kou two ends at the Wa Kou two ends of described bearing shell inner body wall.
Preferably, described oil groove is curve bath, and its radius of arc is 10 ~ 15mm, and oil groove axial width is 3 ~ 4mm, and radial height is 5 ~ 6mm, and the oil groove degree of depth is 0.5 ~ 0.8mm.
Preferred described chamfering angle size is C0.3 ~ C0.5.
Motor operationally, solid impurity and lubricant oil enter connecting rod bearing shell working surface described in the utility model along crankshaft oil gallery, impurity docks formed cell body in crankshaft operation effect lower slider to two bearing oil-grooves at the pressure of lubricant oil, impurity is contained in cell body or along the passage that two chamferings are formed and discharges outside bearing shell, thus reduces and pull bearing bush antifriction alloy-layer risk.Simultaneously oil groove has oil storage function, can improve the boundary lubrication of bearing shell at engine oil pressure during low or cold start-up.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, and following examples, only for explaining the utility model, do not form the restriction to the utility model protection domain.
Embodiment one:
Connection rod of automobile engine bearing shell as shown in figs 2-4, comprise semicircular bearing shell body 1, described bearing shell body 1 is made up of the metal tile back of the body 2 and alloy-layer 3, be symmetrically arranged with oil groove 4 respectively at the Wa Kou two ends of described bearing shell inner body wall, and chamfering 5 is set respectively at the inside edge place at Wa Kou two ends.Described oil groove 4 is curve bath, and its radius of arc R is 10mm, and oil groove axial width B is 3mm, radial height H is 5mm, and oil groove depth B 1 is 0.5mm, and described chamfering 5 size is C0.3.
See Fig. 5, two connecting rod bearing shells are when assembling, a watt mouth for two bearing shell bodies 1 connects, the oil groove of the correspondence on two bearing shell bodies is made to be combined into the cell body 6 of an accommodating lubricant oil and solid impurity, the chamfering at described two bearing shell bodies watt mouth place forms the channel of chip removal 7 be communicated with described cell body, thus is discharged by the solid impurity in cell body 6.
Embodiment two:
Connection rod of automobile engine bearing shell described in the present embodiment is identical with the technical characteristics major part of connecting rod bearing shell described in embodiment one, difference is only, in the present embodiment, the radius of arc of oil groove is 15mm, oil groove axial width is 4mm, radial height is 6mm, the oil groove degree of depth is 0.8mm, and described chamfering angle size is C0.5.
