Abstract
The invention relates to a crank bush and connecting rod bush of internal combustion engine, wherein the invention is characterized in that: the inner surfaces of crank bush and connecting rod bush that contacted with the crank have lubricant grooves, to reduce the friction contact area, and the groove contains oil to realize better lubricant effect, reduce the friction factor, improve the power of engine and reduce the energy consumption.
Description
Technical field:
The present invention relates to a kind of combustion engine unit, be specifically related to a kind of I. C. engine crankshaft watt, connecting rod bearing shell.
Background technique:
During internal combustion engine, have friction between bent bearing shell, connecting rod bearing shell and bent axle, the size of friction factor directly influences the loss of the power and the energy of internal-combustion engine.Present internal-combustion engine, the surface of contact of bent bearing shell, connecting rod bearing shell and bent axle is slick and sly cambered surface, and rubbing surface is big, and friction factor is relatively large, influences power of IC engine and fuel consumption.
Summary of the invention:
It is little to the purpose of this invention is to provide a kind of and bent axle surface of contact, the bent bearing shell of high lubricating effect, connecting rod bearing shell.
Technological scheme of the present invention is: on I. C. engine crankshaft watt, connecting rod bearing shell and internal surface that bent axle contacts the oil leab groove is set.
The oil leab groove can be provided with one or more.
Technique effect of the present invention is: be provided with the oil leab groove on I. C. engine crankshaft watt and connecting rod bearing shell internal surface, reduced the rubbing contact area, reduced surface friction drag, on the other hand, contained oil in the oil leab groove, made that the lubricant oil in the contact gap is more abundant, lubricated better, so just reduce friction factor, and then improved the power of internal-combustion engine, reduced energy consumption.
Description of drawings:
Fig. 1 is bent bearing shell of the prior art, connecting rod bearing shell structural representation.
Fig. 2 is bent bearing shell of the present invention, connecting rod bearing shell structural representation.
Embodiment:
The present invention is further illustrated in conjunction with the accompanying drawings.
As shown in Figure 1, Fig. 1 is bent bearing shell, the connecting rod bearing shell structural representation of the unlubricated oil duct of internal surface, and its internal surface 1 is level and smooth arc, does not establish oil leab.
As shown in Figure 2, bent bearing shell of the present invention, connecting rod bearing shell, the internal surface 1 that contacts with bent axle is provided with several oil leab grooves 2, so just reduced frictional contact surface, increased oily surface of contact, reduced surface friction drag, simultaneously, along with the work of internal-combustion engine, oil pump with lubricating pump to each lubricated face, bent bearing shell, also exuberant lubricant oil has contained oil in the oil duct groove of connecting rod bearing shell internal surface in the oil duct, makes bent bearing shell, lubricating between connecting rod bearing shell and bent axle is more abundant, reduced bent bearing shell, the friction of connecting rod bearing shell and bent axle, friction factor reduces, thereby has improved the power of internal-combustion engine, has reduced oil consumption.
The present invention is not required to be oil leab and establishes in addition into and out of oil circuit, keeps original confession, fuel-displaced mode to get final product.
The oil leab groove can be provided with one or several as the case may be.
The bent bearing shell of diesel engine, petrol engine, connecting rod bearing shell all are suitable for the solution of the present invention.
Claims (2)
1, a kind of I. C. engine crankshaft watt, connecting rod bearing shell, it is characterized in that: the internal surface that described bent bearing shell, connecting rod bearing shell contact with bent axle is provided with the oil leab groove.
2, I. C. engine crankshaft as claimed in claim 1 watt, connecting rod bearing shell, it is characterized in that: described oil leab groove has one or several.
