Embodiment
Fig. 1 below in conjunction with the accompanying drawings to Fig. 4 is described in further detail to a kind of connecting rod small-end bearing component of the present utility model.
A kind of connecting rod small-end bearing component of the present utility model, refer to Fig. 1-4, including copper sheathing body 1, the connecting rod small-end bearing group
Part is provided with least one helicla flute 2 extended along the inner surface circumferencial direction of copper sheathing body 1, and the helicla flute 2 is inclination
The helicla flute 2 of formula.So, the inner frictional surface of copper sheathing body 1 is set to the structure of helicla flute 2 of tilting.Using helicla flute 2
Structure, on the one hand its processing is simple, and it is not straight-through with outer, can ensure the presence of lubricating oil film to greatest extent, improve
The reliability of lubrication, reduces abrasion；The presence of lubricating oil film can be ensured to greatest extent, the reliability of lubrication is improved, reduced
Copper sheathing body 1 weares and teares, and extends its service life；On the other hand lubricating oil is extended in helicla flute 2 using the structure of helicla flute 2
The time of outflow, lubricating oil is set to lubricate, flow out along helicla flute 2, it is ensured that the lubricity of copper sheathing body 1, while ensureing certain
Mobility, prevent high oil temperature, destroy lubricating oil film.A kind of connecting rod small-end bearing component of the present utility model, ensure that connecting rod
The reliability of copper bush lubrication, reduces wear extent, and extend its service life.
A kind of connecting rod small-end bearing component of the present utility model, refer to Fig. 1-4, on the basis of previously described technical scheme
