Description

A kind of connecting rod small-end bearing component
Technical field
The utility model is related to compressor lubrication technical field, more particularly to a kind of connecting rod small-end bearing component.
Background technology
With the development of compressor industry, how to ensure the lubrication of connecting rod small-end bearing and reduce weight of the abrasion by each side Depending on traditional copper sheathing lubrication system uses old-fashioned straight groove structure, and poor fluidity of the lubricating oil in groove is easily caused oil temperature liter Height, destroys lubricating oil film, causes copper sheathing to wear and tear afterwards, with certain limitation, wear extent is larger, especially only by unilateral power Situation, its lubricant effect is it cannot be guaranteed that short with service life.
It can be seen that being current to be badly in need of solving there is provided a kind of connecting rod small-end bearing component for being capable of service life length and high lubricating effect One of problem.
Utility model content
The utility model is completed to solve of the prior art not enough, and the purpose of this utility model is to provide one Connecting rod small-end bearing component is planted, the reliability of connecting rod small-end bearing lubrication is ensure that, wear extent is reduced, and extend its service life.
A kind of connecting rod small-end bearing component of the present utility model, including copper sheathing body (1), the connecting rod small-end bearing component are provided with edge At least one helicla flute (2) of copper sheathing body (1) the inner surface circumferencial direction extension, the helicla flute (2) is tilting Helicla flute (2).
A kind of connecting rod small-end bearing component of the present utility model can also be:
Copper sheathing body (1) outer surface is provided with the circular groove extended along copper sheathing body (1) outer surface circumferencial direction (3)。
The circular groove is provided with least one circular hole (4).
Every helicla flute (2) is disposed in an evenly spaced relation on copper sheathing body (1) inner surface.
The adjacent helicla flute (2) be arranged in parallel.
The copper sheathing body (1) is shaped as cylinder.
A kind of connecting rod small-end bearing component of the present utility model, including copper sheathing body (1), the connecting rod small-end bearing component are provided with edge At least one helicla flute (2) of copper sheathing body (1) the inner surface circumferencial direction extension, the helicla flute (2) is tilting Helicla flute (2).So, copper sheathing body (1) inner frictional surface is set to helicla flute (2) structure of tilting.Using spiral Groove (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, carry The high reliability of lubrication, reduces abrasion;The presence of lubricating oil film can be ensured to greatest extent, the reliability of lubrication is improved, Copper sheathing body (1) abrasion is reduced, and extends its service life;On the other hand lubricating oil is extended using helicla flute (2) structure to exist The time of outflow in helicla flute (2), make lubricating oil along helicla flute (2) lubrication, outflow, it is ensured that the lubrication of copper sheathing body (1) Property, while ensureing certain mobility, high oil temperature is prevented, lubricating oil film is destroyed.A kind of connecting rod small-end bearing group of the present utility model Part, ensure that the reliability of connecting rod small-end bearing lubrication, reduce wear extent, and extend its service life.

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 It can also be:The outer surface of copper sheathing body 1 is provided with the circular groove along the outer surface circumferencial direction extension of copper sheathing body 1.This Sample, the inner structure form of copper sheathing body 1 uses the structure of helicla flute 2;The disposed outside circular groove 3 of copper sheathing body 1, outside circular groove 3 Arrangement, can effectively ensure that the relative flow of lubricating oil, it is to avoid localized hyperthermia, aggravates friction, so as to burn copper Cover body 1.Further preferred scheme is:The circular groove 3 is provided with least one circular hole 4.So, outside copper sheathing body 1 Circular hole 4 is arranged on circular groove, the further relative flow for ensureing lubricating oil, it is to avoid localized hyperthermia aggravates friction, so as to burn Ruin copper sheathing body 1.It can also be:Every helicla flute 2 is disposed in an evenly spaced relation on the inner surface of copper sheathing body 1.So, Every helicla flute 2 is uniformly arranged on the inner surface of copper sheathing body 1, its technique is simple, and ensure that lubricating oil along spiral Groove 2 lubricates, flowed out, it is ensured that the lubricity of copper sheathing body 1, while ensureing certain mobility.It can also be:The adjacent spiral shell Spin slot 2 be arranged in parallel.It can also be:The copper sheathing body 1 is shaped as cylinder.So, copper sheathing body 1 is set to cylinder Body, can meet its assembling and convenient dismounting.Can also be the other shapes such as cylinder, as long as actual production demand can be met .
