Description
Technical field
The utility model relates to air compressor field more particularly to a kind of oil-free air compressor connecting rods with stuffing hole.
Background technique
The lubrication of piston rod microcephaly's needle bearing of existing oil-free air compressor is usually to rely on small end of connecting rod living
Grease lubrication in plug pin.However, because the pin hole capacity in piston pin is limited, with the long-time service of machine, in piston pin
Lubricating grease will slowly be consumed；When the lubricating grease in piston pin, which is consumed, to be finished, the key component connecting rod of air compressor machine and work
It is dangerous that plug will also face severe Fast Wearing.
So far, also it is no lack of that there are some piston rods with associated lubrication structure in the market, however its structure is equal
It is relative complex, and inconvenience is processed, it is unfavorable for industrialized development.
Accordingly, it is badly in need of a kind of simple structure and convenient processing at present, and there is long-term, effectively lubricating effect oil-free pneumatics
Machine connecting rod.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of simple structure and convenient processings, and have it is long-term,
The oil-free air compressor connecting rod with stuffing hole of effectively lubricating effect.
The utility model solves above-mentioned technical problem using following technical scheme：
A kind of oil-free air compressor connecting rod with stuffing hole including shaft and is respectively arranged at the big end, small at shaft both ends
End, big end are provided with big end axis hole, and small end is provided with small end axis hole；The shaft offers an opening direction along its length
The stuffing hole in wrist-pin end of connecting rod direction, which runs through small end bottom end, and extends upwardly to through small end top to be shaped to one
Aperture.
One of preferred embodiment as the utility model, the stuffing hole is equal with the aperture of small end top aperture, axis
It coincides.
The hole depth of one of preferred embodiment as the utility model, the stuffing hole is slightly less than the length of shaft.
One of preferred embodiment as the utility model, the aperture in the stuffing hole are specially 8-10mm, hole depth 70-
75mm。
One of preferred embodiment as the utility model, the small end axis hole match with the needle bearing for being cased with piston pin
It closes.
The utility model compared with prior art the advantages of be：
(1) structure is simple, easy to use；
It (2) is carrier using connecting rod shank, in the stuffing hole for opening up an opposite elongate on connecting rod shank, which can be straight
It connects for loading lubricating grease；Compared to traditional various tank filler sleeves for being set to wrist-pin end of connecting rod, company is utilized in the stuffing hole of the application
The length advantage of club body itself greatly increases the saturation of the lubricating grease inside stuffing hole, to substantially increase pneumatics
The service life of machine；
(3) only need to be in the downward aperture in small end top of conventional linkage, and keep along shaft straight down to processing an appearance
Receive the elongated hole of lubricating grease, entire machining process is simple and convenient to operate.

Specific embodiment
It elaborates below to the embodiments of the present invention, the present embodiment before being with technical solutions of the utility model
It puts and is implemented, the detailed implementation method and specific operation process are given, but the protection scope of the utility model is unlimited
In following embodiments.
Embodiment 1
As shown in Figs. 1-5, a kind of oil-free air compressor connecting rod with stuffing hole of the present embodiment, structure is simple, easy to use,
Including shaft 1 and it is respectively arranged at the big end 2 at 1 both ends of shaft, small end 3, big end 2 is provided with big end axis hole 21, and small end 3 is arranged
There is small end axis hole 31.Wherein, the small end axis hole 31 of small end 3 is matched with the needle bearing (not indicating in figure) for being cased with piston pin.
Connecting rod shank 1 offers an opening towards the stuffing hole 4 in 3 direction of wrist-pin end of connecting rod, 4 hole of stuffing hole along its length
Diameter 8-10mm, hole depth 70-75mm (length that the hole depth in stuffing hole 4 is slightly less than shaft 1) play lubrication for loading lubricating grease
Effect；The stuffing hole 4 is specifically set at the center of shaft 1, and 3 bottom end of small end is run through in stuffing hole 4, and extends upwardly to through small
3 tops are held to be shaped to an aperture 32；Wherein, stuffing hole 4 is equal with the aperture of aperture 32 on 3 top of small end, and axis is also mutually overlapped
It closes.
Process application method：
Since 3 top of small end of connecting rod, an elongated hole is processed as stuffing hole 4 along 1 direction of shaft；It, will when assembly
Lubricating grease is filled up in stuffing hole 4；When assembling needle bearing, by the stuffing hole 4 on the aperture face connecting rod shank 1 above bearing.
Advantage of this embodiment is that：
(1) structure is simple, easy to use；
It (2) is carrier using connecting rod shank 1, in the stuffing hole 4 for opening up an opposite elongate on connecting rod shank 1, the stuffing hole 4
It can be directly used for loading lubricating grease；Compared to traditional various tank filler sleeves for being set to wrist-pin end of connecting rod 3,4 benefit of stuffing hole of the application
With the length advantage of connecting rod shank 1 itself, greatly increase the saturation of the lubricating grease inside stuffing hole 4, to mention significantly
The high service life of air compressor machine；
(3) only need to be in the downward aperture in 3 top of small end of conventional linkage, and keep along shaft 1 straight down to processing one
The step of elongated hole of receiving lubricating grease, entire technical process, is simple and convenient to operate.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
