Description
Technical field
The utility model belongs to mechanical part technical field, relates to a kind of piston, particularly relates to a kind of selflubricating cylinder piston head.
Background technique
Piston in cylinder is made up of piston head and piston rod, and piston head linearly moves reciprocatingly in cylinder, is very easy to wearing and tearing.Therefore the quality of piston head directly determines the working life of cylinder.Due to long-term friction, the lubrication effect between piston head and cylinder inner wall worse and worse, can cause piston head to be stuck in cylinder, makes cylinder cisco unity malfunction.
In order to overcome the deficiencies in the prior art, people are through constantly exploring, propose various solution, as Chinese patent literature discloses a kind of piston head [patent No.: CN101761412A] of Wear, this piston head is provided with the pin shaft hole laterally running through piston head, the top of pin shaft hole is provided with hides to piston ring groove, it is piston skirt below pin shaft hole, above described pin shaft hole and be provided with the step of a radial protrusion, the diameter at step place and piston skirt equal diameters under mouth together between piston ring groove.
Such scheme reaches equalizing piston by piston ring, and the object of adjusting play, during work, upper piston area does not contact with cylinder inner wall, even if operating mode is bad, after piston receives certain wearing and tearing, upper piston area still can keep having certain distance between cylinder inner wall, can avoid scuffing of cylinder bore, eccentric wear.But the program does not have from the effect of moistening, and piston is is still easily worn and torn, and during as serious wear, then cannot work; In addition, the program is the piston for internal-combustion engine, cannot be general with the piston of cylinder.
Model utility content
The purpose of this utility model is for the problems referred to above, provides a kind of nonabradable selflubricating cylinder piston head.
For achieving the above object, the utility model have employed following technical proposal: a kind of selflubricating cylinder piston head, comprise piston head body, this piston head body is cylindric and on outer wall, is embedded with seal ring mechanism, described piston head body interior has one for placing the shoe cream room of lubricant oil, the some oil guide pipes of this shoe cream room connect seal ring mechanism, described oil guide pipe distributes uniformly along the spaced radial of piston head body, and the direction of aperture from shoe cream room toward seal ring mechanism of every root oil guide pipe reduces gradually.
In above-mentioned selflubricating cylinder piston head, connect with connecting tube between every two adjacent oil guide pipes.
In above-mentioned selflubricating cylinder piston head, shape, the size of every root connecting tube are identical.
In above-mentioned selflubricating cylinder piston head, described connecting tube is arc pipe and each oil guide pipe is interconnected to form the pipeline of ring.
In above-mentioned selflubricating cylinder piston head, described piston head body is provided with a pouring orifice, and this pouring orifice oil filling pipeline connects shoe cream room, and the dismountable sealing of pouring orifice sealing nut.
Compared with prior art, the utility model has the advantage of: by shoe cream room, continual fuel feeding is carried out to seal ring mechanism, make seal ring mechanism and piston head body and cylinder inner wall contact lubricated, flexibly mobile, thus avoid the wearing and tearing of piston head body and seal ring mechanism, extend the working life of piston head, also make cylinder operation more stable.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model provides;
Fig. 2 is the A-A sectional view of Fig. 1.
In figure: piston head body 10, seal ring mechanism 20, shoe cream room 30, oil guide pipe 40, connecting tube 50, pouring orifice 60, oil filling pipeline 70, sealing nut 80.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1-2, a kind of selflubricating cylinder piston head, comprise piston head body 10, this piston head body 10 is cylindric and on outer wall, is embedded with seal ring mechanism 20, described piston head body 10 inside has one for placing the shoe cream room 30 of lubricant oil, and the some oil guide pipes 40 of this shoe cream room 30 connect seal ring mechanism 20, and described oil guide pipe 40 distributes uniformly along the spaced radial of piston head body, also can be understood as, oil guide pipe 40 radially arranges.Because piston head body 10 needs repeatedly to contact with cylinder inner wall, therefore when contact is not lubricated, the wearing and tearing of meeting accelerating piston head body 10 and seal ring mechanism 20, when serious wear, piston head body 10 can be stuck in cylinder inner wall, causes cylinder normally to work, and the lubricant oil in shoe cream room 30 can continue to be supplied to seal ring mechanism 20, produce lubrication by seal ring mechanism 20 pairs of cylinder inner walls, reduce the wearing and tearing of piston head body 10 and seal ring mechanism 20, extend the working life of cylinder.
Preferably, the aperture of oil guide pipe 40 biggest place is between 0.5-1.0mm, and the aperture at minimum place is between 0.1-0.5mm.
Piston head body 10 is provided with a pouring orifice 60, and this pouring orifice 60 oil filling pipeline 70 connects shoe cream room 30, and the pouring orifice 60 dismountable sealing of sealing nut 80, take sealing nut 80 apart, lubricant oil can be added from pouring orifice 60 toward shoe cream room 30.
As preferred scheme, and the direction of aperture from shoe cream room 30 toward seal ring mechanism 20 of every root oil guide pipe 40 reduces gradually, forms the effect of capillary penetration.
Connect with connecting tube 50 between every two adjacent oil guide pipes 40, this connecting tube 50 makes oil guide pipe 40 mutual conduction, makes the oil mass in every root oil guide pipe 40 substantially equal, seal ring mechanism 20 is played to the effect of evenly lubrication.Preferably, the shape of every root connecting tube 50, size are identical.Connecting tube 50 is arc pipe and each oil guide pipe 40 is interconnected to form the pipeline of ring.Obviously, connecting tube 50 also can be set to multiple, thus forms the pipeline of multiple ring.
Working principle of the present utility model is: the principle adopting capillary penetration, lubricant oil is added to the continual enforcement of seal ring mechanism 20, thus keep the lubricity of seal ring mechanism 20, piston head body and cylinder inner wall is made to move flexibly, the phenomenon of " card " can not be produced, thus whole cylinder operation is stablized, also improve the working life of cylinder.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
Although more employ the terms such as piston head body 10, seal ring mechanism 20, shoe cream room 30, oil guide pipe 40, connecting tube 50, pouring orifice 60, oil filling pipeline 70, sealing nut 80 herein, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present utility model more easily; The restriction that they are construed to any one additional is all contrary with the utility model spirit.
