Abstract
The utility model belongs to a two O type sealing washer pneumatic cylinder uide bushings of two guidance tapes, including piston rod inside the uide bushing of uide bushing and suit install the dust ring between uide bushing head end internal surface and the piston rod, install first guidance tape, U type circle, this special sealing and the second guidance tape in proper order by head end to end between uide bushing internal surface and the piston rod, install O type circle and the 2nd O type circle on the terminal surface of uide bushing respectively, have simple structure, reasonable in design, safe and reliable, low cost, accurate guidance quality, can prevent effectively that hydraulic oil from leaking and extension pneumatic cylinder life's advantage.
Description
Technical field
The utility model belongs to hydraulic cylinder guide sleeve appurtenances technical field, is specifically related to the two O RunddichtringO hydraulic cylinder guide sleeve of a kind of two guidance tape.
Background technique
Along with the development of engineering, the effect that hydraulic system plays is more and more important, and the effect as the important component part oil hydraulic cylinder of hydraulic system is particularly evident, especially has higher requirement to the accurate guidance quality of oil hydraulic cylinder and sealing; Hydraulic cylinder guide sleeve has the effect supporting and ensure piston rod and cylinder barrel coaxality, in the process that hydraulic cylinder rod stretches out, for the oil sealing of cylinder ports provides a bearing while making oil hydraulic cylinder and cylinder barrel surface contact.Current hydraulic cylinder guide sleeve also exists lower column defects: 1, when oil hydraulic cylinder is longer, and it cannot ensure the accuracy led, and then produces radial force; 2, when hydraulic pressure oil viscosity is higher, due to hydraulic cylinder guide sleeve sealing reason and above-mentioned radial force effect under easily cause hydraulic fluid leak.
Model utility content
The purpose of this utility model is to overcome defect of the prior art and provides simple, reasonable in design, the accurate guidance quality of a kind of structure, effectively can prevent hydraulic fluid leak, extends two guidance tapes pair O RunddichtringO hydraulic cylinder guide sleeve in oil hydraulic cylinder working life.
The purpose of this utility model be achieved in that comprise guide sleeve and be sleeved on guide sleeve inside piston rod, between described guide sleeve head end internal surface and piston rod, dust ring is installed, by head end to end, the first guidance tape, U-shaped circle are installed successively between guide sleeve internal surface and piston rod, this special seal and the second guidance tape; Guide sleeve distal outer surface is separately installed with an O type circle and the 2nd O type circle.
The two O RunddichtringO hydraulic cylinder guide sleeve of the two guidance tapes made according to such scheme, by arranging the first guidance tape and the second guidance tape can prevent guide sleeve and piston rod from producing Metal Contact, when generation radial force can effectively absorb, and the object of accurately guiding can be reached; By arranging the sealing system of this special envelope and U-shaped circle, when the oil film of hydraulic oil is by this special envelope, U-shaped circle can carry out wiping to it, to reduce the leakage of hydraulic oil, simultaneously, guide sleeve outer surface is provided with an O type circle and the 2nd O type circle, when pressure pulsation, more effectively can prevents hydraulic fluid leak; The advantage that there is simple, reasonable in design, safe and reliable, with low cost, the accurate guidance quality of structure, effectively can prevent hydraulic fluid leak and extend oil hydraulic cylinder working life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to there be understanding clearly to technical characteristics of the present utility model, object and effect, now contrast accompanying drawing and embodiment of the present utility model is described, label identical in the various figures represents identical parts.For making simplified form, only schematically show the part relevant to model utility in each figure, they do not represent its practical structures as product.
As shown in Figure 1, the utility model comprises guide sleeve 8 and is sleeved on the piston rod 9 of guide sleeve 8 inside, is provided with dust ring 1 between described guide sleeve 8 head end internal surface and piston rod 9, is provided with the first guidance tape 2, U-shaped circle 3 successively, this specially seals 4 and second guidance tape 7 between guide sleeve 8 internal surface and piston rod 9 by head end to end; Guide sleeve 8 distal outer surface is separately installed with O type circle 5 and a 2nd O type circle 6.
When using the utility model, owing to this hydraulic cylinder guide sleeve being provided with the first guidance tape 2 and the second guidance tape 7, while guarantee accurately guiding, avoiding guide sleeve 8 produce Metal Contact with piston rod 9, also can effectively absorb when producing radial force; In addition, this hydraulic cylinder guide sleeve is provided with this special envelope 4 and U-shaped circle 3, even if the oil film of hydraulic oil is by this special envelope 4 when hydraulic pressure oil viscosity height, U-shaped circle 3 also can fast to its wiping, to reduce the leakage of hydraulic oil; Described guide sleeve 8 distal outer surface is separately installed with O type circle 5 and a 2nd O type circle 6, when pressure pulsation, more effectively can prevents hydraulic fluid leak.
In description of the present utility model, it will be appreciated that, orientation or the position relationship of term " internal surface ", " outer surface ", " inside ", " head end ", " end ", " bottom " etc. instruction are based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " setting ", " installation " etc. should be interpreted broadly, and such as, can be fixedly connected with, connect integratedly, also can be removably connect; Also can be the connection of two element internals; Can be directly be connected, also indirectly can be connected by intermediary, for the ordinary skill in the art, the concrete meaning of above-mentioned term in the utility model can be understood as the case may be.。It is to be noted in this article, " first ", " second " etc. only for differentiation each other, but not represent they significance level and order etc.Detailed description is above only illustrating for feasibility mode of execution of the present utility model; they are also not used to limit protection domain of the present utility model, allly do not depart from equivalent implementations that the utility model skill spirit does, change and transformation all should be included within protection domain of the present utility model.
