Description
Technical field
The utility model belongs to technical field of mechanical, specifically a kind of oil sealing mechanical sealing element.
Background technique
In prior art, oil sealing is in assembling or before using, need the main lip coating butter to oil sealing, the main lip of pre-lubrication is beneficial to oil sealing and axle is installed, and prevents dry friction.Existing mode of smearing butter is, is coated with butter puts the oil to the main lip of oil sealing before assembling with hairbrush.This method Problems existing is: uneven with hairbrush coating, and cause assembling position oil on the high side, assembly just has oil stain once running, and often allowing people think by mistake is occur leakage of oil and cause unnecessary changeing.
Model utility content
The purpose of this utility model solves deficiency of the prior art, provides a kind of oil sealing mechanical sealing element.
The utility model comprises the body being provided with annular groove, is provided with spring in annular groove, has the annular seal lip of protrusion inside body, forms a tapered guide surface between body roof and sealing lip, and the internal diameter of this guide surface reduces gradually along body roof bearing of trend.
Preferably, be provided with ringwise shoe cream room between described annular groove and sealing lip, shoe cream room and annular groove are coaxially arranged and the cavity roof of this shoe cream room upwards extends inwardly to guide surface forms a taper oil outlet one.
Preferably, the quantity of described sealing lip is three and uniform along body length, the cross section indentation of sealing lip and form the groove that cross section is V-shape between adjacent two sealing lips.
Preferably, described inner body wall is pasted with barrier paper, taper oil outlet one seals by this barrier paper.
Preferably, the position corresponding to each sealing lip in annular groove is provided with spring groove, is provided with spring in spring groove.
The utility model, by arranging shoe cream room and taper oil outlet, makes the contact between rotating shaft and sealing lip obtain sufficient lubrication, avoids dry friction; Adopt multiple sealing lip and shaft contacts, increase the sealing effect between oil sealing and rotating shaft; Form the groove in V word between two adjacent sealing lips, be used for storing the butter flowed down from sealing lip or rotating shaft, make form one deck butter film between each sealing lip and rotating shaft and realize selflubricating.In addition, the utility model manufacture cost is not high, and structure is simple, and practical, the utility model is adapted at correlative technology field and applies.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below with reference to accompanying drawings the utility model is described in more detail, which show preferred embodiment of the present utility model, should be appreciated that those skilled in the art can revise the utility model described here and still realize advantageous effects of the present utility model.Therefore, following description is appreciated that extensively knowing for those skilled in the art, and not as to restriction of the present utility model.
In order to clear, whole features of practical embodiments are not described.They in the following description, are not described in detail known function and structure, because can make the utility model chaotic due to unnecessary details.Will be understood that in the exploitation of any practical embodiments, a large amount of implementation detail must be made to realize the specific objective of developer, such as, according to regarding system or the restriction about business, change into another embodiment by an embodiment.In addition, will be understood that this development may be complicated and time-consuming, but be only routine work to those skilled in the art.
For making the purpose of this utility model, feature becomes apparent, and is further described embodiment of the present utility model below in conjunction with accompanying drawing.It should be noted that, accompanying drawing all adopts the form that simplifies very much and all uses non-ratio accurately, only in order to object that is convenient, aid illustration the utility model embodiment lucidly.
As shown in Figure 1, the utility model comprises body 1, barrier paper, spring 3.Wherein, body 1 end face is arranged and is used for placing the annular groove 1a of spring 3, there is inside body 1 outstanding annular seal lip 1b and sealing lip 1b near body 1 top.Form a tapered guide surface 1c between body 1 roof and sealing lip 1b, the internal diameter of this tapered guide surface 1c reduces gradually along body 1 roof bearing of trend.
Specifically, the cross section indentation of sealing lip 1b, and the quantity of sealing lip 1b has three and along the distribution of body 1 uniform length, the contact of oil sealing and rotating shaft 4 is sealed more, improves the oil sealing effect of oil sealing further.
Ringwise shoe cream room 1d is provided with and this shoe cream room 1d and annular groove 1a is coaxially arranged in body 1.The cavity roof of this shoe cream room 1d upwards extends inwardly to guide surface 1c thus forms taper oil outlet one 1e.
When this oil sealing uses, store butter in shoe cream room 1d, when body 1 is squeezed, the butter in shoe cream room 1d to enter in taper oil outlet one 1e and to contact with rotating shaft 4 along guide surface 1c.Adopting taper oil outlet one 1e of inclination, reducing butter when not being squeezed from the possibility of taper oil outlet internal leakage.
Form a groove 1f between adjacent two sealing lip 1b, and this groove 1f is V subtype, is used for storing the butter flowed down from sealing lip 1b or rotating shaft 4, makes form one deck sealing film between each sealing lip 1b and rotating shaft 4 and realize selflubricating.
The position corresponding to each sealing lip 1b in annular groove 1a is provided with spring 3 groove, is provided with and is all provided with spring 3 in each spring 3 groove.Be attached to rotating shaft 4 surface under being respectively sealed in the effect of corresponding spring 3, thus can be formed between each sealing lip 1b for storing butter fat and can preventing butter fat from overflowing from groove 1f, strengthen sealing and the lubrication effect of this oil sealing further.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model embodiment.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from the spirit or scope of the utility model embodiment, can realize in other embodiments.Therefore, the utility model embodiment can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
