Abstract

The present invention relates to oil seal technique field, it is specifically related to wide lip power type rubber oil sea, including oil sealing rubber and metallic framework, oil sealing rubber and metallic framework disposably overall sulfidization molding, described oil sealing rubber and a length of 4 7mm of lip of shaft contacts, lip and shaft contacts face are molded with a helical form return wire.The invention have the benefit that the wide bead structure of employing, improve the lip fit-state to axial plane further, and the radial direction making lip grant axial plane seizes power and is more evenly distributed, softer, be conducive to promoting lip and the service life of axle;Seizing at lip and arrange helical form return wire on face, make " pumping power " usefulness of oil sealing embody and become apparent from, auxiliary seal effect further enhances, and seepage probability is greatly lowered;Elastomeric material is used to avoid the unstability of politef.

Description

Wide lip power type rubber oil sea
Technical field:
The present invention relates to oil seal technique field, be specifically related to wide lip power type rubber oil sea.
Background technology:
At present, automobile shafts oil sealing typically uses band spring narrow lip type rubber oil sea (shown in Fig. 1) and politef width Lip oil sealing (shown in Fig. 2).
Band spring narrow lip type rubber oil sea seizes face narrower (0.2-0.4mm) due to lip, in addition the seizing of its lip Power is again to be realized by the coil spring being installed on lip and maintained, therefore, suffered by the lip being fitted on axial plane Radial force Relatively centralized, and strength is the most uneven relatively greatly, and when machine at high speeds runs, lip easily produces high temperature and even produces Raw abrasion, the bright phenomenon of burning, and then make the sealing function of oil sealing completely lose.It addition, this structure oil sealing setting on lip Return wire is a plurality of line segment shape, is unfavorable for the generation of oil sealing " pumping power ", and the power-assisted therefore produced during oil sealing work is close Envelope effect is poor, pushes away oil and heat dissipation is the most weak.
Although the wide lip (face of seizing reaches 3-5mm) of politef width lip oil sealing employing and wall scroll helical form return wire, and relatively Solve well band spring narrow lip type rubber oil sea at the excessive skewness of the power that seizes, " pumping power " is more weak, push away oil and heat dissipation The most weak problem, oil sealing integral sealing reliability also been significantly enhanced, but due to this high molecular polymerization of politef Thing is when temperature is less than 10 DEG C, and its texture can be the most hardening, is unfavorable for that oil sealing seizes lip trackability and seizes the good of state Maintaining, impact the most also can to oil sealing installation process, therefore polytetrafluoroethyloil oil seals is also deposited in the selection of main lip material At obvious flaw.
Summary of the invention:
The technical problem to be solved is to overcome existing technological deficiency, it is provided that a kind of good airproof performance, use The wide lip power type rubber oil sea of life-span length.
The technical problem to be solved uses following technical scheme to realize:
Wide lip power type rubber oil sea, including oil sealing rubber and metallic framework, oil sealing rubber and metallic framework disposable whole Body sulfidization molding, described oil sealing rubber and a length of 4-7mm of lip of shaft contacts, lip and shaft contacts face are molded with one Bar helical form return wire.
In diameter of axle size according to machine, rotating speed height, casing, the factor such as pressure size can be at lip and shaft contacts The relative one side in face is molded with a helical form return wire.
The a length of 5mm of described lip.
Described metallic framework uses titanium alloy material to make.Titanium alloy intensity is good, can improve service life.
The invention have the benefit that 1, use wide bead structure, improve the lip fit-state to axial plane further, and make Lip is granted the radial direction of axial plane and is seized power and be more evenly distributed, softer, is conducive to promoting lip and the service life of axle;2, wide lip Structure also helps the generation of oil storage film between lip and axial plane, adjusts and maintain, and is an up oil sealing sealing reliability, improves sealing Regional temperature environment, the major technique of the anti-wear performance reducing machine power loss, raising lip and axle support;3, wide lip is used After structure, it is higher that oil sealing adapts to the ability that axle shakes, hole is eccentric, can effectively ensure that in the scope that 0.76mm vibrations and hole are eccentric The sealing of oil sealing;4, seize at lip helical form return wire is set on face, make " pumping power " usefulness of oil sealing embody the brightest Aobvious, auxiliary seal effect further enhances, and seepage probability is greatly lowered, and arranges helical form return wire at lip opposite side, this Sample contributes to improving the pliability of lip, and lip seizes power big I automatic fine tuning;5, elastomeric material is used to avoid Politef unstability;6, the present invention solves that band spring narrow lip type rubber oil sea service life is short, leakage of oil is several Problem that rate is high and politef width lip oil sealing cost of manufacture is high, assembly environment requires high problem, marketing and should Wide by prospect.

Detailed description of the invention:
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below knot Conjunction is specifically illustrating, and the present invention is expanded on further.
As shown in drawings, wide lip power type rubber oil sea, including oil sealing rubber 1 and metallic framework 2, oil sealing rubber can basis Machine difference operating mode selects the disposable overall sulfidization molding of different elastomeric material, oil sealing rubber 1 and metallic framework 2, described oil sealing The a length of 4-7mm of lip 4 that rubber 1 contacts with rotating shaft 3, lip 4 and rotating shaft 3 contact surface are molded with a helical form return wire 5。
In diameter of axle size according to machine, rotating speed height, casing, the factor such as pressure size can connect with rotating shaft 3 at lip 4 The relative one side of contacting surface is molded with a helical form return wire 5.
The described a length of 5mm of lip 4.
Described metallic framework 1 uses titanium alloy material to make.Titanium alloy intensity is good, can improve service life.
Using oil sealing rubber, its stability is better than politef, arranges wide lip and helical form return wire, can strengthen The sealing of oil sealing, can reduce again the oil sealing abrasion to working shaft.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.The technology of the industry Personnel, it should be appreciated that the present invention is not restricted to the described embodiments, simply illustrating this described in above-described embodiment and description The principle of invention, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and these become Change and improvement both falls within scope of the claimed invention.Claimed scope by appending claims and Equivalent defines.
