Description
Technical field
The present invention relates to a kind of Sealing, particularly relate to a kind of low friction damper oil sealing.
Background technique
Vibration damper is parts conventional in modern vehicle, the oil seal structure of vibration damper and the long service life of quality to vibration damper short most important.And the sealability of oil sealing, depend on the thickness of sealing surface oil film, between sealing lip and axle, oil slick thickness is excessive, and oil sealing leaks; Thickness is too small, dry friction may occur, and causes oil sealing and axle wearing and tearing.Automobile in use, often can because oil sealing frictional force causes greatly vibration damper to occur the problems such as leakage of oil, abnormal sound, poor durability.But oil sealing will realize vibration damper internal vibration dampers oil simultaneously, the sealing of pressurized gas, oil sealing is necessarily required again the axle of vibration damper to be produced to the radial force that can overcome vibration damper inner core pressure maximum, General Requirements oil sealing must keep the radial force to vibration damper axle within 3 years or 50,000 kilometers, so, when stem seal design, first the radial force of sealing demand will be met, the long-pending theory of radial force and friction factor is equaled according to frictional force, when radial force design load is larger, under the condition that friction coefficient remains unchanged, large axial friction will inevitably be produced, under the state that axial friction is larger, oil sealing and vibration damper between centers easily produce dry grinding, abnormal sound is damper leakage even, have influence on the travelling comfort of car and the working life of vibration damper.Therefore, how to solve and both ensured suitable radial sealing force, the axial friction that can as far as possible reduce between seal and vibration damper axle just becomes a contradiction again.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, a kind of low friction damper oil sealing is provided.It while guarantee radial seal dynamics, can reduce the axial friction between seal and vibration damper axle, thus extends the working life of seal and even vibration damper.
The technological scheme that the present invention solves the problems of the technologies described above is as follows: a kind of low friction damper oil sealing, comprise skeleton and oil seal body, described oil seal body comprises at least one sealing lip, it is characterized in that, the annular sealing surface that described sealing lip is formed is provided with axial parallel line.Described axial parallel line refers to the basic and parallel to an axis of its lines.
The invention has the beneficial effects as follows: be provided with axial parallel line due on the annular sealing surface that formed at described sealing lip, between sealing surface and vibration damper axle surface of contact, be conducive to forming critical lubricant film, reduce area of contact, be convenient to store lubricant oil to reduce the friction factor between oil sealing and vibration damper axle between axial lines, keeping, under the prerequisite that oil sealing is constant to vibration damper Axial and radial power, reaching the object reducing frictional force between oil sealing and vibration damper axle.
Action principle of the present invention is as follows:
1) parallel line formed axial groove utilize the to-and-fro motion effect of vibration damper axle, lubricant oil (fat) is infiltrated to oil sealing and vibration damper axle contact stress is maximum, the position, oil seal lip tip of the most easily dry grinding, forms critical lubricant film.
2) the original microchannels formed by the line that walks abreast with 1/2 area at the position of vibration damper axle close contact of oil sealing covered, and reduces the area of contact of oil sealing and vibration damper axle, while reducing frictional heat, is also beneficial to heat radiation.
3) axial groove that parallel line is formed is conducive to the storage of lubricating grease and the pcrmanent lubrication at procheilon position.And axially directed effect can be formed to vibration damper axle.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described sealing lip comprises the first sealing lip and the second sealing lip, and the annular sealing surface that described first sealing lip and the second sealing lip are formed is respectively equipped with the first axial parallel line and the second axial parallel line.
The beneficial effect of above-mentioned further scheme is adopted to be according to multi-form oil sealing, corresponding axial parallel line to be set.
Further, described oil seal body also comprises dust excluder lips, and the annular sealing surface that described dust excluder lips is formed is provided with the 3rd axial parallel line.
The beneficial effect of above-mentioned further scheme is adopted to be axial parallel line is set in dust excluder lips and has the effect reducing axial friction equally.
Further, described axial parallel line is the curved shape of wave vertically
Further, described axial parallel line is interrupted straight line type vertically.
Adopt the beneficial effect of above-mentioned further scheme to be conducive to the storage of lubricating grease, and form critical lubricant film.
Further, described axial parallel line section is radially waveform, circular arc, triangle or trapezoidal.
The beneficial effect of above-mentioned further scheme is adopted to be convenient to make, the area of contact between sealing lip and vibration damper axle can be reduced.
Further, described oil seal body is nitrile butadiene rubber, hydrogenated nitrile-butadiene rubber or fluorine rubber.
The beneficial effect of above-mentioned further scheme is adopted to be that the present invention can be adapted to multiple seal body material.
