Abstract
The utility model discloses a kind of special oil sealing of anti-impurity farm machinery, include the oil sealing main body, the inner support that are assembled into one, oil sealing main body be made up of oil-resistant wear-resistant rubber round platform cylindrical shell, be communicated with the cylindrical body made in the oil-resistant wear-resistant rubber of round platform cylindrical shell small-caliber end and form, inner support is made up of cylindric oil-resistant wear-resistant rubber body, and the external wall of cylindric oil-resistant wear-resistant rubber and ring thereof are close to the skeleton being provided with form fit along corresponding surface.The utility model oil sealing adopts radial and axial double seal, can effectively prevent impurity from entering lip, avoid axle because impurity enter wear surface.
Description
Technical field
The utility model relates to oil sealing field, specifically a kind of special oil sealing of anti-impurity farm machinery.
Background technique
China is large agricultural country, and agricultural production occupies core status in historical development process in ancient times all the time, and the farm machinery effect aborning thus as agriculture tool of production is very important.A large amount of model utilitys of farm machinery aspect, reform and apply great effect is played to the raising of social productive forces.And oil sealing is a kind of accurate rubber part of high technology content, be widely used in machinery industry.The stability of oil sealing to complete machine has extremely important effect, though oil sealing is little, performance requirement is harsh.
model utility contentthe purpose of this utility model is to provide a kind of special oil of anti-impurity farm machinery, to solve prior art Problems existing.
In order to achieve the above object, the technological scheme that the utility model adopts is:
A kind of special oil sealing of anti-impurity farm machinery, it is characterized in that: include the oil sealing main body being assembled into one, inner support, the round platform cylindrical shell that described oil sealing main body is made up of oil-resistant wear-resistant rubber, be communicated with the cylindrical body made in the oil-resistant wear-resistant rubber of round platform cylindrical shell small-caliber end to form, and cylindrical body diameter is greater than round platform cylindrical shell small-caliber end diameter, cylindrical body and round platform cylindrical shell connectivity part form the protrusion cylindrical part stretched in cylindrical body, cylindrical body inwall is close to the skeleton being provided with form fit, described protrusion cylindrical part outer wall forms annular groove, and annular extension spring is installed in annular groove, described inner support is made up of cylindric oil-resistant wear-resistant rubber body, the nozzle edge, one end of cylindric oil-resistant wear-resistant rubber body forms ring edge, the cylindric external wall of oil-resistant wear-resistant rubber and ring thereof are close to the skeleton being provided with form fit along corresponding surface, its cylindric oil-resistant wear-resistant rubber body of described inner support penetrates also close-fitting from round platform cylindrical shell heavy caliber end and is protruding cylindrical part, and inner support cylindric oil-resistant wear-resistant rubber body cylinder end passes from cylindrical body.
The special oil sealing of described a kind of anti-impurity farm machinery, is characterized in that: cylindrical body and round platform cylindrical shell connectivity part form the protrusion frustum cone cylinder body stretched in round platform cylindrical shell.
The special oil sealing of described a kind of anti-impurity farm machinery, is characterized in that: protrude cylindrical part inwall and form multiple tracks annular protrusion, and annular protrusion diameter and protrusion frustum cone cylinder body small-caliber end equal diameters.
The utility model oil sealing adopts radial and axial double seal, can effectively prevent impurity from entering lip, solve axle because impurity enter wear surface, thus cause the inefficacy of axle and have influence on the problem of the stability of the overall performance of agricultural machinery, it also avoid lubricant oil simultaneously and outwards ooze out.
