Description
Technical field
The present invention relates to rubber oil sea technical fields, more particularly to a kind of coating side of rubber oil sea lip mouth PTFE coating
Method.
Background technique
Traditional oil sealing is largely used to automobile engine, speed change since structure is simple, advantage of lower cost at present
Each significant points such as case.But it is increasingly strict with environmental requirements such as the energy consumption of automobile, discharges, as one of auto parts
Oil sealing is also required to further decrease frictional dissipation, to adapt to environmental requirement.
The force of sliding friction of oil sealing and axis is that (μ coefficient of sliding friction between oil seal lip and axis, FN are oil sealing to F=μ FN
To the enclasping force of axis), oil seal lip shape centainly under the premise of (i.e. FN is constant), by reducing friction coefficient μ, can reach reduction
The purpose of frictional force.
PTFE is generally acknowledged low friction coefficient materials, and researcher, which is studying, at present is sprayed at oil seal lip for PTFE material
The method of discharge surface, so that the friction coefficient mu between oil seal lip and axis is reduced, so that reducing reduces frictional force to drop
Low friction loss.
Summary of the invention
The technical problems to be solved by the present invention are: in order to overcome the shortcomings in the prior art, the present invention provides a kind of rubber
The coating method of glue oil seal lip PTFE coating.
The present invention solves its technical problem technical solution to be taken: a kind of painting of rubber oil sea lip mouth PTFE coating
Cloth method, comprising the following steps:
Fixed rubber oil sea: rubber oil sea level is set on workbench, workbench drives under the action of servo motor
Rubber oil sea is rotated along axis；
Rubber oil sea rotates under the drive of workbench along axis, can make PTFE liquid of the spray gun spraying on lip more
Uniformly.
It adjusts Burners Positions: spray gun is set to above workbench, adjust the angle and distance between spray gun and rubber oil sea,
So that spray gun is directed at rubber oil sea lip position, spray gun is facilitated to spray PTFE layers on rubber oil sea lip；
The spraying of PTFE liquid: servo motor drives rubber oil sea along axis uniform rotation, and spray gun is to rubber oil sea lip
PTFE liquid is sprayed, the PTFE liquid for being ejected into lip is atomized under the influence of centrifugal force, and the PTFE drop after atomization is due to table
Area increases, and the volatile solvent in PTFE liquid volatilizees rapidly, makes the uniform primary solidification of PTFE on lip, in conjunction with injection
Time, when the PTFE layer sprayed on rubber oil sea lip reaches 3~10 μm stop spraying；
PTFE layers solidify: the rubber oil sea sprayed taking-up, which is placed in 12~24H of heating, heating temperature in heater box, is
150 DEG C~220 DEG C, PTFE layers are made permanent to be solidificated on rubber oil sea lip.
Further, in step b, the distance between spray gun and rubber oil sea lip are 1mm~5mm, the spray angle of spray gun
Angle between plane where rubber oil sea is 20 °~40 °.
Further, in step c, servo motor drives rubber oil sea to rotate along axis with the frequency of 25~50Hz, spray gun with
The flow of 0.05g/s~0.2g/s sprays PTFE liquid to rubber oil sea lip.
The beneficial effects of the present invention are: a kind of coating method of rubber oil sea lip mouth PTFE coating provided by the invention, is adopted
With to along the rubber oil sea lip that axis rotates spray PTFE drop, after the volatile solvent in PTFE liquid volatilize rapidly at the beginning of
Step is solidificated on lip, is made to be solidificated in PTFE layer of lip and is reached suitable thickness, then by further heating, make PTFE layers permanently
Be solidificated on lip.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the structural schematic diagram of preferred embodiment；
Fig. 2 is the structural schematic diagram of rubber oil sea.
In figure: 1, rubber oil sea, 1-1, lip, 2, spray gun, 3, workbench.
Specific embodiment
Presently in connection with attached drawing, the present invention is described in detail.This figure is simplified schematic diagram, is only illustrated in a schematic way
Basic structure of the invention, therefore it only shows the composition relevant to the invention.
As shown in Figs. 1-2, the coating method of a kind of rubber oil sea lip mouth PTFE coating of the invention, comprising the following steps:
Fixed rubber oil sea 1: rubber oil sea 1 is horizontal on workbench 3, and workbench 3 is under the action of servo motor
Rubber oil sea 1 is driven to rotate along axis；
Adjust 2 position of spray gun: spray gun 2 be set to the top of workbench 3, adjust angle between spray gun 2 and rubber oil sea 1 and
Distance makes spray gun 2 be directed at 1 position lip 1-1 of rubber oil sea, spray gun 2 is facilitated to spray PTFE layers on 1 lip 1-1 of rubber oil sea；
The spraying of PTFE liquid: servo motor drives rubber oil sea 1 along axis uniform rotation, and spray gun 2 is to 1 lip of rubber oil sea
Mouth 1-1 sprays PTFE liquid, and the PTFE liquid for being ejected into lip 1-1 is atomized under the influence of centrifugal force, the PTFE liquid after atomization
Since surface area increases, the volatile solvent in PTFE liquid volatilizees rapidly drop, makes the uniform primary solidification of PTFE in lip 1-1
On, in conjunction with the time of injection, stop spraying when the PTFE layer sprayed on 1 lip 1-1 of rubber oil sea reaches 6 μm；
