Description
Technical field
The utility model belongs to axial section oil seal technique field, and in particular to a kind of dust-protection type axial section oil sealing.
Background technique
Axial section oil sealing is generally used for axial section oil-leakage-prevention, the dust and water protection of the equipment such as electrode axis, can protect in equipment
The components in portion.Axial section oil sealing all includes the sealing ring of rubber material, in use, the frictional force between sealing ring and axis will
So that the rotation of axis needs to overcome certain frictional resistance, the energy consumption of equipment will be increased.And existing axial section oil sealing is gone back mostly
The defects of it is inadequate that there are intensity, and dust-proof effect is bad.
Summary of the invention
Reasonable and strong applicability the dust-protection type axial section oil sealing the purpose of the utility model is to provide a kind of structure setting.
The technical solution for realizing the utility model aim is a kind of dust-protection type axial section oil sealing, including oil sealing shell and is sticked
Rubber oil sea body on the oil sealing outer casing inner wall is fixed with annular groove on the inner wall of the oil sealing shell, described
It is L-shaped two press blocks that section is provided in annular groove, and two press blocks are semicircular body and two press blocks are combined into one
A full circle body compresses ring, and full circle compresses internal diameter of the internal diameter less than oil sealing shell of ring, recessed in the press block and the annular
It is fixed between the end wall of slot and compresses spring, the edge of axial section is caught in the turning of L-shaped press block, the rubber oil sea body
On the lateral surface and end face for riding over axial section under the action of press block.
It is fixed with annulus in the end of the rubber oil sea body, the annulus is fitted on the end face of axial section, the circle
Ring is on the outside of L-shaped press block.
The dust-proof protrusion of V-arrangement is fixed in the lateral surface of the annulus.
The oil sealing shell is carbon steel material shell and the rubber oil sea body and annulus are integrally formed.
The utility model has the effect of positive: the structure setting of the utility model is reasonable, when in use by rubber oil
Envelope body is set on axis, and is pressed in the rubber oil sea body card on the inside of L-shaped press block between the side of axial section and end face,
The effect of dust-proof leak-proof can be effectively improved, and be provided with and compress spring, in axis rotation, can also carried out conducive to centrifugal force
Small range of compression, so as to reduce the frictional resistance between rubber oil sea body and axis, be conducive to raising axis uses the longevity
Life, use is reliable and stable, strong applicability and practicability is good.
Detailed description of the invention
In order to be more likely to be clearly understood the content of the utility model, below according to specific embodiment and combine attached
Figure, is described in further detail the utility model, in which:
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
(embodiment 1)
Fig. 1 shows a kind of specific embodiment of the utility model, and wherein Fig. 1 is the structural representation of the utility model
Figure.
See that Fig. 1, a kind of dust-protection type axial section oil sealing including oil sealing shell 1 and are sticked on the oil sealing outer casing inner wall
Rubber oil sea body 2 is fixed with annular groove 3 on the inner wall of the oil sealing shell 1, is provided with section in the annular groove
For L-shaped two press blocks 4, two press blocks are semicircular body and two press blocks are combined into a full circle body and compress ring, and whole
Circle compress ring internal diameter be less than oil sealing shell internal diameter, be fixed between the press block and the end wall of the annular groove to
Pressing spring 5, the edge of axial section are caught in the turning of L-shaped press block, and the rubber oil sea body pastes under the action of press block
It is pressed on the lateral surface and end face of axial section.
It is fixed with annulus 6 in the end of the rubber oil sea body, the annulus is fitted on the end face of axial section, the circle
Ring is on the outside of L-shaped press block.
V-arrangement dust-proof raised 7 is fixed in the lateral surface of the annulus.
The oil sealing shell is carbon steel material shell and the rubber oil sea body and annulus are integrally formed.
The structure setting of the utility model is reasonable, and rubber oil sea body is set on axis when in use, and makes L-shaped
Rubber oil sea body card on the inside of press block is pressed between the side of axial section and end face, can effectively improve the effect of dust-proof leak-proof
Fruit, and be provided with and compress spring, in axis rotation, small range of compression can also be carried out conducive to centrifugal force, so as to
The frictional resistance between rubber oil sea body and axis is reduced, is conducive to the service life for improving axis, use is reliable and stable, strong applicability
And practicability is good.
Obviously, the above embodiments of the present invention is merely examples for clearly illustrating the present invention, and
It is not limitations of the embodiments of the present invention.For those of ordinary skill in the art, in above description
On the basis of can also make other variations or changes in different ways.There is no need and unable to give all embodiments
Exhaustion.And the obvious changes or variations that these connotations for belonging to the utility model are extended out still fall within it is practical
Novel protection scope.
