Description
Technical field
The utility model is related to automobile, technical field of engineering machinery, and in particular to a kind of Combined grease seal.
Background technology
Currently, combination oil seal mostly uses the structure that common skeleton adds seal, there is sealing position grease leakage more
The problem of.
Utility model content
The purpose of this utility model is to provide a kind of Combined grease seals, to solve the problems, such as sealing position grease leakage.
To achieve the above object, the utility model provides a kind of Combined grease seal, including the outer oil seal of intercombination and interior
Oil sealing, outer oil seal are connected with the first skeleton, and inner oil seal and the second skeleton are connected, and inner oil seal is provided with spring, the first skeleton
It is connected respectively with the second skeleton and third skeleton；The rubber bodies of inner oil seal are set as knurl type structure, the rubber lip of outer oil seal
It is provided with sealed muscle on the contact surface that mouth is in contact with metal；First skeleton is the warp architecture of horizontal serpentine, the first skeleton
Bending place be right-angle structure, the second skeleton be horizontal " L " shape structure, the bending structure of the first skeleton to raise up it is upper
End is connected with the lateral part of the second skeleton, and the longitudinal component of the second skeleton extends downwardly；Third skeleton is set as inverted "L" shape
The longitudinal component of structure, third skeleton extends downwardly, the outer wall of the longitudinal component of third skeleton and the first skeleton to lower recess
The inner left wall of warp architecture be connected, the lateral part of third skeleton extends to the right；The bending place of third skeleton is provided with
Second level bending structure.
Optionally, knurl type structure is hatching knurling structure.
Optionally, sealed muscle is wave structure.
The utility model has the following advantages that：
The Combined grease seal of the utility model can solve the problems, such as sealing position grease leakage, can preferably prevent
Dirt prevents grease leakage.
Description of the drawings
Fig. 1 is the structural schematic diagram of the Combined grease seal of the utility model.
In figure, 1 is outer oil seal, and 2 be inner oil seal, and 3 be the first skeleton, and 4 be the second skeleton, and 5 be spring, and 6 be third skeleton,
7 be knurl type structure, and 8 be sealed muscle.
Specific implementation mode
The following examples illustrate the utility model, but is not intended to limit the scope of the present invention.
Embodiment
A kind of Combined grease seal, referring to the outer oil seal 1 and inner oil seal 2 of Fig. 1, including intercombination, outer oil seal 1 and the first bone
Frame 3 is connected, and inner oil seal 2 is connected with the second skeleton 4, and inner oil seal 2 is provided with spring 5, the first skeleton 3 respectively with the second skeleton
4 are connected with third skeleton 6；The rubber bodies of inner oil seal 2 are set as knurl type structure 7, the rubber lip and metal phase of outer oil seal 1
Sealed muscle 8 is provided on the contact surface of contact；First skeleton 3 is the warp architecture of horizontal serpentine, the bending of the first skeleton 3
Place be right-angle structure, the second skeleton 4 be horizontal " L " shape structure, the upper end for the bending structure of the first skeleton 3 to raise up with
The lateral part of second skeleton 4 is connected, and the longitudinal component of the second skeleton 4 extends downwardly；Third skeleton 6 is set as inverted "L" shape
The longitudinal component of structure, third skeleton 6 extends downwardly, and the outer wall of the longitudinal component of third skeleton 6 and the first skeleton 3 are to recessed
The inner left wall of sunken warp architecture is connected, and the lateral part of third skeleton 6 extends to the right；The bending place of third skeleton 6 is set
It is equipped with second level bending structure.
As it can be seen that the Combined grease seal of the present embodiment, knurl type structure 7 combines other structures, during mechanical movement
Frictional force can be increased, prevents machinery from skidding when the rubber face of metal and rubber bodies contacts in the process of running, avoids causing machine
Tool fails when operating；It is provided with sealed muscle 8 on the contact surface that the rubber lip of outer oil seal 1 is in contact with metal, it is rubber lip, close
Envelope muscle 8 and knurl type structure 7 are used cooperatively, can be preferably dust-proof, prevent grease leakage.
Preferably, knurl type structure 7 is hatching knurling structure.
Preferably, sealed muscle 8 is wave structure.
It should be noted that the Combined grease seal of the utility model, mainly improves above structure, other are not carried
And function, component and structure, when needed, may be used the component that can realize corresponding function in the prior art and structure into
Row is implemented.
Although above having made detailed description to the utility model with generality explanation and specific embodiment,
On the basis of the utility model, it can be made some modifications or improvements, this is apparent to those skilled in the art
's.Therefore, these modifications or improvements on the basis of without departing from the spirit of the present invention, belong to the utility model and want
Seek the range of protection.
