Abstract
The present invention provides a kind of hydraulic motor High-pressure oil sealing, it include: oil sealing ontology and to be moulded in the intrinsic skeleton of the oil sealing, the first seal lip and second lip of seal are provided on the inside of the oil sealing ontology, the oil sealing ontology is equipped with elastic collar on the outside of the second lip of seal, is provided with sealing flange on the side end face of the oil sealing ontology.Hydraulic motor High-pressure oil sealing of the present invention is sealed by the sealing flange in 2 seal lips and side end face, is capable of forming biggish sealing pressure, and whole structure is simple, and it is convenient to realize, the sealing effect reached is good.
Description
Technical field
The present invention relates to a kind of hydraulic motor, in particular to a kind of hydraulic motor High-pressure oil sealing.
Background technique
Hydraulic motor, is a kind of executive component of hydraulic system, and the liquid pressure energy that it provides hydraulic pump is changed into it
The mechanical energy (torque and revolving speed) of output shaft.Hydraulic motor is also known as oil motor, is mainly used in injection machine, ship, rises and raise
Machine, engineering machinery, building machinery, coal mine machinery, mining machinery, metallurgical machinery, ship machinery, petrochemical industry, harbour machinery etc..
Oil sealing sealing pressure on the existing some hydraulic motors used is smaller, and sealing performance is not strong.
Summary of the invention
(1) technical problems to be solved
A kind of the technical problem to be solved in the present invention is to provide sealed pressures hydraulic motor big, that overall sealing performance is good
High-pressure oil sealing.
(2) technical solution
In order to solve the above technical problems, the present invention provides a kind of hydraulic motor High-pressure oil sealing, comprising: oil sealing ontology and injection molding
It is provided with the first seal lip and second lip of seal on the inside of the intrinsic skeleton of the oil sealing, the oil sealing ontology, it is described
Oil sealing ontology is equipped with elastic collar on the outside of the second lip of seal, is provided on the side end face of the oil sealing ontology close
Seal flange.
(3) beneficial effect
Hydraulic motor High-pressure oil sealing of the present invention is sealed by the sealing flange in 2 seal lips and side end face, energy
Biggish sealing pressure is enough formed, whole structure is simple, and it is convenient to realize, the sealing effect reached is good.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of hydraulic motor High-pressure oil sealing of the present invention；
Wherein: 1 be oil sealing ontology, 2 be skeleton, 3 be the first seal lip, 4 be second lip of seal, 5 be elastic collar,
6 it is side end face, 7 is sealing flange.
Specific embodiment
Refering to fig. 1, the present invention provides a kind of hydraulic motor High-pressure oil sealing, comprising: oil sealing ontology 1 and is moulded in the oil sealing
Skeleton 2 in ontology 1 is provided with the first seal lip 3 and second lip of seal 4, the oil sealing sheet on the inside of the oil sealing ontology 1
Body 1 is equipped with elastic collar 5 in the outside of the second lip of seal 4, is provided on the side end face 6 of the oil sealing ontology 1 close
Seal flange 7.
The present embodiment hydraulic motor High-pressure oil sealing is sealed by the sealing flange in 2 seal lips and side end face,
It is capable of forming biggish sealing pressure, whole structure is simple, and it is convenient to realize, the sealing effect reached is good.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvements and modifications can also be made, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
