Abstract
The utility model discloses a combined oil seal comprising a framework (2) and a sealing ring, the sealing ring is tightly engaged with the framework (2), and the sealing ring comprises an outer oil seal (4) and an inner oil seal (1), wherein the outer oil seal (4) is connected with an oil cavity via close fit, the inner oil seal (1) is connected with an output shaft (6) via close fit, and the outer oil seal (4) is connected with the inner oil seal (1) via rotary fit. After utilizing the structure and dividing the oil seal into the outer oil seal and the inner oil seal, static seal is achieved between the inner oil seal and the output shaft and between the outer oil seal and the oil cavity, and rotating seal is achieved between the outer oil seal and the inner oil seal, thereby preventing the oil seat abrading the output shaft, and further prolonging service life of the output shaft.
Description
Technical field
The utility model relates to a kind of Sealing, specifically is a kind of combination oil seal that is applicable to automobile.
Background technique
The effect of oil sealing is to be an oil pocket and extraneous the isolation, internally oil sealing, and externally dustproof, it is usually used in the bearing place, particularly roller bearing component of various machineries.General oil sealing comprises skeleton, sealing lip, and sealing lip is supported by skeleton and contacts with running shaft.But the sealing lip of this oil sealing all is one usually, and it is sealed into motive sealing with axle, and grow service time, causes the wearing and tearing of output shaft easily, thereby reveals leakage phenomenon, and therefore, this oil sealing uses a replacing that needs after a period of time to carry out spool, inconvenient maintenance.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of wearing and tearing that can avoid axle, the combination oil seal that prolongs the working life of output shaft.
For solving the problems of the technologies described above, a kind of combination oil seal that the utility model provides, comprise skeleton, seal ring, described seal ring and skeleton are drive fit, described seal ring comprises outer oil seal and inner oil seal, and wherein, described outer oil seal is connected with the oil cavity drive fit, inner oil seal is connected with the output shaft drive fit, and described outer oil seal is rotatably assorted with inner oil seal and is connected.
After adopting above structure, because oil sealing is divided into outer oil seal and inner oil seal, make and be static seal between inner oil seal and the output shaft, it between outer oil seal and the oil cavity static seal, be rotary seal between outer oil seal and the inner oil seal, avoided the wearing and tearing of oil sealing like this, thereby prolonged the working life of output shaft output shaft.
As improvement, the described connection that is rotatably assorted, being meant that outer oil seal inside is provided with main lip, the inner oil seal drive fit has skeleton, described main lip and skeleton drive fit.After adopting this structure, make the cooperating structure of outer oil seal and inner oil seal simpler, sealing effect is better.
As further improvement, described inner oil seal is provided with dust excluder lips, described dust excluder lips and outer oil seal drive fit.After adopting this structure, make this combination oil seal have more the dust-tight function.
Description of drawings
Shown in the drawings is the structural representation of the utility model combination oil seal.
Wherein, 1, inner oil seal; 2, skeleton; 3, dust excluder lips; 4, outer oil seal; 5, main lip; 6, output shaft.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
By the structural representation of this machine of the utility model system shown in Figure 1 as can be known, the utility model combination oil seal, comprise skeleton 2, seal ring, described seal ring and skeleton 2 are drive fit, described seal ring comprises outer oil seal 4 and inner oil seal 1, and wherein, described outer oil seal 4 is connected with the oil cavity drive fit, inner oil seal 1 is connected with output shaft 6 drive fits, and described outer oil seal 4 is rotatably assorted with inner oil seal 1 and is connected.The described connection that is rotatably assorted, be meant that outer oil seal 4 inside are provided with main lip 5, inner oil seal 1 drive fit has skeleton 2, described main lip 5 and skeleton 2 drive fits.Described inner oil seal 1 is provided with dust excluder lips 3, described dust excluder lips 3 and outer oil seal 4 drive fits.That is to say that output shaft 6 and cavity all are to adopt static seal, motive sealing is then adopted in combination oil seal inside, and the power that reaches axle with relatively rotating between two oil sealings is exported, and reaches the effect of sealing with the interference fit of oil sealing inside.
Claims (3)
1, a kind of combination oil seal, comprise skeleton (2), seal ring, described seal ring and skeleton (2) are drive fit, it is characterized in that: described seal ring comprises outer oil seal (4) and inner oil seal (1), wherein, described outer oil seal (4) is connected with the oil cavity drive fit, and inner oil seal (1) is connected with output shaft (6) drive fit, and described outer oil seal (4) is rotatably assorted with inner oil seal (1) and is connected.
2, combination oil seal according to claim 1 is characterized in that: the described connection that is rotatably assorted, being meant that outer oil seal (4) inside is provided with main lip (5), inner oil seal (1) drive fit has skeleton (2), described main lip (5) and skeleton (2) drive fit.
