Abstract
The utility model relates to a sealing element especially relates to the improvement of skeleton oil blanket. The utility model discloses dustproof skeleton oil blanket that following nature is good, including the skeleton, one side of this skeleton is connected with waist and lip, the lip is installed and is enclosed the spring, the opposite side of skeleton is equipped with dust lip, this dust lip with being connected with the compensation waist of crooked shape between the skeleton, should compensating waist smooth transition everywhere, the thickness that just should compensate the waist does 35~34 of dust lip thickness. It still can keep better dustproof effect when the rotation axis is eccentric.
Description
Technical field
This utility model relates to potted component, particularly relates to the improvement of outside framework oil seal.
Background technology
Outside framework oil seal is because of its simple in construction, effect is notable, safeguard and change convenient and be widely used in machinery, chemical industry, etc. all trades and professions, existing outside framework oil seal includes skeleton, the side of skeleton is connected to waist and lip, lip is provided with and encloses spring, the opposite side of skeleton is connected to dust excluder lips, dust excluder lips thickness everywhere is roughly equal, and its end and axle gentle touchdown, enter for blocks dust, though the outside framework oil seal of this structure can play good sealing function, but the followability of dust excluder lips is not as, when axle occurs that eccentric phenomena is beated for various reasons, dust excluder lips will be pulled and draw, cause that circle is lost in dust excluder lips deformation, and and axle between form bigger gap, this directly contributes dust and enters between lip and axle by gap and lip is caused heavy wear, make the decline of the sealing effectiveness of outside framework oil seal and have a strong impact on the service life of outside framework oil seal. the followability of current outside framework oil seal dust excluder lips better, the outside framework oil seal that can better improve dust-proof effect still rare.
Utility model content
For prior art above shortcomings, the purpose of this utility model is to provide for the dust-proof outside framework oil seal that a kind of followability is good, and it remains to when rotating shaft eccentric keep good dust-proof effect.
In order to solve above-mentioned technical problem, this utility model solves the scheme of technical problem: the dust-proof outside framework oil seal that followability is good, including skeleton, the side of this skeleton is connected to waist and lip, described lip is provided with and encloses spring, and the opposite side of described skeleton is provided with dust excluder lips, is connected to the compensation waist of curved shape between this dust excluder lips and described skeleton, this compensation waist seamlessly transits everywhere, and the thickness of this compensation waist is described dust excluder lips thickness 3/5��3/4.
After adopting such scheme, owing to being connected to the compensation waist of curved shape between dust excluder lips and described skeleton, this compensation waist seamlessly transits everywhere, and the thickness of this compensation waist is described dust excluder lips thickness 3/5��3/4, thus the elastic force 1. compensating waist is substantially reduced, and be significantly less than that dust excluder lips deformation loses axle suffered by bowlder pull power; 2. the curved shape compensating waist is that each of dust excluder lips provides bigger nargin and possibility to radial displacement; 3. compensate waist to seamlessly transit everywhere, being also not easily tied even if producing high-frequency buckling, reducing the damage to dust excluder lips. So the followability that this utility model makes dust excluder lips is significantly improved, improves dust seal effect and the service life of dust excluder lips preferably, improve the comprehensive quality of outside framework oil seal preferably.
Corrosive gas and liquid that chemical industry is also likely produced by dust excluder lips have certain barrier effect.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the dust-proof outside framework oil seal that this utility model followability is good is described in further detail.
Fig. 1 is the front view of the structural principle schematic diagram of the dust-proof outside framework oil seal that this utility model followability is good.
Detailed description of the invention:
In Fig. 1, the dust-proof outside framework oil seal that followability is good, including skeleton 3, the side of skeleton 3 is connected to waist 4 and lip 6, described lip 6 is provided with and encloses spring 5, and the opposite side of described skeleton 3 is provided with dust excluder lips 1, is connected to the compensation waist 2 of curved shape between this dust excluder lips 1 and described skeleton 3, this compensation waist 2 seamlessly transits everywhere, and the thickness of this compensation waist 2 is described dust excluder lips 1 thickness 3/5��3/4. Owing to being connected to the compensation waist 2 of curved shape between dust excluder lips 1 and described skeleton 3, this compensation waist 2 seamlessly transits everywhere, and the thickness of this compensation waist 2 is described dust excluder lips 1 thickness 3/5��3/4, thus the elastic force 1. compensating waist 2 is substantially reduced, and it is significantly less than the power of pullling of dust excluder lips 1 deformation mistake axle suffered by bowlder; 2. the curved shape compensating waist 2 is that each of dust excluder lips 1 provides bigger nargin and possibility to radial displacement; 3. compensate waist 2 to seamlessly transit everywhere, being also not easily tied even if producing high-frequency buckling, reducing the damage to dust excluder lips 1. So the followability that this utility model makes dust excluder lips 1 is significantly improved, improves dust seal effect and the service life of dust excluder lips 1 preferably, improve the comprehensive quality of outside framework oil seal preferably.
