Abstract
The utility model discloses a water seal sealing washer, including bracing ring, outer lip and epipharynx, the bracing ring is the tourus, the outer lip is connected in bracing ring excircle one side, circle one side in the bracing ring is connected to the epipharynx, the lip department of outer lip still is equipped with the outer lip chamfer. The utility model discloses simple structure, easily preparation, realized in the installation with the flexible installation of shell and axle, reduced the installation degree of difficulty, improved the durability and the reliability of product.
Description
Technical field
The utility model relates to sealed member technical field, relates in particular to a kind of water-sealing sealing ring.
Background technique
Water seal conventional on existing market comprises outer lip and inner lip, wherein, outer lip be positioned at water seal cylindrical, with casing interference fit; Inner lip be positioned at water seal inner circle, with running shaft interference fit.Thus realize water seal to be arranged on the water-stop effect needing sealing place, realize between running shaft and casing.In practice, be installed on outside running shaft and internal side of shell because water seal is synchronous realization, because between the epipharynx of water seal and axle, all adopt interference fit between outer lip and casing, be easy to cause in installation process, water seal is difficult to be inserted in axle and casing or unbalance stress causes water seal location dislocation in the process of being inserted in.How to solve the problem is the problem that those skilled in the art should carry out creative thinking.
Model utility content
For solving the problem, the utility model provides a kind of water-sealing sealing ring.
Concrete technological scheme of the present utility model is as follows:
A kind of water-sealing sealing ring, comprise bracing ring, outer lip and epipharynx, described bracing ring is cirque body, and described outer lip is connected to bracing ring cylindrical side; Described epipharynx is connected to bracing ring inner circle side; The lip place of described outer lip is provided with outer lip chamfering.
By adopting this technological means: in installation process, utilize the extra outer lip chamfering arranged on outer lip, along chamfering direction water-sealing sealing ring progressively clamp-oned in the gap between casing and axle, thus achieve the flexible installing of water-sealing sealing ring in installation process between water-sealing sealing ring and casing, thereby reduce installation difficulty, and evade the problem of the water seal dislocation caused further because being difficult to install.
Preferably, in above-mentioned water-sealing sealing ring: the lip place of described epipharynx is provided with epipharynx chamfering.
By adopting this technological means: furthermore achieved that the flexible installing in installation process between water-sealing sealing ring and axle, further reduce installation difficulty.
It is further preferred that in above-mentioned water-sealing sealing ring: the chamfer angle of described outer lip chamfering and epipharynx chamfering is 30 °-60 °.
Further preferably, in above-mentioned water-sealing sealing ring: the chamfer angle of described outer lip chamfering and epipharynx chamfering is any one of 30 °, 45 °, 60 °.
Compared with prior art, the utility model structure is simple, is easy to preparation, achieves this product and the flexible installing of shell, axle in installation process, reduces installation difficulty, improve serviceability and the reliability of product.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment 1;
In above-mentioned accompanying drawing, the corresponding relation of each parts and reference character is as follows:
1, bracing ring; 2, outer lip; 3, epipharynx; 21, outer lip chamfering; 31, epipharynx chamfering.
Embodiment
In order to be illustrated more clearly in the technical solution of the utility model, below in conjunction with accompanying drawing, the utility model is further described.
The utility model embodiment 1 as shown in Figure 1:
A kind of water-sealing sealing ring, comprises bracing ring 1, outer lip 2 and epipharynx 3, described bracing ring 1 in cirque body, described outer lip (2) be connected to bracing ring 1 cylindrical side, when mounted with the aperture interference fit on casing; Described epipharynx 3 be connected to bracing ring 1 inner circle side, when mounted with running shaft interference fit; The lip place of described outer lip 2 is provided with outer lip chamfering 21, and the lip place of described epipharynx 3 is provided with epipharynx chamfering 31.The chamfer angle of outer lip chamfering 21 adopts 45° angle, and the chamfer angle of epipharynx chamfering 31 adopts 45° angle.
In practice: utilize outer lip chamfering 21 and epipharynx chamfering 31, water-sealing sealing ring is progressively clamp-oned in the gap between casing and axle, thus the flexible installing achieved between the outer lip 2 of water-sealing sealing ring and casing and the flexible installing between epipharynx 3 and axle, decrease installation difficulty.
The above; be only specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; the technician of any skilled is in technical scope disclosed in the utility model; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with the protection domain of claims.
