Abstract
The utility model relates to a kind of Sealing, especially a kind of motor-car dust ring.Comprise the dust-proof inner ring of annular and the dust-proof outer ring of annular, wherein, described dust-proof outer ring is provided with fixed support ring, and described fixed support ring is flexible stainless steel spring steel plate; Dust-proof inner ring is provided with at least one horizontal annular protrusion.Its resistance to pressure, wear resistance and rebound elasticity are good, and sealing effect improves greatly.
Description
Technical field
The utility model relates to a kind of Sealing, especially a kind of motor-car dust ring.
Background technique
At present, dust ring used in existing motor car device as shown in Figure 1, the inner diameter seal of this dust ring adopts whole the mode contacted, therefore the frictional force that is in contact with it between face of the inner ring of dust ring is large, when dust ring pressurized, this surface of contact can produce distortion, is out of shape, occurs gap etc., thus causes leakage, greatly reduces the sealing effect of dust ring.
Model utility content
The purpose of this utility model is the above-mentioned defect overcoming the existence of existing dust ring, and propose a kind of novel motor-car dust ring, its resistance to pressure, wear resistance and rebound elasticity are good, and sealing effect improves greatly.
The utility model adopts following technological scheme to realize: a kind of motor-car dust ring, comprise the dust-proof inner ring of annular and the dust-proof outer ring of annular, wherein, described dust-proof outer ring is provided with fixed support ring, and described fixed support ring is flexible stainless steel spring steel plate; Dust-proof inner ring is provided with at least one horizontal annular protrusion.
In the utility model, the sectional shape of described annular protrusion can be triangle, semicircle or other shapes.
The beneficial effects of the utility model are:
(1) by arranging fixed support ring, improve the compression resistance in wiper seal face;
(2) by arranging annular protrusion, the inner diameter seal making dust ring is linear contact lay, reduces the frictional force of product internal diameter and axle.When product pressurized, sealing surface compression resistance strengthens;
(3) multiple tracks transverse annular convexes to form multi-layer sealed, and has certain buffering between projection, greatly strengthen the resistance to pressure of Total Product, wear resistance, rebound elasticity, improves the sealability of product.
Accompanying drawing explanation
Fig. 1 is the sectional view of dust ring in prior art;
Fig. 2 is sectional view of the present utility model;
Fig. 3 is the partial enlarged drawing of described annular protrusion semicircular in shape;
Fig. 4 is described annular protrusion partial enlarged drawing triangular in shape.
In figure: 1 fixed support ring; 2 annular protrusions.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, described dust ring comprises the dust-proof inner ring of annular and the dust-proof outer ring of annular, and wherein said dust-proof outer ring is provided with fixed support ring 1, and described fixed support ring 1 is for having certain flexible stainless steel spring steel plate; Described dust-proof inner ring is provided with at least one horizontal annular protrusion 2, and the sectional shape of described annular protrusion can be triangle, semicircle, quadrilateral or other shapes.By arranging fixed support ring 1, improve the compressive strength of dust ring; Meanwhile, by arranging annular protrusion, the inner diameter seal making dust ring is linear contact lay, reduces the frictional force of product internal diameter and axle.When product pressurized, sealing surface compression resistance strengthens; Multiple tracks transverse annular convexes to form multi-layer sealed again, and has certain buffering between projection, greatly strengthen the resistance to pressure of Total Product, wear resistance, rebound elasticity, improves the sealability of product.
Claims (2)
1. a motor-car dust ring, comprise the dust-proof inner ring of annular and the dust-proof outer ring of annular, it is characterized in that: described dust-proof outer ring is provided with fixed support ring (1), described fixed support ring (1) is flexible stainless steel spring steel plate; Dust-proof inner ring is provided with at least one horizontal annular protrusion (2).
2. motor-car dust ring according to claim 1, is characterized in that: the sectional shape of described annular protrusion is triangle or semicircle.
