Abstract
The utility model discloses a rotary shaft lip seal, which comprises an annular shaft sleeve, a main seal element, an auxiliary seal element, a framework, an inner positioning sleeve and an outer positioning sleeve. The lower part of the main seal element is provided with a dustproof lip contacted with the surface of the shaft sleeve. The utility model has the advantages of good leak tightness, capabilities of preventing dust and blocking engine oil, and long service life.
Description
Technical field
The utility model relates to a kind of seal ring, particularly a kind of seal ring that is enclosed within on the running shaft.
Background technique
Our company has applied for that on 07 25th, 2007 name is called " a kind of rotary shaft lip seal ", and the patent No. is: the utility model patent of " 200720127833.X ".There was the improved aspect of some needs in effect aspect sealing effect in this patent under some special operation condition and retaining were oily.Might there be the situation of machine oil of seepage or several machine oil in existing rotary shaft lip seal after machine stops, the machine oil that often is exactly this seepage is considered to leakage of oil, causes the increase of the reduction of product quality in customers and the cost of client's replacing.
Summary of the invention
At the deficiency of existing seal ring retaining oil and seal aspect, the utility model provides a kind of rotary shaft lip seal.
To achieve these goals, technical solution adopted in the utility model is: a kind of rotary shaft lip seal, the axle sleeve, primary seal, auxilliary Sealing, skeleton and interior setting sleeve and the outside fix cover that comprise annular, the primary seal bottom is provided with a dust excluder lips that contacts with the axle sleeve surface, and dust excluder lips has formed double sealing with auxilliary Sealing.
Protruding formation one oil baffle structure in axle sleeve inner top side edge has been strengthened the intensity of axle sleeve itself simultaneously.
The beneficial effects of the utility model: aspect dustproof, taking the two seals defence line, getting rid of the oil leakage phenomenon that causes under the special condition of severe of dust externally; Strengthened the intensity of axle sleeve with strengthened the oily effect of retaining; The structure of axle sleeve has reduced crank processing precision of motor own and surface roughness, has reduced cost of production; An optimal seal solution that can adapt to the equipment of badly working down more at the dust environment.Better tightness can prevent that dust from entering, and can block the machine oil that splashes in addition to the direct impact of primary seal, longer service life.

Embodiment
As shown in Figure 1, the utility model integral body is a circle structure, do not draw among the figure, and can with reference to the patent No. of our company the utility model patent of 200720127833.X.A kind of rotary shaft lip seal, axle sleeve 2, primary seal 4, auxilliary Sealing 6, skeleton 1 and the interior setting sleeve 7 and the outside fix cover 3 that comprise annular, primary seal 4 bottoms are provided with a dust excluder lips 5 that contacts with axle sleeve 2 surfaces, and dust excluder lips 5 has formed double sealing with auxilliary Sealing 6.Dust excluder lips 5 stretch out just in time terminal opposite with primary seal 4 of direction, auxilliary Sealing 6 is generally felt, the dust that friction produced between auxilliary Sealing 6 and the axle sleeve 2, the perhaps dust that enters outward of seal ring, the obstruct by dust excluder lips 5 just can prevent that dust from entering in the seal ring.Protruding formation one oil baffle structure in axle sleeve 2 inner top side edges, just the upper end of axle sleeve 2 inner rings bends to the outer ring direction, suitable for reading like this narrowing down, machine oil is not easy to splash into primary seal 4, and machine oil is blocked.
Claims (2)
1. rotary shaft lip seal, the axle sleeve (2), primary seal (4), auxilliary Sealing (6), skeleton (1) and interior setting sleeve (7) and the outside fix cover (3) that comprise annular, it is characterized in that, primary seal (4) bottom is provided with a dust excluder lips (5) that contacts with axle sleeve (2) surface, and dust excluder lips (5) has formed double sealing with auxilliary Sealing (6).
