Description
Technical field
The utility model is related to a kind of sealing ring, particularly water pump wear-resistant seal circle.
Background technology
Water pump shaft connecting bearings, connection impeller and motor are required for sealing ring, and current existing water pump bearing mainly includes
Outer ring and mandrel, impeller are fixed on one end of mandrel, and motor is fixed on the other end of mandrel, is provided between outer ring and mandrel
Ball, is provided with the raceway groove placed for ball on outer ring and mandrel, existing water pump bearing, because mandrel is more long, therefore, outside
Double row ball is provided between circle and mandrel, double row ball can play preferably support to mandrel, realize the stable rotation of mandrel.
Existing water pump shaft connecting bearings, mostly the two ends in outer ring sealing ring is set and realizes the sealing of water pump shaft connecting bearings,
But existing bearing sealed ring, mainly including steel bracket, is coated with rubber ring on steel bracket, the mandrel of rubber ring is provided with close
Envelope lip, after installing, the outer ring clamping of rubber ring and bearing, when actually used, bearing sealed ring and outer ring clamping are close
Envelope lip is abutted with mandrel, realizes the sealing of bearing, and this bearing sealed ring is only merely to be provided with one layer of sealing when in use
Lip is used as sealing, and sealing effectiveness is not good, is susceptible to leakage, reduces the sealing of water pump shaft connecting bearings, and sealing lip holds
Easily wear and tear, the service life of bearing sealed ring is very low.
Utility model content
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of water pump bearing of good airproof performance
Sealing ring.
To achieve the above object, the utility model provides following technical scheme：
Water pump wear-resistant seal circle, including annular support, sealing is provided with the outer rim side wall of described annular support
Flanging ring, described sealing flanging ring is connected with the inner wall sealing of bearing；There is ring on the interior ring-side wall of described annular support
The groove of shape, is provided with the elastic inner seal ring of annular in described annular groove, be filled between elastic inner seal ring and annular groove
Oil, elastic inner seal ring can be rotated in annular groove；The interior ring-side wall of described elastic inner seal ring and axle interference fit.
Propped up towards annular the opening for having half fluting of annular, half described fluting on described annular support both sides end face
The outer rim side wall of support body, the root of half fluting is arc or inclined-plane；Described sealing flanging ring cross section is half-open mouth-shaped,
Including top surface and two flangings, described sealing flanging ring set is on the outer rim side wall of annular support；Two described flangings
Respectively in half fluting of annular support two sides, described hemmed edges are squeezed in the root arc of half fluting or oblique
On face.
The outer rim side wall of described elastic inner seal ring has multiple annular concave-convex lines；Described annular concave-convex line with it is described
Bottom land sealing sliding contact in annular support on ring-side wall, and filled with lubricating oil.
The water pump wear-resistant seal circle that the utility model is provided, due to there is groove on the interior ring-side wall of annular support, in elasticity
Sealing ring is rotated in groove, and elastic inner seal ring and between centers are in interference fit, and elastic inner seal ring is rotated with axle, is reduced
The occurrence of ring wear, so as to extending the service life of sealing ring.Elastic inner seal ring is made of fluorubber,
Annular support is made of silicon carbide ceramics, is difficult to be corroded, and keeps material surface smooth, reduces frictional force.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is partial enlargement structural representation of the present utility model.
Specific embodiment
The utility model is elaborated with example below in conjunction with the accompanying drawings.As shown in figure 1,
Water pump wear-resistant seal circle, including annular support 3, are provided with close on the outer rim side wall of described annular support 3
Envelope flanging ring 4, described sealing flanging ring 4 is connected with the inner wall sealing of bearing 1；The interior ring-side wall of described annular support 3
On have the groove of annular, the elastic inner seal ring 5 of annular is installed in described annular groove, elastic inner seal ring 5 and annular groove it
Between filled with oil, elastic inner seal ring 5 can rotate in annular groove；The interior ring-side wall of described elastic inner seal ring 5 and axle 2
Interference fit, elastic inner seal ring 5 and axle are rotated together, and the remains stationary of annular support 3.
As shown in Fig. 2 have half fluting 31 of annular on the described both sides end face of annular support 3, half described fluting 31
Opening towards annular support 3 outer rim side wall, the root of half fluting 31 is arc or inclined-plane；
The described cross section of sealing flanging ring 4 is half-open mouth-shaped, including top surface 42 and two flangings 41, described sealing
Flanging ring 4 is enclosed within the outer rim side wall of annular support 3；Two described flangings 41 are located at the two sides of annular support 3 respectively
Half fluting 31 in, the described edge of flanging 41 is squeezed on the root arc of half fluting 31 or inclined-plane.
By extruding, promote sealing flanging ring 4 to keep being fully contacted with the inwall of bearing 1, play sealing function.
The outer rim side wall of described elastic inner seal ring 5 has multiple annular concave-convex lines 51；Described annular concave-convex line 51 with
Bottom land sealing sliding contact in described annular support 3 on ring-side wall, and filled with lubricating oil.
Annular concave-convex line 51 reduce contact area, and between also fill up lubricating oil, can play oil sealing effect, moreover it is possible to rise
To lubrication, abrasion between the two is reduced.
