Abstract
The utility model relates to a seal structure of cooling water pump of automobile engine, comprising a bellows seal adaptor, a bellows, a spring, a static ring, a spring base, a movable ring component, a retainer shaft sleeve and a rubber inner lining ring, which is characterized in that a sealing part is arranged in the gap between the retainer shaft sleeve and the ceramic movable ring component; the left side of the sealing part is fixedly connected with the movable ring component in a vulcanization way, while the right side of the sealing part is adhered to the vertical face of the retainer shaft sleeve.
Description
Technical field
The utility model relates to a kind of automobile engine cooling water pump sealing configuration, belongs to motor car engine cooling component class.
Background technique
At present, the cooling waterpump sealing configuration that the Cherokee engine that Beijing Jeep Corporation Ltd. is introduced from U.S. Chrysler on the market is used, seal the ceramic ring of the main member of moving ring assembly as it, since in its outer ring on hoop guard ring, its body is exposed in the heat eliminating medium basically fully, so the frictional heat energy that produces in the engine operation is distributed soon and takes away.Just because of this structural feature is arranged, so since this sealing structure for water used 10 years at home, can guarantee to run 50,000 kilometers or laboratory test and not lose efficacy in 1000 hours, thereby not only use on the car, and be applied on large-scale 6105 diesel engines.
But along with the domestic Freeway Development of China, the speed of a motor vehicle of automobile is more and more faster; The domestic user also improves day by day to the reliability requirement of automobile simultaneously, and comparatively general proposition now runs 100,000 kilometers guarantee target.Under this high speed and high standard guarantee target, the weakness of this water-stop also has and appears, its greatest weakness is just also on moving ring assembly, because rubber ring is not with in its outer ring, so the static seal between rotating ring and the retainer axle sleeve is to be born by the elastometric lining circle that is installed between the two fully.In assembling during this sealing configuration, rubber ring be interference be contained between axle sleeve and the rotating ring endoporus, its magnitude of interference is about 0.3mm; So rubber is subjected to bigger compression.At the initial stage of using, sealing herein is very reliable; But in the condition of high temperature, rubber meeting deliquescing, the rubber of this deliquescing will produce wriggling as liquid, especially under the interference pressured state, will flow to two ends, and interference is diminished.On the other hand, under the long term high temperature working state, here the rubber ring of the fine matter of fourth also can wear out gradually, hardening.Because magnitude of interference diminishes, medium is hardening gradually again, so sealing reliability at this moment just worse and worse.
Therefore, how to improve above-mentioned watertight construction, make it adapt to new operating conditions, become a pressing problem.
Technology contents
The purpose of the present utility model: aim to provide a kind of follow-on automobile engine cooling water pump sealing configuration, improve its working life and reliability.
This automobile engine cooling water pump sealing configuration, form by corrugated header (1), bellows (2), spring (3), stationary ring (4), spring seat (5), moving ring assembly (6), retainer axle sleeve (7), elastometric lining circle (8) and guard ring (9), it is characterized in that in the gap between described moving ring assembly (6) inboard and the retainer axle sleeve (7) Sealing (10) being set.
Described Sealing (10) can be made of one with original elastometric lining circle (8).
Described Sealing (10) can be rubber mass or Bond.
Described Sealing (10) and moving ring assembly (6) and retainer axle sleeve (7) Bian Bicheng be bond state fixedly.
This automobile engine cooling water pump sealing configuration according to above method design, compare with the similar sealing structure for water that generally uses at present, owing between retainer axle sleeve end face, increase sealing at the moving ring assembly back side, make original single plane sealing change continuous biplane sealing into; And owing to adopt sulfuration and bonding method, solidity is connected to make itself and both sides sealing member be forever, even colloid is aging on the one hand, also can not influence sealing; On the other hand since herein rubber do not have interference, so can Yin Gaowen and produce wriggling and run off yet, cause seal failure.
Description of drawings
Accompanying drawing is the utility model structural representation.
Among the figure: 1. corrugated header 2. bellowss 3. springs 4. stationary rings 5. spring seats 6. moving ring assemblies 7. retainer axle sleeves 8. elastometric lining circles 9. guard rings 10. Sealings.
Embodiment
The sharp automobile engine cooling water pump sealing configuration of as shown in the figure this is a kind of improvement of existing U.S. Chrysler being used like product on Cherokee engine.They are made up of corrugated header (1), bellows (2), spring (3), stationary ring (4), spring seat (5), moving ring assembly (6), retainer axle sleeve (7), guard ring (9), it is characterized in that:, settle a Sealing (10) the about 0.5mm gap that originally is positioned between moving ring assembly (6) and the retainer axle sleeve (7); This Sealing (10) both can be an independently sealing component, also can make the extension of the rubber seal original with the bottom (8).The rubber seal that this one deck increases newly, be actually with former rubber pad be an integral body.In order to guarantee its sealing reliability, in actual fabrication, sealing part (10) by moving ring assembly this simultaneously be adopt vulcanization process with its with moving ring assembly (6) secure bond together, the side of close retainer axle sleeve (7) then uses the high-performance adhesive bonding.Owing to adopt above-mentioned two kinds of secure bond structures, therefore, even when the rubber parts inefficacy at moving ring assembly endoporus place, still can firmly check in this sealing defence line, road that planar section is set up, effectively prevent to leak.
Take above-mentioned improving one's methods just, thereby can improve the operational safety and the life-span of raw water pump sealing greatly.
Claims (4)
1, a kind of automobile engine cooling water pump sealing configuration, form by corrugated header (1), bellows (2), spring (3), stationary ring (4), spring seat (5), moving ring assembly (6), retainer axle sleeve (7), elastometric lining circle (8) and guard ring (9), it is characterized in that in the gap between described moving ring assembly (6) inboard and the retainer axle sleeve (7) Sealing (10) being set.
2, a kind of automobile engine cooling water pump sealing configuration according to claim 1 is characterized in that described Sealing (10) can be made of one with original elastometric lining circle (8).
3, a kind of automobile engine cooling water pump sealing configuration according to claim 1 is characterized in that described Sealing (10) can be rubber mass or Bond.
4, a kind of motor car engine according to claim 1, the cooling waterpump sealing configuration is characterized in that fixedly bond state of described Sealing (10) and moving ring assembly (6) and retainer axle sleeve (7) Bian Bicheng.
