Abstract
The utility model discloses a sealing device of a water pump bearing, comprising a sealing ring and a water-throwing ring, wherein the sealing ring is a triple-lip sealing ring and is in interference fit with a bearing connected with a shaft; a first lip and a second lip of the sealing ring are in interference fit with a mandrel; a third lip of the sealing ring is in interference fit with the water-throwing ring; and an inner hole of the water-throwing ring is in interference fit with the mandrel and rotates along with the rotation of the mandrel. In the utility model, the third lip additionally arranged on the sealing ring is in interference fit with the water-throwing ring to play roles of preventing dust and water; and when a cooling water pump of an engine leaks little water, water is thrown by the rotating water-throwing ring so as to prevent water from entering the inside of the bearing connected with the shaft, reduce the influence of the water leakage of the water pump on the bearing connected with the shaft, improve the reliability of the water pump bearing and prolong the service life of the water pump bearing.
Description
Technical field
The utility model relates to a kind of water pump bearing seal arrangement.
Background technique
In the recent period China stuffing box bearing quality testing result is shown that China's sealed bearing structure design problem is bigger according to national Technical Board, sealing effect is bad, and leakage fat phenomenon is more serious, and the user has strong complaints.By analysis, main cause is that the existing seal ring project organization of China is unreasonable, inner ring is not with seal groove, add accuracy of manufacturing not the plateau because of causing.
Motor just develops towards high-power, high efficiency direction as the core of automobile, therefore, water pump bearing has been proposed higher performance requirement, as has higher heat resistanceheat resistant performance, bigger bearing capacity and excellent sealing performance etc.The used Sealing major part of automobile engine cooling water pump shaft connecting bearing is single lip or lips mouth at present, and the characteristics of this type of Sealing are simple in structure, and cost is low, the efficiency of assembling height.If but this type of Sealing is used in impeller end, may there be certain risk, because the engine cooling water pump shaft connecting bearing requires long lifetime, high reliability, but can there be the situation of leaking under one situation of the water seal of engine cooling water pump, and the sealing of above-mentioned single lip seal of mentioning and lips mouth can't be operated in the environment of low amounts of water for a long time, can only be in a spot of steam the use of short time.
The model utility content
The purpose of this utility model provides a kind of water pump bearing seal arrangement, and is simple in structure, sealability height, reliability and the life-span that can effectively improve water pump shaft connecting bearings.
The technological scheme that realizes the utility model purpose is: a kind of water pump bearing seal arrangement, comprise seal ring and slinger ring, described seal ring is three lip seal circles, seal ring and shaft connecting bearing interference fit, first, second lip of seal ring and mandrel interference fit, the 3rd lip of seal ring and slinger ring interference fit, the endoporus of slinger ring and mandrel interference fit, and along with mandrel rotation and rotate.
The utlity model has positive effect: the 3rd lip and slinger ring interference fit that (1) seal ring of the present utility model increases, play sealing and dustproof and waterproof effect.
(2) endoporus of slinger ring of the present utility model and mandrel interference fit, and along with mandrel rotation and rotate, the slinger ring of rotation is thrown water away when engine cooling water pump leaks on a small quantity, stop water to enter shaft connecting bearing inside, reduce the influence of leakage from water pump, the reliability and the life-span of having improved water pump shaft connecting bearings to shaft connecting bearing.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and according to specific embodiment also in conjunction with the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is the structural representation of existing lips mouth sealing ring.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is the schematic representation of seal ring of the present utility model and slinger ring interference fit.
Label in the accompanying drawing is:
Embodiment
(embodiment 1)
See Fig. 1 to Fig. 3, present embodiment comprises, comprises seal ring 1, slinger ring 2, shaft connecting bearing 3 and mandrel 4.
The 3rd lip and slinger ring 2 interference fit that seal ring 1 increases play sealing and dustproof and waterproof effect.The endoporus of slinger ring 2 and mandrel 4 interference fit, and along with mandrel 4 rotation and rotate, the slinger ring 2 of rotation is thrown water away when engine cooling water pump leaks on a small quantity, stop water to enter shaft connecting bearing 3 inside, reduce the influence of leakage from water pump, the reliability and the life-span of having improved water pump shaft connecting bearings 3 to shaft connecting bearing 3.
Above-described specific embodiment; the purpose of this utility model, technological scheme and beneficial effect are further described; institute is understood that; the above only is a specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
Claims (1)
