Description
Technical field
The utility model relates to a kind of seal arrangement, especially relates to a kind of device that keeps the fan bearing sealing.
Background technique
Centrifugal blower will guarantee that bearing has good sealing, the method adopted at present is to use sealing rubber pad at the bearing place, and outside need be filled with certain air and make external pressure be greater than internal pressure, thereby assurance bearing seal, because the method need to be filled with air, operating cost is higher, and after long operational time, sealing rubber pad is easily aging, changes inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of seal arrangement of fan bearing, this apparatus structure compactness, and cost is low, installation, convenient disassembly, and good sealing effect.
The utility model is achieved by the following technical programs:
A kind of seal arrangement of fan bearing, be arranged on the fan shaft between blower fan flange seat and fan bearing, comprises back-up ring, spring, copper ring, and back-up ring is arranged on the cylindrical of fan shaft and fixes by Cock screw; Copper ring is arranged on the cylindrical of fan shaft, and one end contacts with an end face of blower fan flange seat, and this end face is provided with the oil storage ring, and the oil storage ring is provided with several oil storage holes, and the copper ring inner ring is provided with several seal rings; Be provided with a spring between back-up ring and copper ring, spring is arranged on the cylindrical of fan shaft.
The purpose of this utility model can also further realize by following technical measures.
The seal arrangement of aforesaid a kind of fan bearing, spring is all the time in compressive state.
The seal arrangement of aforesaid a kind of fan bearing, be provided with paste lubricating grease in oil storage ring and oil storage hole.
Copper ring of the present utility model and fan shaft rotate simultaneously, and the copper ring inner ring is provided with seal ring and is sealed, good seal performance; And, owing to injecting paste lubricating grease in oil storage ring and oil storage hole, not only the surface of contact between Castor Oil but also salable copper ring and blower fan flange seat, can reduce the wearing and tearing of copper ring, long service life, and can further guarantee sealing.
Advantage and disadvantage of the present utility model, will be for illustration and explanation by the non-limitative illustration of following preferred embodiment, and these embodiments, only provide as an example with reference to accompanying drawing.
The accompanying drawing explanation
Fig. 1 is plan view of the present utility model.
