Abstract
The invention provides a fan bearing seat. The fan bearing seat comprises a seat body, end covers located at two ends of the seat body, bearing chambers in inner sides of the end covers, bearings located in the bearing chambers as well as a through hole formed in an axial direction of the seat body and allowing a rotating shaft to penetrate through. The fan bearing seat is characterized in that a circular-ring-shaped water tank is arranged in the seat body, two ends of the water tank are fixed on the outer walls of the bearing chambers, a water inlet pipe is arranged at the top of the water tank, a water outlet pipe is arranged at the bottom of the water tank, an oil pipe is arranged at the top of the water tank, two ends of the oil pipe extend into the bearing chambers, and an oil injection pipe is arranged at the top of the oil pipe and extends upwards to the outer surface of the seat body. According to the fan bearing seat, cooling for the rotating shaft can be realized, the condition that the motor is burnt out due to the fact that the heat of a fan is transmitted to the motor through the rotating shaft is prevented, lubrication between the bearings and the rotating shaft is realized through the oil pipe arranged in the seat body, a large amount of heat generated through increase of friction is avoided, and the service life of the motor and the service life of the fan are guaranteed.
Description
Technical field
The invention belongs to field of ventilation equipment, be specifically related to bearing fan.
Background technique
Blower fan is mainly rotated by driven by motor rotatingshaft, the rotatingshaft the other end is connected with impeller, thus impeller is rotated, when impeller rotates for a long time, impeller bearing place can produce a large amount of heats, is passed to motor via rotatingshaft, owing to also can produce heat when motor itself works, therefore long-time running makes the heat of whole blower fan can not get dispersing, and easily makes motor or whole blower fan be burned.
Summary of the invention
For solving the problems of the technologies described above, the technical solution used in the present invention is: bearing fan, comprise pedestal, be positioned at the end cap at described pedestal two ends, bearing chamber inside described end cap, be positioned at the bearing of described bearing chamber, along described block body axis to the through hole passed for rotating shaft arranged, it is characterized in that: in described pedestal, be provided with ring water tank, described water tank two ends are fixed on described bearing chamber outer wall, water inlet pipe is provided with in described tank top, outlet pipe is provided with at described water tank bottom, oil pipe is provided with in described tank top, described oil pipe two ends extend in described bearing chamber, oil filler pipe is provided with at described oil pipe top, described oil filler pipe extends upwardly on described pedestal outer surface.
Further, between described end cap and described bearing chamber, ring sealing plug is provided with.
Further, between described water tank and described oil pipe, annular heat cotton is provided with.
Further, described water inlet pipe extends upwardly to described pedestal upper surface from described tank top, and described discrepancy pipe extends downward described pedestal lower surface from described water tank bottom.
Further, described oil pipe two ends are provided with the arm perpendicular to described oil pipe, and the described arm the other end extends in described bearing chamber.
Further, described oil pipe and described arm are one-body molded setting.
Further, the equal diameters of described oil pipe and described arm.
The advantage that the present invention has and good effect are:
1, the present invention can realize the cooling to rotatingshaft, avoids the heat of blower fan be passed to motor by rotatingshaft and burn out motor, ensure that the working life of motor and blower fan.
2, by arranging the lubrication that oil pipe realizes between bearing and rotating shaft in pedestal, avoiding because friction becomes large and producing a large amount of heats, ensure that the working life of motor and blower fan.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.
As shown in Figure 1, the invention provides a kind of bearing fan, comprise pedestal 1, be positioned at the end cap 2 at described pedestal 1 two ends, bearing chamber 4 inside described end cap 2, be positioned at the bearing 5 of described bearing chamber 4, along the through hole passed for rotating shaft that described pedestal 1 is axially arranged, it is characterized in that: in described pedestal 1, be provided with ring water tank 6, described water tank 6 two ends are fixed on described bearing chamber 4 outer wall, water inlet pipe 7 is provided with at described water tank 6 top, outlet pipe 71 is provided with bottom described water tank 6, oil pipe 9 is provided with at described water tank 6 top, described oil pipe 9 two ends extend in described bearing chamber 4, oil filler pipe 10 is provided with at described oil pipe 9 top, described oil filler pipe 10 extends upwardly on described pedestal 1 outer surface.
Further, between described end cap 2 and described bearing chamber 4, ring sealing plug 3 is provided with.
Further, between described water tank 6 and described oil pipe 9, be provided with annular heat cotton 8, the setting of heat insulation foam 8 is in order to avoid the heat outside pedestal 1 is passed to pedestal 1 inside, increases inner heat radiation difficulty.
Further, described water inlet pipe 7 extends upwardly to described pedestal 1 upper surface from described water tank 6 top, and described discrepancy pipe extends downward described pedestal 1 lower surface bottom described water tank 6, is convenient to carry out continuing to change to cooling water, ensures radiating effect.
Further, described oil pipe 9 two ends are provided with the arm 91 perpendicular to described oil pipe 9, and described arm 91 the other end extends in described bearing chamber 4.
Further, described oil pipe 9 and described arm 91 are in one-body molded setting.
Further, the equal diameters of described oil pipe 9 and described arm 91.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
