Embodiment
A kind of embodiment of the 1-4 descriptions present invention below in conjunction with the accompanying drawings.
Following embodiment facilitates a better understanding of the present invention, but does not limit the present invention.It is involved in following embodiments
Fan bearing holder structure, be conventional blower bearing block structure unless otherwise specified.
Bearing fan, has base 1 and bearing block housing, and the bearing block housing both ends have the axle of installation bearing 3
Hold box 2, to realize saving to bearing block injection flow, the bearing box 2 have infiltration bearing 3 bottom oil storage tank 4 (such as Fig. 1,
Shown in Fig. 4), separately design out oil storage tank 4 in the bearings at both ends box of spindle rotation axis 10, during work, make the lower contacts of bearing 3 in profit
Below lubricating oil face, in running at high speed, take up lubricating oil and implement lubrication；To realize to bearing 3 from inner ring, to outer ring or even main shaft
The comprehensive abundant Water-cooling circulating of rotary shaft 10 and lubricating oil, the outer ring of 2 interior edge bearing of bearing box 3 are radially provided with bearing
Outer ring water composite cooling pipe 5, the bearing box 2 is interior to be connected with bearing outer ring water composite cooling pipe 5 provided with the bearing side arranged along the inner ring of bearing 3
Face water cooling ring 6 (as shown in Figure 1, Figure 2, Figure 3 shows), connects along rotary shaft 10 with bearing side water cooling ring 6 and is provided with axially below
The axial water-cooled contacted with lubricating oil but connecting tube 7 (referring to Fig. 3).
In above-mentioned technical proposal, to realize near-end oiling, unnecessary filling loss is reduced, and conveniently oil level is supervised
Depending on as optimal technical scheme, the bearing block housing central section is provided with pouring orifice 8, the lower section of pouring orifice 8 close to oil storage tank 4
Oil level Judas-hole 9 are provided with positioned at bearing block housing sidewall.(referring to Fig. 4)
In above-mentioned technical proposal, to coordinate external water circulating apparatus to realize, the near-end water close to bearing inner race conveys, and is beneficial to
The efficient water circulation of water-cooling system, the bearing block housing side connect provided with the inner ring of face bearing 3 with bearing side water cooling ring 6
Logical water inlet 601 and delivery port 602.(referring to Fig. 2)
It can be seen that the water-cooling circulating system of this programme bearing block is compared with the water cooling oil immersed type that Authorization Notice No. is CN202900742U
Fan Bearing Box not only includes bearing outer ring Water-cooling circulating and axial water-cooled circulates, in addition to bearing inner race Water-cooling circulating, not only
Water-cooled cooling can be realized to bearing outer ring, while reinforcement water-cooled cooling effect is especially played to bearing inner race, passes through bearing
The arrangement of side water cooling ring 6, the water shielding effect of isolation shaft end thermal source, more simple bearing outer ring water are played to a certain extent
For SAPMAC method, water-cooled cooling effect of the bearing fan integrally including the inside and outside circle of bearing including common can be greatly reinforced.Installation
In use, by connecting water-supply-pipe, circulating pump and cyclic water tank, blower fan can be made to realize comprehensive water circulation in running at high speed
Cooling, make bearing operation temperature begin eventually protect hold at≤70 DEG C, ensure bearing run well and it is indeformable, be more beneficial for extend blower fan
The service life of bearing；In addition, the structure that bearing box 2 and the oil storage tank 4 of infiltration bearing 3 bottom are combined into one, more individually sets up
Oil lubricating station mode, considerably reduces oil reserve, reduces operating cost, and filling lubricating oil is than original by few 60%, use
The mode of bottom infiltration is realized to bearing to be lubricated, and bearing touch lubrication pasta is kept constant, has still been reached sufficient lubrication
Purpose, meet that bearing rotates the needs of sufficient lubrication, the market demand of composite energy-saving low cost operation；In addition, the present invention is axially
The position of water cooling connecting tube 7, has not only connected the water route of bearings at both ends side water cooling ring 6, is but connected by axial water-cooled
Contact of the pipe 7 with lubricating oil, in addition to realizing cooling except the inner ring of bearing 3, outer ring and spindle rotation axis 4, also achieve to lubrication
Oily is sufficiently cool, and double cooling effects of bearing and lubricating oil significantly increase, Water-cooling circulating significant effect, is relatively beneficial to extend wind
Machine bearing service life, cooperate with and directly design the collective effect of oil storage tank 4 in the bearings at both ends box 2 of spindle rotation axis 10, pass through bearing 3
Bottom is infiltrated on lubrication pasta, in running at high speed, take up lubricating oil implement lubrication mode cool down, save, lubricant effect it is all
It is good.
Above-described embodiment, simply presently preferred embodiments of the present invention, is not used for limiting the scope of the present invention, therefore all with this
The equivalence changes that content described in invention claim is done, it all should be included within scope of the invention as claimed.
