Abstract
The utility model discloses a bearing seat of an air cooling fan. The bearing seat comprises a bearing seat body and a bearing cavity, wherein the bearing cavity is arranged on the bearing seat body, an oil injecting hole is arranged in the bearing cavity along the radial direction to edges of the bearing seat body, two rows of aligning roller bearings are installed in the bearing cavity, an annular lubricating grease slot is arranged on the periphery of two rows of aligning roller bearings, the oil injecting hole is flush with the annular lubricating grease slot, a lubricating grease hole is arranged on the annular lubricating grease slot, and the lubricating grease is communicated with a bearing roller located in a bearing. The fan bearing can be refueled on line, the bearing lubrication condition is modified, the service life of the bearing is improved, the potential hazard caused by long-term operation of the device is removed, the maintenance working quantity and the maintenance cost are reduced and the device operation cost is reduced.
Description
Technical field
The utility model relates to a kind of bearing support, relates in particular to a kind of air cooling blower fan bearing support.
Background technique
Air cooling blower fan belongs to cool exchanging equipment, generally is installed in the overhead high-altitude of 20～40m, and can Main Function be to take away the heat that the production process medium produces, its work throughput of direct relation auto levelizer and quality of product.Air cooling blower fan is by motoring, and by " V " type belt transmission, motor is positioned at the below of air cooling blower fan, and the ventilation and heat condition is better.And the blower fan rotary component is positioned at air cooling blower fan radiating fin inside, and working environment is relatively disliked slightly, and ambient temperature is higher, generally between 45 ℃～75 ℃, internal environment is relatively poor, and dust is more, when opening spray system and lower the temperature to summer especially, the blower fan internal environment is more disliked slightly.The air cooling blower fan bearing petrol starvation occurred for preventing bearing before first the installation, the maintainer artificially reaches bearing support up and down to be coated with full lubricating grease in the two row bearing rollers.But through the operation of one-phase, some people is to be coated with full lubricating grease slow consumption to fall, and coking appears in another part lubricating grease under the rugged environment such as high temperature, cause the lubricating grease deterioration failure.In a single day lubricating grease lost efficacy, and bearing will lose the lubricated and protective action of lubricating grease, and the bearing dry friction causes bearing to damage in advance, and induction-motor load increases.Because fan bearing is positioned at fan radiating fin inside, need to be to the medium amount of falling, cooling during maintenance, the maintainer need to enter blower fan inside and construct, and the device maintenance difficulty is large, affects device and normally produces.
For timely supplemental lubrication fat, just need to use oil gun to add by the lubricating grease fuel filler neck on the bearing support, lubricating grease enters in the bearing support by the lubricating grease fuel filler neck, but because there is the direct UNICOM of a grease trough bearing gland existing bearing support inboard, therefore, when using the grease gun grease up, lubricating grease is that this oil groove has directly entered the bearing top through nearest path under pressure, and can't enter on the bearing roller by the oil groove on the bearing and oilhole, cause bearing to damage because of oil starvation.
The model utility content
Based on above-mentioned technical problem, the utility model provides a kind of air cooling blower fan bearing support.
Its technical solution is:
A kind of air cooling blower fan bearing support, comprise bearing seat and bearing bore, described bearing bore is arranged on the bearing seat, described bearing bore radially is provided with oil hole to the edge of bearing seat, the double-row self-aligning roller bearing is installed in bearing bore, is provided with annular grease trough in the outer periphery of double-row self-aligning roller bearing, oil hole and annular grease trough are on the same level face, offer the lubricating grease hole at annular grease trough, the lubricating grease hole is connected with the bearing roller that is positioned at bearing inside.
Further, the number in above-mentioned lubricating grease hole arranges 4, and is evenly distributed on the annular grease trough.
Further, after above-mentioned double-row self-aligning roller bearing was installed in the bearing bore, described oil hole was aimed at one of them lubricating grease hole.
Further, attacked screw thread on the inwall of described oil hole.
Useful technique effect of the present utility model is:
The utility model has realized that fan bearing refuels online, has improved bearing lubrication condition, has improved bearing working life, has eliminated the hidden danger that the equipment long-term operation exists, and has reduced simultaneously maintenance workload and maintenance cost, has reduced equipment operating cost.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment:
Fig. 1 is the structural principle schematic representation of air cooling blower fan bearing support;
Fig. 2 is the sectional view of Fig. 1;
Fig. 3 is the structural representation of double-row self-aligning roller bearing.
Among the figure: 1-bearing seat, 2-bearing bore, 3-oil hole, 4-double-row self-aligning roller bearing, the above-listed bearing of 401-, the following bearing of 402-, 403-bearing roller, 5-annular grease trough, 6-lubricating grease hole, 7-fixed hole.
Embodiment
By reference to the accompanying drawings, a kind of air cooling blower fan bearing support comprises bearing seat 1 and bearing bore 2, and bearing bore 2 is arranged on the bearing seat 1, radially is provided with oil hole 3 to the edge of bearing seat 1 at bearing bore 2.The internal diameter of oil hole 3 is 14.2mm, has attacked the M16*10mm screw thread at the inwall of oil hole 3, is convenient to link to each other with fuel filler neck on the nozzle.At bearing bore 2 interior installation double-row self-aligning roller bearings 4, double-row self-aligning roller bearing 4 comprises above-listed bearing 401 and following bearing 402, be provided with annular grease trough 5 in the outer periphery of double-row self-aligning roller bearing 4, oil hole 3 is on the same level face with annular grease trough 5.Offer lubricating grease hole 6 at annular grease trough 5, lubricating grease hole 6 is connected with the bearing roller 403 that is positioned at double-row self-aligning roller bearing 4 inside.The number in above-mentioned lubricating grease hole 6 arranges 4, and is evenly distributed on the annular grease trough 5.When double-row self-aligning roller bearing 4 be installed in bearing bore 2 interior after, described oil hole 3 is aimed at one of them lubricating grease hole 6.
The below describes working procedure of the present utility model:
When the bearing oil starvation, the fuel filler neck on the nozzle is linked to each other with oil hole, lubricating grease advances along annular grease trough under pressure, and arrives on the bearing roller by the lubricating grease hole on the bearing, guarantees that upper and lower two row bearings have grease lubrication.The utility model is not established the lubricating grease oil groove that is connected between bearing support and bearing gland, if original air cooling blower fan is transformed, the lubricating grease oil groove welding that original bearing support need to be connected with bearing gland fills, and prevents that lubricating grease from directly entering bearing gland by this oil groove.
Need to prove that under the instruction of this specification, any equivalents that those skilled in the art have done, or obvious variant all should be within protection domains of the present utility model.
