Description
Technical field
The invention belongs to technical field of bearings, be specifically related to the dustproof cooling device of a kind of rolling bearing.
Background technique
Along with the continuous development of industrial technology, the requirement that improves rotating speed and increase the service life has been proposed also rotating machinery.Rolling bearing is as the critical component of rotating machinery, and can its performance and running state determining rotating machinery move reposefully.Meanwhile, rolling bearing also is the easily damaged parts of rotating machinery, and according to statistics, the fault of rotating machinery has 30% to be that rolling bearing causes approximately.Therefore, the operational reliability of raising rolling bearing is to improve the key of rotating machinery performance.
In the running, have two principal elements can cause rolling bearing to break down or inefficacy in advance: bearing running hot, lubricant oil are subjected to airborne impurity particle and pollute.Rotating machinery is under the high speed operation state, because friction and the shearing of lubricant oil viscosity take place between each element of rolling bearing, the inner heat of giving birth to of bearing raises fast, if these heats can not be discharged at short notice, just can be in the rolling bearing accumulated inside, thereby cause the rolling bearing inside temperature to raise unusually, and will cause that lubricant viscosity descends, bearing load carrying capacity weakens.Simultaneously, the bearing inside temperature is too high also can to cause bearing surface of contact material temper softening, thereby causes the bearing premature fatigue to lose efficacy.Temperature is too high more serious also can be caused the bearing gummed and kills.And the oiling agent of not enough cleaning will make the vibration of rolling bearing and noise sharply increase.The solid impurity that is contained in the lubricant oil can influence the formation of lubricating film between each element of bearing, hard impurity also may heavy damage the lubricant film of bearing, thereby change the Lubrication of Rolling Contact Bearing state, cause the forfeiture of the bad even greasy property of bearing lubrication.
Prevent that so how airborne solid particle from entering bearing and reducing bearing temperature is two key issues that improve the rolling bearing operational reliability always.And the solution of these two problems also exists the relation that checks and balance, and some Production of bearing manufacturers are that bearing has been taked seal approach at present, prevents that by in the bearing outside dust cover being installed airborne solid particle from entering bearing.But seal approach has also influenced the cross-ventilation heat radiation of bearing in low-grade dust, this can cause the further raising of bearing temperature undoubtedly.At present, the active heat removal technology of bearing is normally driven cooling bath in the Bearing Installation seat, introduces the cooling liquid cooling that circulates therein.But there are a series of problems such as complex structure, processing difficulties, cost of production height in this method.
Summary of the invention
In order to overcome the deficiency that above-mentioned prior art exists, the object of the present invention is to provide a kind of rolling bearing cooling device that prevents dust, can provide effectively dustproof and cooling function for rolling bearing, thereby improve the running state of rolling bearing and increase the service life, and make, assemble and install simply, easy to use.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of rolling bearing cooling device that prevents dust, comprise dust cover 1, described dust cover 1 has center hole 6, rotating shaft 5 external diameters that these center hole 6 apertures are supported greater than corresponding rolling bearing 3, described dust cover 1 passes rotating shaft 5 by its center hole 6 and is fixed on a side of the bearing support 2 of corresponding rolling bearing 3, dust cover 1 has the through slot 8 that connects along double side, the left surface of this through slot 8 is covered by filter screen 7, is provided with fan 4 and pass rotating shaft 5 in the side of the close rolling bearing 3 of opposite side of bearing support 2.
Connect by tensioner connecting sleeve 10 between described fan 4 and the rotating shaft 5.
Through slot 8 quantity of described dust cover 1 are more than two and the size shape unanimity, and the side of through slot 8 is uniformly distributed in the side of dust cover 1.
The right part of described through slot is a projection 9.
Described center hole 6 interior circumferentially has 2-3 ring packing groove 11.
The rolling bearing of the present invention cooling device that prevents dust, mainly form, can provide effectively dustproof and cooling function, thereby improve the running state of rolling bearing and increase the service life for rolling bearing by dust cover 1 and fan 4, and make, assemble and install simply, easy to use.

Embodiment
The present invention will be described in more detail below in conjunction with accompanying drawing.
As shown in drawings, the rolling bearing cooling device that prevents dust, comprise dust cover 1, described dust cover 1 has center hole 6, these center hole 6 apertures are slightly larger than rotating shaft 5 external diameters that corresponding rolling bearing 3 supports, described dust cover 1 passes rotating shaft 5 by its center hole 6 and is fixed on a side of the bearing support 2 of corresponding rolling bearing 3, dust cover 1 has the through slot 8 that connects along double side, the left surface of this through slot 8 is covered by filter screen 7, is provided with fan 4 and pass rotating shaft 5 in the side of the close rolling bearing 3 of opposite side of bearing support 2.Connect by tensioner connecting sleeve 10 between described fan 4 and the rotating shaft 5.Through slot 8 quantity of described dust cover 1 are more than two and the size shape unanimity, and the side of through slot 8 is uniformly distributed in the side of dust cover 1.The right part of described through slot is a projection 9.Described center hole 6 interior circumferentially has 2-3 ring packing groove 11.
Working principle of the present invention is: when rotating shaft 5 rotations drive fan 4 work, make rolling bearing 3 be lower than the air pressure of rolling bearing 3 opposite sides near near the air pressure fan 4 one sides, thereby produce the axial flow of the rolling bearing 3 of flowing through, and then the heat that rolling bearing 3 produces in running taken away, play effect for the rolling bearing cooling, filter screen 7 on the dust cover 1 can shield the granule foreign in the axial flow outside rolling bearing 3 simultaneously, thereby prevents that airborne granule foreign from entering the rolling bearing 3 inner lubricant pollutions that cause rolling bearing 3 inside with axial flow.
The rolling bearing of the present invention cooling device that prevents dust, mainly form, can provide effectively dustproof and cooling function, thereby improve the running state of rolling bearing 3 and increase the service life for rolling bearing 3 by dust cover 1 and fan 4, and make, assemble and install simply, easy to use.Connect by tensioner connecting sleeve 10 between described fan 4 and the rotating shaft 5, it is more simple that such structure makes fan 4 install.Through slot 8 quantity of described dust cover 1 are more than two and the size shape unanimity, and the side of through slot 8 is uniformly distributed in the side of dust cover 1, and such structure makes that the axial flow that produces the rolling bearing 3 of flowing through is more stable.The right part of described through slot 8 is a projection 9, and such structure makes that fixedly dust cover 1 is more convenient.Described center hole 6 interior circumferentially has 2-3 ring packing groove 11, such structure realizes gas seal by the labyrinth gap that forms between rotating shaft 5 and the center hole 6, can prevent that more airborne solid particle from entering rolling bearing 3 inside by the gap between center hole 6 and the rotating shaft 5.
