In the prior art, technician have no idea to carry out external world's cooling to bearing, because its high rotating speed, due to centrifugal action, the lubricant oil of cooling just touch at all less than ball just by wind to preventing, you also can realize with high pressure oil certainly, the effect of this way is not good yet, have a large amount of oil to be wasted, and will high-tension apparatus be added, also create a no small expense.This patent is then different, in the side of bearing, has added the quite simple blower cover of a structure, in the bearing process of High Rotation Speed, has utilized the effect of blower cover, wind is produced the flowing to a blower cover direction, produce at the other end of bearing the wind attracted; In such a case, have the side oiling attracting wind, just can not produce centrifugal, be centripetal on the contrary; That can gently anticipate is injected into oil in the middle of ball.
Be improved further technique scheme, the rotating blading on described inner cover inwall and horizontal line are in angle of 45 degrees; Inner cover and rotating blading one-body molded.By the design of this 45 degree of angles, make the eolian Whirl deposite tank of discharging, thus add the air output of huge another side, due between air-out oil-feed across ball, so opposite side only can strengthen air output, and eddy flow can not be produced, any trouble can not be caused to oiling.
Technique scheme is improved further, in another side of bearing, the opposite of blower cover; The sidewall of inner ring is provided with and draws oily balance ring, and described drawing in oily balance ring is provided with several oil grooves, and oil groove is connected with the track of inner ring, and intercommunicating pore in " U " shape, and reduces to track export gradually by drawing oily balance ring.Described " U " shape intercommunicating pore is the outlet of Liang Ge road, is connected to the both sides of ball respectively.
This programme solves two large problems, and one is the equilibrium problem after installing blower cover additional, and second is solve oiling uniformity problem; Drawing oily balance ring by installing additional, both sides weight can be balanced, on the other hand, be designed to channel-shaped, give ball by through hole more uniformly by oil.
