Abstract
The utility model discloses a rolling bearing with particle lubrication. The rolling bearing comprises a bearing outer ring, a bearing inner ring, a holding frame and a rolling body, wherein magnetic micro lubricating particles are adsorbed on the surfaces of the rolling body, the holding frame, and inner and outer runners; sealing rings are respectively arranged at two sides of the rolling bearing outside the magnetic micro lubricating particles; and the rolling body, the holding frame, and inner and outer runners are contacted through the magnetic micro lubricating particles. After the bearing operates, the magnetic micro lubricating particles adsorbed in the contact region can realize in-situ lubrication, which is favorable for reducing friction force and contact abrasion between the runners and the rolling body, and improving lubricating performance of the bearing; the lubricating particles are solid, thereby being not easy to leak and favorable for sealing, and lubricating working performance of the bearing can be kept stable for a long period; and the rolling bearing is favorable for simplifying maintenance process of the bearing, and reducing maintenance cost of the bearing.
Description
Technical field
The utility model relates to a kind of rolling bearing, relates in particular to a kind of rolling bearing with particle lubrication.
Background technique
Rolling bearing converts the axle of running and the sliding friction between axle bed to rolling friction by rolling element, effectively reduces friction, has improved running efficiency and the working life of axle.Rolling element is the core parts in rolling bearing, due to its existence, rolling friction is arranged just between relative motion surface.Bearing is lubricated the working life that can improve bearing, still, due to the motion of rolling element self, the oiling agent in bearing is not equally distributed usually; In addition, because the rolling of rolling element with the bearing internal external raceway contacts, oiling agent is difficult to the contact area is kept permanently effective lubricated under squeezing action.There are the problem of leaking in general oil lubrication and grease lubrication.
A weight is placed on the spheric granules heap, the mutual rolling between spheric granules, and surface friction drag is very little, under the Action of Gravity Field of weight, the bottom of falling the spheric granules heap that weight can be very fast.
Based on above-mentioned background, under the prerequisite that does not affect bearing load carrying capacity, if the contact area that is adsorbed on bearing that the greasing substance in bearing can be even, stable just can effectively improve greasy property, thereby improve the working life of bearing.If greasing substance can reduce the generation that even addresses the leakage concern by stabilized seal in bearing, thus the working life of improving oiling agent, the maintenance procedures of simplification bearing, the maintenance cost of reduction bearing.
Summary of the invention
The purpose of this utility model is to provide a kind of rolling bearing with particle lubrication, the small lubricated granules of magnetic can be stablized the surface that is adsorbed on rolling element and inside and outside raceway, the contact area is lubricated, and is difficult for leaking, improved the lubricated service behaviour of bearing.
The technological scheme that the utility model adopts is:
The utility model comprises bearing outer ring, bearing inner race, retainer and rolling element.The small lubricated granules of magnetic is adsorbed on rolling element, retainer and inside and outside raceway face, and the small lubricated granules of magnetic outer rolling bearing both sides are respectively equipped with seal ring, contact by the small lubricated granules of magnetic between rolling element, retainer and inside and outside raceway.
The small lubricated granules of described magnetic is spherical, and magnetic small lubricated granules sphere diameter is the rolling bearing radial internal clearance
The beneficial effect that the utlity model has is:
1) the small lubricated granules of magnetic is stable is adsorbed on rolling element, retainer and inside and outside raceway face, and in the bearing operation process, the small lubricated granules of magnetic that is adsorbed on the contact area realizes that original position is lubricated, has reduced contact wear, is conducive to improve the working life of bearing.
2) rolling between the small lubricated granules of dependence magnetic, reduced the slip between rolling element and bearing inner race raceway, outer ring raceway.
3) be difficult for leaking after the small lubricated granules sealing of magnetic, the lubricated service behaviour of bearing can maintain a long-term stability, and is conducive to simplify the maintenance procedures of bearing, reduces the maintenance cost of bearing.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and case study on implementation.
As shown in Figure 1 and Figure 2, the utility model comprises in bearing outer ring 1, bearing inner race 6, retainer 4 and rolling element 2(case study on implementation being deep groove ball bearing).Have the small lubricated granules 3 of magnetic and be adsorbed on rolling element 2, retainer 4 and inside and outside raceway face, the outer rolling ball bearing both sides of the small lubricated granules of magnetic 3 are respectively equipped with seal ring 5, contact by the small lubricated granules 3 of magnetic between rolling element 2, retainer 4 and inside and outside raceway.
The small lubricated granules 3 of described magnetic is spherical, and material is barium ferrite, and magnetic small lubricated granules 3 sphere diameters are the rolling bearing radial internal clearance
Rely on the rolling of 3 of the small lubricated granules of magnetic, reduced the slip of 1 of rolling element 2 and bearing inner race 6, bearing outer ring.Magnetic miniature spherical particle 3 is sealed in it in bearing bore by the seal ring 5 of bearing both sides.
Above-mentioned embodiment is used for the utility model of explaining; rather than the utility model is limited; in the protection domain of spirit of the present utility model and claim, any modification and change to the utility model is made all fall into protection domain of the present utility model.
