Abstract
The utility model discloses a kind of elastic rolling bearing with waveform paillon foil.Comprise the second bearing outer ring, bearing inner race, rolling element and retainer; One circle waveform paillon foil is set between the second bearing outer ring external cylindrical surface groove and clutch shaft bearing outer ring inner cylindrical surface groove.When under load, the distortion of paillon foil can reduce the Max.contact stress between rolling element and inside and outside raceway, reduce juxtaposition metamorphose, alleviate lubricant film under case of heavy load and be squeezed and break and the sharply increasing of frictional force, avoid the further temperature rise because insufficient lubrication causes; When bearing heating causes part to produce thermal expansion, certain yielding effect is played in the distortion of paillon foil, and the size for other parts is flexible has abdicated space, reduces distortion and the internal stress of two bearing outer rings, bearing inner race and rolling elements.The distortion yielding effect of paillon foil effectively can also alleviate the impact of the polygon effect shaft vibration of rolling element.
Description
Technical field
The utility model relates to a kind of rolling bearing, especially a kind of elastic rolling bearing with waveform paillon foil.
Background technique
When rolling bearing works under load effect, will there is resiliently deformable in rolling element and Internal and external cycle, make to generate elastohydrodynamic lubrication oil film in bearing.The main integrated distribution of contact stress is rolling element and Internal and external cycle contact area in movement process, and contact stress has important impact to the contact fatigue of bearing and wearing and tearing, decides the reliable life of bearing to a great extent.Be operated in the rolling bearing under fully loaded transportation condition, its rolling element is in high pressure conditions for a long time, and between rolling element and raceway, the excessive lubricant film that causes of contact stress breaks, and makes that frictional force is excessive so that bearing is stuck.The excessive bearing that also can cause of the distortion of rolling element cannot rotate.The contact condition optimizing rolling element and inside and outside raceway for the lubricating condition improving rolling bearing with to improve rolling bearing life significant.
Model utility content
The purpose of this utility model is to provide a kind of elastic rolling bearing with waveform paillon foil, elastic rolling bearing can reduce the juxtaposition metamorphose between rolling element and inside and outside raceway effectively, reduce Max.contact stress and optimize distribution of contact, reducing friction torque and the temperature rise of bearing.
The technical solution adopted in the utility model is:
The utility model comprises the second bearing outer ring, bearing inner race, rolling element and retainer; Clutch shaft bearing outer ring coaxial sleeve, outside the second bearing outer ring, arranges a circle waveform paillon foil between the second bearing outer ring external cylindrical surface groove and clutch shaft bearing outer ring inner cylindrical surface groove.
Described waveform paillon foil is the paillon foil that circular plastic metal material is stamped to form.
The beneficial effect that the utility model has is:
1, when under load, paillon foil more easily deforms, thus can reduce the Max.contact stress between rolling element and inside and outside raceway, reduces juxtaposition metamorphose, makes the oil slick thickness of friction in bearings pair larger, is conducive to the lubrication of bearing.Lubricant film under case of heavy load can also be alleviated be squeezed and break and the sharply increasing of frictional force, avoid the further temperature rise because insufficient lubrication causes.
2, when heating in bearing working process causes part to produce thermal expansion, certain yielding effect is played in the distortion of paillon foil, size for other parts is flexible has abdicated space, because this reducing distortion and the internal stress of two bearing outer rings, bearing inner race and rolling elements.The distortion yielding effect of paillon foil can also reduce the change of the play size caused because of the thermal distortion of Internal and external cycle effectively, and can alleviate the impact of the polygon effect shaft vibration of rolling element.
3, the resiliently deformable of paillon foil can play buffering shock-absorbing effect, can not only alleviate impact heavy duty and impulsive load to the destruction of bearing parts, the impact of impulsive load on rotor system stability can also be reduced.

Fig. 2 is conventional rolling bearing Internal and external cycle relative displacement after bearing radial load and the stressed schematic diagram of each rolling element.
Fig. 3 is the utility model rolling bearing Internal and external cycle relative displacement after bearing radial load and the stressed schematic diagram of each rolling element.
In figure: 1, clutch shaft bearing outer ring, 2, waveform paillon foil, the 3, second bearing outer ring, 4, retainer, 5, rolling element, 6, bearing inner race.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1, the utility model comprises the second bearing outer ring 3, bearing inner race 6, rolling element 5 and retainer 4; Clutch shaft bearing outer ring 1 coaxial sleeve, outside the second bearing outer ring 3, arranges a circle waveform paillon foil 2 between the second bearing outer ring 3 external cylindrical surface groove and clutch shaft bearing outer ring 1 inner cylindrical surface groove.
Described waveform paillon foil 2 is the paillon foil that circular plastic metal material is stamped to form.Waveform paillon foil 2 is clamped between clutch shaft bearing outer ring 1 and the second bearing outer ring 3, and the oil slick thickness of friction in bearings pair during waveform foil deformation is larger, is conducive to the lubrication of bearing.
Internal and external cycle relative displacement after radial load and each rolling element stressing conditions and the utility model rolling bearing are born to conventional rolling bearing and bears the Internal and external cycle relative displacement after radial load and each rolling element stressing conditions carries out com-parison and analysis.
As shown in Figure 2, after conventional rolling bearing bears radial load R, inner ring moves a certain distance along load R direction, upper half-turn rolling element not bearing load, and lower branch rolling element bears the load varied in size, and the load of bearing is larger, and the amount of deformation of rolling element is larger.
As shown in Figure 3, after elastic rolling bearing bears radial load R, waveform paillon foil can deform, distortion due to paillon foil assume responsibility for certain radial force, the extruding force caused by radial load R suffered by rolling element can reduce, the amount of deformation of rolling element is also corresponding to be reduced, the relative displacement of Internal and external cycle also than little when there is no a waveform paillon foil, each rolling element stressed also more even.
It is important to note that the described radial distribution of contact situation with the elastic rolling bearing of waveform paillon foil obviously will be better than conventional rolling bearing.And this has just embodied superiority of the present utility model.
Above-mentioned embodiment is used for explaining and the utility model is described; instead of the utility model is limited; in the protection domain of spirit of the present utility model and claim, any amendment make the utility model and change, all fall into protection domain of the present utility model.
