The utility model is characterized in that the retainer (5) fixes the steel balls (4) between the outer ring (1) the inner ring (2) through the rivet (3); the flange coefficient Kd of the inner ring (2) is 0.40-0.45; the groove curvature factor of the outer ring (1) is 0.511-0.520; the groove curvature factor of the inner ring (2) is 0.520-0.530; the plate thickness of the retainer (5) is 0.45-0.55mm; the retainer (5) is a rivet waved retainer; the number of the steel balls (4) is not less than 20; and the diameter of the steel balls (4) is 3.5mm. The utility model ensures the deep groove ball bearing to satisfy the requirements of low noise, low swing and low friction, and prolongs the service life of the nonstandard bearing.
Description
Technical field
The utility model relates to a kind of deep groove ball bearing, relates in particular to the nonstandard deep groove ball bearing of a kind of thin-walled.
Background technique
Along with scientific and technological progress, no matter electronic product or engineering goods, automobile product, all light, lightweight, low noise gradually, cause bearing in relevant device also miniaturization gradually, lightweight, quietization, and the requirement to precision is more and more higher, for the low noise that obtains bearing, low friction torque, high rigidity, high reliability, good rotating accuracy, use rivet wave type shape design retainer.
In existing electric motor of automobile bearing, at a high speed or abnormal sound and frictional heating that under long-time the rotation, motor easily produces, sometimes can not meet the usage requirement of electric motor of automobile, bearing is seriously shortened working life, can not meet the demand of industry.
The model utility content
The purpose of this utility model is to provide a kind of thin-walled nonstandard deep groove ball bearing, has solved the phenomenon that the different sound of motor and frictional heating often occur existing bearing, the problem that working life is short.
For addressing the above problem, technical solution adopted in the utility model is:
A kind of nonstandard deep groove ball bearing, comprise outer ring (1), inner ring (2), rivet (3), steel ball (4), retainer (5) and lid (6), described retainer (5) is fixed on described steel ball (4) between described outer ring (1) and described inner ring (2) by described rivet (3), and the rib COEFFICIENT K d of described inner ring (2) is 0.40-0.45; The ditch coefficient of curvature of described outer ring (1) is got 0.511-0.520, and the ditch coefficient of curvature of described inner ring (2) is got 0.520-0.530; The thickness of slab of described retainer (5) is 0.45-0.55mm, and described retainer (5) is the rivet wave type retainer, and the number that arranges of described steel ball (4) is no less than 20, and the diameter of described steel ball (4) is 3.5mm.
Preferably, the rib COEFFICIENT K d of described inner ring is 0.423.
Preferably, the ditch coefficient of curvature of described outer ring (1) is 0.511, and the ditch coefficient of curvature of described inner ring (2) gets 0.52.
Preferably, the thickness of slab of described retainer (5) is 0.5mm.
Adopt the beneficial effect that technique scheme produces to be: the improvement of the design method by conventional bearing has met bearing low friction power, long-life usage requirement; Improvement by inside and outside circle ditch curvature, met the requirement of bearing ring and steel ball degree of adaptability; The improvement designed by retainer, met the in use requirement of retainer low noise, long lifetime and good lubrication of bearing.
The accompanying drawing explanation
Fig. 1 is the utility model structure sectional view;
Fig. 2 is retainer structural representation in Fig. 1.
Embodiment
Following the utility model is described in further detail:
As depicted in figs. 1 and 2:
The utility model provides a kind of nonstandard deep groove ball bearing, comprises outer ring 1, inner ring 2, rivet 3, steel ball 4, retainer 5 and lid 6, and retainer 5 is fixed on steel ball 4 between outer ring 1 and inner ring 2 by rivet 3, and the rib COEFFICIENT K d of inner ring 2 is 0.40-0.45; The ditch coefficient of curvature of outer ring 1 is got 0.511-0.520, and the ditch coefficient of curvature of inner ring 2 is got 0.520-0.530; The thickness of slab of retainer 5 is 0.45-0.55mm, and retainer 5 is the rivet wave type retainer, and the number that arranges of steel ball 4 is no less than 20, and the diameter of steel ball 4 is 3.5mm.
Adopt the beneficial effect that technique scheme produces to be: the improvement of the design method by conventional bearing has met bearing low friction power, long-life usage requirement; Improvement by inside and outside circle ditch curvature, met the requirement of bearing ring and steel ball degree of adaptability; The improvement designed by retainer, met the in use requirement of retainer low noise, long lifetime and good lubrication of bearing.
In an optimal way of the present utility model, the rib COEFFICIENT K d of inner ring is 0.423.
In another optimal way of the present utility model, the ditch coefficient of curvature of outer ring 1 is 0.511, and the ditch coefficient of curvature of inner ring 2 gets 0.52.
Particularly, the thickness of slab of retainer 5 is 0.5mm.
