Abstract
The invention relates to a retaining ring for a bearing, which is a notched circular and flaky structural member. On both sides of the midpoint of a circle, the outer side of the retaining ring is symmetrically provided with two identical grooves; on both sides of the midpoint of the circle, the inner side of the retaining ring is symmetrically provided with two identical grooves; and the grooves of the inner side and the grooves of the outer side are respectively correspondingly arranged, and the grooves of the inner side are narrower than the grooves of the outer side. Compared with the existing retaining ring, the contact area of the retaining ring for the bearing of the invention and a shaft shoulder is increased by 70 percent; the problems of deformation of the shaft shoulder and the deformation of the retaining ring for the bearing, which are caused by the axial tight locking force, can be avoided; the problem of deformation of the retaining ring for the bearing, which is caused by the axial fluctuation force of the rotation of a wind blade, can be avoided; and the retaining ring for the bearing can replace the double-ring (bead ring and retaining ring for the bearing) combined structure in the prior art, and has the advantages of simple assembly and high safety and reliability.
Description
Technical field
The present invention relates to a kind of component of machine, particularly a kind of end ring.
Background technique
The motor bearings back-up ring is the axial position that is used for fixing bearing.The structure of the end ring 1 of prior art as shown in Figure 1, it is a notched ring sheet structure, its internal diameter is less than the internal diameter of the bearing that is connected, ring outer side 11 is continuous arc-shaped structure, the inboard mid point both sides at ring of ring respectively are provided with a groove 12,13 that size is identical, and the width of this groove and groove are suitable to the distance of the breach of ring.Gross distortion even back-up ring, can take place and break away from the shaft shoulder during greater than 6.5N in axial locking power (impact) in the end ring of this structure.In order to address this problem, when axial locking power during greater than 6.5N, prior art generally adopt steel traveler+end ring two the circle fabricated structures, its installment state as shown in Figure 2, shown in Fig. 2,1 is the end ring of prior art, 3 is locking nut, and 4 is the fan blade inserts, and 5 is bearing, 6 is axle, and 7 is steel traveler.But this construction cost is high and the assembling trouble, particularly when assembling such as end ring place not in placely, end ring has crushed risk.
Summary of the invention
Purpose of the present invention is to overcome the problem that above-mentioned prior art exists, and a kind of end ring of new structure is provided.
The object of the present invention is achieved like this: a kind of end ring, it is a notched ring sheet structure, be characterized in, the outside of described back-up ring is provided with two grooves that size is identical in the mid point bilateral symmetry of ring, the inboard of back-up ring is provided with two grooves that size is identical in the mid point bilateral symmetry of ring, inboard groove and the corresponding setting respectively of outside groove, and the width of inboard groove is less than the width of outside groove.
Described two inboard grooves are separated into three sections with the internal diameter circular arc of back-up ring, and three sections arc length are roughly the same, and all greater than the arc length of groove institute cutout portion.
Described inboard groove is narrow outer wide trapezoidal in being.
End ring of the present invention is owing to adopted above technological scheme, back-up ring increases by 70% with the area of contact of the shaft shoulder than existing back-up ring, improved the axial strength of back-up ring greatly, shaft locking power can be born, the shaft shoulder distortion and the end ring problem on deformation that cause because of axial locking power can be improved smaller or equal to 10N; Can improve the end ring problem on deformation that causes because of fan blade rotation axial float power; Reliability obviously is better than existing back-up ring.Two circle fabricated structures of the steel traveler+end ring of the alternative prior art of end ring of the present invention, cost is original 1/10, assembling is simple, and is safe and reliable, can reduce neglected loading, helps mistake proofing.

Embodiment
Referring to Fig. 3, end ring 2 of the present invention, it is a notched ring sheet structure, the outside of back-up ring is provided with two grooves 21,22 that size is identical in the mid point bilateral symmetry of ring, the inboard of back-up ring is provided with two grooves 23,24 that size is identical in the mid point bilateral symmetry of ring, inboard groove and the corresponding setting respectively of outside groove, and the width of inboard groove is less than the width of outside groove.Two inboard grooves are narrow outer wide trapezoidal in being, and two inboard grooves are separated into three sections with the internal diameter circular arc of back-up ring, and three sections arc length are roughly the same, and all greater than the arc length of groove institute cutout portion.
Referring to Fig. 4, Fig. 4 is the user mode schematic representation of end ring of the present invention.Shown in the figure, 2 is end ring of the present invention, and 3 is locking nut, and 4 is the fan blade inserts, and 5 is bearing, and 6 is axle.As seen comparison diagram 4 and Fig. 2 adopt end ring of the present invention, two circle fabricated structures of the steel traveler+end ring of alternative prior art.
Fig. 5 is the contact condition schematic representation of the prior art end ring and the shaft shoulder.Shown in the figure, 61 is the shaft shoulder, and A indication oblique line partly is the area of contact of the prior art end ring 1 and the shaft shoulder 61.Fig. 6 is the contact condition schematic representation of the end ring of the present invention and the shaft shoulder.Shown in the figure, 61 is the shaft shoulder, and B indication oblique line partly is the area of contact of end ring 2 of the present invention with the shaft shoulder 61.By Fig. 5, Fig. 6 as seen, adopt end ring 2 of the present invention, its area of contact with the shaft shoulder 61 is more much bigger with the area of contact of the shaft shoulder 61 than adopting prior art end ring 1, area of contact has approximately increased by 70%, can improve the problem that the shaft shoulder is out of shape and end ring is out of shape that axial locking power causes thus greatly, also can improve the end ring problem on deformation that causes because of fan blade rotation axial float power.
