Sealing ring be fixed on the other end of V-arrangement bending part, and be provided with and form lip in sealing contact with inner ring outer ring surface.
The utility model has the beneficial effects that：Using the above structure, since the utility model is in the outer ring surface of inner ring and outer
Full filling segment mouth is additionally arranged between the inner ring surface of circle, therefore compared to traditional deep groove ball bearing, the utility model can be packed into more
The steel ball of quantity, to effectively improve the total bearing capacity of bearing.In addition, since the skeleton of sealing device has, there are one V-arrangements
Bending part, and the elastic component for promoting it to keep opening is provided between the both ends of V-arrangement bending part, thus V-arrangement bending part can be promoted
One end be held securely against on the inner ring surface of outer ring, and enable the sealing ring and inner ring that are fixed on the V-arrangement bending part other end
Outer ring surface forms good in sealing contact, and to compared with prior art, sealing effect is more preferable, and connects more secured, is not easy to take off
It falls, and elastic compensating can be formed to sealing surface after the lip of sealing ring is using abrasion, to further lift-off seal effect, and
Extend bearing service life.
The utility model can be further arranged to this end that the V-arrangement bending part is resisted against on outer ring inner ring face and be additionally provided with
Along the outer ring inner ring face extension that axially fitting extends, and location structure is additionally provided between the extension and outer ring inner ring face.
Be arranged by above structure, not only can preferably stationary positioned skeleton, but also make to be formed between skeleton and outer ring even closer
Fitting, contribute to further lift-off seal effect.
It is to constitute to be mutually inserted the convex block of positioning and recessed that the utility model, which may further be provided as the location structure,
Slot, the convex block, which is integrally formed, to be arranged on the extension, and the groove is opened on outer ring inner ring face.
It is compressed spring that the utility model, which may further be provided as the elastic component, and certainly, the elastic component also may be used
To be the other structures such as shrapnel, the pillar of positioning compressed spring is provided on the inside of the both ends of V-arrangement bending part.
It includes two retainer ontologies, two retainer ontologies that the utility model, which may further be provided as the retainer,
Steel ball both sides are symmetricly set on, and are fixed by rivet, the rivet also covers in the bar portion between two retainer ontologies
Installing is equipped with elastic washer, and the section of the elastic washer is U-shaped, and the both ends of U-shaped elastic washer are pressed on two holdings respectively
On the end face of frame ontology.
Using the above structure, the retainer is divided into two retainer ontologies, then is fixed by rivet, structure letter
It is single, it is easy to assembly.In addition, by adding the elastic washer that section is U-shaped, not only so that having more after the riveting of two retainer ontologies
Good pretightning force, and certain elastic buffer power can also be formed in riveting, it effectively avoids crushing steel ball when riveting.
