Description
Technical field
The utility model belongs to the retainer technical field, and what relate generally to is a kind of deep groove ball bearing.
Background technique
The retainer that deep groove ball bearing is commonly used has steel plate punching press ribbon retainer, engineering plastics cage and car manufacture-yellow copper or bronze two retention tabs.Middle-size and small-size deep groove ball bearing generally adopts steel plate punching press ribbon retainer, and its intensity is better, and weight is also light.That engineering plastics cage has is in light weight, self-lubricating property good, the advantage of shock-resistant, antivibration and noise reduction, but also have poor dimensional stability, damp and hot expansion is big, intensity is low, the weakness of resistance to heat difference.These two kinds of retainers are used in lower, the occasion stably of loading of rotating speed usually.If bearing rotating speed height, acceleration are big or bear heavy load, impact load, then consider from lubricated and intensity aspect, need to adopt copper cage.But generally there are a lot of problems in existing copper cage aspect lubricated and the intensity: the retainer guide clearance is little, lubricant medium is difficult to enter, retainer radial-play amount is big, easy and retainer external diameter or internal diameter generation friction, wearing and tearing and heating of lasso rib had a strong impact on the normal operation of deep groove ball bearing when running up.
Summary of the invention
The purpose of this utility model is the deficiency at existing above-mentioned technology, has proposed a kind of deep groove ball bearing that retainer intensity is big and greasy property is good that has.
The purpose of this utility model can realize by following technical proposal: a kind of deep groove ball bearing, comprise bearing inner race, bearing outer ring and have the ball of retainer, be provided with raceway between described bearing inner race and the bearing outer ring and above-mentioned ball is positioned at this raceway, described bearing inner race and both sides, bearing outer ring junction are provided with dust cover, it is characterized in that, the described retainer outside is provided with stiffening ring, and described bearing outer ring inboard is provided with annular shallow slot and shallow slot between dust cover and raceway.
The stiffening ring that its retainer outside is provided with can better make retainer fix, keep its intensity, add in the bearing outer ring inboard annular shallow slot is set, lubricant medium just is easy to enter retainer like this, therefore when running up, can better avoid lasso rib and retainer external diameter or internal diameter when deep groove ball bearing and produce friction, wearing and tearing and heating, thereby make its normal operation.
In above-mentioned deep groove ball bearing, described retainer is formed by fixedly connecting by two annular retaining sheets.
Two annular retaining sheets forming retainer are fixed together, like this deep groove ball bearing in running, with regard to can not take place because of the operation that two annular retaining sheets come off or problem such as become flexible is brought undesired.
In above-mentioned deep groove ball bearing, be equipped with the pocket hole on described each retention tab, described pocket hole shape is a hemisphere, two its pocket hole shapes of annular retaining sheet butt joint back are spherical pocket hole.
Be provided with hemisphere pocket hole on each retention tab, its pocket hole shape of such two annular retaining sheets butt joint back is spherical pocket hole, and in assembling, ball is installed in the cage ball pocket.
In above-mentioned deep groove ball bearing, all have groove on described retainer internal diameter and the external diameter.
In the deep groove ball bearing, on retainer internal diameter and external diameter, all have groove, increased the retainer guide clearance, thereby lubricant medium is entered easily.
In above-mentioned deep groove ball bearing, described stiffening ring and retainer are fixed together by rivet.
In the deep groove ball bearing, on retainer, be fixed with stiffening ring, strengthened the intensity of retainer by rivet.
In above-mentioned deep groove ball bearing, the shallow slot cross section on the described bearing outer ring is a circular arc.
According to the application target difference, can the shallow slot Cross section Design is in the arc-shaped.
In above-mentioned deep groove ball bearing, the shallow slot cross section on the described bearing outer ring is the conical surface.
According to the application target difference, the shallow slot Cross section Design can be become the conical surface.
Compared with prior art, retainer in this deep groove ball bearing is provided with groove on internal diameter and external diameter, increased the retainer guide clearance, thereby can lubricant medium be entered, and also be fixed with stiffening ring on this retainer by rivet, strengthen the intensity of retainer, guaranteed the operation of deep groove ball bearing stability and safety.
