Abstract
The utility model relates to the technical field of rolling bearings, and specifically relates to a deep groove ball bearing, which comprises an outer ring, an inner ring, steel balls and cages, wherein the cages and a filling slot are arranged between the inner and outer rings, and the steel balls are arranged on the cages; and the upper end of the side of a steel ball rolling track of the inner ring is provided with a first fillet and a second fillet, and the filling slot comprises a ball storage slot and a ball inlet which are connected. By arranging the first fillet and the second fillet at the upper end of the side of the steel ball rolling track of the inner ring, a working procedure is added, but the phenomenon that the surfaces of the steel balls are scratched in assembly is greatly improved, and the value of vibration is greatly reduced. The filling slot provided by the utility model is different from the filling slot in the prior art, and the steel balls needing to be installed are firstly embedded into the ball storage slot, and then are pressed into the cages through the ball inlet, so that the operation is very convenient and simple.
Description
Technical field
The utility model relates to technical field of rolling bearings, is specially a kind of deep groove ball bearing.
Background technique
Deep groove ball bearing is widely used in the every field of the national economic development, is a kind of of rolling bearing application quantity maximum.It also is one type the most common in the rolling bearing.The deep groove ball bearing of basic model is by an outer ring, and an inner ring, one group of steel ball and one group of retainer constitute.Some application is to the vibration of main frame, there is higher requirement aspect such as noise and bearing capacity, this depends primarily on vibration values and the steel ball number of deep groove ball bearing, and the reason that influences bearing vibration value is more, also complicated, main factor is steel ball quality, because deep groove ball bearing is inseparable bearing, its last ball generally is to rely on mechanical external force to make race deformation, depress inner ring embedded then, existing bear inner ring grooved railway and external diameter surface are acute angle, during assembling, be easy to steel ball is scratched, therefore, even use high-precision steel ball, vibration values still can not be up to standard, and simultaneously, because at present the deep groove ball bearing of producing is owing to be subjected to the restriction of part assembling, the steel ball of the negligible amounts of can only packing into, this has just caused the bearing capacity of the corresponding deep groove ball bearing of producing less, can not the satisfy the demand requirement of high bearing capacity, certainly, also promisingly in the prior art address this problem improved correlation technique, be generally the inclined-plane breach is set between inner ring and outer ring, though can solve the less problem of steel ball number of packing into substantially, but its assembly process is difficulty comparatively, and inconvenient operation still is unfavorable for utilization and extention.
The model utility content
The purpose of this utility model is to overcome the shortcoming and defect of prior art, provides a kind of avoiding to scratch steel ball in dress ball process, and the deep groove ball bearing of the steel ball of packing into quickly and easily.
A kind of deep groove ball bearing of the present utility model is achieved through the following technical solutions:
A kind of deep groove ball bearing, it comprises outer ring, inner ring, steel ball and retainer, be provided with retainer and a filling slot between described inner ring and the outer ring, described retainer is provided with steel ball, the steel ball rolling rail side upper end of described inner ring is provided with first fillet and second fillet, described filling slot comprises deposits segment mouth and ball hole, and the described segment mouth of depositing is connected with ball hole.
The radius of described first fillet is 2.5～5 centimetres, and the radius of described second fillet is 2.5～5 centimetres.
The described segment mouth of depositing comprises first circular groove and second circular groove, and the opening of described first circular groove and second circular groove is oppositely arranged.
The groove depth of described first circular groove and second circular groove is 0.1～0.3 centimetre.
Compared with prior art, a kind of deep groove ball bearing of the present utility model, be provided with first fillet and second fillet by the steel ball rolling rail side upper end at inner ring, though increased by a procedure, but scratch the phenomenon of steel ball surface when having improved assembling greatly, reduction to vibration values has big benefit, filling slot of the present utility model is different from the filling slot of prior art, can earlier the steel ball that needs to install be embedded and deposit the segment mouth, be pressed in the retainer from ball hole again, very convenient, operate very succinct.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described.
Shown in Fig. 1,2 and 3, a kind of deep groove ball bearing of the present utility model, it comprises outer ring 1, inner ring 2, steel ball 3 and retainer 4, be provided with retainer 4 and a filling slot 5 between described inner ring 2 and the outer ring 1, described retainer 4 is provided with steel ball 3, the steel ball 3 rolling rail sides upper end of described inner ring 2 is provided with first fillet and second fillet, and described filling slot 5 comprises deposits segment mouth 6 and ball hole, and the described segment mouth 6 of depositing is connected with ball hole.Wherein, the radius of described first fillet is 2.5～5 centimetres, and the radius of described second fillet is 2.5～5 centimetres.The described segment mouth 6 of depositing comprises first circular groove and second circular groove, and the opening of described first circular groove and second circular groove is oppositely arranged.The groove depth of described first circular groove and second circular groove is 0.1～0.3 centimetre.In more detail, the radius of described first fillet is 5 centimetres, and the radius of described second fillet also is 5 centimetres.
Above-described embodiment; it is an example of the present utility model; be not to limit enforcement of the present utility model and interest field, all or technological schemes of being equal to identical with the described content of the utility model claim all should be included in the utility model protection domain.
