Abstract
The invention discloses a deep groove ball bearing of a steel ball guiding solid retainer structure, and belongs to the field of bearing manufacture. The deep groove ball bearing comprises an outer ring, an inner ring, a rivet, a steel ball and a retainer; the outer ring and the inner ring are respectively provided with roller paths; the steel ball is loaded in a pocket hole of the retainer; the retainer comprises a retainer base and a retainer cover which are mutually connected through the rivet; the retainer is in the solid retainer structure; and the wall surface of the pocket hole is in a funnel-shaped structure. The deep groove ball bearing has the advantages that a bearing retainer is optimally designed, a stamping retainer structure is designed into a solid retainer structure, a straight pocket hole of the solid retainer is changed into a funnel-shaped hole in a mode that a straight hole and a cone hole are intersected with each other, the steel ball is locked in the lower cone hole, the angle of the cone hole is reasonably designed, so that the tangential point between the cone hole and the steel ball is positioned in a proper position, the operation stability of the steel ball is guaranteed, the effect of ball guiding is achieved, and the use requirements on high speed and high strength of the deep groove ball bearing are satisfied.
Description
Technical field
The present invention relates to a kind of deep groove ball bearing of steel ball guiding solid cage structure, belong to bearing and make the field.
Background technique
Along with making rapid progress of domestic and international science and technology, the industries such as motor, elevator have also obtained development fast.Especially in contemporary electromechanical industries, at a high speed, steadily become industry development trend.Therefore for the high speed that adapts to main frame in the industries such as motor, elevator, the demand of smooth operation, it is more and more important that the performance of the high-speed bearing that matches with it just seems.
At present, bearing is divided into inner ring guiding, outer ring guiding, three kinds of guidance modes of ball guiding.And domestic deep groove ball bearing needs to adopt the mode of ball guiding in order to reach fair speed.
Adopt the ball guiding can greatly improve rotating speed, but ball guiding in the past all will be adopted the steel plate punched retainer, but in the situation that heavy duty, the intensity of pressing cage does not reach requirement, therefore be badly in need of to research and develop a kind of solid cage bearing of ball guiding, to reach the requirement of main frame high-speed and high-intensity, therefore study a kind of special construction ball guiding entity frame deep groove ball bearing, imperative.
Summary of the invention
In view of the defective that prior art exists, the present invention will provide a kind of deep groove ball bearing that is optimized the steel ball guiding solid cage structure of design for retainer.
To achieve these goals, technological scheme of the present invention is:
The deep groove ball bearing of steel ball guiding solid cage structure, formed by outer ring, inner ring, rivet, steel ball, retainer, outer ring, inner ring are respectively equipped with raceway, steel ball is loaded in the pocket hole of retainer, described retainer is by keeping stand and retainer lid to form, connected by rivet, it is characterized in that: described retainer is solid cage structure, and its pocket wall surface of the hole is funnel-shaped structure.
Further, described pocket wall surface of the hole is divided into two-part in the radial direction retainer, and top is divided into the straight hole structure, and the bottom is divided into the taper hole structure, and straight hole and taper hole intersect and form funnel shape pocket hole structure.
Further, described taper hole angle is 40 ° ~ 60 °.
Excellent effect of the present invention: the present invention is optimized design for retainer, change is designed to solid cage structure with pressing cage structure, and the straight pocket hole of solid cage is become the funnel-shaped hole that straight hole and taper hole intersect, steel ball is locked in the taper hole of below; The angle of appropriate design taper hole makes the point of contact of taper hole and steel ball in place, guarantees that ball operates steadily, and reaches the effect of ball guiding, satisfies the usage requirement of deep groove ball bearing high-speed and high-intensity.

Fig. 2 is the deep groove ball bearing structural representation of common solid cage structure;
Fig. 3 is steel ball guiding solid cage structure schematic diagram;
Fig. 4 is common solid cage structure schematic diagram.
In figure: 1, outer ring, 2, inner ring, 3, rivet, 4, steel ball, 5, keep stand, 5a, straight hole, 5b, taper hole, 6, the retainer lid.
Embodiment
Further illustrate technological scheme of the present invention below in conjunction with accompanying drawing:
As shown in Fig. 1,3, the present invention is comprised of outer ring 1, inner ring 2, rivet 3, steel ball 4, retainer, outer ring 1, inner ring 2 are respectively equipped with raceway, steel ball 4 is loaded in the pocket hole of retainer, described retainer is by keeping stand 5 and retainer lid 6 to form, connected by rivet 3, it is characterized in that: described retainer is solid cage structure, and its pocket wall surface of the hole is funnel-shaped structure.The pocket wall surface of the hole is divided into two-part in the radial direction retainer, and top is divided into straight hole 5a structure, and the bottom is divided into taper hole 5b structure, and straight hole 5a and taper hole 5b intersect and form funnel shape pocket hole structure.
(as Fig. 2,4) compares with existing deep groove ball bearing, of the present invention retainer carried out design innovation, changes straight pocket hole into " funnel " shape pocket hole that straight hole 5a and taper hole 5b intersect, effectively carries out the ball guiding.The pocket hole is funnel-shaped hole, can effectively steel ball be locked in the taper hole 5b of below; The angle of appropriate design taper hole 5b makes the point of contact of taper hole 5b and steel ball in place, guarantees that ball operates steadily, and reaches the effect of ball guiding.
The taper hole angle is at 40 ° ~ 60 °, concrete numerical value is determined to the perpendicular distance the retainer internal diameter by the point of contact of steel ball and the pocket hole conical surface, this distance must be greater than 2mm, thus apart from the anti-concrete angle value that pushes away taper hole, the gained angle value will round, and therefore obtaining taper hole angle zone of reasonableness is 40 ° ~ 60 °.
