Abstract
The utility model provides a ball bearing cage with lubricating oil holes and grease storing grooves, and belongs to the technical field of bearing cages, and the ball bearing cage is mainly used for solving the problems that existing lubricating media are difficult in entering a cage and ball pockets and steel ball bodies on the inner side of the cage can not be well lubricated, so that the ball pockets and the steel ball bodies rub seriously, have big noises and easily emit heat and sometimes cage fracture can happen, so that bearings are damaged and have short service lives and normal operations of the bearings are seriously affected. The ball bearing cage is mainly characterized by comprising a cage body formed by butt-jointing two semicircular cage bodies by rivets, wherein ball pockets and planes are alternately arranged on the semicircular cage bodies; the ball pockets of the semicircular cage bodies are provided with the lubricating oil holes and the grease storing grooves. The ball bearing cage has the characteristics that the ball bearing cage has a simple structure; grease can conveniently enter the spaces between the ball pockets and steel balls of the cage under the action of centrifugal forces; the ball bearing cage has good lubricating effects.
Description
Technical field
The utility model belongs to the retainer technical field, is specifically related to a kind of ball bearing retainer with oilhole and grease storage groove.
Background technique
Deep groove ball bearing comprises inner ring, outer ring, retainer and rolling element, and retainer is distributed on steel ball on the raceway groove circumference when preventing work and runs foul of each other and rub between steel ball, and guiding also drives steel ball and rolls at correct raceway.The present retainer that adopts, mostly be the two halves formula greatly, namely connected by rivet by the essentially identical annular frame of two halves and be docking together, keep support body to comprise ball pocket and the plane that is arranged alternately, the ball pocket of this kind retainer and steel ball assembling back guide clearance are little, lubricant medium is difficult to enter, retainer inside ball pocket and steel ball body can not get good lubricating, friction phenomenon is very serious, and noise is big, easily heating, the thing of retainer fracture also can take place sometimes, cause damage of bearings, working life is short, has had a strong impact on the normal operation of bearing.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming that exists in the existing structure retainer, and a kind of simple in structure, ball kicking strap oilhole of high lubricating effect and the ball bearing retainer of grease storage groove are provided.
To achieve these goals, technical solution of the present utility model is: a kind of ball bearing retainer with oilhole and grease storage groove, comprise by the two halves annular frame and connect the retainer that is docking together and constitutes by rivet, ball pocket and plane alternately are set on the semi-circular support body, it is characterized in that: the ball pocket of described semi-circular support body is provided with lubrication hole and grease storage groove.
Lubrication hole described in the technical solution of the present utility model is arranged on the interior position, center circle summit of ball pocket, and grease storage groove is opened in the both sides of this lubrication hole.
Lubrication hole described in the technical solution of the present utility model is circular port, and grease storage groove is rectangular slot.
The outstanding advantage of the utility model is: the center is provided with lubrication hole and grease storage groove in the ball pocket, lubricating grease can be entered between the ball pocket and steel ball of retainer easily, high lubricating effect, effectively improve the greasy property of bearing, reduce friction, reduce the sound, vibrate low, make bearing have good riding quality reliably, thereby make bearing be more suitable for running up and prolonged working life of bearing.The utility model is mainly used in the ball bearing retainer with oilhole and grease storage groove.
Description of drawings

Fig. 2 is A-A view of Fig. 1.
Fig. 3 is the cutaway view Amplified image after the assembling of the utility model retainer connects.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1 and Figure 2.Semi-circular support body comprises ball pocket 1, plane 2, lubrication hole 3 and grease storage groove 3-1,3-2, rivet hole 4, and ball pocket 1 and plane 2 are arranged alternately, the uniform rivet hole 4 in 2 centers, plane.As shown in Figure 3, it is the example structure figure of the retainer that the two halves annular frame is connected and composed by rivet and rivet hole 4 of the present utility model, wherein, semi-circular support body 6 is identical with semi-circular support body 7 structures, and symmetry is placed, connect semi-circular support body 6,7 be rivet 5, rivet 5 connects by rivet hole 4, retainer ball pocket 1 center after the connection is provided with lubrication hole 3 and grease storage groove 3-1, the 3-2 of symmetry, and lubrication hole 3 is circular, and grease storage groove 3-1, the 3-2 of lubrication hole 3 both sides is rectangular.Grease can be entered between the ball pocket 1 and steel ball of retainer easily.
Lubrication hole can also be the through hole of round taper hole or other shape.Grease storage groove can also be that elliptical slot, rectangle add curve bath etc.
