Abstract
The present invention relates to a kind of deep groove ball bearing with grease holes with retainer and the deep groove ball bearing made with above-mentioned retainer, retainer wherein, comprise the support body I and the support body II that can be docking together, support body I and support body II comprise ball pocket and the plane that is arranged alternately, wherein, the ball pocket surface of support body I and/or support body II is provided with grease holes.Grease holes is arranged on the non-dot location of an arc section, the dead in line of the center line of arc section and support body I, and its radius is the perpendicular distance of the center line of grease holes to the axis of support body I.The outstanding advantage of the present invention is: the ball pocket is provided with grease holes, grease can be entered between the ball pocket and rolling element of retainer easily, high lubricating effect, effectively improve the greasy property of bearing, reduce friction, reduction sound is little, vibrates low, make bearing have good riding quality reliably, thereby make bearing be more suitable for running up and prolonged working life of bearing.
Description
Technical field:
The present invention relates to technical field of bearings, particularly a kind of deep groove ball bearing with grease holes is with retainer and deep groove ball bearing.
Background technique:
Deep groove ball bearing comprises inner ring, outer ring, retainer and rolling element, and retainer is equally spaced with rolling element, is distributed on the raceway circumference when preventing work to run foul of each other and rub between rolling element, and guiding also drives rolling element and rolls on correct raceway; The present retainer that adopts, mostly be the two halves formula greatly, promptly couple together by rivet by the identical annular frame of the two halves that are docking together, support body comprises ball pocket and the plane that is arranged alternately, half support body is provided with rivet, second half support body is provided with rivet hole, and the ball pocket of this kind retainer and rolling element assembling back guide clearance are little, and lubricant medium is difficult to enter, retainer inboard and rolling element 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 objective of the invention is to overcome the shortcoming that exists in the prior art, provide a kind of simple in structure, the deep groove ball bearing of the band grease holes of high lubricating effect is with retainer and deep groove ball bearing.
To achieve these goals, the invention provides a kind of deep groove ball bearing retainer with grease holes, comprise the support body I and the support body II that can be docking together, support body I and support body II comprise ball pocket and the plane that is arranged alternately, wherein, the described ball pocket surface of described support body I and/or described support body II is provided with grease holes.
In order better to realize above-mentioned purpose, the present invention can be by the following technical solutions:
Described grease holes is arranged on the non-dot location of an arc section, the dead in line of the center line of described arc section and described support body I, and its radius is the perpendicular distance of the center line of described grease holes to the axis of described support body I.
In order better to realize above-mentioned purpose, the present invention can also be by the following technical solutions:
Described grease holes is provided with in pairs, and is symmetricly set on the both sides, summit of described arc section.
Described grease holes is circle, ellipse, triangle, square or polygonal.
To achieve these goals, the deep groove ball bearing made of the present invention's retainer of also providing a kind of utilization to have above-mentioned feature.
The outstanding advantage of the present invention is: the ball pocket is provided with grease holes, grease can be entered between the ball pocket and rolling element of retainer easily, high lubricating effect, effectively improve the greasy property of bearing, reduce friction, reduction sound is little, vibrates low, make bearing have good riding quality reliably, thereby make bearing be more suitable for running up and prolonged working life of bearing.
