Abstract
The utility model relates to a ball retainer for a combined type one-way bearing. Based on the technical proposal provided by the utility model, the left end face of the circle shaped right lateral board is provided with a plurality of retaining units which are arranged in interval. The left end part of each retaining unit is provided with constraint sag in a spherical calotte shaped wall body shape. The two connecting retaining units are integrated together through a connecting body. The left end part and the two sides - the upper side and the lower side of the constraint sag are all provided with open ends. The depth of the constraint sag is larger than the diameter of the sphere. The radius of the circle corresponding to the partial arc formed by the open ends on the upper side and the lower side of the constraint sag is less than the radius of the spherical calotte shaped wall body of the constraint sag. After the utility model is installed and used, the retainer and the rollers are matched firmly, and the looseness is not easily to be caused even the bearing is operated for a long time. The strange sound can not be produced when the one-way bearing is worked, and the roller is not easily to fall off from the retainer; and the working efficiency of the machinery can be avoided from being lowered.
Description
Technical field
The utility model relates to a kind of Ball retainer, especially a kind of ball retainer of combined type unilateral bearing.
Background technique
On frame and printing machinery, generally use unilateral bearing, general unilateral bearing comprises inner ring, outer ring and the clutch inner core between them, voussoir roller, loam cake, lower cover, retainer, gulde edge, tightens up parts formations such as spring, spring groove and cross bar at present, retainer in this unilateral bearing and voussoir roller are at the long-time back matching loose easily that uses, produce abnormal sound when making unilateral bearing work, and voussoir roller slippage from retainer easily, the actual use of influence machinery reduces mechanical working efficiency.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, even a kind of ball retainer that firmly the also difficult generation of long-play is loosening, ball is difficult for the combined type unilateral bearing of slippage from retainer that cooperates with ball is provided.
The technological scheme that provides according to the utility model, be provided with the holding part unit that some intervals are provided with in the left side of circular right sideboard, the left part of each holding part unit is provided with the constraint depression that is spherical calotte shape wall body, link to each other and be one by the connecting body connection between the two holding part unit, the left part of constraint depression reaches up and down, and both sides are uncovered, the degree of depth of constraint depression is greater than its sphere radius corresponding, and the radius of a circle of the partial arc correspondence of the uncovered formation in both sides up and down of constraint depression is less than the spherical shape wall body radius corresponding of constraint depression.
Link to each other with the connecting body outer of ring bodies of formation, holding part unit is protruded in the outer of right sideboard.The holding part unit protrudes between adjacent two connecting bodys.
After the utility model is installed and used, cooperate firmly with ball, loosening even long-play also is difficult for producing, can not produce abnormal sound when making unilateral bearing work, ball is difficult for slippage from retainer, avoids reducing the working efficiency of machinery.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: be provided with the holding part unit 2 that some intervals are provided with in the left side of circular right sideboard 1, the left part of each holding part unit 2 is provided with the constraint depression 3 that is spherical calotte shape wall body, the left part of constraint depression 3 reaches up and down, and both sides are uncovered, the degree of depth of constraint depression 3 is greater than its sphere radius corresponding, and the radius of a circle of the partial arc correspondence of the uncovered formation in both sides up and down of constraint depression 3 is less than the spherical shape wall body radius corresponding of constraint depression 3.Link to each other with the connecting body outer of ring bodies of formation, holding part unit is protruded in the outer of right sideboard.The holding part unit is from protruding between adjacent two connecting bodys 2.
The utility model is because the left part of its holding part unit 2 is provided with the constraint depression 3 that is spherical calotte shape wall body, the left part of constraint depression 3 reaches up and down, and both sides are uncovered, the degree of depth of constraint depression 3 is greater than its sphere radius corresponding, and the radius of a circle of the partial arc correspondence of the uncovered formation in both sides up and down of constraint depression 3 is less than the spherical shape wall body radius corresponding of constraint depression 3, when using, ball is positioned at constraint depression 3, the spherical calotte wall body of constraint depression 3 is just embraced ball, there is less gap between ball and the spherical calotte wall body, make constraint depression 3 cooperate firmly with ball, even it is loosening that long-play also is difficult for producing, ball is difficult for slippage from retainer.
