Abstract
The utility model discloses a sectional holder of a super-huge type thin-wall ball bearing. The holder is in a sectional structure; the holder takes the shape of a comb with an opening on one side; special pocket holes (2) are formed in the holder at equal distances; two bent claw locking points (6) at which steel balls can be locked are respectively arranged at opening ends (1) of the special pocket holes (2); locking points (7) for vertically locking the steel balls are respectively arranged on the inner diameter (4) and the outer diameter (5) of the special pocket holes (2); a cylindrical convex head (9) is arranged at one end of the holder; a cylindrical groove (10) is formed in the other end of the holder. Due to adoption of the sectional holder, the assembling property of the bearing is improved, the sectional holder has the characteristics of self locking quantity, head-to-end connection, precise guidance, sufficient lubrication, small vibration, low noise, small friction, high reliability, stability and flexibility in operation, dissembling convenience, low cost and the like, and the service life of the bearing is greatly prolonged.
Description
Technical field
The utility model belongs to a kind of retainer, relates generally to a kind of super-huge thin-walled ball bearing segmentation retainer.
Background technique
Known, current super-huge thin-walled ball bearing solid cage structure has: segmentation comb-shaped retainer and nylon spacing block retainer pattern, said structure retainer all exists certain deficiency.
1, segmentation comb-shaped retainer: this structure retainer is circular straight pocket hole, lasso lip-guided form, area of contact is large, easily produces friction noise and heating.
2, nylon spacing block: this structure retainer is only suitable for bearing level and installs, and the applying working condition of low-speed running, is not suitable for bearing at right angle setting, the applying working condition running up.
Summary of the invention
The purpose of this utility model is to provide a kind of super-huge thin-walled ball bearing segmentation retainer, it can improve the assembly performance of bearing, there is the hold depth of carrying, end-to-end, guiding more accurate, lubricated more abundant, low vibration, low noise, low friction, reliability are high, smooth running, flexibly, be beneficial to dismounting and the feature such as with low cost.
The purpose of this utility model can adopt following technological scheme to realize: described retainer is segmenting structure, and retainer is the pectination of an opening, has equidistant spherical packet hole on it; On the opening end of spherical packet hole, there are respectively two curved pawl lock points that can pin steel ball; There is cylindrical nib one end, and the other end has cylinder shape groove.
The beneficial effects of the utility model are: segmentation retainer assembly performance described in the utility model is good; The pectinate texture form of an opening, facilitates steel ball to pack pocket hole into from retainer one end, has reduced the difficulty of retainer assembly technology; On spherical packet hole, two symmetrical curved pawls lock points, pin steel ball, can prevent that retainer from deviating from bearing; Spherical packet hole can maximum area contains the rolling surface of steel ball, thereby realizing bearing turns round safely and smoothly, the lock point of spherical packet hole self-assembling formation, can pin up and down the steel ball packing in retainer pocket hole, controlled again the sag of chain of retainer simultaneously, retainer is not contacted with lasso rib, reduced area of contact, reduced by fricative noise and heating; One end of each section of retainer band cylindrical nib is connected with one end of another section of retainer band cylinder shape groove, form the annulus of a sealing, increased the accuracy of steel ball guiding, and gap is larger between the inside and outside footpath of retainer and lasso rib, lubricant grease can successfully enter bearing inside and lubricate fully.In sum, the utility model has improved the assembly performance of bearing, there is the hold depth of carrying, end-to-end, guiding more accurate, lubricated more abundant, low vibration, low noise, low friction, reliability are high, smooth running, flexibly, be beneficial to dismounting and the feature such as with low cost, greatly extended the working life of bearing.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
The A that accompanying drawing 2 is Fig. 1 is to schematic diagram;
The B-B sectional view that accompanying drawing 3 is Fig. 2;
In figure: 1, opening end; 2, spherical packet hole; 3, center line; 4, internal diameter; 5, external diameter; 6, curved pawl lock point; 7, lock point; 8, end face; 9, plush copper; 10, groove.
Embodiment
By reference to the accompanying drawings, specific embodiment of the utility model is described.
As shown in accompanying drawing 1,2: as described in retainer be segmental structure, retainer is the pectinate texture of an opening, can facilitate steel ball to pack spherical packet hole 2 into from retainer opening end 1, has reduced the difficulty of retainer assembly technology, two symmetrical curved pawls lock points 6 on spherical packet hole 2, can prevent that retainer from deviating from bearing, spherical packet hole 2 can maximum area contains the rolling surface of steel ball, thereby realize bearing safety, running reposefully, the lock point 7 of spherical packet hole self-assembling formation, can pin up and down the steel ball packing in spherical packet hole 2, controlled again the sag of chain of retainer simultaneously, retainer is not contacted with lasso rib, reduced area of contact, reduced by fricative noise and heating, one end of each section of retainer band cylindrical nib 9 is connected with one end of another section of retainer band cylinder shape groove 10, form the annulus of a sealing, increased the accuracy of steel ball guiding, and retainer internal diameter 4, between external diameter 5 and lasso rib, gap is larger, lubricant grease can successfully enter bearing inside and lubricate fully.
As shown in Figure 3: the radius SR of spherical packet hole 2, radius of arc SR1 and end face 8 form curved pawl lock point 6, and the center line 3 of radius of arc SR1 is locked the locking intensity of point 6 lower than the center line 3 of spherical packet hole 2 radius SR to strengthen curved pawl.
Claims (1)
1. a super-huge thin-walled ball bearing segmentation retainer, is characterized in that: described retainer is segmenting structure, and retainer is the pectinate texture of an opening, has equidistant spherical packet hole (2) on retainer; On the opening end (1) of described spherical packet hole (2), there are respectively two curved pawl lock points (6) that can pin steel ball; On the internal diameter (4) of described spherical packet hole (2), external diameter (5), there is respectively the lock point (7) that can pin up and down steel ball; There is cylindrical nib (9) retainer one end, and the other end has cylinder shape groove (10).
