Abstract
The invention discloses an entity retainer of a ball bearing. The retainer is of a whole structure and is of a comb shape, and an opening is arranged at one surface of the comb shape; a circular pocket (2) and a cylindrical pocket (3) are arranged on the retainer and are distributed at interval; two locking points (8) which can lock a steel ball are arranged on an opening end (1) of the circular pocket (2); and an inner diameter locking point (6) and an outer diameter locking point (7) which can vertically lock a steel ball are arranged on an inner diameter (4) and an outer diameter (5) of the cylindrical pocket (3). The entity retainer provided by the invention has an improvement on the assembly performance of the bearing, has the characteristics of locking amount provision, precise guide, complete lubrication, low vibration, low noise, high rigidity, low friction, high reliability, stable and flexible operation, easy disassembly, low cost and the like and greatly prolongs the service life of the bearing.
Description
Technical field
The invention belongs to a kind of retainer, relate generally to the structural type of a kind of deep groove ball bearing and angular contact ball bearing solid cage.
Background technique
What at present, super-huge (external diameter is more than 400mm) deep groove ball bearing and angular contact ball bearing adopted is the pectination solid cage of an opening.The pocket hole of this structure retainer is circular straight pocket hole, and its overall performance is good, be beneficial to and install and dismounting; Because the pocket hole shape of retainer is circular straight pocket hole; Can not well contain steel ball, make steel ball can't correctly guide the retainer rotation, can only adopt the structural type of lasso lip-guided retainer rotation; Because the gap is less between the internal diameter (or external diameter) of lasso rib and retainer; Make that internal diameter (or external diameter) area of contact of lasso rib and retainer is bigger, be prone to produce friction noise and frictional heating phenomenon, and the very difficult bearing inside that gets into of lubricant grease is carried out lubricated fully; Cause bearing very fast, and temperature is higher because of lubricated insufficient temperature rise that produces.
Summary of the invention
The purpose of this invention is to provide a kind of ball bearing solid cage; It has improved the assembly performance of bearing; Have the hold depth of carrying, guiding is more accurate, lubricated more fully, low vibration, low noise, high rigidity, low friction, reliability height, long service life, running steadily, flexible, be beneficial to and dismantle and characteristics such as with low cost.
The object of the invention can adopt following technological scheme to realize: described retainer is the integrity structure, and retainer is the pectination of an opening, has circular pocket hole and cylindrical pocket hole on it, and circular pocket hole and cylindrical pocket span distribute; Have two lock points that can pin steel ball respectively on one end in circular pocket hole; Has the lock point that can pin steel ball up and down on the internal diameter in cylindrical pocket hole, the external diameter respectively.
The invention has the beneficial effects as follows: integral cage assembly performance of the present invention is good; The pectinate texture form of an opening makes things convenient for steel ball from the retainer one end pocket hole of packing into, has reduced the difficulty of retainer assembly technology; Two symmetry lock points on the circular pocket hole pin steel ball, can prevent that retainer from deviating from bearing; But cylindrical pocket hole maximum area contains the rolling surface of steel ball; Thereby realize that bearing turns round safely and smoothly, the lock point on the inside and outside footpath, pocket hole can pin the steel ball in the retainer pocket hole of packing into up and down; Controlled simultaneously the sag of chain of retainer again; Retainer is not contacted with the lasso rib, reduced area of contact, reduced by fricative noise and heating; And the gap is bigger between inside and outside footpath of retainer and the lasso rib, and lubricant grease can successfully get into bearing inside and carry out lubricated fully.In sum; The present invention has improved the assembly performance of bearing; Have the hold depth of carrying, the guiding more accurate; Lubricated more fully, high, the running of low vibration, low noise, high rigidity, low friction, reliability steadily, flexibly, be beneficial to dismounting and characteristics such as with low cost, prolonged the working life of bearing greatly.

Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the B-B sectional view of Fig. 1.
Among the figure: 1, opening end, 2, circular pocket hole, 3, cylindrical pocket hole, 4, internal diameter, 5, external diameter, 6, internal diameter lock point, 7, external diameter lock point, 8, the lock point.
Embodiment
In conjunction with accompanying drawing, specific embodiment of the present invention is described.
Like accompanying drawing 1, shown in 2: described retainer is an overall structure, and retainer is the pectinate texture of an opening, can make things convenient for steel ball from retainer opening end 1 pack into circular pocket hole 2 and cylindrical pocket hole 3, has reduced the difficulty of retainer assembly technology; Two symmetry lock points 8 on the circular pocket hole 2 can prevent that retainer from deviating from bearing; But cylindrical pocket hole 3 maximum areas contain the rolling surface of steel ball; Thereby realize that bearing turns round safely and smoothly, on cylindrical pocket hole 3 internal diameters 4 and external diameter 5, be respectively arranged with internal diameter lock point 6 and external diameter lock point 7, can pin the steel ball in the cylindrical pocket hole 3 of packing into up and down; Controlled simultaneously the sag of chain of retainer again; Retainer is not contacted with the lasso rib, reduced area of contact, reduced by fricative noise and heating; And the gap is bigger between retainer internal diameter 4, external diameter 5 and the lasso rib, and lubricant grease can successfully get into bearing inside and carry out lubricated fully.
As shown in Figure 3: the structural type that circular pocket hole on the retainer 2 and cylindrical pocket hole 3 are spaced apart can make each lock point stressed evenly.
Claims (1)
1. ball bearing solid cage; It is characterized in that: described retainer is the integrity structure; Retainer is the pectination of an opening, has circular pocket hole (2) and cylindrical pocket hole (3) on it, and circular pocket hole (2) is spaced apart with cylindrical pocket hole (3); Have two lock points (8) that can pin steel ball on the opening end (1) in described circular pocket hole (2) respectively; Have the internal diameter lock point (6) and the external diameter lock point (7) that can pin steel ball up and down on the internal diameter (4) in described cylindrical pocket hole (3), the external diameter (5) respectively.
