Abstract
The utility model discloses a dedicated disc type maintainer for a cylindrical roller bearing. The maintainer is in an integral structure. The cross section of the maintainer is convex; the structural form of the maintainer is that cylindrical pocket holes (1) are distributed at intervals; and lock mouths (2) are machined at the bottom ends of the cylindrical pocket holes (1). A certain lock amount is ensured. A trapezoid oil groove (6) is formed in the external diameter (5) of the maintainer, and oil filling holes (7) are distributed uniformly at the bottom of the oil groove (6). A semicircular lubricating oil groove (8) and oil filling holes (9) are formed in the end surfaces (3) of the pocket holes (1), the oil filling holes (9) are communicated with external diameter oil filling holes (7), and the end surface (3) of each pocket hole extends to both sides to form a fan shaped accommodation space. According to the utility model, by using the dedicated disc type maintainer for the cylindrical roller bearing, the assembly performance and lubrication effect of a bearing are improved, the performance of a rolling element led by the maintainer during rotation is improved, the strength of the maintainer is strengthened, and defects of a previous structure are compensated. The disc type maintainer has the characteristics of high reliability, long service life, stable running and the like.
Description
Technical field
The utility model belongs to a kind of bearing cage, relates generally to a kind of structural type of disc type retainer of roller bearing special use.
Background technique
The disc type retainer of at present roller bearing use is shaped as plate-like.It is subject to bearing interior space and bearing structure, so volume ratio is thiner, and retainer external diameter and outer ring raceway gap are narrow and small, and lubricant oil is difficult for flowing in the bearing inner loop, and lubrication effect is general.The LSL series roller bearing of conventional FAG brand, the retainer build is thin, and the situation of retainer beam fracture occurs under case of heavy load easily, or axially dislocation skew occurs rolling element.And the utility model is improved on original disc type retainer architecture basics.At the distolateral guiding area that increased of retainer, and the oilhole that has increased the ring type oil groove and communicated at retainer external diameter and end face.
Summary of the invention
The purpose of this utility model is: can improve retainer guiding rolling element in the assembly performance of bearing and lubrication effect, the raising rotary course performance, increased retainer intensity, remedy the deficiency of old structure, had the characteristics such as reliability height, load height, long service life, smooth running.
The purpose of this utility model can adopt following technological scheme to realize: described retainer is the integrity entity structure, and the retainer cross section is convex, the structural type that cylindrical pocket span distributes, and the bottom in cylindrical pocket hole is processed into straight mouthful.Size is slightly little than rolling element diameter, guarantees certain hold depth, and the outer assembly that is comprised of outer ring, retainer, rolling element after the assembling moulding forms overall structure.The retainer external diameter has trapezoidal oil groove, uniform oil hole in the oil groove.The retainer end face has oil groove and oil hole equally, and end face oil hole and external diameter oil hole join, and makes the oil groove oilhole of retainer form the lubrication system that a cover evenly links up.
The beneficial effects of the utility model are: integral holder assembly performance described in the utility model is good; Because the outer ring is subdivision structure radially, can retainer and rolling element be installed from bearing face behind the subdivision of outer ring, by lock ring two semi outer rings connections are formed outer assembly again; Below processing fore shaft in cylindrical pocket hole can effectively pin rolling element, prevents that rolling element from deviating from outer assembly; Extend to two ends in cylindrical pocket hole, forms fan-shaped containing, more effectively guides rolling element to rotate, and prevents rolling element in the inner situation that axial dislocation skew occurs of bearing, thereby realize that bearing turns round safely and smoothly.In addition, thus owing to widened the intensity that cross section has increased retainer, reduced the possibility of retainer beam fracture; Keep the external diameter oil groove to be connected by oil hole with the end face oil groove, form lubrication system.Lubricant oil can be stored in the retainer external diameter oil groove after being injected into bearing inside by the outer ring oilhole, then uniformly lubricant oil is spread upon bearing inside by the end face annular oil groove, thereby reaches the effect that improves greasy property.In sum, the utility model has improved assembly performance and the lubrication effect of bearing and has improved the performance of retainer guiding rolling element in the rotary course, has the characteristics such as reliability height, long service life, smooth running.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is the A-A sectional view of Fig. 1.
Among the figure: 1, cylinder type pocket hole, 2, fore shaft, 3, the pocket hole end surface, 4, the retainer internal diameter, 5, the retainer external diameter, 6, trapezoidal oil groove, 7, the external diameter oilhole, 8, semicircle oil groove, 9, the end face oilhole.
Embodiment
By reference to the accompanying drawings, specific embodiment of the utility model is described.
As shown in Figure 1, 2: the retainer cross section is convex, cylindrical pocket hole (1) structural type spaced apart, the bottom processing fore shaft (2) in cylindrical pocket hole.Size is slightly little than rolling element diameter, guarantees certain hold depth, so rolling element can not be deviate from from internal diameter (4) direction after packing into from pocket hole end surface (3).Retainer external diameter (5) has trapezoidal oil groove (6), oil groove bottom uniform oil hole (7).Pocket hole end surface (3) has semicircle oil groove (8) and oil hole (9), and pocket hole end surface oil hole (9) joins with external diameter oil hole (7), forms the coherent uniform lubrication system of a cover.Pocket hole end surface (3) extends to both sides, forms fan-shaped containing, more effectively guides rolling element to rotate, and prevents rolling element in the inner situation that axial dislocation skew occurs of bearing, thereby realizes that bearing turns round safely and smoothly.
Claims (1)
1. the disc type retainer of a roller bearing special use, it is characterized in that: described retainer is the integrity structure, the retainer cross section is convex, cylindrical pocket hole (1) structural type spaced apart, the bottom processing fore shaft (2) in cylindrical pocket hole, guarantee certain hold depth, retainer external diameter (5) has trapezoidal oil groove (6), oil groove bottom uniform oil hole (7), pocket hole end surface (3) has semicircle oil groove (8) and oil hole (9), pocket hole end surface oil hole (9) joins with external diameter oil hole (7), and pocket hole end surface (3) extends to both sides, forms fan-shaped containing.
