Abstract
The utility model relates to a kind of band oil storage function low friction four paws construction nylon retainer, comprise retainer body, with the pocket hole of installing steel ball on retainer body, the axial bi-side symmetry of retainer body offers groove, described groove comprises the first Baltimore groove and the second Baltimore groove of radially arranging that arrange along retainer body circumferencial direction, the first Baltimore groove and the second Baltimore groove arranged in a crossed manner and pocket hole is divided into four paws structure.The utility model makes common spherical packet hole into four paws structure, effectively reduces the area of contact of retainer pocket hole and steel ball surface, reduces the friction in steel ball and pocket hole, reduces bearing heating; The groove arranged increases retainer oil storage space, improves bearing lubrication effect; Can bearing noise be reduced, extend the working life of bearing and improve bearing limit speed.
Description
Technical field
The utility model relates to technical field of bearings, particularly relates to the retainer of bearing.
Background technique
Usually, the nylon cages that ball guides, steel ball moves retainer by ball kicking strap and rotates, and the Area comparison that the pocket hole of retainer encases steel ball is large, grease not easily enters between retainer pocket hole and steel ball, because area of contact is larger, and be unfavorable for heat radiation, retainer does not have the structure of oil storage simultaneously, the grease of lasso inside directly can not arrive the position needing lubrication, thus the serious wear of existing ball retainer, its working life is short.
Model utility content
The applicant, for retainer above shortcomings in existing bearing, carries out studying and designing, and develops that a kind of frictional force is little, the band oil storage function low friction four paws construction nylon retainer of high lubricating effect, long service life.
The technological scheme that the utility model adopts is as follows:
A kind of band oil storage function low friction four paws construction nylon retainer, comprise retainer body, with the pocket hole of installing steel ball on retainer body, the axial bi-side symmetry of retainer body offers groove, described groove comprises the first Baltimore groove and the second Baltimore groove of radially arranging that arrange along retainer body circumferencial direction, the first Baltimore groove and the second Baltimore groove arranged in a crossed manner and pocket hole is divided into four paws structure.
Further improvement as technique scheme:
Inside and outside the radial direction of described second Baltimore groove, two ends are respectively with expanding bell-mouth structure of air.
The beneficial effects of the utility model are as follows:
The utility model makes common spherical packet hole into four paws structure, effectively reduces the area of contact of retainer pocket hole and steel ball surface, reduces the friction in steel ball and pocket hole, reduces bearing heating; The groove arranged increases retainer oil storage space, improves bearing lubrication effect; Can bearing noise be reduced, extend the working life of bearing and improve bearing limit speed.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model.
Fig. 2 is main sectional view of the present utility model.
In figure: 1, retainer body; 2, the first Baltimore groove; 3, the second Baltimore groove; 4, steel ball; 5, pocket hole.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1 and Figure 2, the band oil storage function low friction four paws construction nylon retainer of the present embodiment, comprise retainer body 1, with the pocket hole 5 of installing steel ball 4 on retainer body 1, the axial bi-side symmetry of retainer body 1 offers groove, groove comprise the first Baltimore groove 2 and the second Baltimore groove 3, first Baltimore groove 2 radially arranged that arrange along retainer body 1 circumferencial direction and the second Baltimore groove 3 arranged in a crossed manner and pocket hole 5 is divided into four paws structure.
Inside and outside the radial direction of the second Baltimore groove 3, two ends are respectively with expanding bell-mouth structure of air, and what the setting of horn-like structure was easy to grease enters in groove, improves lubrication effect.
In the utility model, two hemisphere face structures retainer encasing steel ball make four paws structure into by the groove of both sides, thus reduce the area of contact of steel ball and retainer, be easy to the storage of grease on retainer, its smooth running, improves the oil storage capacity of retainer, reduces the friction in steel ball and retainer and pocket hole, reduce heating value, extend bearing life.
More than describing is to explanation of the present utility model, and be not the restriction to model utility, the utility model limited range is see claim, and when without prejudice to spirit of the present utility model, the utility model can do any type of amendment.
