Description
Technical field
The utility model relates to a kind of pivoting support, especially a kind of external tooth type pivoting support.
Background technique
Pivoting support is mainly used in Hoisting Machinery, engineering machinery, Transport Machinery, medical machinery, research equipment etc., the external tooth type pivoting support also is wherein use always a kind of, steel ball and spacing block are installed in the raceway of pivoting support, for pivoting support rotates flexibly, need oiling in the raceway, the oilhole of general external tooth type pivoting support is horizontally installed on inner ring, the processing more complicated, some occasion is because the relation of installing causes inner ring blocked or when not having enough spaces, laterally oiling becomes very difficult, steel ball can not get well lubricated, underaction when pivoting support rotates.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of external tooth type pivoting support is provided, the processing of oilhole is simple, and oiling is also convenient, and the steel ball in the raceway obtains better lubricated, and pivoting support rotates flexibly slim and graceful.
The technological scheme that its technical problem that solves the utility model adopts is: have outer ring, inner ring, steel ball, spacing block and Stamping Steel Ribbon, the outer ring has outer raceway, inner ring has interior raceway, and outer raceway cooperates the formation raceway with interior raceway, and steel ball and spacing block are installed in the raceway, the outer ring has the outer ring installation base surface, described outer ring offers oilhole, and oilhole has vertical hole and cross-drilled hole, and vertical hole is opened on the installation base surface of outer ring, cross-drilled hole one end and vertical hole are connected, and the cross-drilled hole the other end is connected with outer raceway.
Offer the outer ring mounting hole on the installation base surface of described outer ring, the center of circle, top of the center of circle, top, described vertical hole and outer ring mounting hole is on same circumference, and oilhole is easy to process.
Because vertical hole is opened on the installation base surface of outer ring, flow into cross-drilled hole from the inside oiling in vertical hole, cross-drilled hole is connected with outer raceway, and oil flows into raceway from cross-drilled hole, the steel ball in the lubricated raceway, when inner ring did not have enough oiling spaces, pivoting support is oiling easily still.
For oiling more easily and protection oilhole are not invaded by dust, oilhole be difficult for to stop up, and also the straight-through type forced filling oil cup can be installed on the vertical hole.
The beneficial effects of the utility model are: oilhole of the present utility model has vertical hole and cross-drilled hole, and vertical hole is opened on the installation base surface of outer ring, and cross-drilled hole is connected with outer raceway, the processing of oilhole is simple, oiling is also convenient, and the steel ball in the raceway obtains better lubricated, and pivoting support rotates flexibly slim and graceful.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the K of Fig. 1 is to schematic representation;
Wherein: 1. outer ring, 2. inner ring, 3. steel ball, 4. spacing block, 5. Stamping Steel Ribbon, 61. outer raceways, raceways in 62., 71. vertical holes, 72. cross-drilled holes, 8. outer ring mounting hole, 9. outer ring installation base surface
Embodiment
The external tooth type pivoting support shown in Figure 2 as Fig. 1, have outer ring 1, inner ring 2, steel ball 3, spacing block 4 and Stamping Steel Ribbon 5, outer ring 1 has outer raceway 61, and inner ring 2 has interior raceway 62, outer raceway 61 cooperates the formation raceway with interior raceway 62, steel ball 3 and spacing block 4 are installed in the raceway.
The last plane of outer ring 1 is an outer ring installation base surface 9, and outer ring 1 offers oilhole, and oilhole has vertical hole 71 and cross-drilled hole 72, and vertical hole 71 is opened on the outer ring installation base surface 9, and cross-drilled hole 72 1 ends and vertical hole 71 are connected, and cross-drilled hole 72 the other ends are connected with outer raceway 61.
Offer the uneven outer ring mounting hole 8 that distributes on the outer ring installation base surface 9, the center of circle, top of the vertical center of circle, 71 top, hole and outer ring mounting hole 8 is on same circumference, when inner ring 2 did not have enough spaces, pivoting support still can be processed oilhole and oiling easily easily.
Offer 11 outer ring mounting holes 8 on the outer ring installation base surface 9, wherein to concentrate and to be distributed in drift angle be on 50 ° the fan-shaped circular arc in the center of circle, top of 6 outer ring mounting holes 8, all the other 5 dispersed distribution are on remaining circular arc, make a side of pivoting support can bear the bigger power of tumbling, be more suitable for engineering machinery such as Hoisting Machinery.
