Description
Technical field
The utility model relates to a kind of bearing lubrication structure, particularly a kind of large carrier bearing five-way lubricating structure.
Background technique
Pivoting support is a kind of large size bearing that can bear combined load, can bear simultaneously larger axially, radial load and tilting moment.It has the formations such as Internal and external cycle, rolling element, pivoting support is applied very extensive in real industry, by people, be called: " joint of machine " is between two articles, to need to do relative rotation motion, need again to bear the necessary important transmission part of machinery of axial force, radial force, tilting moment simultaneously.Pivoting support is widely used in industries such as ship equipment, engineering machinery, light industry and machinery, metallurgical machinery, medical machinery, industrial machineries.
Along with developing rapidly of machinery industry, its various performance requirements to bearing are also more and more higher, the large carrier bearing of various many raceways is thereupon raw, for different bearing structures, its lubricating structure is also different, through retrieval, does not find the large bearing capacity pivoting support lubricating structure identical with the utility model.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of large carrier bearing five-way lubricating structure of high lubricating effect.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of large carrier bearing five-way lubricating structure, comprise seat ring, upper blowout patche, lower blowout patche and cylinder rolling element, on seat ring, be evenly drilled with the seat ring mounting hole that distributes ringwise and connect the upper and lower end face of seat ring, the inner side surface of seat ring is an annular protrusion structure; Between upper blowout patche and the annular protrusion of seat ring, form raceway in twice, between lower blowout patche and seat ring, form raceway under twice, between the annular protrusion side of seat ring and the outer side surface of upper and lower blowout patche, form one and sidewinder; Described upper and lower, place cylinder rolling element in sidewindering; Its innovative point is: on described seat ring, be drilled with the sprue of a substantially horizontal, this sprue extends sidewindering of seat ring inner side surface place always; Also comprise four secondary flow roads, road, the inner in described four secondary flow roads, road is communicated with sprue, the outer end in described the first secondary flow road extends to the upper raceway bottom in outside, the outer end in the second secondary flow road extends to the upper raceway bottom of inner side, the outer end in the 3rd secondary flow road extends to the lower raceway place in outside, and the outer end in the 4th secondary flow road extends to the lower raceway place of inner side; And the inner in described the first secondary flow road, the second secondary flow road, the 3rd secondary flow road and the 4th secondary flow road is certainly arranged in order outside to inside on sprue; The end bottom of described sprue is provided with choked flow step; On the seat ring at place, described sprue outer end, of a grease fuel filler neck is set, described lubricating grease fuel filler neck is threaded with seat ring.
Further, described first and third secondary flow road is vertical run, and the second secondary flow road is the runner being tilted to, and the 4th secondary flow road is the runner under being tilted to.
The utility model has the advantage of: adopt sprue centralized oil supply, by four secondary channels, be communicated with respectively the oil lubrication that supplies that realizes raceway with upper and lower raceway; Secondary flow road is arranged in order on sprue, makes raceway preferentially and lower raceway fuel feeding, and adopts choked flow step to stop the direct approaching side raceway of lubricant oil at sprue end, and whole lubricating structure fuel feeding is more even, guarantees the normal operation of bearing.
Accompanying drawing explanation
Fig. 1 is the large carrier bearing five-way of the utility model lubricating structure schematic diagram.
Fig. 2 is partial enlarged drawing A in Fig. 1.
Embodiment
As shown in Figure 1, 2, comprise seat ring 1, upper blowout patche 2, lower blowout patche 3 and cylinder rolling element.
On seat ring 1, be evenly drilled with the seat ring mounting hole 4 that distributes ringwise and connect seat ring 1 upper and lower end face, the inner side surface of seat ring 1 is an annular protrusion structure.
