Pivoting support is the nearly 40 years novel mechanical component worldwide risen gradually, and widely use in engineering machinery, it has the formation such as Internal and external cycle, rolling element.Along with developing rapidly of engineering machinery, it is also more and more higher to the various performance requirements of bearing, and the large carrier bearing of various many raceways is thereupon raw, for different bearing structures, its lubricating structure is also different, does not find the large bearing capacity pivoting support lubricating structure identical with the present invention through retrieval.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of engineering machinery pivoting support lubricating structure of high lubricating effect.
For solving the problems of the technologies described above, technological scheme of the present invention is: a kind of engineering machinery pivoting support lubricating structure, comprise seat ring, upper blowout patche, lower blowout patche and cylinder rolling element, seat ring is evenly drilled with distribution ringwise and the seat ring mounting hole of the upper and lower end face of through seat ring; Form raceway in twice between upper blowout patche and seat ring, form raceway under twice between blowout patche and seat ring down, form one between the outer side surface of seat ring side and upper and lower blowout patche and sidewinder; Described upper and lower, sidewinder in place cylinder rolling element; Its innovative point is: also comprise lower sprue, lower branch flow passage, upper sprue and upper branch flow passage, and upper and lower sprue is the horizontal run that internal diameter is identical, and wherein, lower sprue extends to sidewindering of seat ring madial wall place along the outer side wall of seat ring always; Lower branch flow passage is the vertical run that two-way internal diameter is identical, and the inner of twice branch flow passages is communicated with lower sprue, and outer end extends perpendicularly to the seat ring lower end surface at lower sprue place; Upper sprue extends to the madial wall of seat ring but not through seat ring outside seat ring; Upper branch flow passage is the vertical run that two-way internal diameter is identical, and on two, the inner of branch flow passage is communicated with upper sprue, and outer end extends perpendicularly to bottom raceway; Described upper and lower branch flow passage is arranging lead angle with the intersection of upper and lower sprue respectively, and the seat ring at described upper and lower sprue outer end place arranges of a grease fuel filler neck respectively.
Further, the upper and lower branch flow passage outside described seat circle and the lead angle between upper and lower sprue are small fillet, the diameter D of described small fillet
little=0.8D ~ D, wherein, D is the diameter of upper and lower sprue; Upper and lower branch flow passage inside described seat circle and the lead angle between upper and lower sprue are large lead angle, the diameter D of described large lead angle
little=1.5D ~ 2D, wherein, D is the diameter of upper and lower sprue.
The invention has the advantages that: in utilization, upper raceway fuel feeding is carried out in sprue and the cooperation of upper branch flow passage, lower sprue and lower branch flow passage coordinate the fuel feeding carrying out lower raceway and sidewinder, and in the branch flow passage of rear side, adopt large lead angle structure simultaneously, the branch flow passage fuel delivery of side before and after sprue is reached unanimity, after tested, adopt this kind of structure to be each raceway fuel feeding, the delivery volume difference of each raceway lubricating grease is no more than 15%, whole lubricating structure fuel feeding is more even, guarantees the normal operation of bearing.
Accompanying drawing explanation
Fig. 1 is engineering machinery pivoting support lubricating structure schematic diagram in the present invention.
Fig. 2 is partial enlarged drawing A in Fig. 1.
Embodiment
As shown in Figure 1, 2, seat ring 1, upper blowout patche 2, lower blowout patche 3 and cylinder rolling element is comprised.
