Abstract
The present invention relates to a kind of large carrier bearing lubricating structure, comprise seat ring, upper blowout patche, lower blowout patche and cylinder rolling element; Between upper blowout patche and seat ring, between lower blowout patche and seat ring, formed upper and lower respectively and sidewinder between the side of seat ring and the outer side surface of upper and lower blowout patche, the side of seat ring is drilled with a main oil gallery; Main oil gallery is also connected with branch flow passage and lower branch flow passage, lower branch flow passage axially extends downward the lower end surface of seat ring from position between twice raceways along seat ring; Upper branch flow passage extends axially up to the upper-end surface of seat ring from position between raceway two along seat ring, the both sides, top of upper branch flow passage arrange the oblique runner leading to upper raceway.The invention has the advantages that: lubrication oil supply is rational in infrastructure, guarantee the normal work of large carrier bearing, reduce wearing and tearing; Fuel filler neck is built in the cavity of seat ring, specious, installs without hindrance; Two oblique runner axially see V-shaped angle along seat ring, make lubricating grease by more smooth during oblique runner.
Description
Technical field
The present invention relates to a kind of bearing, particularly the large carrier bearing lubricating structure of one.
Background technique
Pivoting support is a kind of large size bearing that can bear combined load, can bear larger axial, radial load and tilting moment simultaneously.It has the formation such as Internal and external cycle, rolling element, pivoting support is applied very extensive in real industry, being called by people: " joint of machine ", is need between two articles to do relative rotation motion, needs again the necessary important transmission part of machinery simultaneously bearing axial force, radial force, tilting moment.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, 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 large carrier bearing 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 large carrier bearing 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, the inner side surface of seat ring is an annular protrusion structure; Form raceway in twice between upper blowout patche and the annular protrusion of seat ring, form raceway under twice between blowout patche and seat ring down, form one between the annular protrusion side of seat ring and the outer side surface of upper and lower blowout patche and sidewinder; Described upper and lower, sidewinder in place cylinder rolling element; Its innovative point is: the side of described seat ring is drilled with a main oil gallery extended along seat ring radial direction, and this main oil gallery extends to the bottom of sidewindering always; Main oil gallery is also connected with branch flow passage and lower branch flow passage, described lower branch flow passage axially extends downward the lower end surface of seat ring from position between twice raceways along seat ring; Described upper branch flow passage extends axially up to the upper-end surface of seat ring from position between raceway two along seat ring, the both sides, top of upper branch flow passage arrange oblique runner, this oblique runner extends to the sidewall of raceway on two, two oblique runner axially see V-shaped angle along seat ring, and described V-arrangement angle is 20-30 °; The top of upper branch flow passage is tapped hole A structure, and tapped hole A is equipped with bolt plug;
The seat ring sidewall of described main oil gallery outer end is provided with cavity, arranges concentric with main oil gallery and the tapped hole B be communicated with, tapped hole B are equipped with fuel filler neck bottom cavity.
The invention has the advantages that: carry out centralized oil supply by main oil gallery, lubricating grease is directly imported the lubrication realizing lower raceway between twice raceways by lower branch flow passage, lubricating grease is then imported in raceway by the oblique runner be communicated with upper raceway sidewall by upper branch flow passage, and then realizes the lubrication of upper raceway.Lubrication oil supply is rational in infrastructure, guarantees the normal work of large carrier bearing, reduces wearing and tearing; Fuel filler neck is built in the cavity of seat ring, specious, installs without hindrance; Two oblique runner axially see V-shaped angle along seat ring, make lubricating grease by more smooth during oblique runner.

Embodiment
As shown in Figure 1, 2, comprise seat ring 1, upper blowout patche 2, lower blowout patche 3 and cylinder rolling element,
Seat ring 1 is evenly drilled with distribution ringwise and the seat ring mounting hole 4 of the upper and lower end face of through seat ring 1, this seat ring mounting hole 4 is for being connected and fixed by bolt and bearing object, and the inner side surface of seat ring 1 is an annular protrusion structure.
Form raceway in twice between upper blowout patche 2 and the annular protrusion of seat ring 1, between lower blowout patche 3 and seat ring 1, form raceway under twice, form one between the outer side surface of the annular protrusion side of seat ring 1 and upper blowout patche 2, lower blowout patche 3 and sidewinder; Upper raceway, lower raceway, sidewinder in place cylinder rolling element 5,6,7 respectively.
The side of seat ring 1 is drilled with a main oil gallery 8 extended along seat ring 1 radial direction, and this main oil gallery 8 extends to the bottom of sidewindering always.
Main oil gallery 8 is also connected with branch flow passage 8a and lower branch flow passage 8b, lower branch flow passage 8b axially extends downward the lower end surface of seat ring 1 from position between twice raceways along seat ring 1.And upper branch flow passage 8a extends axially up to the upper-end surface of seat ring 1 from position between raceway two along seat ring 1, the top of upper branch flow passage 8a is tapped hole A structure, and tapped hole A is equipped with bolt plug 9.
The both sides, top of upper branch flow passage 8a arrange oblique runner 8c, and this oblique runner 8c extends to the sidewall of raceway on two, and as shown in Figure 3,4, two oblique runner axially see V-shaped angle along seat ring, and V-arrangement angle is 20-30 °.
The seat ring sidewall of outer 8 ends of main oil gallery is provided with cavity 10, and the tapped hole B that be communicated with, tapped hole B outfit fuel filler neck 11 concentric with main oil gallery is set bottom cavity 10.
