Abstract
The present invention discloses a machining method of an antirust conic sleeve oil hole used on large and medium size oil film bearings. A platform is milled on the slope of a taper sleeve flange 5 by an end milling cutter, and the platform is divided into N equal groups along the circumferential direction of the taper sleeve flange 5. An oil hole 9 is drilled on the platform with a drill in a direction which has an included angle alpha with the axial line of a taper sleeve 6 so that a through hole of the oil hole 9 is as close as possible to the root part of the taper sleeve flange 5, and then, the oil hole 9 is put into a small nozzle and is riveted tightly after the oil hole 9 is expanded. When an oil film bearing rotates at a high speed, oil liquid ejected from a pressurized oil film is pressurized into the oil hole 9 in a pressure of more than 0.4MPa. Under the action of inertial force and taper sleeve centrifugal force, the oil liquid which is radial in difference angles is ejected to different parts of a back cavity 4 or a back cavity 4' of the taper sleeve flange 5 so that the cavity has the advantages of no rust, no foam and no residue generation. Therefore, the service life of the oil film bearing is extended.
Description
Technical field
The present invention relates to a kind of processing method that is used for oil filler point on the antirust tapered sleeve of big-and-middle-sized filmatic bearing.
Background technology
Be applied to the tapered sleeve in the big-and-middle-sized filmatic bearing (fluid bearing that connects hole machine backing roll as the CSP sheet blank continuous casting) on the industrial production line at present, because the effect of tapered sleeve flange, the back cavity that is positioned at the tapered sleeve flange of oil back chamber generally is in no oil condition, because of unavoidable air pocket and moisture content in the hydraulic oil in its operating temperature (usually about 40 ℃ as inlet temperature, and can reach 50-60 ℃ through squeezing pressure oil film temperature) in vaporization easily, cause this cavity circumference corrosion.All pass through antirust processing (as baking vanish etc.) mostly for its parts of equipment from external introduction, so occupied the minority by the corrosion position, and the parts great majority of home equipment are not done antirust processing, after after a while, all can occur getting rusty, bubble and fall the slag phenomenon, even make have more than is needed how long (as one month) still have problem of rustiness to occur through antirust processing (as japanning etc.) again, its consequence is oxide that causes because of getting rusty and the oil that slag will have a strong impact on hydraulic oil of falling that contains paint, stop up the filter in the oil circuit, even the minute surface of sanding tapered sleeve, greatly influence service life of filmatic bearing.
Summary of the invention
The object of the present invention is to provide a kind of can prevent that oil film bearing conic sleeve back cavity from getting rusty, falling slag and on tapered sleeve oil orchid the method for processing oil filler point.
For achieving the above object, the technical solution used in the present invention is: at tapered sleeve flange back toward its root along the circumferential direction five equilibrium bore N group (N 〉=3) and be α angle (α=30-75 °) aperture.The method of processing this aperture is: the slotting cutter with ф 10～14 mills out a platform on the inclined-plane that the tapered sleeve flange need be holed, fluted drill with ф 6～10mm bores oil filler point toward be α angle tapered sleeve vertical line direction near tapered sleeve flange root again, then use the fluted drill reaming of ф 8-12mm, the reaming depth controlled is between 8～12mm, small nozzle with (ф 8～12) * (7～11) mm is encased in this hole again, then the openning with this hole rivets, drainage trough direction on this small nozzle is aimed at the tapered sleeve axis, and the aperture in the middle of the small nozzle is ф 1.5～2.5mm.
The antirust tapered sleeve that adopts the processing method of a kind of antirust tapered sleeve oil filler point that as above technical scheme provides to form is compared with the tapered sleeve of prior art, and its advantage is:
1. fundamentally solve the problem of rustiness of tapered sleeve back cavity, prolong 3～4 times of fluid bearing service lifes, can also prolong the operating period of hydraulic oil simultaneously;
2. this processing method also is applicable to the transformation of traditional tapered sleeve fully, can not influence the service life and the serviceability of tapered sleeve;
3. processing technology is simple, does not increase too many processing cost, is convenient to promote;
Description of drawings
Fig. 1 is employed oil film bearing conic sleeve structural representation;
Fig. 2 is the enlarged diagram at Fig. 1 indication A place, also is the Working position schematic diagram of oil filler point, also is specification digest accompanying drawing of the present invention.
Fig. 3 is the enlarged diagram at Fig. 2 B place.
The specific embodiment
Below in conjunction with drawings and Examples the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, lining 7 is installed in the bearing block 8, and tapered sleeve 6 is sleeved on lining 7 inside, and the overhang of tapered sleeve 6 limit portions is a tapered sleeve flange 5, and it is near lining 7.In the upper end of bearing block 8 bearing housing 2 is arranged, between tapered sleeve 6 and bearing housing 2, be equipped with tapered sleeve ring 3, conical bearing 1 is installed in the bearing housing 2, and between bearing housing 2, tapered sleeve ring 3, tapered sleeve 6 and bearing block 8, form cavity 4 and 4 ', tapered sleeve flange 5 be arranged in this cavity 4 or 4 '.Oil filler point 9 is just processed on tapered sleeve flange 5 (as shown in Figure 2).Its processing method is:
1. the circumference with tapered sleeve flange 5 is divided into N group 2N five equilibrium (N 〉=3), and fixed symmetry two is divided into one group;
2. the slotting cutter with ф 10-14mm mills out platform F-F ' on the back side of the equally divided position on the inclined-plane of tapered sleeve flange 5, and the vertical line of platform F-F ' becomes the α angle with the axis of tapered sleeve 6;
3. become α angle (α=30-75 °) direction on platform F-F ', to bore N with tapered sleeve 6 axis and organize oil filler point 9, and allow the perforation of oil filler point 9 be in the root of tapered sleeve flange 5, make the axis of the center line of oil filler point 9 towards tapered sleeve 6 with the fluted drill of ф 6-10mm;
4. the fluted drill of using ф 8～12mm is oil filler point 9 reamings, and the degree of depth of reaming is remained between 8～12mm;
5. ф (8～12) * (7～11) mm small nozzle 10 is encased in the oil filler point 9 and with its openning and rivets, prevent that small nozzle 10 from throwing away.Aperture 11 diameter ф 1.5～2.5mm in the small nozzle 10.
In use, because filmatic bearing is with very high-speed rotation, the fluid that penetrates from the pressure oil film will be to inject oil filler point 9 greater than the pressure of 0.4MPa, under its inertia and tapered sleeve action of centrifugal force, fluid is radial cavity 4 or the 4 ' different parts that is ejected into tapered sleeve flange 5 backs along oil filler point 9 with different angles, make cavity 4 or 4 ' have all the time hydraulic oil, under various working environments, can both guarantee cavity 4 or 4 ' middle non-corrosive, non-foaming, do not fall slag, guaranteed the service life of filmatic bearing.
