Therefore need rotation axis seal structure of the prior art to improve, to solve the defect of existing sealing configuration.
Summary of the invention
In view of this, the object of this invention is to provide a kind of oil collection ring for rotation shaft, it can solve the shortcomings such as in existing rotation shaft seal, sealing effect is poor, Sealing bearing capacity is poor, manufacture cost is high.
Oil collection ring for rotation shaft of the present invention, comprise flange, the oil-collecting ring wall of the axle sleeve coordinating with running shaft and adpting flange and axle sleeve, the inner cylindrical surface middle part of axle sleeve is along being circumferentially provided with ring decompression groove, on axle sleeve inner cylindrical surface between ring decompression groove and axle sleeve oil inlet end, be provided with the first annular oil sealing groove, on oil-collecting ring wall, be provided with the oil-collecting cavity being communicated with ring decompression groove, on sleeve outer circle cylinder between ring decompression groove and axle sleeve oil inlet end, be provided with a ligulate isolating plate, ligulate isolating plate extends into oil-collecting cavity and is divided into the second oil-collecting point chamber that the first oil-collecting point chamber that oral area communicates with the oil storage cavity of axle sleeve oil inlet end and oral area communicate with ring decompression groove, the first oil-collecting point chamber and the second oil-collecting divide bottom, chamber to be communicated with formation connecting vessels structure.
Further, on the axle sleeve inner cylindrical surface between ring decompression groove and axle sleeve oil outlet end, be provided with the second annular oil sealing groove;
Further, oil collection ring for rotation shaft is connected to form by link by two semi-rings;
Further, described link is bolt and nut component.
Beneficial effect of the present invention:
1, this oil collection ring for rotation shaft, its first annular oil sealing slot part can form one deck pressure film, to stop lubricating oil leakage.
The oil-collecting cavity of the connecting vessels structural formula that 2, this oil collection ring for rotation shaft arranges is under oil storage state, the oil storage cavity of ring decompression groove and axle sleeve oil inlet end is isolated mutually, pressure decreased from the machine oil of the first annular oil sealing groove end leakage enters ring decompression groove, post-decompression machine oil just flows into machine oil cavity, thereby can prevent lubricating oil leakage; And under the machine oil in machine oil cavity intercepts, the oil gas in the oil storage cavity of axle sleeve oil inlet end can not enter ring decompression groove, and then leaks from axle sleeve oil outlet end.
3, this oil collection ring for rotation shaft, the second annular oil sealing groove of its setting forms pressure film, can play the effect of auxiliary leakproof, can further prevent lubricating oil leakage, and can blocks air, to avoid airborne deleterious particle to damage running shaft.
4, this oil collection ring for rotation shaft is rigid construction, and bearing capacity is strong; And one-piece element is few, simple in structure, low cost of manufacture.
5, this oil collection ring for rotation shaft is split-type structural, easy to assembly.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the plan view of this oil collection ring for rotation shaft;
Fig. 2 is the sectional view of Fig. 1 along A-A;
Fig. 3 is the zoomed-in view of P portion in Fig. 2.
Embodiment
Fig. 1 is the plan view of this oil collection ring for rotation shaft; Fig. 2 is the sectional view of Fig. 1 along A-A; Fig. 3 is the zoomed-in view of P portion in Fig. 2.
As shown in the figure, the present embodiment oil collection ring for rotation shaft, comprise flange 1, the axle sleeve 2 coordinating with running shaft and the oil-collecting ring wall 3 of adpting flange and axle sleeve, the inner cylindrical surface middle part of axle sleeve 2 is along being circumferentially provided with ring decompression groove 4, on axle sleeve inner cylindrical surface between ring decompression groove 4 and axle sleeve oil inlet end, be provided with the first annular oil sealing groove 5, on oil-collecting ring wall, be provided with the oil-collecting cavity being communicated with ring decompression groove 4, on sleeve outer circle cylinder between ring decompression groove 4 and axle sleeve oil inlet end, be provided with a ligulate isolating plate 6, ligulate isolating plate 6 extends into oil-collecting cavity and is divided into the second oil-collecting point chamber 8 that the first oil-collecting point chamber 7 that oral area communicates with the oil storage cavity of axle sleeve oil inlet end and oral area communicate with ring decompression groove 4, the first oil-collecting point chamber 7 and the second oil-collecting divide 8 bottoms, chamber to be communicated with formation connecting vessels structure.
This oil collection ring for rotation shaft, when work, its first annular oil sealing slot part can form one deck pressure film, and to stop lubricating oil leakage, pressure film also can play lubrication, to reduce the wearing and tearing of running shaft.The oil-collecting cavity of the connecting vessels structural formula that this oil collection ring for rotation shaft arranges is under oil storage state, the oil storage cavity of ring decompression groove and axle sleeve oil inlet end is isolated mutually, pressure decreased from the machine oil of the first annular oil sealing groove end leakage enters ring decompression groove, post-decompression machine oil just flows into machine oil cavity, thereby can prevent lubricating oil leakage; And under the machine oil in machine oil cavity intercepts, the oil gas in the oil storage cavity of axle sleeve oil inlet end can not enter ring decompression groove, can prevent that oil gas from recoiling into ring decompression groove generation leakage.
As the improvement to the present embodiment, on the axle sleeve inner cylindrical surface between ring decompression groove 4 and axle sleeve oil outlet end, be provided with the second annular oil sealing groove 9; The second annular oil sealing groove forms pressure film, can play the effect of auxiliary leakproof, can further prevent lubricating oil leakage, and can blocks air, to avoid airborne deleterious particle to damage running shaft.
As the improvement to the present embodiment, oil collection ring for rotation shaft is connected to form by link 10 by two semi-rings, and the link in the present embodiment is bolt and nut component.The present embodiment oil collection ring for rotation shaft is split-type structural, and assembling is limited still less by revolute axes configuration compared with monolithic construction, and application area is wider, as it can be applicable to the sealing of crankshaft-flywheel end.Certainly in concrete enforcement, link 10 can also be other structures such as screw, rivet, pin, but mode with bolts is simpler, easy to assembly.
Finally explanation is, above embodiment is only unrestricted in order to technological scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technological scheme of the present invention, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
