Abstract

The utility model discloses an oil collection ring with a seepage prevention function. The oil collection ring comprises a rotor (2), a stator (1), a rotary seal ring (6), a guide strip (7), a lining (3), a shaft (4) and an end cover (5), wherein the stator (1) penetrates into the rotor and is axially and fixedly connected with the rotor (2) through the shaft (4), the lining (3) and the end cover (5); and the oil collection ring can rotate around a rotation central axis at an angle of 360 degrees, and the shaft (4) is taken as the rotation central axis. The design of a pore channel on the stator (1) of the oil collection ring can guarantee that a small amount of oil directly enters an oil collection oil passage and is collected into an oil tank through the oil passage after being seeped to the outer side of a working oil chamber of the oil collection ring, so that the environmental pollution can be reduced to the minimum level.

Description

A kind of remittance oil ring with leakage proof function
Technical field
The present invention relates to a kind of remittance oil ring, particularly a kind of remittance oil ring with leakage proof function.
Background technique
The oil ring that converges is to be applied in a kind of element comparatively common in the hydraulic system, and it can be used as the pipeline connection, and can be rotated motion around running shaft, remains correct that oil circuit is communicated with in movement process, is widely used in engineering machinery.The general oil ring that converges is made up of rotor, stator, Sealing, stator and rotor coaxial assembling, and stator penetrates in the rotor, by running shaft stator and rotor axial is connected firmly, and stator and rotor can be done relative rotary motion around running shaft.Stator is fixing not to move, and rotor is by the driving shaft driven rotary.Stator and epitrochanterian oilhole are in relation one to one all the time in rotary course, guarantee the accurate connection of oil circuit.Because the oil ring that converges is to rotatablely move, for avoiding occurring joule effect, Sealing is had relatively high expectations in rubbing surface part hardness, and is wear-resisting, wear-resistant, certainly will will sacrifice certain sealability like this.So general remittance oil ring in use the seepage situation can occur.Seepage can cause bigger pollution to environment on the one hand, on the other hand, can bring the luxus consumption of medium, has improved the operating cost of equipment.
The model utility content
The utility model discloses a kind of remittance oil ring, solve general remittance oil ring and in use leakage problems can occur with leakage proof function.
A kind of remittance oil ring with leakage proof function, comprising: rotor, stator, rotating seal ring also comprise: guidance tape, lining, axle, end cap.A plurality of axial blind holes, circular groove and radial hole are arranged on the stator, the center of circle of axial blind hole be distributed in the coaxial circumference of the spin axis of shaft parts on, each circular groove and radial hole are positioned at the terminal position of corresponding axial blind hole, each radial hole is communicated with the arc-shaped surface of circular groove, o-ring groove is arranged between the circular groove, and rotating seal ring places o-ring groove.There is oil duct at the two ends of stator oil groove, and there is rotating seal ring at the two ends of oil duct.There is guidance tape in the outside of all rotating seal rings.One end of axle is " one " word groove structure, and the other end is a square structure.Lining is enclosed within the stator center hole, and axle places the center hole of lining and stator, and an end of axle square structure places in the end cap, and the bond structure on the end cap excircle embeds in the end face groove of rotor.End cap is connected with the rotor screw, and end cap, axle, lining, stator are successively by card key axial restraint.
When the driving shaft that rotatablely moves rotates, " one " word troughed belt moving axis by axle head together rotates, the rotation of axle drives end cap by square structure and rotates jointly, to be rotatablely moved by the bond structure between end cap and the rotor is delivered on the rotor again, and rotor can be done rotatablely moving with respect to stator with the driving shaft that rotatablely moves like this.Stator connects firmly with the pedestal that does not move.Because the degree of depth difference of the axial blind hole of processing on the stator, the circular groove on the stator, respectively with rotor on the radial blind holes of diverse location be interconnected, make rotor rotation can be communicated with all the time with unique duct on the stator to any position.The effect of guidance tape be converge oil ring can support rotor when rotating, guarantee that rotating seal ring is stressed evenly, when the oil ring level of especially converging is installed, if there is not guidance tape, because the effect of gravity, rotor can push rotating seal ring, makes rotating seal ring discontinuity on circumference, cause concentrated wear, lost efficacy fast.When converging oil ring work, even have micro-fluid to leak into to converge the outside of oil ring working oil chamber, also will directly enter fluid and collect oil duct, and collect oil sump tank by oil duct and can not form and exosmose.
The present invention has remarkable result to aspects such as environmental protection, saving cost and equipment operation safety.

Embodiment
A kind of remittance oil ring with leakage proof function comprises: rotor 2, stator 1, rotating seal ring 6 also comprise: guidance tape 7, lining 3, axle 4, end cap 5.Axial blind hole, circular groove and radial hole are arranged on the stator 1, the center of circle of axial blind hole be distributed in the coaxial circumference of the spin axis of shaft parts 4 on, each circular groove and radial hole are positioned at the terminal position of corresponding axial blind hole, each radial hole is communicated with the arc-shaped surface of circular groove, o-ring groove is arranged between the circular groove, and rotating seal ring 6 places o-ring groove.There is oil duct at the two ends of stator 1 oil groove, and there is rotating seal ring 6 at the two ends of oil duct.There is guidance tape 7 in the outside of all rotating seal rings 6.One end of axle 4 is " one " word groove structure, and the other end is a square structure.Lining 3 is enclosed within stator 1 center hole, and axle 4 places the center hole of lining 3 and stator 1, and an end of axle 4 square structures places in the end cap 5, and the bond structure on end cap 5 excircles embeds in the end face groove of rotor 2.End cap 5 is connected with rotor 2 screws, and end cap 2, axle 4, lining 3, stator 1 are successively by card key axial restraint.
When the driving shaft that rotatablely moves rotates, " one " word troughed belt moving axis by axle 4 ends together rotates, the rotation of axle 4 drives end cap 5 by square structure and rotates jointly, to be rotatablely moved by the bond structure between end cap 5 and the rotor 2 is delivered on the rotor 2 again, and rotor 2 can be done rotatablely moving with respect to stator 1 with the driving shaft that rotatablely moves like this.Stator 1 connects firmly with the pedestal that does not move.Because the degree of depth difference of the axial blind hole of processing on the stator 1, the circular groove on the stator 1 can be interconnected with the radial blind holes of diverse location on the rotor 2 respectively, and making rotor 2 turn to the arbitrary position can be communicated with all the time with unique duct on the stator 1.The effect of guidance tape 7 is support rotor 2 when converging the oil ring rotation, guarantee that rotating seal ring 6 is stressed even, when the oil ring level of especially converging is installed, if there is not guidance tape 7, because the effect of gravity, rotor 2 can push rotating seal ring 6, makes rotating seal ring 6 discontinuity on circumference, cause concentrated wear, lost efficacy fast.When converging oil ring work, even have micro-fluid to leak into to converge the outside of oil ring working oil chamber, also will directly enter fluid and collect oil duct, and collect oil sump tank by oil duct and can not form and exosmose.
