Abstract
The utility model provides a kind of pressurized machine seal ring, comprise a ring body, ring body has a port, the both sides of port are the first joint and second joint of ring body, its improvements are: the fitting surface of the first joint comprises first and faces directly, face directly connect and the first inclined-plane extended to the oblique below deviating from the second joint direction with first, connect with the first inclined-plane and face directly to second of downward-extension; The fitting surface of the second joint and the fitting surface each several part corresponding matching of the first joint, comprise the 3rd and face directly, faces directly and connect and the second inclined-plane extended to the oblique below in the first joint direction, connect and face directly to the 4th of downward-extension with the second inclined-plane with the 3rd.The port of seal ring add face directly, the combination on inclined-plane and the step of formation, lubricant oil produces flow resistance when seal ring port flows, and seal ring port can stop the mobility of lubricant oil.Seal ring axial seal better effects if after improvement, solves the problem of pressurized machine leakage of oil.
Description
Technical field
The utility model relates to engine supercharger art, especially a kind of shaped end seal ring for pressurized machine.
Background technique
Automobile booster is applied in motor car engine at present more and more, and pressurized machine can play for petrol engine or diesel engine and improve power and moment of torsion, reduces the beneficial effect of discharge.
Pressurized machine leakage of oil is that pressurized machine lost efficacy modal phenomenon, as depicted in figs. 1 and 2, port is straight mouth to current seal ring structure, and seal ring is placed in bearing support (also referred to as intermediate), for axial seal, be all provided with seal ring in the turbine end of turbosupercharger and pressure side.But the sealing effect of the seal ring of this kind of structure is not best, after using after a while, the axial oil leakage phenomenon of easy generation, if there is leakage of oil (lubricant oil spills) in the turbine end of turbosupercharger (hot junction), then lubricant oil can enter engine exhaust pipe, if leakage of oil occurs the pressure side of turbosupercharger (cold junction), then lubricant oil can enter engine air inlet tube.
Summary of the invention
For the deficiencies in the prior art, the utility model provides the pressurized machine seal ring after a kind of improvement, and the shape for pressurized ring port is improved, and the axial seal effect of seal ring is strengthened greatly, solves the problem of pressurized machine leakage of oil.The technical solution adopted in the utility model is:
A kind of pressurized machine seal ring, comprise a ring body, ring body has a port, the both sides of port are the first joint and second joint of ring body, and its improvements are:
The fitting surface of the first joint comprises first and faces directly, faces directly and connects and the first inclined-plane extended to the oblique below deviating from the second joint direction, connect and face directly to second of downward-extension with the first inclined-plane with first;
The fitting surface of the second joint and the fitting surface each several part corresponding matching of the first joint, comprise the 3rd and face directly, faces directly and connect and the second inclined-plane extended to the oblique below in the first joint direction, connect and face directly to the 4th of downward-extension with the second inclined-plane with the 3rd.
Further, the first inclined-plane is identical with the angle of inclination on the second inclined-plane.
Preferably, the angle of inclination on the first inclined-plane and the second inclined-plane is 25 degree ~ 60 degree.
The utility model has the advantage of: the port of seal ring add face directly, the combination on inclined-plane and the step of formation, lubricant oil is not easy the small labyrinth gap leaking through seal ring in the axial direction, lubricant oil produces flow resistance when seal ring port flows, till lubricant oil can not flow, thus eliminate the problem of booster turbine end, pressure side sealing place leakage of oil.Seal ring axial seal better effects if after improvement, solves the problem of pressurized machine leakage of oil.
Accompanying drawing explanation
Fig. 1 is existing seal ring plan view.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is port of the present utility model plan view.
Fig. 4 is plan view of the present utility model.
Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
Existing seal ring structure as depicted in figs. 1 and 2, comprises a ring body, ring body has a port one, port one is straight mouth, the fitting surface that first joint 2 of port one both sides is relative with the second joint 3, two sides that namely the first joint 2 is relative with the second joint 3, all face directly.Therefore the axial seal effect of seal ring is general.
It is the seal ring of the improvement that the utility model proposes shown in Fig. 3 and Fig. 4.It is the radially-outer surface of seal ring near ports shown in Fig. 3.The main improvement of seal ring is the shape of port one.
The both sides of port one are the first joint 2 and the second joint 3 of ring body;
The fitting surface of the first joint 2 comprises first and faces 21 directly, faces 21 directly and connects and the first inclined-plane 22 extended to the oblique below deviating from the second joint 3 direction, connect and face 23 directly to second of downward-extension with the first inclined-plane 22 with first;
The fitting surface of the second joint 3 and the fitting surface each several part corresponding matching of the first joint 2, comprise the 3rd and face 31 directly, face 31 directly connect and the second inclined-plane 32 extended to the oblique below in the first joint 2 direction with the 3rd, connect with the second inclined-plane 32 and face 33 directly to the 4th of downward-extension.
Wherein the first inclined-plane 22 is identical with the angle of inclination on the second inclined-plane 32, and angle of inclination is preferably 25 degree ~ 60 degree.
Above-mentionedly face the face referring to the radial direction being parallel to seal ring directly, plane of structure refers to the face being parallel to seal ring circumferencial direction.
Sealing ring is assemblied in bearing support, axially setting a rational seal ring, the port one of seal ring adds to be faced directly, the combination on inclined-plane and the step of formation, and coordinate a rational port gap, the gap of port one is controlled in 2 ~ 4 (1 is 0.01mm), lubricant oil produces flow resistance when seal ring port flows, seal ring port can stop the mobility of lubricant oil, till lubricant oil can not flow, lubricant oil in bearing support (also referred to as intermediate) can not be revealed, thus eliminate booster turbine end, the problem of pressure side sealing place leakage of oil.Therefore the seal ring axial seal better effects if after improving.
