Abstract
The utility model relates to a sealing structure mounted between two bonding surfaces of a hydraulic device, which comprises a first bonding surface (2) positioned on a first member (1) and a second bonding surface (4) positioned on a second member (3), wherein a ring-shaped groove (5) is formed on the first bonding surface (2), a seal ring (6) and a Glyd ring (7) are arranged inside the ring-shaped groove, and the seal ring is positioned inside the Glyd ring. The sealing structure is characterized in that an inner notch (8) is arranged on the inner circumference of the Glyd ring (7) and fits well with the outer circumference of the seal ring (6), and the inner notch (8) is in contact with the outer circumference of the seal ring (6) under the condition that the first bonding surface (2) and the second bonding surface (4) are bonded. The sealing structure increases the contact area between the seal ring and the inner circumference of the Glyd ring, which is equivalent to the surface-to-surface contact, so that the space required for the deformation of the seal ring is reduced, the excessive deformation of the seal ring is effectively prevented, and better effect of preventing the seal ring from creeping is achieved. Therefore, the sealing effect between the two bonding surfaces in the hydraulic device can be improved.
Description
Technical field
The utility model relates to a kind of sealing configuration, relates in particular to the sealing configuration between the two junction in a kind of hydraulic pressure installation.
Background technique
Generally all need between the junction plane of two parts in the hydraulic pressure installation to be tightly connected, to prevent leaking outside of hydraulic oil or other hydraulic medium.Oil hydraulic motor is a kind of comparatively common hydraulic pressure installation, as a patent No. is a kind of hydraulic motor structure so the Chinese utility model patent " novel crankshaft connecting rod type oil hydraulic motor " of ZL200620105571.2 (notification number is CN2924112Y) has disclosed, it generally includes logical food tray, oil distribution casing, housing, the plunger bushing that is connected with housing seal, capping and crankshaft group and a plurality of plunger connecting rod assembly, logical food tray is by being bolted on the housing, oil distribution casing is between logical food tray and housing, the one end is relative with logical food tray, the other end is connected with an end of bent axle by the double end key, and oil distribution casing and bent axle are rotated synchronously.
The following sealing configuration of general employing between the junction plane of two parts in the existing hydraulic pressure installation, be example explanation sealing configuration now with the junction plane between oil hydraulic motor middle shell and the plunger bushing, on the junction plane of housing, have annular groove 1 ', be placed with seal ring 2 ' and Glais ring 3 ' in this annular groove, as shown in Figure 3, to form liquid sealing between the junction plane to plunger bushing and housing, seal ring is positioned at Glais ring, be provided with that Glais ring can make seal ring not have to creep, wear-resistant, long service life, make between the two junction dynamic and static sealing effect splendid.
The inner and outer circumferential surfaces of existing Glais ring is the plane, the outer circumferential face of seal ring then is a cambered surface, after the two junction sealing is installed, the area of contact of seal ring and Glais ring is less, be equivalent to the contact of line face, seal ring also has bigger deformation space like this, and the possibility that seal ring is creeped in addition is so the structure of existing seal ring and Glais ring also can be further improved.
Summary of the invention
Technical problem to be solved in the utility model is that the sealing configuration between the two junction in a kind of hydraulic pressure installation that can increase seal ring and Glais ring area of contact is provided at above-mentioned prior art present situation, the sealing structure can further make seal ring not yielding, the anti-seal circle better effects if of creeping.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: the sealing configuration in a kind of hydraulic pressure installation between the two junction, comprise first junction plane that is positioned on first parts and second junction plane on second parts, wherein, have annular groove on first junction plane, be placed with seal ring and Glais ring in this annular groove, seal ring is positioned at Glais ring, it is characterized in that: have the inner recess that matches with the seal ring outer circumferential face on the inner peripheral surface of described Glais ring, under first junction plane and the second junction plane bonding state, described inner recess contacts with the seal ring outer circumferential face.
Above-mentioned inner recess is symmetrical arranged along the medial axis on the Glais ring thickness direction.This structure makes the wall thickness symmetry of lower edge on the inner recess, can prevent that the last lower edge of the inner recess of Glais ring from because of unbalance stress the bad situation generation of sealing effect that irregular deformation finally causes taking place.
Compared with prior art, advantage of the present utility model is: under first junction plane and the second junction plane bonding state, inner recess contacts with the seal ring outer circumferential face, increased the area of contact between seal ring and the Glais ring inner peripheral surface, it is the equal of the contact of face face, has reduced the deformation space of seal ring, effectively prevents the deformation that seal ring is excessive, the anti-seal circle better effects if of creeping, just the sealing structure can improve the sealing effect between the two junction in the hydraulic pressure installation.

Fig. 3 is the sealing configuration between the two junction in the hydraulic pressure installation of background technique.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, 2, be specific embodiment of the utility model.
Sealing configuration in a kind of hydraulic pressure installation between the two junction, comprise first junction plane 2 that is positioned on first parts 1 and second junction plane 4 on second parts 3, wherein, have annular groove 5 on first junction plane 2, be placed with seal ring 6 and Glais ring 7 in this annular groove 5, seal ring 6 is positioned at Glais ring 7, has the inner recess 8 that matches with seal ring 6 outer circumferential faces on the inner peripheral surface of Glais ring 7, this inner recess 8 distributes along the inner peripheral surface of Glais ring 7, under first junction plane 2 and second junction plane, 4 bonding states, described inner recess 8 contacts with seal ring 6 outer circumferential faces.
The sealing structure is mainly used in to be needed in the hydraulic pressure installation to reach between the various junction planes of liquid sealing standard.
Claims (2)
1. the sealing configuration between the two junction in the hydraulic pressure installation, comprise first junction plane (2) that is positioned on first parts (1) and second junction plane (4) on second parts (3), wherein, have annular groove (5) on first junction plane (2), be placed with seal ring (6) and Glais ring (7) in this annular groove (5), seal ring (6) is positioned at Glais ring (7), it is characterized in that: have the inner recess (8) that matches with seal ring (6) outer circumferential face on the inner peripheral surface of described Glais ring (7), under first junction plane (2) and second junction plane (4) bonding state, described inner recess (8) contacts with seal ring (6) outer circumferential face.
