Description of drawings
The present invention is further detailed explanation below in conjunction with accompanying drawing.
Fig. 1 is that master of the present invention looks cross-sectional view.
Embodiment
A kind of Split solid dust mechanical shaft seal system, as shown in Figure 1, comprise the shaft seal gland 2 that is installed on the machine casing, between gland 2 and the box sealing face Tetrafluoro spacer 18 is being set, the inboard of gland center hole is arranging the multilayer lip seal circle 1 that contacts with rotating shaft sealing, in order to slow down dust to external leakage, through after a while running, lip seal can be than quick-wearing when aneroid is lubricated, after the wearing and tearing, produce micro-gap between lip seal and the axle, lip seal belongs to multilayer, can play the effect of labyrinth seal simultaneously.
It is poroid that the outside of gland center hole is ladder, rotating shaft in shoulder hole is being set with a sealing stationary ring 4 that is fixed together with gland, has an annular shoulder block on the outer peripheral surface of stationary ring 4, between the middle part end face in annular shoulder block and the shoulder hole O RunddichtringO 17 is being set, is leaving the gap between the interior edge face of stationary ring 4 interior edge faces and shoulder hole and also link to each other by horizontally disposed stop pin 3.
In the rotating shaft in stationary ring 4 outsides, be set with successively fixedly ring seat 11 of a rotating ring 6, retainer 8 and, linking to each other and synchronously rotation by pin 21,9 respectively between this three.
Fixedly ring seat 11 is fixed together by screw and rotating shaft.Be symmetrical arranged in the fixing lateral part of ring seat 11 at least two with the perpendicular through hole of rotating shaft, be separately installed with screw in the through hole, tighten screw so that fixedly ring seat rotate synchronously with rotating shaft.Fixedly arranging on the ring seat inner circle wall and the contacted O RunddichtringO 10 of rotating shaft.
Has an annular groove near in the fixedly ring seat 11 of gland, retainer 8 engage sleeves are contained in the annular groove, between the fixedly ring seat interior edge face of close gland and the rotating ring periphery wall annular shoulder block O RunddichtringO 7 is being set, fixedly ring seat 11 and rotating ring 6 engage sleeves are contained in the stationary gland 12, fixedly ring seat 11, retainer 8, rotating ring 6, stationary ring 4 and stationary gland 12 are made of the two halves body respectively, between the two halves body respectively by linking to each other with perpendicular pin and the bolt of rotating shaft.Namely, link to each other by pin 16 between the two halves body of stationary ring 4, link to each other by pin 5 between the two halves body of rotating ring 6, fixedly link to each other by pin 13 between the two halves body of ring seat 11, link to each other by pin 20 and bolt 19 between the two halves body of stationary gland 12.
On rotating ring 6 contacted stationary ring 4 end faces lubricated anti-abrasion structure is being set.Said lubricated anti-abrasion structure is arranging lubricant grease or oiling agent in the exterior edge face of stationary ring annular groove or blind hole uniformly at intervals to be set in annular groove or the blind hole.
Leave the gap between the relative end face of retainer 8 and fixing ring seat 11, have respectively a blind hole on the retainer coaxial end face relative with fixing ring seat, counterbalance spring 14 is housed between the blind hole.
Be coned face near fitting surface relative between the retainer of gland annular shoulder block interior edge face and the close retaining ring seat ring connected in star interior edge face of gland, the normal of this coned face and the angle between the vertical line are 15 °.
In the stationary gland middle part annular groove is being set, fixedly the middle part periphery wall engage sleeves of ring seat 11 is contained in this annular groove.
In installation process, retainer 8 will with fixing ring seat 11 as one, should conveniently install and reach again the design compensation stroke, therefore retainer 8 cooperates with fixing 15 ° of oblique angles of ring seat 11 employings, position with spacing, guaranteed that simultaneously retainer 8 and fixing ring seat 11 are integrated in assembling process.Fixedly adopt O type circle 10 to seal between ring seat 11 and the axle, and not in the sealing of retainer 8 and rotating ring 6 designs with axle, the equilibrant force of spring 14 is all acted on the retainer 8, thereby make rotating ring 6 and stationary ring 4 end faces be in closed state.Fixing ring seat 11 except have pin 13 fixing, designed again stationary gland 12 and adopted bolt 19 to connect two-part of subdivision, guarantee the hidden danger that in running, can not occur coming off.The structure of all subdivisions has all adopted the pin connection, can guarantee the concentricity of package unit, can not affect because of the accumulative total of machining error installation.
