Abstract
The utility model relates to a seal component of a shaft, in particular to a dynamic ring mechanism of a mechanical seal device used for sealing both ends of a rotary shaft immersed in fluid. The dynamic ring mechanism comprises a floating seal ring and a transmission sleeve fixed on the shaft; an auxiliary shaft sleeve is arranged between the transmission sleeve and the shaft; the floating seal ring is nested on the auxiliary shaft sleeve. The dynamic ring mechanism has the advantages that the structure of the technical proposal is reasonable; the problem that the radial movement of the floating seal ring is influenced by the rusty (shaft or) shaft sleeve in the prior art is solved.
Description
Technical field:
The utility model relates to a kind of black box, relate in particular to a kind of rotating ring mechanism of the mechanical seal that the two ends that are immersed in the running shaft in the fluid are sealed.
Background technique:
Fluctuate hermetical ring in the traditional mechanical seal drive sleeve can endwisely slip on (axle or) axle sleeve of water pump, and its thrust by spring closely cooperates rotating ring and stationary ring.(axle or) axle sleeve is that ferrous metal is made because most of, and this material easily gets rusty in water.(axle or) axle sleeve has just increased the axially movable resistance of fluctuate hermetical ring after getting rusty, and when serious, spring is difficult to promote, and this has influenced the effect of sealing.
Summary of the invention:
The purpose of this utility model is exactly at the existing in prior technology deficiency, and a kind of technological scheme of mechanical seal device is provided, and this scenario-frame is reasonable, and having solved original (axle or) axle sleeve gets rusty influences the axially movable problem of fluctuate hermetical ring.
This programme is realized by following technical measures: comprise fluctuate hermetical ring and be fixed on drive sleeve on the axle between described drive sleeve and the axle auxiliary axle sleeve is arranged, fluctuate hermetical ring is sleeved on auxiliary axis and puts.
This programme adds the auxiliary axle sleeve that rust preventive material is made between drive sleeve (or transmission ring) and axle, solved the axially movable problem that original axial length rust influences fluctuate hermetical ring.The fluctuate hermetical ring of traditional mechanical sealing is contained on the axle, in a single day axle gets rusty, and moving axially of fluctuate hermetical ring is just very difficult, and when serious, spring is difficult to promote.This rust preventive material can be stainless steel.This fluctuate hermetical ring comprises O type circle, V-type ring, U type ring, Y x circle, tooth form ring etc.
If be set with axle sleeve on the described axle, this auxiliary axis is set between drive sleeve and the axle sleeve, has solved original axle sleeve and has got rusty and influence the axially movable problem of fluctuate hermetical ring, and fluctuate hermetical ring can put at auxiliary axis and move axially.
Described auxiliary axle sleeve and drive sleeve (or transmission ring) make or are made as one for one, can be convenient for assembly.
The beneficial effect of this programme can be learnt according to the narration to such scheme, owing in this scheme, between drive sleeve (or transmission ring) and (spool or) axle sleeve auxiliary axle sleeve is arranged, fluctuate hermetical ring can put at this auxiliary axis and endwisely slip, and no matter whether (axle or) axle sleeve gets rusty.This scheme can solve effectively fluctuate hermetical ring endwisely slip the difficulty problem, guaranteed closely cooperating of rotating ring and stationary ring.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure, 1 is axle, and 2 are the friction rotating ring, and 3 are the O type circle that floats, and 4 is apical ring, and 5 is spring, and 6 are auxiliary axle sleeve, and 7 is drive sleeve.
Embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by an embodiment.
By accompanying drawing as can be seen, the rotating ring mechanism of the mechanical seal of this programme, axle 1, friction rotating ring 2, float O type circle 3, apical ring 4, spring 5, drive sleeve 7 are arranged, in drive sleeve 7, spring 5, apical ring 4, unsteady O type circle 3 and friction rotating ring 2 are linked in sequence, drive sleeve 7 is fixedlyed connected with axle 1, between drive sleeve 7 and the axle 1 auxiliary axle sleeve 6 is arranged.Auxiliary axle sleeve 6 makes or is made as one with drive sleeve 7 for one.Spring 5 in the drive sleeve 7 is connected with unsteady O type circle 3 by apical ring 4.
Claims (3)
1. the rotating ring mechanism of a mechanical seal comprises fluctuate hermetical ring and is fixed on drive sleeve on the axle that it is characterized in that: between described drive sleeve and the axle auxiliary axle sleeve is arranged, fluctuate hermetical ring is sleeved on auxiliary axis and puts.
2. the rotating ring mechanism of mechanical seal according to claim 1, it is characterized in that: described auxiliary axle sleeve and drive sleeve are that one is made or be made as to one.
3. the rotating ring mechanism of mechanical seal according to claim 1 and 2 is characterized in that: be set with axle sleeve on the described axle, auxiliary axle sleeve is arranged between this drive sleeve and the axle sleeve.
