The purpose of this utility model is: at the deficiencies in the prior art, the utility model provides a kind of good sealing effect, can make water pump spindle rotation water pump seal device more flexibly.
To achieve these goals, the utility model has adopted following technological scheme:
A kind of water pump seal device, comprise and be set in the outer main collar of water pump spindle, the described main collar is arranged with the auxiliary sleeve ring outward, one side of the described main collar is provided with the main collar flange of radial outward, the described auxiliary collar is provided with the auxiliary collar flange that radial outward arranges away from a side of main collar flange, the side that described main collar flange is relative with auxiliary collar flange forms for outer ring cavity, be provided with elastic device in the described outer ring cavity, the both sides of described elastic device respectively with the setting that offsets of described main collar flange and described auxiliary collar flange.
As preferably, described elastic device comprises shell fragment and elastomer, the setting that offsets of one end of described shell fragment and auxiliary collar flange, shell fragment away from the setting that offsets of an end of auxiliary collar flange and elastomer, the setting that offsets of the outer side wall of a described elastomeric end and shell fragment, elastomer is away from the setting that offsets of an end of shell fragment and described main collar flange.After adopting above-mentioned preferred version, the elastic force of elastic device is better.
As preferably, the outer side wall of described shell fragment is provided with the shell fragment groove, and described shell fragment groove is circular groove, is provided with spring in the described circular groove.After adopting above-mentioned preferred version, the spring that is set to of shell fragment groove provides the mounting point, spring is set after, the butt between shell fragment and the elastomer is tightr.
As preferably, the periphery of described main collar flange forms the main latch closure limit of overlapping along towards auxiliary collar flange direction bending and extend.After adopting above-mentioned preferred version, main cover latch closure limit can be securely fixed in elastomer between main collar flange and the auxiliary collar flange, avoids elastomeric loosening dropping.
As preferably, the periphery of described auxiliary collar flange forms auxiliary sleeve latch closure limit along towards main collar flange direction bending and extend.After adopting above-mentioned preferred version, auxiliary sleeve latch closure limit can be securely fixed in shell fragment between main collar flange and the auxiliary collar flange, avoids the loosening of shell fragment to drop.
As preferably, described elastomer is provided with the elastomer boss by a side of shell fragment, the setting that offsets of the outer side wall of described elastomer boss and shell fragment.After adopting above-mentioned preferred version, the arranging of elastomer boss can be avoided the relative slippage between shell fragment and the elastomer, can play shell fragment and elastomeric position-limiting action.
As preferably, described elastomer is provided with the elastomer fixture block by a side of main collar flange.After adopting above-mentioned preferred version, elastomer can form the better fit installation with the main collar by a side of main collar flange, installs more firm.
Water pump seal device of the present utility model adopts two collars, and the main collar is set in outside the water pump spindle, the outer sheathed auxiliary sleeve ring of the main collar, the rotation of water pump spindle is more flexible, simultaneously, arranging of main collar flange and auxiliary collar flange can cooperate more closely with pump housing formation, and sealing effect is better.
Description of drawings
Fig. 1 is the utility model embodiment's mounting structure schematic representation;
Fig. 2 is the utility model embodiment's structural representation.
Embodiment
As Fig. 1-shown in Figure 2, embodiment of the present utility model specifically is a kind of water pump seal device, comprise and be set in the outer main collar 1 of water pump spindle, the main collar 1 outer auxiliary sleeve ring 2 that is arranged with, one side of the main collar 1 is provided with the main collar flange 11 of radial outward, and the auxiliary collar 2 is provided with the auxiliary collar flange 21 that radial outward arranges away from a side of main collar flange 11.Main collar flange 11 and auxiliary collar flange 21 relative sides form for outer ring cavity 3.Be provided with elastic device 4 in the outer ring cavity 3, the both sides of elastic device 4 respectively with the setting that offsets of main collar flange 11 and auxiliary collar flange 21.
Elastic device 4 comprises shell fragment 41 and elastomer 42, the setting that offsets of an end of shell fragment 41 and auxiliary collar flange 21, shell fragment 41 away from the setting that offsets of an end of auxiliary collar flange 21 and elastomer 42.The setting that offsets of one end of elastomer 42 and the outer side wall of shell fragment 41, elastomer 42 is away from the setting that offsets of an end of shell fragment 41 and main collar flange 11.The outer side wall of shell fragment 41 is provided with shell fragment groove 411, and shell fragment groove 411 is circular groove, is provided with spring 43 in the circular groove.Elastomer 42 is provided with elastomer boss 421 by a side of shell fragment 41.The setting that offsets of the outer side wall of elastomer boss 421 and shell fragment 41.Elastomer 42 is provided with elastomer fixture block 422 by a side of main collar flange 11.
