Abstract
The utility model provides a shaft joint technic proposal used in fluid, essentially consisting of a coupling rod, coupling sleeves, and a bearing arranged between the coupling rod and the coupling sleeves. According to the proposal, a boss is arranged in the middle part of the coupling rod, and two bearings respectively sleeve the coupling rods at both sides of the coupling rod boss. Both outer ends of the bearing is sleeved by coupling sleeves, the middle part of the coupling sleeves is provided with an inner coupling-sleeve boss corresponding to the coupling rod boss. An end flange is respectively fixed to the end sealing ring of the coupling sleeve through a fixing screw bolt, an outer end sealing ring and an inner end sealing ring, and a mechanic sealing organ are respectively arranged between each bearing and the corresponding end flange. A shaft collar is fixed to the coupling rod of the mechanic sealing organ through the bearing, and drives a transition ring to rotate together with the coupling rod through a spring. The transition ring connects a rotary ring that can rotate together with the coupling rod through the sealing ring of the rotary ring, and the rotary ring squeezes the stationary ring, and a stationary ring sealing ring is arranged between the end flange and the stationary ring.
Description
Affiliated technical field:
The utility model relates to a kind of coupling that two rotating shafts connect, especially a kind of coupling that is used for liquid of being used for.
Background technique:
In the prior art, the known coupling that is used for the rotating shaft connection is that bearing is housed on coupling rod, at bearing outside load axle sleeve, the coupling of this structure can connect two rotatingshafts effectively, played connection, the effect of support and transferring power, but the coupling of this structure generally can not be used for the connection between the liquid diaxon, its reason is because sealing is relatively poor, liquid around bearing in the coupling will pollute, if surrounding liquid need keep purity, this coupling just can't adapt to, and does not still have a kind of liquid that is used for so far, and will keep the coupling of purity liquid.
Summary of the invention:
The utility model is at the existing in prior technology deficiency, and a kind of coupling technological scheme that is used for liquid is provided, and the coupling of this scheme can be used in the liquid, and liquid that can not is on every side polluted, and influences the purity of surrounding liquid.
This programme is realized by following technical measures: mainly include coupling rod, connecting shaft cover and be installed in the bearing of coupling rod between overlapping with connecting shaft, the characteristics of this programme are that a coupling rod boss is arranged at the middle part of described coupling rod, described bearing is two, be set on the coupling rod of coupling rod boss both sides, be set with described connecting shaft cover in the outer end of two bearings, there is the connecting shaft cover inner convex platform corresponding with the coupling rod boss at the middle part of this connecting shaft cover, respectively there is end flange to overlap end seal with connecting shaft at connecting shaft cover two ends and fixes, and between each bearing and relative end flange, a mechanical sealing mechanism is arranged respectively by fixing bolt and outer end seal ring.The concrete technical characterstic of this programme also has, described mechanical sealing mechanism is near bearing fixing the dead axle ring to be arranged on coupling rod, the dead axle ring by spring promote can with the co-rotational excessive ring of coupling rod, excessively ring by seal ring of moving ring connect can with the co-rotational rotating ring of coupling rod, rotating ring extruding and the fixing stationary ring of end flange.Between described end flange and stationary ring, also has the stationary ring seal ring.Between described end flange and connecting shaft cover, also has inner seal ring.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because in this scheme is that a coupling rod boss is arranged at the middle part of coupling rod, bearing adopts two, be set on the coupling rod of coupling rod boss both sides, be set with the connecting shaft cover in the outer end of two bearings, there is the connecting shaft cover boss corresponding with the coupling rod boss at the middle part of this connecting shaft cover, respectively there is end flange to overlap end seal with connecting shaft at connecting shaft cover two ends and fixes, and between each bearing and relative end flange, a mechanical sealing mechanism is arranged respectively by fixing bolt and outer end seal ring.This structure, because connecting shaft overlaps the Packed end flange in two tops, this just overlaps connecting shaft between inner chamber and the coupling rod and is sealed with the external world, be added in again mechanical sealing mechanism and stationary ring seal ring are arranged between coupling rod upper bearing (metal) and the end flange, this just will seal between coupling rod and the end flange, has formed outer coupling rod of the connecting shaft cover inner chamber and the external world and external part flange and the tight seal between the coupling rod in the end flange.The coupling of this structure, in liquid, connect two transmission shafts, can play the effect of connection, support and transferring power to two transmission shafts, and coupling is inner to be sealed again with surrounding liquid, so the bearing in the coupling just can not pollute surrounding liquid, can keep the purity of surrounding liquid.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.
