Abstract
The utility model discloses a coupling, comprising a transmission output shaft and a work shaft, an upper hub body sleeves the end of the transmission output shaft via an expansion coupling sleeve, a lower hub body sleeves the input end of the work shaft via another expansion coupling sleeve, in this way, the upper hub body and the transmission output shaft, the lower hub body and the work shaft are respectively connected to be an integral body, the upper hub body and the lower hub body are also locked together via a bolt and a nut, the lower part of the expansion coupling sleeve in the lower hub body is provided with a bearing ring capable of realizing cooperative positioning with the work shaft. Via adjusting an adjusting bolt of the expansion coupling sleeve, the expansion coupling sleeve, under the effect of an axial force, is characterized by reduction of the inner ring and expansion of the outer ring, the upper hub body and the transmission output shaft are tightly attached to each other, the lower hub body and the work shaft are tightly attached to each other, generating enough friction, to realize transmission of torque or axial force or composite load of the torque or the axial force. Meanwhile, the bearing ring is increased at the outer section of the expansion coupling sleeve, guaranteeing safety of axial weight.
Description
Technical field
The utility model relates to a kind of coupling, particularly a kind of coupling that is applicable to vertical power transmission.
Background technique
Coupling generally is applied to the occasion of horizontal power transmission, divides rigidity and elasticity two big classes.Rigid coupling is made up of the rigidity force transmission element, is further divided into two kinds of fixed and packaged types, is used in the occasion that could compensate the displacement between the diaxon respectively.The coupling that is adopted in the conventional design mostly is flange coupling at present, gear coupling, slide block type coupling, universal-joint spindle formula coupling, spring column pin formula, quincunx elastic coupling flexible coupling, elasticity loose piece formula coupling, coupling with rubber type element, disk friction formula coupling etc., domestic coupling is standardization mostly, general earlier according to the selected suitable type of the operating conditions of machine, the rotating speed and the axle head diameter of calculating torque, axle are selected the model and the size that need from standard then.
As shown in Figure 1, the power of vertical stirrer is exported to the working shaft 25 of vertical stirrer through motor 21, high speed coupling 22, speed reducer 23, need vertical the connection between the output shaft of this speed reducer 23 and the working shaft of vertical stirrer 25, like this, the design of the coupling 24 of this Vertical direction and the conditionality of selecting not only to be subjected to torque, and to bear bigger axial force, ordinary circumstance adopts folder shell-type coupling and band pipe nipple coupling to realize transmitting torque.Go up the weight of attachment up to counting ton hour when the deadweight or the axle of vertical junction axle, transmitting torque then is not that a folder shell-type coupling can bear.
The model utility content
Technical problem to be solved in the utility model is at the prior art deficiency, to provide a kind of and can bear the coupling of larger axis to power again by transmitting torque.
For solving the problems of the technologies described above, the technological scheme that the utility model adopted is: a kind of coupling, comprise transmission output shaft and working shaft, the end of this transmission output shaft is arranged with upper hub body by the swelling connecting sleeve, the input end of this working shaft is arranged with down the hub body by another swelling connecting sleeve, so just make upper hub body and transmission output shaft, following hub body and working shaft be linked to be integral body respectively, this upper and lower hub body also locks together by bolt and nut, and the swelling connecting sleeve bottom in this time hub body is provided with the load-bearing ring that can realize cooperating the location with working shaft.
Other hazardous mediums that take up for fear of the rotation of working shaft enter coupling, and the bottom of this time hub body is provided with the end cap of band seal ring, and this end cap with the bolt locking on hub body down.
Swelling connecting sleeve top in this upper hub body is provided with the load-bearing ring too, by the effect that cooperate location and swelling connecting sleeve of load-bearing ring with transmission output shaft, upper hub body and transmission output shaft is linked into an integrated entity.
Be respectively equipped with dust cover on the relative surface of contact of this upper and lower hub body, and be locked on corresponding transmission output shaft or the working shaft by Cock screw.
This swelling connecting sleeve is a bipyramid face expansion set.
Compared with prior art, the beneficial effect that the utility model had is: the utility model adopts two swelling connecting sleeves to be positioned over respectively under coupling upper hub body and transmission output shaft and the coupling between the hub body and working shaft, adjust the adjusting bolt of swelling connecting sleeve, the inside and outside conical surface that makes the swelling connecting sleeve is under the effect of axial force, interior ring dwindles, outer shroud swells, fit tightly between upper hub body and transmission output shaft and following hub body and the working shaft, produce enough frictional force, to realize transmitting torque, axial force or both combined loads.At the swelling connecting sleeve outer section increases the load-bearing ring simultaneously, guaranteed that coupling bears the safety of axial weight under the situation that the swelling connecting sleeve may lose efficacy.

Embodiment
As Fig. 2, shown in Figure 3, the utility model one embodiment comprises transmission output shaft 1 and working shaft 7, the end of this transmission output shaft 1 is arranged with upper hub body 12 by swelling connecting sleeve 5, the input end of this working shaft 7 is arranged with down hub body 13 by another swelling connecting sleeve 5, this upper and lower hub body 12,13 is by bolt 2 and nut 4 lockings, swelling connecting sleeve 5 bottoms in this time hub body 13 also are provided with load-bearing ring 6, to bear thrust load.The bottom of this time hub body 13 is provided with the end cap 11 of a band seal ring, and this end cap 11 locks on following hub body 13 by bolt 9.Also can be provided with load-bearing ring 6 in this upper hub body 12, the top of this upper hub body 12 also can be provided with the end cap (not shown) of a band seal ring, and this end cap also locks on upper hub body 12 by bolt.Be respectively equipped with dust cover 14 on the relative surface of contact of this upper and lower hub body 12,13, and be locked on the corresponding axle by Cock screw 15.
In the present embodiment, this swelling connecting sleeve 5 is preferably bipyramid face expansion set.
Like this, adjust the adjusting bolt of swelling connecting sleeve 5, the inside and outside conical surface that makes the swelling connecting sleeve is under the effect of axial force, interior ring dwindles, outer shroud swells, fit tightly between upper hub body 12 and transmission output shaft 1 and following hub body 13 and the working shaft 7, produce enough frictional force, to realize transmitting torque, axial force or both combined loads.At swelling connecting sleeve 5 outer section increases load-bearing ring 6 simultaneously, to guarantee the safety of axial weight.
