As a kind of embodiment of the present utility model, described clamping device comprises a clip, and clip is placed in second of shaft coupling axle sleeveKeyway end end and its inner side are provided with the key-groove corresponding with the second keyway, described shaft coupling axle sleeve the second keyway end end faceRelatively extend vertically respectively an armlet to both sides, described armlet is close on clip outer wall and limits clip along shaft coupling axle sleeveEnd face move, armlet end face is provided with axial thread hole, separately has a pressure ring to be pressed on clip outer face, pressure ring is provided with and secondThe quadruple linkage groove that keyway is corresponding, pressure ring is provided with through hole in the position corresponding with armlet end face axial screwed hole, and pressure ring passes through screwThereby be fastenedly connected with armlet the second keyway end end that clip is fixed on to shaft coupling axle sleeve.
Further, described pin is provided with external screw thread.
Further, a free end of described clip is provided with through hole, another free end is provided with screwed hole, and two free ends are to pass through spiral shellTie and connect and lock.
Compared with prior art, the utility model has following beneficial effect:
The utility model uses clamping mode to carry out axial location to motor shaft can effectively ensure the coaxial of motor shaft and pump shaftDegree, thereby the situation of minimizing pump shaft off-axis; Use the mode of key transmission to there will not be skidding, motor shaft and water pump simultaneouslyAxle carrys out transmitting torque by key and keyway, and keyway leaves on shaft coupling axle sleeve simultaneously, and this all-in-one-piece structure makes this practicality newThe ability of type driving torque improves greatly.

Detailed description of the invention
Below in conjunction with accompanying drawing, with embodiment, the utility model is described in further detail.
As shown in Fig. 4 to 5, a kind of assembly type shaft coupling for pipeline circular centrifugal pump, comprises shaft coupling axle sleeve 5, its endoporusTwo ends in order to connect pump shaft 2 and motor shaft 1, are provided with in one end of shaft coupling axle sleeve 5 in the first keyway 51, the other end and establish respectivelyHave the second keyway 52, shaft coupling axle sleeve 5 connects the torque drive realizing with motor shaft 1, pump shaft 2, shaft coupling axle sleeve 5 by keyOn the jacket wall that is positioned at first key groove one end, have through hole 53; In the time that reality is used, pump shaft 2 is in the position corresponding with through hole 53Be set up and have threaded locating hole 21, and be screwed into the interior water pump of realizing of locating hole 21 with externally threaded pin 6 by through hole 53The axial location of axle 2, shaft coupling axle sleeve 5 is fixed with clamping device for motor shaft 1 is pressed from both sides in the second keyway end endThe existing axial location of consolidation; Wherein clamping device comprises a clip 7, and a free end of clip 7 is provided with through hole, another free end is establishedHave screwed hole, two free ends are connected and locked by bolt 71, and clip 7 is placed in the second keyway end end of shaft coupling axle sleeve 5Its inner side is provided with the key-groove 72 corresponding with the second keyway 52, relatively the dividing to both sides of shaft coupling axle sleeve 5 second keyway end end facesDo not extend vertically an armlet 54, armlet 54 is close on clip 7 outer walls and limits the end face of clip 7 along shaft coupling axle sleeve 5Mobile, armlet 54 end faces are provided with axial thread hole 55, separately have a pressure ring 8 to be pressed on clip 7 outer faces, pressure ring be provided withThe quadruple linkage groove 81 of the second keyway 52 correspondences, pressure ring 8 is provided with through hole in the position corresponding with armlet end face axial screwed hole 55,Thereby pressure ring 8 is fastenedly connected by screw 9 and armlet 54 the second keyway end end that clip 7 is fixed on to shaft coupling axle sleeve 5.
As shown in Figure 6, concrete using method of the present utility model: pump shaft be inserted in one end of shaft coupling axle sleeve and pacify with keyBe contained in the first keyway and realize the torque drive between pump shaft and shaft coupling, being then screwed into locating hole with pin gets final product axial restraintPump shaft; Two free ends of shaft coupling clip in releasing orientation, are inserted into another of shaft coupling axle sleeve by motor shaft before not installingIn end, and key is arranged in the second keyway and realizes the torque drive between motor shaft and shaft coupling, the bolt of tightening on clip willTwo free end lockings of clip, thus make clip hold motor shaft tightly, realize the axial restraint of motor shaft, because clip is only responsible forTransmit axial force, not transmitting torque, and also the axial force of motor shaft will be far smaller than torsional forces, the clamping that clip need to be very littlePower just can have been fixed shaft coupling and motor shaft, in the time that shaft coupling will be dismantled or will adjust axial location, only needs pine a littleThe bolt of expense nail and clip just can have been realized, and greatly facilitates assembling and maintenance.
