Description

Rigid coupling device

Technical Field

The utility model belongs to the mechanical equipment field, specifically speaking relate to a rigidity spiale device.

Background

Present pump is in order to satisfy the operating mode, and the requirement axial length reaches four meters more than, and some footpaths are all for the path even, and the installation maintenance is dismantled inconveniently, places the axle for a long time and can take place radial bending deformation. The existing VS6 pump mainly adopts a slender shaft, and in the turning process, due to the poor rigidity of the slender shaft, the slender shaft is easy to bend and deform under the action of cutting force and cutting heat, so that the accuracy of relative movement of a cutter and a part is damaged, the machined slender shaft is in a shape with a thick middle part and two thin ends, the machining precision of the part is seriously influenced, and meanwhile, after the slender shaft bends and deforms, the vibration of a process system can be caused, the roughness of the part is influenced, and further the efficiency of the VS6 pump device is adversely influenced.

SUMMERY OF THE UTILITY MODEL

The utility model provides a solve above-mentioned problem and provide a rigidity spiale device, solved major axis installation maintenance among the background art and dismantled shortcoming such as inconvenient, the flexible deformation of being easy.

The technical scheme of the utility model is realized like this: a rigid coupling device comprises a coupling sleeve and a positioning ring, wherein the coupling sleeve and the positioning ring are of a half-and-half structure, the coupling sleeve and the positioning ring are arranged at the middle position where a driving shaft and a pump shaft are connected, the positioning ring is positioned in the coupling sleeve, a positioning groove A and a key groove which are matched with the positioning ring are arranged in the coupling sleeve, two halves of the coupling sleeve are respectively provided with a set screw hole, the two halves of the coupling sleeve are fixedly connected together through a cylindrical head screw in the set screw hole, the driving shaft and the pump shaft are respectively provided with a positioning groove B and a flat key which are matched with the coupling sleeve, and the driving shaft and the pump shaft are matched with the coupling sleeve through the flat key and the key groove;

preferably, the connecting sleeve is provided with a groove;

preferably, a spring washer is arranged on the cylindrical head screw.

The utility model has the advantages that: the utility model discloses owing to be equipped with the holding ring, the axle is equipped with the constant head tank of installation holding ring with the nipple, the axle is equipped with the keyway with the nipple, can prevent to rotate, and can guarantee sufficient moment of torsion, avoid leading to bending deformation in the course of working because of the slender axles rigidity is poor through the rigidity spiale device, and then destroy cutter and part relative motion's accuracy, thick in the middle of the axle that makes processing come out produces, the thin shape in two, seriously influence the machining precision of part, also can not be because of producing bending deformation, arouse the vibration of process system, influence the roughness of part, and then produce adverse effect to VS6 pump unit efficiency. Avoid long-time idle production to warp, guarantee that installation maintenance dismantles conveniently.
