Model utility content
The purpose of this utility model provides a kind of borehole shaft drivenpump drive shaft sleeve coupling, and this coupling can avoid causing because of the reversion of transmission shaft connection between axle to get loose, and eliminates the harm that equipment safety operation is potential.
In order to realize above-mentioned technical characteristics, the purpose of this utility model is achieved in that a kind of borehole shaft drivenpump drive shaft sleeve coupling, it comprises lower drive shaft and uploads moving axis, the axle head of lower drive shaft is processed with lower circular groove, the axle head uploading moving axis is processed with circular groove, lower circular groove and upper circular groove realize axially locating by snap ring is in mating connection, lower drive shaft and upload moving axis and to match with box coupling transmitting torque respectively by lower flat key and upper flat key, one end of box coupling has been bolted to connection thrust snap ring, thrust snap ring carries out thrust location by the circular groove uploaded on moving axis.
The inwall of described box coupling is processed with the keyway matched with lower flat key and upper flat key.
Described lower drive shaft is processed with the axle head uploading moving axis the keyway matched with lower flat key and upper flat key.
Described snap ring is split type structure.
Described thrust snap ring is split type structure.
The utility model has following beneficial effect:
In use, lower drive shaft and upload moving axis and carry out axial connection by snap ring, form flat key by lower flat key and upper flat key between two transmission shafts and box coupling and be in transmission connection, transmitting torque, box coupling is then positioned on axle by thrust snap ring.Adopt said structure can avoid causing because of the reversion of transmission shaft connection between axle to get loose, cause potential harm to the safe operation of equipment.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.

In figure: lower drive shaft 1, lower flat key 2, box coupling 3, lower circular groove 4, snap ring 5, upper circular groove 6, upper flat key 7, thrust snap ring 8, bolt 9, circular groove 10, upload moving axis 11, screwed coupling 12.
Embodiment
Below in conjunction with accompanying drawing, mode of execution of the present utility model is described further.
As shown in Figure 1-2, a kind of borehole shaft drivenpump drive shaft sleeve coupling, it comprises lower drive shaft 1 and uploads moving axis 11, the axle head of lower drive shaft 1 is processed with lower circular groove 4, the axle head uploading moving axis 11 is processed with circular groove 6, lower circular groove 4 and upper circular groove 6 realize axially locating by snap ring 5 is in mating connection, lower drive shaft 1 and upload moving axis 11 and to match with box coupling 3 transmitting torque respectively by lower flat key 2 and upper flat key 7, one end of box coupling 3 is fixedly connected with thrust snap ring 8 by bolt 9, thrust snap ring 8 carries out thrust location by the circular groove 10 uploaded on moving axis 11.Lower drive shaft 1 can either be realized by above-mentioned structure and upload axially locating between moving axis 11 connecting, the moment of torsion transmission that can also realize between two axles by the cooperation of box coupling 3.
Further, the inwall of described box coupling 3 is processed with the keyway matched with lower flat key 2 and upper flat key 7.The transmission realizing moment of torsion is connected by key.
Further, described lower drive shaft 1 is processed with the axle head uploading moving axis 11 keyway matched with lower flat key 2 and upper flat key 7.The transmission realizing moment of torsion is connected by key.
Further, described snap ring 5 is split type structure.Adopt split type structure can facilitate the installation of snap ring 5.
Further, described thrust snap ring 8 is split type structure.Adopt split type structure conveniently to install, the axially locating of box coupling 3 can be realized by thrust snap ring 8.
See Fig. 3, be the assembly structure schematic diagram of the original screwed coupling 12 of the utility model, adopt this kind of coupling easily to make thread looseness when transmission shaft rotates backward thus cause loosening of diaxon.
Concrete installation process of the present utility model is:
First lower drive shaft 1 and the diaxon end of uploading moving axis 11 are aligned during installation, again two pieces of points of half snap rings 5 are blocked, insert lower flat key 2 and upper flat key 7, the sleeve of box coupling 3 is in place from top to bottom, be finally two thrust snap rings 8 are stuck in the circular groove 10 that formed between box coupling 3 and transmission shaft, screw the fixing bolt 9 of two thrust snap rings 8.
Working principle of the present utility model is:
The drive shaft sleeve coupling of borehole shaft drivenpump realizes the transmission between transmission shaft by the flat key be fixed between two transmission shafts and box coupling keyway, connection between two transmission shafts is realized by the split type snap ring be stuck in the circular groove of axle two ends, and the axially locating of box coupling is two semicircle thrust snap rings by being stuck in circular groove between transmission shaft and sleeve has come, two semicircle thrust snap rings are then fixed by two bolts be fixed on above box coupling.
Advantage of the present utility model:
Traditional screwed coupling can cause motor reversal and then transmission shaft is reversed because of the aqueous reflux in pipeline when deep-well pump motor stops, transmission shaft reversion can cause between screwed coupling and transmission shaft and get loose, and brings potential harm to deep-well pump safe and stable operation.And the transmission between box coupling transmission shaft realizes by flat key and sleeve, get loose even motor reversal also can not be connection between transmission shaft.Its two be adopt flat key transmission to be compared to its load carried of screw-driven can be larger, be especially applicable to powerful borehole shaft drivenpump.
Above-described embodiment is used for explaining and the utility model is described; instead of the utility model is limited; in the protection domain of spirit of the present utility model and claim, any amendment make the utility model and change, all fall into protection domain of the present utility model.
