Abstract
The invention discloses a coupling mechanism of shafts. The coupling mechanism comprises the driving shaft (10) and the driven shaft (12), wherein the end portion of the driven shaft (12) is provided with a containing groove (13) for containing the end portion of the driving shaft (10). The coupling mechanism is characterized in that the side wall of the containing groove (13) is provided with at least two open grooves (14) at intervals in the length direction of the containing groove (13), and a locking sleeve (16) is sleeved at one end, provided with the containing groove (13), of the driven shaft (12). The coupling mechanism has the advantages of being safe, reliable, long in service life, and convenient to install, maintain and dismount.
Description
Technical field
The present invention relates to a kind of coupling mechanism, relate in particular to a kind of axle with spool connecting structure.
Background technique
Need to carry out transmission of power between axle and the axle through regular meeting in the mechanical transmission; for example: need to carry out transmission of power between the main shaft of centrifugal pump or self-priming pump etc. and the electric machine main shaft; for realizing the transmission of above-mentioned power; at first need electric machine main shaft is connected with the pump main shaft; thereby make the common rotation of diaxon to transmit motion or torque; the existing online mechanism of diaxon is usually by driving shaft; driven shaft and linkage member are formed; specifically as shown in Figure 1; the end of driving shaft 3 is stretched in the driven shaft 2; offer keyway respectively on driving shaft 3 and the driven shaft 2; be provided with linking bond 1 in the keyway, the side is locked by hexagon socket head cap screw 4 without a head, though the connecting mode of this kind driving shaft and driven shaft can be realized diaxon time rotation; but the processing of keyway is difficulty relatively; precision is difficult to reach requirement, and particularly the keyway in the driven shaft 2 is deep, adds the man-hour precision and more difficultly reaches requirement; to such an extent as to the installation of coupling mechanism and repair demolition process; relatively difficulty also can cause its fluctuation of service simultaneously, has a strong impact on working life.
Summary of the invention
Technical problem to be solved by this invention provides a kind of installation, maintenance and dismantles more convenient axle and the coupling mechanism of axle.
For solving the problems of the technologies described above, the invention provides a kind of axle with spool coupling mechanism, comprise driving shaft and driven shaft, the end of described driven shaft has the tank of ccontaining described driving shaft end, its length of the sidewall upper edge of described tank at interval offer at least two opening slots, an end that has described tank on the described driven shaft is arranged with lock sleeve.
Described two opening slots are oppositely arranged.
Described lock sleeve is the locking ring with two ends, and two ends of described locking ring are relative offers the tapped hole that matches with screw.
Compared with prior art, beneficial effect of the present invention is:
Because axle of the present invention offers at least two opening slots with the tank of coupling mechanism in ccontaining driving shaft end, driven shaft end of axle, these two opening slots have been separated into two-part at interval with the sidewall of tank, during use, at first the end of driving shaft is stretched in the tank, make by screw locking then that hole dimension reduces in the lock sleeve, thereby clamping driven shaft, because the existence of opening slot, the size that driven shaft is provided with tank one end under the effect of lock sleeve clamping force reduces, and then clamping driving shaft, the effective like this area that has increased the power transmission, make diaxon in the power transmission of high speed load, safety and reliability, not fragile, thus had long working life, in assembling, be easier to the location of driven shaft in the maintenance process, dismounting, thereby reduced operation easier, shortened the operation time spent, so the present invention has been safe and reliable, working life is longer, install, repair demolition is more convenient.

Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail
Extremely shown in Figure 5 referring to Fig. 2, a kind of axle of the present invention with spool coupling mechanism, comprise driving shaft 10, driven shaft 12 and lock sleeve 16, wherein the end of driven shaft 12 has the tank 13(of ccontaining driving shaft 10 ends referring to Fig. 3), this tank 13 cooperates with the end shape of driving shaft 10, specialization of the present invention is: its length of the sidewall upper edge of tank 13 at interval offer two opening slot 14(referring to Fig. 3), these two opening slots 14 are oppositely arranged, and the sidewall of tank is separated into the two-part that arrange at interval, be arranged with lock sleeve 16 in pocket walls, during use, at first the end of driving shaft 10 is stretched in the tank 13 of driven shaft 12, by screw 15 lockings the interior hole dimension of lock sleeve 16 is reduced then, thereby clamp driven shaft 12, because the existence of opening slot 14, the size that driven shaft 12 is provided with tank 13 1 ends under the effect of lock sleeve 16 clamping forces reduces, the aperture that is tank 13 reduces, and then the end of clamping driving shaft 10, because surface and tank 13 walls of driving shaft 10 ends are combined closely, thereby effectively increased the area that power is transmitted, make diaxon in the power transmission of high speed load, safety and reliability, not fragile, thereby had long working life, in assembling, be easier to the location of driven shaft in the maintenance process, dismounting, thus operation easier reduced, shortened the operation time spent.
Referring to shown in Figure 4, lock sleeve 16 is one to have the locking ring of two ends, and in the end of locking ring the relative tapped hole 17 that cooperates with screw 15 that offers, during use, by tightening the screw the aperture of locking ring is dwindled, thereby clamp driven shaft 12.
In sum, the present invention has advantage safe and reliable, that grow working life, the installation, maintenance dismounting is more convenient.
The above only is preferred embodiments of the present invention; protection scope of the present invention is not limited with above-mentioned mode of execution; as long as the equivalence that those of ordinary skills do according to disclosed content is modified or changed, all should include in the protection domain of putting down in writing in claims.
