Abstract

The utility model discloses a shaft coupling mechanism comprising a driving shaft (10) and a driven shaft (12). An end part of the driven shaft (12) is provided with an accommodating groove (13) accommodating the driving shaft end part (10). The shaft coupling mechanism is characterized in that at least two opening grooves (14) are arranged at intervals on the side wall of the accommodating groove (13) along the length of the accommodating groove (13); and the driven shaft (12) is provided with a locking sleeve (16) sleeved on one end of the accommodating groove (13). The shaft coupling mechanism is advantaged by safety, reliability, long service life and convenient installation, maintenance and disassembling.

Description

The coupling mechanism of axle and axle

Technical field

The utility model relates to a kind of coupling mechanism, relates in particular to the connecting structure of a kind of axle and axle.

Background technique

In mechanical transmission, often can need to carry out between axle and axle transmission of power, such as: between the main shaft of centrifugal pump or self-priming pump etc. and electric machine main shaft, need to carry out transmission of power, for realizing the transmission of above-mentioned power, first need electric machine main shaft to connect with pump main shaft, thereby make the common rotation of diaxon to transmit motion or torque, the existing online mechanism of diaxon is conventionally by driving shaft, driven shaft and linkage member form, specifically as shown in Figure 1, the end of driving shaft 3 is stretched in driven shaft 2, on driving shaft 3 and driven shaft 2, offer respectively keyway, in keyway, be provided with linking bond 1, side is locked by hexagon socket head cap screw 4 without a head, rotation when though the connecting mode of this kind of driving shaft and driven shaft can be realized diaxon, but the processing of keyway is more difficult, precision is difficult to reach requirement, particularly the keyway in driven shaft 2 is deep, add man-hour precision and more difficultly reach requirement, to such an extent as to the installation of coupling mechanism and repair demolition process, more difficult, also can cause its fluctuation of service simultaneously, have a strong impact on working life.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of installation, maintenance and dismantles the more conveniently coupling mechanism of axle and axle.

For solving the problems of the technologies described above, the utility model provides the coupling mechanism of a kind of axle and axle, comprise driving shaft and driven shaft, the end of described driven shaft has the tank of accommodating described driving shaft end, on the sidewall of described tank, along at least two opening slots that offer at its length interval, the one end on described driven shaft with described tank 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 matching with screw.

Compared with prior art, the beneficial effects of the utility model are:

Because the coupling mechanism of axle of the present utility model and axle offers at least two opening slots on the tank of accommodating driving shaft end, driven shaft end, these two opening slots have been separated into the sidewall of tank the two-part at interval, during use, first the end of driving shaft is stretched in tank, then by screw locking, make lock sleeve endoporus size reduction, thereby clamping driven shaft, existence due to opening slot, under the effect of lock sleeve clamping force, driven shaft is provided with the size reduction of tank one end, and then clamping driving shaft, the effective like this area that has increased power transmission, make diaxon in the power transmission of high speed load, safety and reliability, not fragile, thereby there is longer working life, in assembling, in maintenance process, be easier to the location of driven shaft, dismounting, thereby reduced operation easier, shortened the operation used time, therefore the utility model is safe and reliable, working life is longer, install, repair demolition is more convenient.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail

Referring to shown in Fig. 2 to Fig. 5, the coupling mechanism of a kind of axle of the present utility model and axle, comprise driving shaft 10, driven shaft 12 and lock sleeve 16, the tank 13(that wherein end of driven shaft 12 has accommodating driving shaft 10 ends is referring to Fig. 3), this tank 13 coordinates with the end shape of driving shaft 10, specialization of the present utility model is: along its length interval on the sidewall of tank 13, 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 spaced two-part, in pocket walls, be arranged with lock sleeve 16, during use, first the end of driving shaft 10 is stretched in the tank 13 of driven shaft 12, then by screw 15 lockings, make the endoporus size reduction of lock sleeve 16, thereby clamp driven shaft 12, existence due to opening slot 14, under the effect of lock sleeve 16 clamping forces, driven shaft 12 is provided with the size reduction of tank 13 one end, 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 there is longer working life, in assembling, in maintenance process, be easier to the location of driven shaft, dismounting, thereby reduced operation easier, shortened the operation used time.

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 coordinating with screw 15 that offers, during use, by tightening the screw, just can make the aperture of locking ring dwindle, thereby clamp driven shaft 12.

In sum, the utlity model has long, installation, maintenance in safe and reliable, working life and dismantle more conveniently advantage.

The foregoing is only better embodiment of the present utility model; protection domain of the present utility model is not limited with above-mentioned mode of execution; in every case the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or is changed, and all should include in the protection domain of recording in claims.
