Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.Should be understood that, embodiment described herein only is used for description and interpretation the present invention, is not limited to the present invention.
In the present invention, in the situation that do opposite explanation, the noun of locality of use typically refers to left and right direction in accompanying drawing as " left and right ".
Fig. 2 has shown that coupling 4 of the present invention is arranged on the use condition in the Belt Conveyors with double-drive device.Wherein, a side of driving drum 2 (left side in Fig. 2) can be connected with speed reducer 1 by existing coupling, and the opposite side of driving drum 2 (right side in Fig. 2) can be connected with speed reducer 1 by coupling 4 of the present invention.Certainly, it is fully passable all using coupling 4 of the present invention in driving drum 2 both sides, and the present invention does not limit this.
Referring to Fig. 3, coupling of the present invention comprises coupling core body 10, drive sleeve 20 and check seat 30, the two ends of coupling core body 10 radially are formed with transmission unit 11 and Check Division 12 along coupling core body 10 respectively, drive sleeve 20 coordinates with transmission unit 11 installs for the transferring power moment of torsion, and check seat 30 coordinates with Check Division 12 to be installed for check.
Therefore, after being applied in the coupling 4 of the invention described above in the conveyor with double-drive device that Fig. 2 shows, under common runnability, conveyor uses a drive unit, and by existing coupling (or coupling of the present invention 4), moment is passed to driving drum 2 after slowing down via speed reducer 1.Simultaneously, at the opposite side (right side) of driving drum 2, coupling 4 of the present invention is installed, and this coupling 4 disconnects with the speed reducer 1 that is in closed condition.Because the coupling 4 of inventing has Check Division 12, have return-stopping function coordinate installation with check seat 30 after, thereby this moment, coupling 4 of the present invention can play the effect of check.
When the drive unit of above-mentioned connection breaks down or needs to be serviced, coupling and the speed reducer 1 of driving drum 2 one sides are disconnected, and the coupling of the present invention 4 of driving drum 2 opposite sides is connected on speed reducer, open the drive unit of opposite side, make the conveyor state of can resuming work at short notice.At this moment, coupling 4 of the present invention plays the effect of carry-over moment and check simultaneously.
Preferably, as shown in Figure 3, the outer ring of Check Division 12 greater than the outer ring of transmission unit 11, when maintenance or replacing damage parts, removes after being convenient to check seat 30 is passed from the outer ring of transmission unit 11 like this in coupling 4 of the present invention.
Be appreciated that the transmission unit 11 in coupling 4 of the present invention can have the various structures form, connect rear telescopic coupling structure, the flanged type coupling structure etc. of forming with speed reducer output shaft 5 such as having.Equally, the Check Division 12 in coupling 4 of the present invention also has the various structures form, the Check Division 12 that makes the different structure form with can form ratchet-type reverse-stop type structure of contactless wedge-shaped blocks reverse-stop type structure, contact-type etc. after check seat 30 coordinates.
In other words, the present invention does not limit the specific constructive form of transmission unit 11 and Check Division 12, everyly can realize simultaneously that the coupling of transferring power square and return-stopping function all falls into protection scope of the present invention.A kind of preferred implementation of coupling 4 of the present invention is below only described.
As shown in Fig. 5 and Fig. 6 C, be formed with first gear teeth (not indicating) on the outer ring of transmission unit 11, be formed with groove (not indicating) on the inner ring of drive sleeve 20, interval between adjacent two first gear teeth form cavity 21 relative to groove is provided with the elastic 22 for transmission in this cavity 21.This elastic 22 also has the performance of buffering, damping except can be used in driving torque, thereby has reduced the vibration of transmission system, has reduced the maximum load that produces when being subject to impacting.Wherein, elastic 22 can be nylon column, rubber column etc., the preferred nylon column that uses in the present invention.
As can clearly be seen that in Fig. 3, speed reducer output shaft 5 is arranged on together with speed reducer shaft coupling halfbody 7, speed reducer shaft coupling halfbody 7 is passed to drive sleeve 20 by another elastic 22 with the moment of rotation of speed reducer output shaft 5, then drive sleeve 20 is again by elastic 11 carry-over moments between drive sleeve 20 and transmission unit 11, thereby coupling core body 10 is rotated, realized the driven off by shaft function of connection.
As shown in Fig. 4 and Fig. 6 B, be formed with second gear teeth on the outer ring of Check Division 12, be limited with the chamber 31 of each interval between the outer ring of the inner ring of check seat 30 and Check Division 12, be provided with roller 32, elastic component 33 and roller slide block 34 for check in this chamber 31.Above-mentioned backstop structure has identical working principle with roller type brake of the prior art.Referring to Fig. 4, when Check Division 12 rotates counterclockwise, will drive roller 32 and freely rotate in check seat 30, when Check Division 12 clockwise rotates, roller 32 will be contacted with check seat 30, thereby limit the rotation of roller 32 by frictional force, realized return-stopping function.
Above-mentioned elastic 22 and roller 32 are according to different actual conditions such as carry-over moment sizes and can have different length.Therefore, after elastic 22 or roller 32 damages, for the ease of changing, preferably, make distance between transmission unit 11 and Check Division 12 greater than the length of the longer one of length in elastic 22 and roller 32.
In addition, for prevent that elastic 22 and roller 32 from coming off respectively from transmission unit 11 and Check Division 12, can be in the transmission unit 11 towards the Check Division side of 12 transmission unit back-up ring 41 is installed, this transmission unit back-up ring 41 is arranged on drive sleeve 20 by fastening piece (as bolt); And Check Division back-up ring 42 is installed in 12 both sides in the Check Division, and this Check Division back-up ring 42 is arranged on check seat 30 by fastening piece (as bolt).
Be appreciated that for convenience of installation or removal transmission unit back-up ring 41 and Check Division back-up ring 42, transmission unit back-up ring 41 and Check Division back-up ring 42 can be set to split type, transmission unit back-up ring 41 and Check Division back-up ring 42 all are semicircle shape in other words.As shown in Figure 3, the transmission unit back-up ring 41 of semicircle shape and Check Division back-up ring 42 respectively from top or the bottom carry out installation or removal.
Certainly, the inner ring of coupling core body 10 has keyway 13, and this keyway 13 is used for coupling is arranged on driving roller shaft 6.About the setting of keyway 13, for technology known in those skilled in the art, be not described in detail at this.
Below describe by reference to the accompanying drawings the preferred embodiment of the present invention in detail; but; the present invention is not limited to the detail in above-mentioned mode of execution; in technical conceive scope of the present invention; can carry out multiple simple variant to technological scheme of the present invention, these simple variant all belong to protection scope of the present invention.
Need to prove in addition, each concrete technical characteristics described in above-mentioned embodiment in reconcilable situation, can make up by any suitable mode, for fear of unnecessary repetition, the present invention is to the explanation no longer separately of various possible compound modes.As long as it is without prejudice to thought of the present invention, it should be considered as content disclosed in this invention.
