Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
In the present invention, when not doing contrary explanation, the noun of locality of use typically refers to the left and right direction in accompanying drawing as " left and right ".
Fig. 2 shows coupling 4 of the present invention and is arranged on the service condition had in the Belt Conveyors of double-drive device.Wherein, the side (left side in Fig. 2) of driving drum 2 can be connected with speed reducer 1 by existing coupling, and the opposite side (right side in Fig. 2) of driving drum 2 can be connected with speed reducer 1 by coupling 4 of the present invention.Certainly, all use coupling 4 of the present invention to be completely passable in driving drum 2 both sides, the present invention does not limit this.
See 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 have been formed radially transmission unit 11 and Check Division 12 respectively along coupling core body 10, drive sleeve 20 coordinates with transmission unit 11 installs for transferring power moment of torsion, and check seat 30 coordinates with Check Division 12 to be installed for check.
Therefore, the coupling 4 of the invention described above is applied in having after in the conveyor of double-drive device of Fig. 2 display, 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.Meanwhile, 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 being in closed condition.Due to invention coupling 4 there is Check Division 12, coordinate with check seat 30 install after there is return-stopping function, thus, now 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, the coupling of driving drum 2 side and speed reducer 1 are disconnected, and the coupling of the present invention 4 of driving drum 2 opposite side is connected on speed reducer, open the drive unit of opposite side, conveyor can be resumed work state at short notice.Now, coupling 4 of the present invention plays the effect of carry-over moment and check simultaneously.
Preferably, as shown in Figure 3, in coupling 4 of the present invention, the outer ring of Check Division 12 is greater than the outer ring of transmission unit 11, like this overhaul or change damage parts time, remove after being convenient to check seat 30 to pass from the outer ring of transmission unit 11.
Be appreciated that the transmission unit 11 in coupling 4 of the present invention can have various structures form, such as, can have and connect the telescopic coupling structure of rear formation, flanged type coupling structure etc. with speed reducer output shaft 5.Equally, the Check Division 12 in coupling 4 of the present invention also has various structures form, can form contactless wedge-shaped blocks reverse-stop type structure, the ratchet-type reverse-stop type structure etc. of contact-type after the Check Division 12 of different structure form is coordinated with check seat 30.
In other words, the present invention does not limit the specific constructive form of transmission unit 11 and Check Division 12, and every coupling that simultaneously can realize 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, the outer ring of transmission unit 11 is formed first gear teeth (sign), the inner ring of drive sleeve 20 is formed groove (sign), interval between adjacent two first gear teeth is relative with groove forms cavity 21, is provided with the elastic 22 for transmission in this cavity 21.This elastic 22, except can be used in driving torque, also has the performance of buffering, damping, thus decreases the vibration of transmission system, reduces the maximum load produced when being subject to impacting.Wherein, elastic 22 can be nylon column, rubber column etc., preferably uses nylon column in the present invention.
As can clearly be seen that in Fig. 3, together with speed reducer output shaft 5 is arranged on speed reducer shaft coupling halfbody 7, the moment of rotation of speed reducer output shaft 5 is passed to drive sleeve 20 by another elastic 22 by speed reducer shaft coupling halfbody 7, then drive sleeve 20 is again by elastic 11 carry-over moment between drive sleeve 20 and transmission unit 11, thus coupling core body 10 is rotated, achieve the driven off by shaft function of connection.
As shown in Fig. 4 and Fig. 6 B, the outer ring of Check Division 12 is formed second gear teeth, be limited with the chamber 31 be spaced between the inner ring of check seat 30 and the outer ring of Check Division 12, be provided with in this chamber 31 for the roller 32 of check, elastic component 33 and roller slide block 34.Above-mentioned backstop structure has identical working principle with roller type brake of the prior art.See Fig. 4, when Check Division 12 rotates counterclockwise, roller 32 will be driven freely to rotate in check seat 30, when Check Division 12 rotates clockwise, roller 32 will be made to contact with check seat 30, thus limit the rotation of roller 32 by frictional force, achieve return-stopping function.
Above-mentioned elastic 22 and roller 32 can have different length according to different actual conditions such as carry-over moment sizes.Therefore, after elastic 22 or roller 32 damage, for the ease of changing, preferably, the distance between transmission unit 11 and Check Division 12 is made to be greater than the length of the longer one of length in elastic 22 and roller 32.
In addition, come off from transmission unit 11 and Check Division 12 respectively for preventing elastic 22 and roller 32, can in transmission unit 11 towards installation transmission unit, the side back-up ring 41 of Check Division 12, this transmission unit back-up ring 41 is arranged in drive sleeve 20 by fastening piece (as bolt); And installation Check Division, the both sides back-up ring 42 in Check Division 12, this Check Division back-up ring 42 is arranged on check seat 30 by fastening piece (as bolt).
Be appreciated that 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 are all in semicircle shape in other words for convenience of installation or removal transmission unit back-up ring 41 and Check Division back-up ring 42.As shown in Figure 3, the transmission unit back-up ring 41 of semicircle shape and Check Division back-up ring 42 install or remove from top or bottom respectively.
Certainly, the inner ring of coupling core body 10 has keyway 13, and this keyway 13 is for being arranged on driving roller shaft 6 by coupling.About the setting of keyway 13, be technology known in those skilled in the art, be not described in detail at this.
Below the preferred embodiment of the present invention is described in detail by reference to the accompanying drawings; but; the present invention is not limited to the detail in above-mentioned mode of execution; within the scope of technical conceive 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.
It should be noted that in addition, each concrete technical characteristics described in above-mentioned embodiment, in reconcilable situation, can be combined by any suitable mode, in order to avoid unnecessary repetition, the present invention illustrates no longer separately to various possible compound mode.As long as it is without prejudice to thought of the present invention, it should be considered as content disclosed in this invention.
