Embodiment
Be elaborated below in conjunction with the embodiment of accompanying drawing to the utility model.Should be understood that embodiment described herein only is used for explanation and explains the utility model, is not limited to the utility model.
In the utility model, not do under the situation of opposite explanation, the noun of locality of use typically refers to the left and right direction in the accompanying drawing like " left and right ".
Fig. 2 has shown that the coupling 4 of the utility model is arranged on the use condition in the Belt Conveyors with double-drive device.Wherein, a side of driving drum 2 (left side among Fig. 2) can be connected with speed reducer 1 through existing coupling, and the opposite side of driving drum 2 (right side among Fig. 2) can be connected with speed reducer 1 through the coupling 4 of the utility model.Certainly, all using the coupling 4 of the utility model in driving drum 2 both sides is passable fully, and the utility model does not limit this.
Referring to Fig. 3; The coupling of the utility model 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 cooperates installation to be used for the transferring power moment of torsion with transmission unit 11, check seat 30 cooperates installation to be used for check with Check Division 12.
Therefore; After being applied in the coupling 4 of above-mentioned the utility model in the conveyor that Fig. 2 shows with double-drive device; Under common runnability; Conveyor uses a drive unit, and via speed reducer 1 slow down the back through existing coupling (or coupling 4 of the utility model) with transmission of torque to driving drum 2.Simultaneously, at the opposite side (right side) of driving drum 2 coupling 4 of the utility model is installed, and this coupling 4 breaks off with the speed reducer that is in closed condition 1.Because the coupling 4 of model utility has Check Division 12, cooperate installation with check seat 30 after, have the check function, thereby the coupling 4 of the utility model can play the effect of check at this moment.
When the drive unit of above-mentioned connection breaks down or needs to be serviced; The coupling and the speed reducer 1 of driving drum 2 one sides are broken off; And the coupling 4 of the utility model of driving drum 2 opposite sides is connected on the speed reducer; Open the drive unit of opposite side, make the conveyor state of can resuming work at short notice.At this moment, the coupling 4 of the utility model plays the effect of carry-over moment and check simultaneously.
Preferably, as shown in Figure 3, the outer ring of Check Division 12, removes after being convenient to check seat 30 passed from the outer ring of transmission unit 11 like this in maintenance or when change damaging parts greater than the outer ring of transmission unit 11 in the coupling 4 of the utility model.
Be appreciated that the transmission unit 11 in the coupling 4 of the utility model can have multiple structural type, for example can have and connect the back with speed reducer output shaft 5 and form telescopic shaft coupling structure, flanged type shaft coupling structure etc.Equally, the Check Division 12 in the coupling 4 of the utility model also has multiple structural type, 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 cooperates.
In other words, the utility model does not limit the specific constructive form of transmission unit 11 and Check Division 12, and every coupling of transferring power square and check function of can realizing simultaneously all falls into the protection domain of the utility model.A kind of preferred implementation of the utility model coupling 4 is below only described.
Shown in Fig. 5 and Fig. 6 C; On the outer ring of transmission unit 11, be formed with first gear teeth (not indicating); On the inner ring of drive sleeve 20, be formed with groove (not indicating) at interval; Interval between adjacent two first gear teeth forms cavity 21 relatively with groove, in this cavity 21, is provided with the elastic cylinder 22 that is used for transmission.This elastic cylinder 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 receives when impacting being produced.Wherein, elastic cylinder 22 can be nylon column, rubber column etc., the preferred nylon column that uses in the utility model.
As can clearly be seen that among Fig. 3; Speed reducer output shaft 5 is installed in together with speed reducer shaft coupling halfbody 7; Speed reducer shaft coupling halfbody 7 is passed to drive sleeve 20 through another elastic cylinder 22 with the moment of rotation of speed reducer output shaft 5; Drive sleeve 20 is passed through elastic cylinder 11 carry-over moments between drive sleeve 20 and the transmission unit 11 more then, thereby coupling core body 10 is rotated, and has realized the function of shaft coupling transmission.
Shown in Fig. 4 and Fig. 6 B; On the outer ring of Check Division 12, be formed with second gear teeth; 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, in this chamber 31, be provided with the roller 32, elastic component 33 and the roller slide block 34 that are used for check.Above-mentioned check 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 in check seat 30, freely rotate, when Check Division 12 clockwise rotates, roller 32 will be contacted with check seat 30, thereby pass through the rotation of frictional force restriction roller 32, realized the check function.
Above-mentioned elastic cylinder 22 and roller 32 are according to different situation such as carry-over moment sizes and can have different length.Therefore, after elastic cylinder 22 or roller 32 damages,, preferably, make distance between transmission unit 11 and the Check Division 12 greater than the length of length in elastic cylinder 22 and the roller 32 than length for the ease of changing.
In addition, from transmission unit 11 and Check Division 12, come off respectively for preventing elastic cylinder 22 and roller 32, 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 installed on the drive sleeve 20 through fastening piece (like bolt); And in the Check Division Check Division back-up ring 42 is installed in 12 both sides, this Check Division back-up ring 42 is installed on the check seat 30 through fastening piece (like bolt).
Be appreciated that to making things convenient for installation or removal transmission unit back-up ring 41 and Check Division back-up ring 42 can transmission unit back-up ring 41 and Check Division back-up ring 42 be set to split type, transmission unit back-up ring 41 all is semicircle shape with Check Division back-up ring 42 in other words.As shown in Figure 3, the transmission unit back-up ring 41 of semicircle shape with 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 installed in driving roller shaft 6.About the setting of keyway 13,, be not described in detail at this for technology known in those skilled in the art.
More than combine accompanying drawing to describe the preferred implementation of the utility model in detail; But; The utility model is not limited to the detail in the above-mentioned mode of execution; In the technical conceive scope of the utility model, can carry out multiple simple variant to the technological scheme of the utility model, these simple variant all belong to the protection domain of the utility model.
Need to prove in addition; Each concrete technical characteristics described in above-mentioned embodiment under reconcilable situation, can make up through any suitable manner; For fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible compound modes.As long as its thought without prejudice to the utility model, it should be regarded as content disclosed in the utility model.
