Accompanying drawing explanation
Fig. 1 is one of structural drawing of plastic-wire drawing machine clutch speed changer embodiment of the present invention.
Fig. 2 is the structural drawing two of plastic-wire drawing machine clutch speed changer embodiment of the present invention.
Below in conjunction with accompanying drawing, the present invention is described in further details.
Embodiment
As Fig. 1, shown in Fig. 2, for plastic-wire drawing machine clutch speed changer embodiment of the present invention, comprise seal case 1 that lubricant oil is housed and the reducing gear 2 with associated electric motor system, reducing gear 2 is the belt pulley be connected with motor in the present embodiment, there is in casing 1 coiling rotating shaft 3, clutch left 4, clutch right 5 and clutch operation mechanism, clutch left 4 uses No. 45 Steel materials through Quenching Treatment, right of clutch uses tin bronze to make, coiling rotating shaft 3 has the abutting end 31 be positioned at outside casing 1 and the fixed end 32 be positioned within casing, coiling rotating shaft abutting end 31 is for installing wire spool, coiling rotating shaft fixed end 32 is fixedly connected with clutch left 4, clutch right 5 is stretched out casing 1 and is fixedly connected with reducing gear 2, clutch left 4 and clutch right 5 clutches coordinate and floodlubrication oil, be positioned at its following part to be immersed among lubricant oil in accompanying drawing 1, be always kinetic friction when clutch left 4 and clutch right 5 laminating to coordinate, the kinetic force of friction that clutch operation mechanism can drive the clutch action between clutch left 4 and clutch right 5 and adjust between clutch left 4 and clutch right 5.It is larger that clutch left 4 is more adjacent to clutch right 5 kinetic force of friction between the two, otherwise less.
Aforesaid clutch right 5 has buckling groove 51, this buckling groove 51 comprises the inclined-plane 51b being positioned at middle sagittal plane 51a and being positioned at edge, clutch left 4 has the clamping block 41 coordinated with buckling groove 51, this clamping block 41 comprises the inclined-plane 41b being positioned at middle sagittal plane 41a and being positioned at edge, buckling groove inclined-plane 51b and the 41b clutch of clamping block inclined-plane coordinate and floodlubrication oil, laminating position between clutch left 4 and clutch right 5 is circular, buckling groove inclined-plane 51b and clamping block inclined-plane 41b is always kinetic friction and coordinates when fitting, kinetic force of friction between clutch operation mechanism adjustable clamp access slot inclined-plane 51b and clamping block inclined-plane 41b.
Aforesaid clutch operation mechanism comprises spring assembly 7 and operation equipment 6, spring assembly 7 comprises the tightening nut 71 axially set gradually, spring seat 72 and spring 73, spring seat 72 and spring 73 are all socketed on the fixed end 32 of coiling rotating shaft, spring 73 two ends are connected to spring seat 72 and clutch left 4 respectively, tightening nut 71 is fixedly connected with by screw thread with the fixed end 32 of coiling rotating shaft, tightening nut 71 is used for spring seat 72 and spring 73 to be axially pressed in clutch left 4, and be also the axial pressure being adjusted spring seat 72 clutch relative to spring 73 left 4 by degree of tightness tightening nut 71, and then reach the object of kinetic force of friction between the clamping block inclined-plane 41b of adjustment clutch left 4 and the buckling groove inclined-plane 51b of clutch right 5, the present embodiment is provided with two tightening nuts 71 especially in order to strengthen fixing spring seat 72 and spring 73, play dual fail-safe pressuring action.Operation equipment 6 comprise stir groove 61, stir rotating shaft 62, slide block 63 and stir handle 64, stirring groove 61 is positioned in clutch left 4, and stir groove 61 for being arranged at the radial direction fluting of clutch left 4, slide block 63 can axially movably be arranged on to be stirred among groove 61, slide block 63 bias is arranged on stirs rotating shaft 62 one end, stirs rotating shaft 62 the other end and stirs handle 64 and be fixedly connected with.When needing maintenance or change parts, only need operate and stir handle 64, can drive and stir rotating shaft 62 and rotate, stirring rotating shaft 62 drives slide block 63 to move axially until abut to the left wall of clutch left 4 stirring in groove 61 left, continue to drive clutch left 4 until be separated with clutch right 5 left, after Awaiting Overhaul has been changed, clutch left 4 resets and drives slide block 63 to move axially together, drive to stir rotating shaft 62 and stir handle 64 simultaneously and reset, until buckling groove inclined-plane 51b and clamping block inclined-plane 41b fits again, now usually can continue operation and stir handle 64, slide block 63 is continued move axially a little distance to the right stirring in groove 61, form the vacant state that slide block 63 stirs groove 61 relatively, then the laminating degree between buckling groove inclined-plane 51b and clamping block inclined-plane 41b is regulated by tightening nut 71, such ability accurately controls the kinetic force of friction between clutch left 4 and clutch right 5 well, clutch is made to enter armed state.
Owing to needing the wire vent speed coordinating extruding end constant, the receipts silk speed of the present embodiment is synchronous perfect cooperation with the silk cylinder radius of wire spool all the time: along with electric machine rotation time initial, belt pulley is driven to rotate together with clutch right 5, clutch right 5 drives clutch left 4 to rotate together with coiling rotating shaft 3 by kinetic friction, because the wire spool on now coiling rotating shaft abutting end 31 is empty, its cylinder does not produce thickness, the wire spool resistance put in coiling rotating shaft 3 is less, relative friction speed between now clutch left 4 and clutch right 5 is less, namely between clutch left 4 and clutch right 5, skid level is less, the rotating speed exporting to coiling rotating shaft 3 is very fast, the receipts silk speed of wire spool just in time with the silk cylinder radius synchronous matching of wire spool, along with the plastic wire on wire spool curls gradually, silk cylinder radius increases gradually, the wire spool resistance put in coiling rotating shaft 3 also becomes large gradually, under the prerequisite that kinetic force of friction between clutch left 4 and clutch right 5 is constant, relative friction speed between the two becomes large gradually, namely skid between clutch left 4 and clutch right 5 and aggravate, so the rotating speed exporting to coiling rotating shaft 3 becomes slow gradually, wire spool now receive silk speed also just in time with the silk cylinder radius synchronous matching of now wire spool, so the coiling performance of the present embodiment is given prominence to, make shaping after silk cylinder profile be well-balanced cylindrical, and level is clearly demarcated, marshalling, therefore to get silk very convenient laborsaving for follow-up use silk cylinder.
The present embodiment also has following improvement especially: between slide block 63 and clutch left 4, be provided with the radial bearing a arranged, clutch left 4 is erected on slide block 63 by bearing a, such slide block 63 can withstand clutch left 4 from radial direction, makes clutch left 4 smooth runnings.And in order to make coiling rotating shaft 3 smooth running, make clutch configuration compact simultaneously, reduction takes up room, the clutch right 5 of embodiment has through hole 59, coiling rotating shaft fixed end 32 is arranged among the through hole 59 of clutch right 5, is provided with clutch shaft bearing b and the second bearing c between coiling rotating shaft fixed end 32 and clutch right 5.Buckling groove inclined-plane 51b in the present embodiment and clamping block inclined-plane 41b is relatively radial in the angle between 30 degree to 60 degree, particularly preferably 51b radial direction relative to clamping block inclined-plane 41b in buckling groove inclined-plane is the angle of 45 degree, and kinetic friction performance so between the two can reach the optimum state.
Be described in detail specific embodiments of the invention above, but it is just as example, the present invention is not restricted to specific embodiment described above.To those skilled in the art, any equivalent modifications that the present invention is carried out and substituting also all among category of the present invention.Therefore, equalization conversion done without departing from the spirit and scope of the invention and amendment, all should contain within the scope of the invention.
