Description
Technical field
The invention belongs to technical field of textile machine, and in particular to a kind of dobbies cam gear.
Background technology
Dobbies is that woven designs tissue signal is converted into mouth-opening action and shedding above and below the heald frame of loom is driven with this
One of loom opening features of motion, dobbies is divided into two kinds of passive type and positive type by the difference of its opening form.
Foregoing negative dobby, the motion mode of its critical piece such as broaching tool, push broach and drag hook shows as reciprocal fortune
It is dynamic and comprehensive with form of springs time.It is passive however as the continuous improvement of the extensive use of shuttleless loom, especially loom speed
Because there is motional inertia impact in formula dobbies, thus not only kinetic energy consumption is big, and be difficult to ensure weaving machine high-speed smooth motion, example
As reciprocating inertia impact can cause loom high vibration；So-called positive dobby, its critical piece is as the aforementioned
The motion mode of broaching tool, push broach and drag hook shows as rotary motion and comprehensive using connecting rod time, and negative dobby can be made up completely
The foregoing disadvantage of preceding machine, is quite approved and favored by industry.
The technical information of foregoing positive dobby category can be seen in disclosed Chinese patent literature, typically such as
" loom of rotary dobby and the such dobby of equipment " that CN1057352C recommends, the patent is to FR-A-
The improvement of 2540524 patents, gains ground to reduction energy consumption and noise.But the patent does not provide the specific of cam gear
Structure.
" the crank-rocker style electronic jacquard machine " that publication No. CN106400249A is provided although disclose to a certain extent
The concrete structure of cam gear, but be due to that the patent application scheme is to be directed to the transformation of crank-rocker style electronic jacquard machine
And propose（See the 0002nd to 0004 section of specification）, thus drive cam gear structural system cam swing arm before,
The structure of the power input mechanism of rear support disk motion is complex（For details, reference can be made to the specification the 0039th of the patent application to
0040 section）If the previous power input mechanism of the patent application publication is diverted into dobbies cam gear, then extremely
The drawbacks of following two aspects being produced less：First, due to aforementioned cam swing arm front support disk can not will be driven（With changing for direction
Change can be described as " the left supporting disk of cam swing arm ", as follows）And cam swing arm rear support disk（It can be described as with the change in direction
" cam swing arm rear support disk ", it is as follows）The power input shaft gear being synchronized with the movement（Also it can claim " driving gear "）And by moving
The supporting disk drive gear that power input shaft gear drives（Also it can claim " driven gear "）The same of shield is covered by casing in receiving to casing
When lubricating oil in casing it is in good lubricating status all the time because the non-finite number of time done through the applicant
Test shows, is only changed to foregoing power input shaft gear and supporting disk drive gear by the external of prior art interior
Put formula to be transferred in casing, the stability of transmission could be ensured, reduce noise and vibration and be able to significantly extend gear
Service life and meet high-speed motion requirement；Second, due to for example needing more than transmission link to input through lower tooth roller box power successively
Axle drive lower tooth roller box, by lower tooth roller box lower tooth roller box power output shaft by shaft coupling under universal drive shaft drive universal drive shaft, by
Universal drive shaft drives upper gear box by shaft coupling on universal drive shaft, passes through gear by the upper gear box power output shaft of upper gear box
Case power output shaft shaft coupling drives transition axis, propped up by being driven with the transition axis that cam swing arm front support disk is fixed before cam swing arm
Tray, by cam swing arm front support disk drive a pair simultaneously and conjugate cam（Also it can claim " shedding cam ", it is as follows）Wheel rim
（Conjugate cam curved surface）Constitute rolling pair and the unidirectional seat of swing arm with being fixed on main shaft constitutes the swing arm motion of sliding pair, most
Make main shaft eventually by weaving process requirement campaign, thus it is not only complicated, and be unfavorable for saving energy consumption.Therefore how to use for reference
Simultaneously the rational dobbies cam gear of design structure has product to the drawbacks of being made up on the basis of prior art in prior art
Pole meaning, technical scheme described below is produced under this background.

Refer to Fig. 2 and combine Fig. 1, the action process of the applicant summary present invention：When by power input driving device
When drive input shaft 2 is moved, supporting disk drive gear is driven by the power input shaft gear 21 of the front end of power input shaft 2
41, because the left supporting disk 4 of supporting disk drive gear 41 and cam swing arm is fixed, thus by supporting disk drive gear 41 with moving cam
The left supporting disk 4 of swing arm, and because the left supporting disk 4 of cam swing arm passes through the left supporting disk fixing screws 45 of cam swing arm and cam swing arm
Fixed column screw 5411 in the fixed-wing screw fixed column 541 of the supporting disk fixed-wing 54 of left supporting disk 5 is fixed, i.e., due to convex
The wheel left and right supporting disk 4,5 of swing arm is fixed to one another, and due to the right supporting of cam swing arm of shedding cam 6 and shedding cam fixed seat 8
Cam screw fixing hole 821 on the left surface of dish axle bearing 82 is fixed（Shedding cam 6 is not rotated）, due also to cam is put
The swing arm guide holder that the swing arm guide holder 71 of the structural system of arm mechanism 7 locks clamping ring 72 and main shaft 3 by swing arm guide holder is consolidated
Determine section 31 to fix, and then because the front swing arm 73 being slidably matched with swing arm guide holder 71 is existed respectively by front swing arm support shaft 732
Corresponding to left supporting disk clutch shaft bearing 431 and right supporting disk clutch shaft bearing 521 position be rotatably supported at cam swing arm it is left,
The rear-swing arm 74 being slidably matched on right supporting disk 4,5 and with swing arm guide holder 71 is by rear-swing arm support shaft 742 respectively right
It is left and right cam swing arm should to be rotatably supported in the position of left supporting disk second bearing 441 and right supporting disk second bearing 531
On supporting disk 4,5, thus when the left and right supporting disk 4,5 of cam swing arm is rotated, front swing arm 73 and rear-swing arm 74 is driven mutually to meet the tendency of
It is dynamic, because the first cam curved surface 63 of the first roller of front swing arm 733, the first roller of rear-swing arm 743 and shedding cam 6 is configured to rolling
Dynamic pair（Contacted with the second cam curved surface 64）, thus with the change of cam curved surface, the pendulum driven by forward and backward swing arm 73,74
The rotation direction of arm guide holder 71 and corresponding angle also change, and make main shaft 3 by first, second cam curved surface 63,64
Stop when change is produced, when and move and meet and main shaft the links or shedding mechanism 10 supporting with main shaft（Fig. 2 shows）
Heald frame opening requirement.Because the shedding mechanism linked with main shaft 3 belongs to prior art, see, for example, CN1057352C and
CN101709525B（Three openings mechanisms of Rotated electric Dobby）, thus applicant repeats no more.
In summary, the technical scheme that the present invention is provided compensate for the shortcoming in prior art, favorably accomplish invention
Task, has faithfully cashed the technique effect referred in the superincumbent technique effect column of applicant.
