Description

Dobbies cam gear

Technical field

The utility model 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 drives shedding above and below the heald frame of loom with this One of loom opening features of motion, dobbies are divided into two kinds of passive type and positive type by the difference of its opening form.

Foregoing negative dobby, its critical piece such as motion mode of broaching tool, push broach and drag hook show as back and forth transporting 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 are as the aforementioned The motion mode of broaching tool, push broach and drag hook shows as rotary motion and uses connecting rod time comprehensive, can make up negative dobby 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, gained ground to reducing 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 because the patent application scheme is the transformation for crank-rocker style electronic jacquard machine And propose（See the 0002nd to 0004 section of specification）, thus before driving the cam swing arm of the structural system of cam gear, 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 to dobbies cam gear, then extremely The drawbacks of following two aspects can be 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 can claim " driving gear "）And by moving The supporting disk drive gear that power input shaft gear drives（Also can claim " driven gear "）The same of shield is covered by casing in receiving to casing When by the 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, be changed to only by foregoing power input shaft gear and supporting disk drive gear by the external of prior art in 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, because transmission link for example needs to input through lower tooth roller box power successively more 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 drive transition axis, propped up before driving cam swing arm by the transition axis fixed with cam swing arm front support disk Tray, by cam swing arm front support disk drive a pair simultaneously and conjugate cam（Also can claim " shedding cam ", it is as follows）Wheel rim （Conjugate cam curved surface）Form rolling pair and the unidirectional seat of the swing arm with being fixed on main shaft forms 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 The drawbacks of being made up on the basis of prior art in prior art and the rational dobbies cam gear of design structure, which have, to be accumulated Pole meaning, technical scheme described below are caused under this background.
