Technical field
The present invention relates to a kind of Rapier looms, especially relate to a kind of sword belt of Rapier looms or drive unit of arrow shaft of being used for.The loom type technical field that belongs to textile machine.
Background technology
In the prior art, the wefting insertion process of Rapier looms all is to make the sword head of relative linear reciprocating motion by two along loom reed width direction, the shed open central authorities handing-over weft yarn from the both sides of loom setting in motion to loom, and then return to the both sides original position, thereby finish wefting insertion one time.Wherein, the sword head is fixed on sword belt or the arrow shaft, and the perforation on sword belt or the arrow shaft is driven by being meshed with tooth on the sword transmission wheel, and perhaps smooth sword belt end is fixed on the sword transmission wheel, is driven by sword transmission wheel.The sword belt of Rapier looms or the key function of driving device in rapier are that the uniform speed rotation with main shaft converts to and the perpendicular sword transmission wheel axle of main shaft and the oscillating motion of sword transmission wheel, and then convert the linear reciprocating motion of sword belt or arrow shaft and sword head to.
The form of the sword belt of Rapier looms employing both at home and abroad or driving device in rapier mainly contains the secondary composite set of four connecting rods or six connecting rods and bevel gear, conjugate cam and connecting rod and the secondary composite set of bevel gear, space connecting-rod and four connecting rod assembly devices and spiral shell revolute and linkage composite set etc. at present.Wherein, first three is planted, and drive unit is oversize, and transmission link is many, and number of spare parts is many, manufacturing cost is high, the Installation and Debugging difficulty is big; In then a kind of spiral shell revolute and the connecting rod assembly device, the accuracy of manufacture of varying pitch screw requires high, and material requires also high, and technology difficulty is big, makes the manufacturing cost height.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of simple in structure, compact, part processing is convenient, cost is low, the sword belt stroke is easily transferred the sword belt that is used for Rapier looms or the drive unit of arrow shaft are provided.
The object of the present invention is achieved like this: a kind of sword belt of Rapier looms or drive unit of arrow shaft of being used for, comprise main shaft, crank and rocker mechanism, shaft gear and sword transmission wheel, shaft gear is coaxial with sword transmission wheel, and described crank and rocker mechanism comprises crank, reel cage, pendular body and sector gear
Described crank is fixedlyed connected with main shaft, and reel cage links to each other with crank with slide block by rolling bearing, and pendular body links to each other with reel cage by rolling bearing, installs sector gear on the pendular body,
Direct and the shaft gear engagement of described sector gear, or sector gear and gear pair engagement, gear pair and shaft gear engagement,
The central axis of the central axis of described main shaft, the pivot center of reel cage, pendular body and the oscillation center of sector gear all intersect at the same intersection point in space,
Angle greater than zero degree is arranged between the pivot center of described reel cage and the central axis of described main shaft.
The course of work of the present invention is: the at the uniform velocity rotation of main shaft causes that crank rotates, because reel cage is connected with crank by rolling bearing, slide block, reel cage is connected with pendular body by rolling bearing again, therefore the line of reel cage two rolling bearing axis is around the axis swing of pendular body, thereby drive the swing of pendular body and sector gear,, can adjust the crossing angle of reel cage and main shaft by slide block and screw, thereby regulate the amplitude of fluctuation of sector gear, change the stroke of sword belt; Simultaneously, slide block can guarantee the homocentric of reel cage and main shaft with being connected of crank.
The crank and rocker mechanism that the present invention utilizes crank, reel cage, pendular body and sector gear to constitute converts the uniform rotation of main shaft to the oscillating motion of the sector gear vertical with main shaft, amplify the amplitude of fluctuation of sword transmission wheel by gear, realized the linear reciprocating motion of sword belt or arrow shaft and sword head, simultaneously can regulate the stroke of sword belt or arrow shaft easily, simple and compact for structure, driving-chain is short, and appearance and size is little, motion stabilization is reliable, and part processing is convenient, cost is low.
Hereinafter in conjunction with corresponding accompanying drawing the present invention is described, Fig. 5 to Figure 12 represents nonrestrictive most preferred embodiment, and people can carry out the improvement of technology or structure to it, but does not all break away from the scope of the present invention that Fig. 1, Fig. 2, Fig. 3, Fig. 4 are contained.
