Abstract
The utility model relates to a rapier conveyer of a rapier loom, which is mainly composed of a rigid angle bar H1AH2, a conjugate cam, a space four bar linkage ABCD, a rocker compact disc, a sector gear, a fixed axle wheel train, a rapier wheel, a rapier belt and a rapier head. The utility model can be used for a rapier loom and improving the weft inserting speed of a rapier loom, having the advantages of simple structure and light weight.
Description
The utility model relates to a kind of Rapier looms, particularly rapier transmission device
The conjugate cam rapier transmission device that existing as shown in Figure 1 Rapier looms is used is mainly by rigidity dihedral bar H1AH2, conjugate cam, quadric chain ABCD, rocking bar CD, sector gear 2, fixed shaft wheel Z1, bevel gear Z2, Z3, sword wheel 3, sword belt 4, sword head 5 constitutes, this kind conjugate cam rapier transmission device is because the direction of motion of the quadric chain ABCD direction of motion and sword belt is 90 degree, thereby need a pair of bevel gear that the quadric chain ABCD direction of motion is altered course, so that drive the sword belt motion by the sword wheel, this device, because bevel gear Z2, the number of teeth of Z3 is identical, thereby can not pass through Z2, change rotating speed after the Z3 transmission, and there is complex structure in the bevel gear group, the shortcoming that cost is high.
Goal of the invention of the present utility model be to provide a kind of by drive gear speed change and simple in structure, cost is low, lightweight Rapier looms rapier transmission device.
The utility model is to realize like this, comprise rigidity dihedral bar H1AH2, conjugate cam, quadric chain ABCD, rocking bar CD, sector gear or tooth bar, fixed shaft gear train, the sword wheel, sword belt, the sword head, conjugate cam is positioned between rigidity dihedral bar H1AH2, the end of quadric chain ABCD and rigidity dihedral bar rigidity are joined, rocking bar CD among the quadric chain ABCD then with the sector gear loose joint, sector gear is then meshing with fixed shaft gear train, the output of fixed shaft gear train then joins with the sword wheel, wherein quadric chain ABCD is a space four bar linkage mechanism, fixed shaft gear train can be made of a travelling gear and a pair of driving gear set, and the sword wheel is connected with the output wheel of driving gear set.During use, conjugate cam makes rigidity dihedral bar H1AH2 make reciprocally swinging, because fork AB and bar H1AH2 are rigidly connected, make reciprocally swinging by space four bar linkage mechanism ABCD driving and rigidly connected sector gear of rocking bar CD or tooth bar, driving travelling gear and driving gear set rotates, the amplification of taking turns by the sword that is connected with the output wheel of driving gear set at last makes the sword belt acquisition linear reciprocating motion meshing with the sword wheel.
Here, driving gear set can be a pair of change-speed gearing, like this, amplifies through two-stage, can improve the linear reciprocating motion of sword belt greatly.
The utility model is compared with the prior art owing to adopted space four bar linkage mechanism, so just need not be pass to sword wheel, sword belt by the swing that space four bar linkage mechanism will be taken turns with sword, the direction of motion of sword belt is the rigidity dihedral bars of 90 degree by bevel gear, replace bevel gear with driving gear set, like this, can change the running speed of sword wheel, sword belt by driving gear set, because driving gear set can be that the pair of straight gear also can be a belt pulley, these driving gear set all than bevel gear group simple in structure, cost is low, in light weight, transmission efficiency is high.
Fig. 1 is the organigram of existing conjugate cam rapier transmission device;
Fig. 2 is an organigram of the present utility model.
Now reaching embodiment in conjunction with the accompanying drawings is described in further detail the utility model:
The utility model mainly is made of rigidity dihedral bar H1AH2, conjugate cam 1, space four bar linkage mechanism ABCD, rocking bar CD, sector gear 2, travelling gear 3, a pair of change-speed gearing 7, sword wheel 4, sword belt 5, sword head 6, conjugate cam 1 is positioned between rigidity dihedral bar H1AH2, the end of quadric chain ABCD and rigidity dihedral bar rigidity are joined, rocking bar CD among the quadric chain ABCD then with sector gear 2 loose joints, 2 of sector gears are meshing with travelling gear 3, and the output wheel 8 of a pair of change-speed gearing 7 joins with the sword wheel.
Claims (2)
