Description
(1) technical field
The utility model relates to field of textile machinery, and the jacquard weave that is specifically related to a kind of Rapier looms is leading with the eccentric wheel apparatus in the cylindrical fireworks transmission system.
(2) background technology
Rapier looms is the textile machine in a kind of industry that is widely used in weaving cotton cloth, range of application and field are all boundless in China's textile industry, closely during the last ten years, along with China loom manufacturing firm constantly carries out technological innovation to Rapier looms, at present the performance of Rapier looms is greatly improved, and Rapier looms can have been stablized at big reed width prerequisite lower main axis rotating speed and brings up to more than per minute 200 changes.Because Rapier looms needs the jacquard weave faucet device to come supporting realization for finishing of fabric fleuron, therefore for the jacquard weave tap, the rotating speed of its device also need be brought up to corresponding speed and could mate.The jacquard weave tap is a kind of compact conformation, transmission mechanism complicated apparatus, when cylindrical fireworks cooperate the reciprocating motion that the loom movement range does to move forward and backward, that just can carry out the jacquard weave tap lays one's hand on pin and needle selection, under the interoperation of upper and lower girff, the warp of carrying of finishing the whole loom course of work moves simultaneously.The linear reciprocating motion of cylindrical fireworks is the important process processes in the jacquard weave faucet system, generally by jacquard weave tap main shaft transferring power, rotate by the moving transverse axis that an eccentric wheel apparatus is housed of big pinion connecting band, eccentric wheel drives the adjusting rod that is connected on the eccentric wheel apparatus and pumps under the rotation of transverse axis, rocking beam of right angle and buffering connecting rod by adjusting rod drive girff upper end drives the straight reciprocating motion that the cylindrical fireworks work moves forward and backward again, finishes the interoperation of cylindrical fireworks in whole loom work system with this.Eccentric wheel apparatus is an important device in the jacquard weave faucet device, the operating frequency height, easy to wear, and to connecting having relatively high expectations of fastness, for this reason, provide a kind of and can accurately transmit the power that cylindrical fireworks are done straight reciprocating motion, have again connect the fastness height, eccentric wheel apparatus easy to maintenance is necessary very much.
(3) summary of the invention
The utility model provides a kind of jacquard weave of Rapier looms leading with the eccentric wheel apparatus in the cylindrical fireworks transmission system, and main technical schemes is as follows:
A kind of jacquard weave tap is used eccentric wheel apparatus, is made up of eccentric wheel sleeve seat, locking chuck, adjusting rod fixed cover, bearing, eccentric cam, bulging joining sleeve ring and swelling axle sleeve.Described eccentric wheel sleeve seat is provided with locking chuck and adjusting rod fixed cover at two ends of symmetry, locking chuck is the opening setting on the eccentric wheel sleeve seat, eccentric wheel sleeve seat inside also is provided with an end ring, after bearing is put into the eccentric wheel sleeve seat, by bolt locking chuck is tightened, bearing firmly can be fixed in the eccentric wheel sleeve seat.
Described eccentric cam is cam body and convex wheel body exceptionally, the external circle of cam ring is whole to be installed in the brearing bore, evagination wheel body and convex wheel body are eccentric and are provided with, the axis hole that transverse axis is installed is concentric setting on the cam body outside, on the convex wheel body, then be set for the eccentric, when the evagination wheel body rotates with transverse axis, can drive the circumference reciprocating motion that the eccentric wheel sleeve seat is made certain amplitude like this, drive adjusting rod with this and pump by the off-centre design of convex wheel body.Convex wheel body one side also is provided with a fixed pin holes, can use fixed pin shaft bolt and bearing cone positioning and fixing during installation.
Described bulging joining sleeve is equipped with an open slot, and is provided with six equally distributed screw holes on a side end face, and the bulging joining sleeve ring is whole to be positioned in the inner ring of evagination wheel body; Expansion shaft puts and is provided with fixedly connected ring and band tapered hub, whole device also is provided with an open slot, correspondingly on the fixedly connected ring be provided with six perforation, between two perforation, be provided with moving back of three dismounting usefulness again respectively simultaneously and pull out screw hole with screw hole on the bulging joining sleeve ring end face.
When the utility model is installed, earlier with bearing fixing in the eccentric wheel sleeve seat, convex wheel body with eccentric cam is fixed in the bearing cone again, and with a fixed pin shaft bolt with convex wheel body and bearing cone positioning and fixing, when whole eccentric wheel apparatus being installed on the transverse axis of jacquard weave tap, earlier the band tapered hub front portion of swelling axle sleeve is stretched in the bulging joining sleeve ring, again the bulging joining sleeve ring is placed the inner ring of evagination wheel body, and then transverse axis passed the swelling axle sleeve, because the mode of pulling out of moving back is adopted in the design of swelling axle sleeve, when swelling axle sleeve and bulging joining sleeve ring being tightened gradually with six fixed screws, be subjected to the swelling effect of the band tapered hub of swelling axle sleeve, the bulging joining sleeve ring outwards expands gradually, the inner ring of outer ring and evagination wheel body is tightly fixing, in like manner, the fixing contraction of band tapered hub and transverse axis owing to the band tapered hub that is subjected to constantly inwardly stretching into, mutual fixing also becomes more and more tightr, when last swelling axle sleeve and bulging joining sleeve ring after being completely fixed under the effect of six fixed screws, bulging joining sleeve ring and evagination wheel body, bulging joining sleeve ring and swelling axle sleeve, the transverse axis of swelling axle sleeve and jacquard weave tap is moved back by device to pull out design principle firmly to fix mutually.
Jacquard weave tap eccentric wheel apparatus described in the utility model, easy for installation, can be applicable to the cylindrical fireworks power transmission on the jacquard weave tap, because with being connected to have adopted to move back and pulling out fixed form of jacquard weave tap transverse axis, therefore need not carry out the processing of key pin to transverse axis and eccentric cam, be that the pressure that produces between the female surface of each part of utilization and frictional force realize the novel keyless joint of loading and transmitting, long service life, the intensity height, the swelling device convenient disassembly.
