Description
Technical field
What the present invention relates to is a kind of slow train drive system of jacquard weaving machine, belongs to the fabric manufacture equipment in field of textile machinery and weaving process technology.
Background technology
Current jacquard weaving machine, the harness motion of warp thread is driven by jacquard, the reply action of harness motion is by Spring driving, therefore the opening driving force of the opening driving force ratio dobbies of jacquard is large, and during harness motion, jacquard needs the elastic force overcoming warp tension and returning spring.The power of jacquard is from the jacquard weave transmission system of loom, comprise in whole jacquard weave transmission system and seek latitude and microinching function, high-grade jacquard weaving machine all seeks latitude and microinching function, proper motion, seek latitude motion, microinching switching by loom seek latitude clutch and at a slow speed the effective action of clutch coordinated.In the jacquard weaving machine that high sley is brought up again, seek latitude clutch, at a slow speed wrong operation of motor frequent, major failure is slipping of clutch at a slow speed, seek the faults such as latitude clutch is out of supply, reason is that the bearing capacity of clutch is inadequate.For clutch at a slow speed, design in the past generally takes the diameter strengthening clutch friction face to improve the bearing capacity of clutch at a slow speed.Along with the warp thread number of jacquard weaving machine constantly increases, the rubbing surface diameter of clutch constantly increases.For the jacquard weaving machine of warp thread number more than 25000, or line pin number is more than the jacquard weaving machine of 5000 pins, takes the diameter strengthening rubbing surface to there is difficulty.On the one hand by the restriction of space structure, on the other hand enlarged diameter to a certain extent after, manufacture difficulty sharply increases, and the flatness of rubbing surface is difficult to ensure, has had a strong impact on the raising of the bearing capacity of clutch at a slow speed.Therefore for this kind of loom, a lot of unit takes cancellation to seek latitude, microinching function solves, and have impact on the adaptation of product of loom and the automatization level of loom.
Figure 1 shows that the structural representation of prior art, shown in figure: the output shaft fixed connection of gear 14 and alternating current generator 1, gear 2 and worm screw 16 are connected, worm gear 15, at a slow speed clutch rotor 5 and worm-wheel shaft 17 are connected, clutch armature 6, synchronous pulley 8, bevel gear 9 are connected with transverse axis 13 at a slow speed, and bevel gear 11 and vertical shaft 10 are connected.Worm gear case 3 and vertical shaft box 12 are connected.Gear 14, worm screw 15, worm-wheel shaft 17 are connected with worm gear case 3 by bearing H, F, G, D, E, and clutch coil 4 and worm gear case 3 are connected at a slow speed; Transverse axis 13 is connected with vertical shaft box 12 by bearing B, C, and vertical shaft 10 is connected with vertical shaft box 12 by bearing A.Gear 14 engages with gear 2, and worm screw 16 engages with worm gear 15, and bevel gear 9 engages with bevel gear 11.Clutch coil 4, at a slow speed clutch rotor 5, at a slow speed clutch armature 6 form clutch at a slow speed at a slow speed.Alternating current generator 1 is energized, clutch rotor 5 is at a slow speed driven to rotate by gear 14, gear 2, worm screw 16, worm gear 15, after clutch coil 4 is energized at a slow speed, clutch armature 6 and clutch rotor 5 adhesive at a slow speed at a slow speed, clutch armature 6 is at a slow speed driven to move, drive vertical shaft 10 to move by bevel gear 9, bevel gear 11 simultaneously, thus drive jacquard motion.The miscellaneous part of loom is driven to move by synchronous pulley 8, Timing Belt 7.During loom proper motion, main shaft move through Timing Belt 7, synchronous pulley 8 drives transverse axis 13 to rotate, and drives vertical shaft 10 to move by bevel gear 9, bevel gear 11, thus drives jacquard motion, now clutch coil 4 power-off at a slow speed, clutch armature 6 and clutch rotor 5 are at a slow speed thrown off at a slow speed.Main shaft drives clutch armature 6 at a slow speed to rotate simultaneously.The rotating speed of synchronous pulley 8 is consistent with loom main shaft rotating speed, and loom seeks latitude once, and clutch armature 6 rotates a circle at a slow speed.
The design feature of above-mentioned prior art is: 1), at a slow speed clutch armature and synchronous pulley be connected, the rotating speed of clutch armature is consistent with loom rotating speed at a slow speed.When jacquard weave power is larger, clutch armature and skidding between clutch rotor at a slow speed at a slow speed, cannot normally work;
2), the output shaft of alternating current generator 1 and gear 14 are connected.
