Description
Technical field
The utility model relates to technical field of textile machine, relates to a kind of direct drive transmission of loom specifically.
Background technology
Present loom transmission drive mainly adopts by phase asynchronous alternating current generator passes through the belt transmission main shaft, and main shaft is controlled the quick startup of loom through one group of electric clutch-brake and stopped, when loom is weaved; Main shaft is connected in adhesive through electromagnetic clutch; The motor-driven complete machine runs up, and when needs stopped, electromagnetic clutch broke off transmission; Electromagnetic brake fast braking simultaneously, thus the running of complete machine stopped.When needs are sought the staplings yarn, drag complete machine by an independent motor through a group electromagnetic clutch and do complete cycle microinching forward or backwards.
The complex structure of said apparatus, simultaneously, because clutch can produce mechanical wear in the work that does not stop; Therefore need adjustment regularly or replacing; Safeguard, the maintenance work amount is big, simultaneously, this device change speed can only rely on the diameter of artificial replacing belt pulley to realize; Troublesome poeration, and can not adapt to the speed change in weaving.In addition, when caused by loom stop, motor is still in idle running, and while electromagnetic clutch etc. are also at lasting consumed energy, so energy waste is bigger.
Chinese patent CN1997785 has announced a kind of main drive that is used for loom, and it is by a driving wheel by main drive motor, and this driving wheel moves axially between at least two operating positions, the quick startup of loom and stop to be accomplished by motor.In reality is implemented; Main drive motor adopts the motor of magnetic resistance principle operation; Because the design principle problem,, there are very big pulsating nature and vibrations, noise in driven at low speed though reluctance motor has advantages such as simple in structure; Control simultaneously is complicated and do not have ripe control system, influences system implementation and popularization.This system is when the conversion of two positions simultaneously, because the energising of motor coil, axial electromagnetic force that can be certain to the axial generation of motor must rely on hydraulic pressure strength or other external force to overcome.

The rotor axis of electric that also can adopt of motor described in the utility model can be made the motor of axial displacement campaign with respect to motor stator; Specifically:, thereby guarantee that rotor axis of electric does not exceed the effective magnetic field scope under the different working position because the effective magnetic circuit of stator of this type of motor is greater than the rotor effective magnetic circuit length.The bonnet of said motor is provided with the backspacing a position detecting sensor that matches with the rotor shaft rear end.
The drive unit that moves axially described in the utility model adopts hydraulic jack as drive unit, and the piston rod end of said hydraulic jack combines with the end of rotor axis of electric through bearing, axle sleeve and connecting bolt; On the piston rod of hydraulic jack, connecting plate is installed; The spacing bearing pin of level to the cantilever design of the gear one side extension of beating up is installed on connecting plate, on the end face of gear that beat up, is provided with two spacing bearing pin mounting holes that match with spacing bearing pin respectively at least with respect to a side of spacing bearing pin.
The utility model is equipped with the reach position-detection sensor that matches with the connecting plate side on the cylinder body of said hydraulic jack.Axle head at the gear shaft of said opening gear is connected with angular transducer.
The wheel tooth ends that is fixedly installed on the driving gear on the rotor axis of electric described in the utility model is provided with chamfering.
The operation principle of the utility model is following:
The gear that beats up described in the utility model links to each other with the cam beating device and the wefting insertion driving mechanism of loom both sides, and the opening gear links to each other with shedding motion; Move in former and later two operating positions through moving axially drive unit drive motors armature spindle, promptly can drive the opening gear simultaneously and drive the motion of complete machine, also can accomplish the forward or reverse motion by single driving opening gear with the gear that beats up.
Specifically: shift to the back during one station when moving axially drive unit pushing motor armature spindle; The gear that beats up is in the disengaging engagement through arc groove B and motor driving gear, and meanwhile, the spacing bearing pin that is arranged on the connecting plate moves towards the gear direction of beating up under the drive of piston rod; And insert in the corresponding spacing bearing pin mounting hole that processes on the gear that beats up; The gear that beats up is fixed, to prevent its unintentional rotation, at this moment; The motor driving gear only with the opening gears engaged; Drive shedding motion and accomplish specified action, and the feedback signal of the angular transducer of the gear shaft axle head through being arranged on the opening gear, accurately control the position of motor rotation.
When moving axially drive unit pushing motor armature spindle and shift to last station; The gear that beats up gets into engagement through arc groove B and motor driving gear, and meanwhile, the spacing bearing pin that is arranged on the connecting plate is made reverse displacement movement under the drive of piston rod; And withdraw from the corresponding spacing bearing pin mounting hole that processes from the gear that beats up; Break away from the gear that beats up, at this moment, the motor driving gear is in the duty that is meshed with beat up gear and opening gear simultaneously; Driving beating device and weft inserting apparatus, shedding motion shedding motion are worked simultaneously; Realize the action of relevant provisions---start fast and carry out high speed motion and stop with the location, when weft breakage occurring, loom should be able to the realization of single driving shedding motion be goed around or the action of the searching broken yarn head that changes more; Loom can drive complete machine with manner of execution at a slow speed.
The beneficial effect of the utility model is following:
The device of the utility model can be accomplished switching and the quick start and stop of loom of two kinds of operating positions of loom, overcomes existing drive system in defectives such as the pulsation of driven at low speed, vibrations, noises.
