Description
Technical field
The present invention relates to a kind of rocker in loom field, in particular to a kind of anti-rocker of turning round.
Background technology
The slay oscillation system of beating-up mechanism has been concentrated most quality of the system of beating up, and reed is the axial line reciprocally swinging with the axis of rocker, and when running up, the slay oscillation system produces unbalanced load, and rocker produces the bending vibration when bearing load.
The workpiece reed of beating-up mechanism is finished simultaneously and is beaten up and two actions of wefting insertion, because reed is subjected to the reaction force of weft yarn, is subjected to the jet wind action power of pilot jet again, and these power all are changeable on time and space.It is very complicated to the effect of reed and rocker to beat up, and is beating up constantly, and weft yarn can cause the rocker structural vibrations to the pulsating impact of reed; Beat up constantly non-, connecting rod mechanism movement at a high speed can produce the dynamic equilibrium unstability, causes that bending unites vibration, and vibration produces great destructive power.The rotating speed of jet loom is more and more higher, and the vibration of reed is strengthened thereupon, torsion Vibration, prevents that the rocker fatigue fracture from being the top priority of rocker.
Rocker is the parts that length is the 2000-4000 millimeter, and rocker is made reciprocally swinging around axis, ± 12 °-± 15 ° approximately of pendulum angles, and when rocker drive slay was flapped toward fell, reed was squeezed into fell with weft yarn.
In beating-up mechanism motion, reed is squeezed into fell with weft yarn, beats up in one minute to reach thousands of times, and in the process of beating up, rocker is constantly crooked and reverse.The workpiece that beats up is a reed, the power that acts on the reed is delivered to rocker by slay, lay sword, especially to the loom of the above reed width of 280CM, the motion of master end and passive side is asynchronous, the master end action is preceding, the action of passive side after, rocker twists repeatedly as a result, fatigue fracture in the middle of causing.
Summary of the invention
