Description
Technical field
The invention belongs to air-jet loom field, it is related to a kind of weaving machine rocking shaft bearing arrangement assay device and its test method,
For measuring rocker rolling bearing, the stress of bearing shell and the skew in bearing shell axle center hand in hand.
Background technology
Shake shaft-bearing system by rocker tilting member, rocker rolling bearing, crank and rocker mechanism, the hand in hand another portion such as bearing shell
Part forms, and rocker rolling bearing and hand in hand bearing shell are the main friction pairs of beating-up mechanism for loom.The workpiece of beating-up mechanism is
Reed, the power acting on reed is delivered to rocker by slay, lay sword, and rocker axle subjects whole effects of beating-up mechanism
Power and moment.Air-jet loom is when running up, although about 25 ° of rocker oscillation system pendulum angle, but latitude side caught by rocker
Rolling bearing and hand in hand bearing shell damage many, beating-up mechanism work reliability and service life with shake the close phase of shaft-bearing system
Close.The rotating speed more and more higher of air-jet loom, load is increasingly heavier, loom fabric width is more and more wider, shakes the building ring of shaft-bearing system
Border tends to severe, occurs in that a series of faults it is therefore necessary to shaft-bearing system test is shaken in research in system bearing bearing operation
Device, understands the running status of system bearings, the skew in measurement rocker rolling bearing and the hand in hand stress of bearing shell and rocker axle center
It is the element task in research.
The workpiece reed of beating-up mechanism completes beating and two actions of wefting insertion simultaneously, because reed is subject to the anti-of weft yarn
Active force, is subject to the jet wind action power of pilot jet, these power are all changeable over time and space again.In beating
Carve, weft yarn causes the vibration of rocker structure to the pulsating impact of reed；In non-beating moment, the connecting rod mechanism movement meeting of high speed
Produce dynamic equilibrium unstability, cause bending to combine vibration, vibration produces great destructive power, damage that the bearing that stands in the breach is unbalance.
2.8 meters of loom reed width, then rocker length surpass 3 meters, reed is with the axis of rocker for axial line reciprocally swinging, rocker
Operationally produce bending.When running up, slay oscillation system produces unbalanced load, and the load of rocker is periodically to become
Change, rocker produces Bending-Twist Vibrations, the magnitude of load bearing when rocker rolling bearing and hand in hand bearing shell work when bearing load
It is all time dependent with direction, thus BEARING SHAFT track is also time dependent.Make special rocker-bearing system
The assay device of system, the factors such as change, the weight of different reed width fabric, reed and slay of magnitude of load of can studying are to rocker
The impact of rolling bearing and hand in hand bearing shell, directly obtains data and the curve of bearing, to the improvement shaking the another part of shaft-bearing system
There is provided foundation with new design.
In order to allow weaving machine high-speed to operate, mechanical part must be lightweight, and lightweight part amplitude in vibration is big, rocker
Oscillation system complex structure, simple calculating hardly results in the accurate dynamic data of system, and the best way is to be tested by making
Platform, tests the dynamic characteristic of measuring system on testing stand, can conveniently change the parameter of various components, provides foundation for design.
