The invention discloses a device and method for testing stress on loom rocking shaft bearing equilibrium structure systems. The device comprises a tester mechanical component, a working condition simulation component, a box body stress measuring device, a rocking shaft driving torque measuring device and a main shaft rotation unevenness measuring device; rocking shafts which have different structures or are supported in different ways are adopted to construct four different types of rocking shaft bearing equilibrium structure systems respectively; rubber strips of different thicknesses are adopted to simulate the load of a loom; the rotating speeds of the rocking shafts are changed by a frequency converter; the conditions of rocking shaft driving torque, box body stress and main shaft rotation unevenness under different conditions are measured respectively. The device provided by the invention can quantificationally study the influence of load change and rotating speed on the rocking shaft driving torque, box body stress and main shaft rotation unevenness of equilibrium structures which have different forms and different support ways, directly obtains data and curves through the measuring devices at measuring points, and provides a basis for the structural improvement and the new design of the rocking shaft equilibrium systems.
Description
technical field [0001] The invention belongs to the field of air-jet looms, and relates to a device and method for a force test of a rocking shaft bearing balance structure system of a loom, which is used for measuring the rocking shaft transmission torque and the uneven rotation of the main shaft of the rocking shaft bearing balance structure system with different structures and the impact force on the box. Background technique [0002] The rocker shaft bearing balance structure system is composed of rocker shaft swing parts, rolling bearings, crank rocker mechanism, hand bearing bush and other components. The working part of the beating-up mechanism is the steel reed, and the force acting on the reed is transmitted to the rocking shaft through the sley and the sley foot, and the bearing balance structure system of the rocking shaft bears all the forces and moments of the beating-up mechanism. When the air-jet loom is running at high speed, although the swing angle of the ...
