METHOD OF MEASUREMENT OF SHAFT DEFORMATION Russian patent published in 2014 - IPC G01B5/20 

FIELD: textiles, paper.

SUBSTANCE: invention relates to the field of dyeing and finishing production of textile industry, and can also be used in the pulp and paper, printing, chemical and other industries, where roller equipment is used. The claimed method of measuring the deformation of shafts, which consists in determining the deformation of the shaft by means of a measuring device driven into contact with the generator of the shafts, their loading, and the shafts are grasped tightly along the whole of their working width with the polymeric tape, it is fixed rigidly on both sides of the machine housing along the whole length of the shafts, the position of the polymeric tape is fixed on the working surfaces of shafts in mutually perpendicular axial planes with use of a rod with supports and two plates placed in parallel to each other and perpendicular to the rod along its edges, using which the change in the required value of the pressure load and the position of the device in horizontal or vertical planes perpendicular to the axis of the shaft are adjusted by means of the adjusting slots on them, thus eliminating the flexing and distortion of the measuring device, and the stop screw and the rod of the measuring device rest on the tape, leaving a gap of 2-3 mm for providing the ability for setting on a zero mark of the scale of the measuring device or setting initial values for measuring the deformation of working surfaces of the shafts, then the shafts are loaded, for each value of the load the readings of the measuring device are taken, according to the difference readings at zero or initial and predetermined load the amount of total deformation of the working surfaces of the shafts is determined.

EFFECT: improving the accuracy and reducing the time of detection of deformation due to the simultaneous measurement of total deformation of all shafts involved in spinning.
