Abstract

The invention relates to a measurement technique and can be used to control linear and angular movements of shafts and other parts. The aim of the invention is to expand the field of use by using a telescopic sensing element that is hinged to a monitored shaft and having a calibrated orifice made at an angle to the longitudinal axis of this element. When measured, depending on the wear of the supports of the monitored shaft 9, its free end moves, which is transmitted through the spherical support 6 to the cup 2 fixed on the suspension from springs 10 and converted into offset of the calibrated orifice 12 with scale 11 relative to the source 13 of the radiation and into change signal at the output of the photosensitive element 14. 1 Il.

The invention relates to a measuring technique and can be used to control linear and angular movements of shafts and other parts,

The purpose of the invention is to expand the scope.

The drawing shows a diagram of a photoelectric sensor for moving a part,

| The sensor includes a housing 1, installed: a sensitive element inserted into it, made in the form of a cup 2, g t1 of springs which are recursively installed in it, and a plunger 4, fixed at the ends of the plunger 4 and a cup 2 of spherical supports 5 and 6, is designed for contact, respectively, with the bolster 7 and with the rotating i..jj in the support bearing 8, controlled by a vap 9, uniformly and radially fixed by the ends alone on the cup 2 of the springs 10, the other ends of which are fixed on the housing 1, and 11 fixed to the cylindrical surface of the glass 2 concentric a calibrated hole 12, whose axis intersects the axis of the cup under ugloy 2 35-50; the optically coupled radiation source 13 and the photosensitive element 4 and the reading / recording unit, made in the form of an amplifier 15, an execution unit 16, and a reading unit

block 17.

The sensor works as follows

I In the initial state, the luminous flux from the radiation source 13 propagates along the axis of the calibrated -. the holes 12 and illuminates the photosensitive element 14, while the executive 16 and 17 counting blocks fix the initial position of the monitored shaft 9. When the shaft 9 rotates, depending on the wear of its supports, it moves, through the spherical support 6

is given to the cup 2 and converted into an offset of the calibrated orifice 12 relative to the source 13 of the radiation and to a change in the signal at the output of the photosensitive element 14, which is converted into the reading of the reading unit 17. With unacceptable displacements of the shaft 9, the actuator 16 if necessary, one can visually observe the magnitude and direction of the displacement of the shaft 9 according to the position of the light beam from the source 13 of radiation, Springs 10 and the spherical support 6 exclude the rotation of the cup 2.
