GEAR MEASURING LINEAR AND ANGULAR MOVEMENTS Russian patent published in 1997 - IPC

FIELD: measurement technology, measurement of linear and angular movements in mechanical engineering, in machine tool manufacture and in robotics. SUBSTANCE: gear measuring linear and angular movements has measurement raster 1, two reading channels composed of illuminators 2, indication rasters 3 conjugate to measurement raster, photodetectors 4. Signal from outputs of photodetectors 4 goes through formers 5 to inputs of decoder 6 which outputs are connected to inputs of R flip-flops 7,8,9. OR-ELSE gate 10, inverter 11, one-shot multivibrator 12, AND circuit 13 provide for formation of counting pulse of coordinates which goes to input of reversible coordinate counter 14. In this case errors in determination of coordinate are excluded by multiple reversing of directions of movement and vibrations of raster. Generator 18 of counting pulses, counter 16, register 15 storing durations of time intervals provide for measurement of durations of time intervals between comings of counting pulses of coordinates which is necessary for operation of unit 17 for determination of coordinate, velocity and acceleration for specified time moment. EFFECT: widened functional capabilities of gear. 2 dwg
