Description
Известен способ уменьшени диаметров кодовых дисков фотоэлектрических кодирующих устройств.There is a method for reducing the diameters of the code disks of photoelectric encoders.
Предлагаемый способ уменьшени диаметров кодовых дисков указанных устройств отличаетс тем, -что кодовые маски нанос т на два диска, размещенных на общей оси. На одном диске нанос т одну часть Кодовых дорожек, на втором-другую. Это позвол ет уменьшить поперечные размеры фотоэлектрических кодирующих устройств.The proposed method for reducing the diameters of the code disks of these devices differs in that code masks are applied to two disks placed on a common axis. On one disc one part of the Code tracks is applied, on the second or the other. This allows the transverse dimensions of the photovoltaic encoders to be reduced.
На общей оси 1 (см. чертеж) жестко закреплены два кодовых диска 2 одинаковых диаметров. На одном диске нанесены кодовые зоны старших раз:р дов, на другом-младщих. Возможно также расположение .всех четных разр дов на одном кодовом диске и всех нечетных на другом. При такой схеме диаметры кодовых дисков определ ютс из соотношени :On the common axis 1 (see drawing) two code disks of 2 identical diameters are rigidly fixed. On one disk, the code zones of the senior times are marked: rows, on the other - younger ones. It is also possible to arrange all the even bits on one code disk and all odd ones on the other. In this scheme, the diameters of the code disks are determined from the relation:
Z) D.v + 2S(- + l),Z) D.v + 2S (- + l),
где Длг - диаметр кодовой дорожки самого старшего разр да;where Dlg is the diameter of the highest-order code track;
S -ширина кодовой дорожки;S is the width of the code track;
N -число двоичных разр дов.N is the number of binary bits.
При четном числе двоичных разр дов вместо N беретс число, на единицу большее. Диаметры дисков в данном случае уменьшаютс до 40%.For an even number of binary bits, instead of N, a number is taken, one greater than. The disc diameters in this case are reduced to 40%.
Между кодовыми дисками 2 установлен источник 3 света. Поток СЕзета, проход через прозрачные сегменты кодовых дисков и щелевые диафрагмы 4, попадает «а фотодатчики 5, располон :енные на одной линии, (Направленной по радиусу диска.A light source 3 is installed between the code disks 2. The CEZET flow, passage through the transparent segments of the code discs and the slit diaphragms 4, falls on the photosensors 5, which are open: on the same line, (Directed along the radius of the disc.
