Abstract

Inventia se refera la o metoda si un aparat pentru masurarea momentului la masa rotativa, care urmareste raportul valorilor turatiei în doua puncte aflate pe lantul de antrenare a mesei rotative, unul situat la intrarea convertizorului hidraulic de cuplu si celalalt pe axul cardanic ce antreneaza masa, folosind doua traductoare de turatie ale caror semnale de iesire sunt prelucrate de circuite de formare, urmate de un bloc de calcul al raportului valorilor turatiei în cele doua puncte de masura obtinut în cod zecimal-binar, ce se aplica paralel unui convertor digital analog si mai departe, unui circuit de împartire, la iesirea caruia se obtine un semnal proportional cu momentul rezultant al mesei rotative, semnal ce actioneaza un instrument indicator si, în final, un circuit de semnalizare a depasirii unei limite prestabilite.The invention relates to a method and apparatus for measuring the torque at the rotating table, which follows the ratio of the speed values in two points on the rotating table drive chain, one located at the entrance of the hydraulic torque converter and the other on the cardan shaft which drives the table, using two speed transducers whose output signals are processed by the training circuits, followed by a calculation of the ratio of the speed values in the two decimal points to the binary code, which is applied in parallel to an analogue digital converter and more away, a splitting circuit, at the output of which a signal proportional to the resultant moment of the rotating table, a signal acting on an indicator instrument and finally a signal circuit for exceeding a predetermined limit is obtained.
