Abstract

"PROCESSO E DISPOSITIVO PARA DETERMINAçãO DO TORQUE EM EIXOS DE TRANSMISSãO". A invenção refere-se a um processo e a um dispositivo para determinação do torque em eixos de transmissão, caracterizado pelo fato de que, com uma relação de mudança de velocidade constante, os números de rotações de um primeiro eixo de transmissão (2, 19) e de um segundo eixo de transmissão (3, 22) são medidos ciclicamente, sendo que no primeiro eixo de transmissão (2, 19) está presente um primeiro torque e no segundo eixo de transmissão (3, 22) um segundo torque, e o segundo eixo de transmissão (3, 22) é direta ou indiretamente acionado pelo primeiro eixo de transmissão (2, 19) através de rodas dentadas (5, 6, 7, 8; 20, 21), sendo que desses dois números de rotações é calculado um quociente e, em seguida, memorizado; depois o quociente atual é comparado com o quociente de uma medição prévia bem como, com uma diferença entre o quociente da medição atual e o da medição prévia, é concluída uma alteração do torque do primeiro eixo de transmissão (2, 19).
