Abstract
ROLAMENTO. A presente invenção trata de um rolamento que compreende pelo menos um sistema de determinação da amplitude A das deformações pseudo sinusoidais de uma área (7) do anel fixo (1) induzidas durante a rotação, e o referido sistema compreende quatro tensómetros (8), um dispositivo de medida de quatro sinais V~ i~função respectivamente das variações temporais do sinal emitido por cada tensómetro (8), sendo o referido dispositivo está apto a formar dois sinais respectivamente SIN e COS com o mesmo ângulo e a mesma amplitude, e um dispositivo de cálculo da amplitude A das deformações da área (7) em função do tempo, dispositivo esse que está disposto para calcular a expressão SIN¬ 2¬ + COS¬ 2¬ de modo a deduzir dela a amplitude A.
