Abstract:
1. A torque measuring instrument comprising: torque transfer means for transmitting torsional force about a torque axis; first support means secured to said torque transfer means for angular displacement about said axis by transmitted torque; second support means adjacent to said first support means; first linkage means between said first and second support means having a first displacement segment that translates in a first direction parallel with said axis upon angular displacement of said first support means relative to said second support means; second linkage means between said first and second support means having a second displacement segment that translates in a second direction substantially parallel with said axis upon angular displacement of said first support means, said second direction being substantially opposite of said first direction; first sensor support means secured to said first displacement segment; second sensor support means secured to said second displacement segment; sensor means disposed between said first and second sensor support means to detect spatial displacements between said first and second sensor supports substantially parallel with said axis; means for determining a value of said spatial displacement, and, means for relating the value of said spatial displacement to the value of transmitted torque.
