ABSTRACT:
A gyroscopic force measuring cell has a frame having a gyroscope suspended force-free therein with an inner gimbal and an outer gimbal, a force indicent at the rotational axis of the gyroscope and generating a torque producing a precessional motion about the precessional axis, the motion exhibiting a velocity which is proportional to the incident force and being a measurement thereof. The measuring cell has a linkage for force initiation from a non-co-precessing load pickup through a co-precessing transmission element disposed in a pivot bearing along the precessional axis, the pivot bearing being linked to a pivot bearing housing so as to be coaxially movable in guides relative to the precessional axis. The transmission element is a shaft seated in the pivot bearing having a substantially radial load arm and an element for force transmission connecting the load arm to the inner gimbal, the load arm, the element for force transmission, the rotational axis and the precessional axis being in substantially one plane.
