ABSTRACT:
A device for measuring the magnitude and direction of unbalanced moments about each of two mutually perpendicular axes resulting from the displacement of the center of gravity of an object being measured, such as a tire, from the third mutually perpendicular axis. The moment sensing portion consists of two pairs of strain gage-equipped beams, one pair coincident with each of the two axes, with the intersection of the three axes corresponding with the design center of gravity of the object being measured. The sensing head is mounted on a spherical air bearing whose center of curvature corresponds with the intersection point of the three axes, so that unbalanced moments tend to cause pivotal movement about the associated axis, as permitted by yieldable flexing of the beams, while the weight of the object being measured is exerted parallel to the third axis and against the air bearing, so that such force is bypassed around the moment sensing portion to avoid damaging or influencing the sensing structure.
