ABSTRACT:
A flexure hinge assembly comprising a pair of fixed telescopes inner and outer tubular members separated into at least one driving portion, at least one gimbal portion and at least one driven portion and a plurality of flexure blades all formed by a plurality of slots and apertures through the walls of each tubular member. Flexure blades are formed by pairs of adjacent apertures with the slots interconnecting apertures to separate the tubular members into the driving, gimbal, and driven portions. A pair of diametrically opposed flexure hinges, each comprising two mutually orthogonal flexure blades one in the outer and one in the inner member, connect each gimbal portion to the driving portion. Another such pair of flexure hinges connect each gimbal portion to the driven portion.
The common plane of flexure of two of the four flexure blades of each tubular member forms a first angle with respect to the common axis of the inner and outer tubular members, the common plane of flexure of the two other flexure blades of each tubular member forms a second angle with respect to the common axis of the inner and outer tubular members, and the difference between the first angle of two flexure blades of each member and the second angle of the other two flexure blades of that member being substantially 90.degree..
The crossed flexure blades are fabricated by forming the apertures with the inner and outer tubular members coaxially aligned in a first relative angular position and then rotating the tubular members with respect to one another through a predetermined angle of rotation into a second relative angular position of the tubular members to create four flexure hinges spaced 90.degree. apart.
