Abstract
A coupling comprises blade flexures that connect two end members through which control rods extend to cross members that are attached near the mid-points of the blade flexures, providing stable-linear load reaction means for use as end pivots for linkages where stick-slip motion is undesirable. The blade flexures are housed in a rigid cage comprising four separators that are attached to end members, and the flexures are attached to the end members by the separators.
Claims3
A coupling, comprising:
- a first member normal to a load axis;
- a second member normal to said load axis at a first distance from the second member;
- an aperture in said first member on said axis;
- an aperture in said second member on said axis;
- a first pair of flexures comprising first and second flexures connecting said member, said first and second flexures being parallel to said axis and diametrically opposed;
- a second pair of flexures comprising third and fourth flexures connecting said members, said third and fourth flexures being parallel to said axis and diametrically opposed;
- a first cross member normal to said axis and connected near the midpoints of the first and second flexures;
- a first rod along said axis and extending through the aperture in said first member and attached to said first cross member;
- a second cross member normal to said axis and connected near the midpoints of the third and fourth flexures;
- and
- a second rod along said axis and extending through the aperture in said second member and attached to said second cross member.
