摘要

A support arrangement (10) which allows pivoting of a non-rotatable shaft (12) has a flexure structure (16) and a pair of axially-displaced inner and outer hubs (18, 20) respectively connected to, and disposed inwardly and outwardly of, the flexure structure (16). The flexure structure (16) is composed of disk-shaped flexural elements (30, 32, 34) disposed in stacked, axially spaced relation to one another and connected peripherally one to the next. The flexural elements (30, 32, 34) together define a frictionless, laterally stiff, fulcrum or pivot point (14) about which the shaft (12) can pivot through a predefined range of angular motion. The inner hub (18) is attached to an inner end one of the flexural elements (30) at an interior peripheral edge (52) thereof, whereas the outer hub (20) is attached to an outer end one of the flexural elements (32) at an exterior peripheral edge (56) thereof. The shaft (12) extends axially through the bores (22, 24) in the hubs (18, 20) and an opening (26) in the flexure structure (16) along a common axis (Y), and is rigidly attached to the inner hub (18). The outer hub (20) which wupports the inner hub (18) and thus the shaft (12), via the flexure structure (16), is attached to an external support structure (28).
