ABSTRACT:
A flexible bearing for a rocket motor is constructed by forming a relatively very thin coating (about 0.01 inches thick) of an elastomer such as natural rubber on one surface at least of an equally thin continuous reinforcement strip of pliable fabric, and wrapping the coated fabric strip about an axis of rotation with a multiplicity of turns to form a laminated component comprising a continuous helical coil having aligned edges defining the transverse width thereof and having spaced top and bottom surfaces, the function of the reinforcement strip being containment of the elastomer, whereby a laminated helical coil, and hence, flexible bearing, with a given amount of elastomer contained therein for shearing, is produced with a substantially reduced dimension between the bearing top and bottom surfaces.
