  • Method of making continuous reinforcement for flexible bearing laminate
    Patent number: 4927481
    Abstract: A method for simplifying the fabrication of flexible bearings and reducing the production costs thereof includes preparing reinforcement material for the laminate in the form of a continuous helical arrangement, placing a first end ring in the bottom of a mold with a laminate engaging surface facing upwards, placing the continuous helical arrangement of reinforcement material on the laminate engaging surface of the first end ring, with layers of elastomeric material alternating with layers of reinforcement material, to form a laminate, placing a second end ring in the mold with a laminate engaging surface thereof in engagement with the laminate, coaxially therewith and with the first end ring, and debulking and curing the assembly.
    Type: Grant
    Filed: February 3, 1989
    Date of Patent: May 22, 1990
