  • Distributed load bearing with an inner flex ring
    Patent number: 9746034
    Abstract: A distributed load bearing including a roller, an inner flex ring, a pin and a load distribution spring. The inner flex ring is positioned radially inwards of the roller, and the pin is positioned radially inwards of the inner flex ring, and the load distribution spring is positioned in a cavity defined by the pin and the inner flex ring. The load distribution spring is preloaded, so as to apply a force to the pin and so as to apply a plurality of radially outward forces to the inner flex ring.
    Type: Grant

  • Distributed load bearing with an outer flex ring
    Patent number: 9726225
    Abstract: A distributed load bearing including an outer flex ring, a load distribution spring, and a retainer. The outer flex ring is configured to be positioned radially outwards of a shaft. The load distribution spring is preloaded and positioned radially outwards of the outer flex ring. A radially inner surface of the load distribution spring contacts the outer flex ring. The radially inner surface is an arc defined by a first radius when the load distribution spring is in a lower load distribution mode, and a second radius when the load distribution spring is in a higher load distribution mode. The retainer is positioned radially outwards of the load distribution spring, and the retainer angularly and radially positions the load distribution spring.
