Abstract
A self-lubricating bearing suitable for marine applications, such as supporting hatch covers, has a bearing surface defined by a flexible woven pad. This woven pad is draped over a pillow plate and captured in position. To ensure that there will be a low friction interface between the pillow plate and the load supported on the bearing if the woven pad is severely damaged or lost, the pillow plate is designed to present a surface having a coefficient of friction lower than a metal-to-metal interface to the load.
Claims20
A bearing assembly comprising:
- base means for supporting a bearing element, said base means being adapted to be secured to a support element;
- plate means for defining a bearing surface area, said plate means being positioned in registration with said base means;
- flexible, self-lubricating bearing means disposed over said plate means, said bearing means being a woven member comprised of at least a first fiber, said woven member conforming generally to the form of said plate means and extending beyond the edges thereof;
- capture means for retaining said woven member on said plate means;
- means for maintaining the registration of said plate means with said base means;
- and
- means for reducing the coefficient of friction of the surface of said plate means which faces said woven member, said coefficient of friction reducing means being integral with said plate means.
