Propeller blade assembly.

摘要

A propeller blade assembly which enables the mounting of a propeller blade (1) in a hub assembly (2) includes a bearing arrangement that circumferentially surrounds and engages with a section of the propeller blade. The bearing arrangement comprises an inner race assembly (3) of angular contact bearings, and an outer race assembly (5) of roller bearings. The roller bearings being arranged so that the axis of rotation thereof is substantially parallel to the longitudinal axis of the propeller blade (1). A propeller blade assembly in accordance with the present invention is more suited that conventional designs to withstand high torsional and centrifugal loading whilst still providing a reasonably compact unit.
