fuel injector bearing plate assembly and swirler assembly

摘要

A bearing plate assembly for a turbine engine fuel injector includes a bearing plate 30, with an opening 80bordered by a race 82. A swivel ball 90 nests inside the race and is rotatable relative thereto. A lock, which may be a tip bushing 108 resists disengagement of the swivel ball from the race. A fuel injector nozzle 38 extendsthrough an opening 98 in the swivel ball. During engine operation, the ball can swivel inside the race to accommodate rotational movement of the nozzle about lateral and radial axes.
