Abstract: A steering gear assembly includes a pinion defining a pinion axis and a rack defining a rack axis. A bearing assembly includes a roller bearing biased against the rack to generate a normal force pressing the rack into engagement with the pinion. The bearing assembly engages an outer surface of the rack at two points circumferentially spanning a large angle to provide improved support. The roller bearing is preferably a plurality of ball bearings engaging an outer race. A deformable member may be utilized that is positioned between the outer race and the rack housing. The deformable member may comprise a series of O-rings which providing a force biasing the outer race towards the pinion.

Abstract translation: 舵机组件包括限定小齿轮轴线的小齿轮和限定齿条轴线的齿条。 轴承组件包括偏压抵靠齿条的滚子轴承，以产生将齿条压紧成小齿轮的法向力。 轴承组件在两个圆周跨过大角度的部分处接合齿条的外表面以提供改进的支撑。 滚子轴承优选为与外圈接合的多个滚珠轴承。 可以使用位于外圈和齿条壳体之间的可变形构件。 可变形构件可以包括一系列O形环，其提供朝向小齿轮偏置外圈的力。
