An integrated geared centrifugal compressor system is described that includes an eccentric bushing that accommodates bearings and seals to maintain rotor concentricity for various pinions integrated in a fixed gearbox design to provide multiple impeller speeds through a single gearbox design. In one aspect, a system includes, but is not limited to: a pinion configured to be rotatable about an axis of rotation by a bull gear; a rotor coupled to the pinion gear; and an eccentric bushing configured to receive a bearing assembly through which the rotor extends to support rotation of the rotor, the eccentric bushing having an outer side surface and an inner side surface, where the inner side surface is eccentric with respect to the outer side surface to align the axis of rotation with a central axis of the bearing assembly. 描述了集成齿轮传动离心式压缩机系统，其包括容纳轴承和密封件以针对集成在固定齿轮箱设计中的各种小齿轮来保持转子同心度的偏心衬套，以通过单个齿轮箱设计来提供多个叶轮速度。在一个方面中，系统包括但不限于：小齿轮，该小齿轮被构造成能够由大齿轮使其围绕旋转轴线旋转；转子，该转子联接到小齿轮上；以及偏心衬套，该偏心衬套被构造成能够容纳转子延伸穿过的轴承组件，以支撑转子的旋转，偏心衬套具有外侧表面
