Integral Gears

粗壮,坚固和稳定

Lufkin齿轮整体齿轮箱是定制的,以满足不断增长的行业需求和要求。每个客户都获得完整的工程支持,以确保满足所有协作需求,以便即使是最复杂的设计也是平稳的,并且可以提供最佳的产品。这些单元足以处理重型叶轮壳体的装载,但维护避免振动问题所需的精细性。如果需要,它们可以设计成通过API 617和ATEX符合API613。

Gear teeth and thrust collar

Gear teeth are typically preferred to be single-helical for better axial end play control, but can be double-helical when suitable. For single helical teeth, we will utilize either integral or shrunk-on thrust collar(s) to eliminate the need for a redundant thrust bearing on the high-speed pinions—greatly improving unit efficiency. Teeth are precision ground and can be modified to correct torsional and bending contact mismatches. Gear teeth and thrust collar(s) can be case-hardened, nitrided, or through-hardened as needed.

Gear casing

Each gear casing is custom-designed to meet turbo equipment mounting and loading requirements which include a dedicated finite element analysis (FEA) to optimize the architecture. The casing cover can be designed to be dismantled without removing the impeller casing. Bearings can be internally constrained to secure the gear elements in place if the cover is removed. The gear casing is fabricated out of heavy steel plate for robustness and stiffness to ensure long life and stability. Oil-pump mounting solutions are available as shaft-driven or offset-mounted on the casing if needed.

Bearings

可以使用多种轴承设计选项来适合应用程序。多种款式的套筒轴承,锥形陆推力,倾斜垫,倾斜焊盘推力和整体挤压膜阻尼器轴承可用于满足各种设计考虑因素。

整体齿轮轴承

稳定

我们的一体式齿轮单元设计牢记稳定性。我们自定义每个小齿轮以安全地从临界速度运行,与客户合作,建立叶轮和密封重量/惯性要求和叶轮交叉耦合数据,以确保无故障运行。我们可以根据API 613和617所需提供稳定的,阻尼和稳定性分析。

状态监测

所有轴上都有Bentent Nevada或类似的设备,以监测径向和轴向振动以及相位角。磁速拾取器也可以安装以感测齿轮齿,或安装以感测具有特定齿数的齿轮。我们使用嵌入式单面和双工RTD或热电偶进行轴承温度监控。
