Overview
粗壮，坚固且稳定
Lufkin Gears Integral Gearbox经过定制设计，以满足不断增长的行业需求和需求。每个客户都得到我们的全面工程支持，以确保满足所有协作需求，以便即使是最复杂的设计也可以顺利进行，并且最好的产品也可以交付。这些单元足够强大，可以处理重型叶轮外壳的负载，但要保持避免振动问题所需的技巧。可以设计它们以通过API 617与API613和ATEX满足。
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.
齿轮套管
定制每个齿轮套管以满足涡轮设备的安装和装载要求，其中包括专用的有限元分析（FEA）以优化体系结构。套管盖可以设计为拆卸，而无需卸下叶轮外壳。如果卸下盖子，则可以在内部限制轴承，以将齿轮元件固定在适当的位置。齿轮套管是用重钢板制成的，以确保耐磨度和刚度，以确保长寿和稳定性。如果需要，可以在套管上以轴驱动或偏移安装的方式提供油泵安装溶液。
轴承
Multiple bearing design options are available to suit the application. Multiple styles of sleeve bearings, taper-land thrust, tilt-pad journal, tilt-pad thrust, and integral squeeze-film damper bearings can be used to meet a variety of design considerations.
Stability
我们的整体齿轮单元的设计考虑到稳定性。我们定制每个小齿轮，以安全地远离临界速度，与客户合作以建立叶轮和密封重量/惯性要求，并交叉耦合数据以确保无故障的操作。我们可以根据API 613和617的要求提供未阻尼，阻尼和稳定性分析。
状态监测
内华达州弯曲or similar equipment is available on all shafts to monitor radial and axial vibration as well as phase angle. Magnetic speed pickups can also be mounted to sense the gear teeth, or mounted to sense a gear with a specific tooth count. We use embedded simplex and duplex RTDs or thermocouples for bearing temperature monitoring.
