摘要： A self-scavenging, hybrid lubrication subsystem for a main transmission gearbox includes a sump fabricated as an integral extension of the lower portion of the gearbox wherein the sump dynamic fluid level is above the gearbox bottom. The interior sidewall of the lower gearbox is modified to include a cylindrical segment having a first radius, a throat segment having a second radius, and a transition segment contiguous with the cylindrical and throat segments. The radial discontinuity between the cylindrical and throat segments defines a nozzle inlet that directs the outflow of lubricating medium in the gearbox bottom to the sump via a nozzle. The outflow end of the nozzle is positioned above the sump dynamic fluid level. Housed within the lower gearbox is a planetary gear train that includes an annular planetary carrier plate having a deflection plate mounted thereto. The periphery of the carrier plate and the cylindrical and throat segments in combination form primary and restricted flow channels. Interaction between the deflection plate and the gearbox bottom exerts a viscous pumping action on the lubricating medium in the gearbox bottom causing it to flow outwardly into the primary and restricted flow channels. Interaction between the periphery of the rotating carrier plate and the structurally-modified sidewall exerts a viscous pumping action on the lubricating medium in the flow channels causing it to flow therethrough. Substantially all of the lubricating medium flowing through the primary flow channel is diverted through the nozzle to the sump.
摘要翻译：用于主变速器齿轮箱的自清洁混合润滑子系统包括作为齿轮箱下部的整体延伸部制造的油底壳，其中油底壳动态流体液面位于齿轮箱底部上方。下齿轮箱的内侧壁被修改成包括具有第一半径的圆柱形部分，具有第二半径的喉部分以及与圆柱形部分和喉部分连续的过渡部分。圆柱段和喉段之间的径向不连续部分限定了喷嘴入口，该喷嘴入口引导齿轮箱底部中的润滑介质通过喷嘴流出到油池。喷嘴的流出端位于集油槽动态液位的上方。在下齿轮箱内装有行星齿轮系，该行星齿轮系包括一个安装有偏转板的环形行星支承板。承载板的周边以及圆柱形和喉部分的组合形成主流和受限流动通道。偏转板和齿轮箱底部之间的相互作用对齿轮箱底部的润滑介质施加粘性泵送作用，使其向外流入初级和受限流动通道。旋转载体板的周边与结构改性侧壁之间的相互作用对流动通道中的润滑介质施加粘性泵送作用，使其流动通过其中。基本上所有流过主流道的润滑介质都通过喷嘴转向油池。
