定向润滑是一种先进的技术，能够降低可倾瓦式轴承的功率损失，改善其性能。与浸没式润滑不同，在浸没式润滑中，轴承部件始终浸没在充油的壳体中，通过定向润滑，部件不会浸没在水中，油从外部直接输送到可倾瓦的工作表面，然后自由下落，从壳体底部排出。在可倾瓦轴承设计中，有几种替代方法可以实现直接润滑的好处。 例如，本文件规定了一种喷嘴式定向润滑系统，其中润滑剂通过安装在可倾瓦推力轴承和轴颈轴承的瓦之间的喷嘴供应给每个瓦。描述了这种润滑的设计概念。

Directed lubrication is an advanced technology that is capable of reducing the power loss and improving the performance of tilting pad type bearings. Unlike flooded lubrication, where the bearing components remain permanently submerged in an oil filled housing, with directed lubrication the components are not submerged and the oil is delivered from an external source directly to the working surfaces of the tilting pads after which it falls freely away to be drained from the bottom of the housing. There are several alternative methods of realising the benefits of directed lubrication in tilting pad bearing designs. As an example, this document specifies a spray nozzle type directed lubrication system where lubricant is supplied to each pad through nozzles mounted between the pads in tilting pad thrust and journal bearings. The design concept of this type of lubrication is described.
