Many researches were conducted in the past in order to maximise the efficiency of gearboxes, and for many of the sources of power loss, very effective models and tools are already available and can significantly help to optimise the design. Nevertheless, for the load‐independent power losses of gears only in the recent years some progress has been made. Concerning these losses, numerical simulations can help the designers in optimising the internal shape of the casing, thus ensuring the proper lubrication of all the components and reducing the undesired splashing losses.

静压对变速箱功率耗散的影响

为了使齿轮箱的效率最大化，过去进行了许多研究，并且对于许多功率损耗源，非常有效的模型和工具已经可用，并且可以极大地帮助优化设计。然而，仅在最近几年，由于齿轮的与负载无关的功率损耗，才取得了一些进展。关于这些损失，数值模拟可以帮助设计人员优化外壳的内部形状，从而确保所有组件的正确润滑并减少不希望的飞溅损失。
