本文指出,对于我国高速内燃机车的传动装置,选型的主要目标应为架悬式牵引电动机的牵引传动装置,其中又以ACEA驱动(电枢空心轴结构)更合适;牵引齿轮采用大齿形角并不是提高其承载能力的唯一途径;在牵引齿轮设计中历来采用的大小齿轮均为正变位系数的方式存在着弊端。对于牵引齿轮的润滑剂,建议采用具有良好极压性能的硫磷型工业齿轮油。 This paper points out that for the transmission of high-speed diesel locomotives in our country, the main target of the selection should be the traction drive of the overhead suspension traction motor, of which the ACEA drive (armature hollow shaft structure) is more suitable; the traction gear adopts large gear Angle is not the only way to improve its carrying capacity. There are disadvantages in the way of positive displacement coefficient, which is always used in the design of traction gear. For traction gear lubricants, the proposed extreme pressure performance of phosphorous-type industrial gear oil.
