牵引电动机是电力机车和电传动内燃机车传动系统中的主要设备。多年来,我国铁路机车牵引电动机电枢轴承的润滑一直没有专用润滑脂。长期以来我局自行选用3号工业锂基脂,锂基脂是一种用途广泛,使用温度范围较宽的润滑脂,其不足之处是:滴点不够高(一般不超过190℃),氧化安定性、使用轴承寿命等性能不能适应铁路内燃、电力机车牵引电动机轴承润滑的需求,尤其是在铁路运输趋向重载、提速的前提下,运用中暴露出了因油脂变稀流失引起牵引电机轴承烧损、辅助电机损坏等诸多故障,严重影响机车的
Traction motor is the main equipment in the transmission system of electric locomotive and electric drive diesel locomotive. Over the years, China’s railway locomotive traction motor armature bearings lubrication has been no special grease. For a long time our bureau to use its own No. 3 industrial lithium grease, lithium grease is a wide range of uses, the use of a wide temperature range of grease, the downside is: dropping point is not high enough (usually not more than 190 ℃), oxidation Stability, the use of bearing life and other properties can not adapt to the railway internal combustion, electric locomotive traction motor bearing lubrication needs, especially in the rail transport tend to overloaded, speeding under the premise of the use of exposed due to the loss of fat traction caused by traction motor bearings Burning, auxiliary motor damage and many other faults, seriously affecting the locomotive
