根据内燃机车现行技术保养制度规定,架修时首先要检查各轴承的技术状态。在进行TO—2、TO—3级检查和小定修时,要通过轴箱部件的外观检查来确定轴箱轴承是否能继续使用。在大定修时要检查轴承的技术状态和润滑脂的状态。当发现轴承有明显故障或润滑油中含有水份或磨料杂物时,则要对轴箱部件作进一步的检查。在这种情况下,润滑脂的质量可用手指研搓来鉴别。当含有少量的混合物时,这种方法的效果就差一些;当含有大量的金属杂质
According to the provisions of the current technical maintenance of diesel locomotive regulations, the first frame to repair the technical status of the bearings. When carrying out TO-2, TO-3 inspections and minor repairs, check the appearance of the axlebox components to determine if the axlebox bearings will continue to be used. In the fixed repair to check the technical status of the bearing and grease status. When there is a clear bearing failure or lubricating oil contains water or abrasive debris, then the axle box components for further inspection. In this case, the quality of the grease can be identified by finger rubbing. This method is less effective when it contains a small amount of a mixture; when it contains a large amount of metal impurities
