本文探讨了内燃机车Д100型柴油机轴承中产生干摩擦的原因,这种干摩擦现象会导致轴瓦的擦伤和损坏。根据所进行的研究,提出了提高轴承工作可靠性的措施。最近几年内,开始发现轴瓦擦伤和损伤的现象,这种现象导致轴瓦的损坏,同时还常引起内燃机车柴油机曲轴的报废。这种现象经常在2Д100柴油机上发现,并且更为经带地在负载较大的10Д100柴油机上发现。例如,在1963—1965年内,在奥斯诺瓦、冈达拉克萨、阿克丘平斯克、布古列马、列宁格勒、古主尔 This article explores the causes of dry friction in Diesel engine bearings Diesel engine type Д100. Such dry friction can cause scratches and damage to the bearing pads. According to the research carried out, put forward measures to improve the reliability of the bearing. In recent years, the phenomenon of galling and scratching on the bearing pad has begun to be discovered. This phenomenon leads to the damage of the bearing pad and often causes the discarded diesel engine crankshaft of the diesel locomotive. This phenomenon is often found on 2 Diesel Diesel engines and is more band-pass found on the more loaded 10 Diesel Diesel. For example, in 1963-1965, in Oswyn, Gunndrak, Akchope Pinsk, Bougurema, Leningrad,
