12V180ZJ型柴油机的主轴承是洛阳轴承厂生产的E942750L型无内圈单列向心滚柱轴承,理论计算寿命折合机车走行公里为50～54万km。本文根据多年来柴油机使用实践所揭示的主轴承磨耗规律,研究了延长主轴承寿命的可行性技术措施,并论证这些措施在提高柴油机可靠性、降低柴油机修理成本方面能够取得较大的经济效益。
12V180ZJ diesel engine main bearing is produced in Luoyang Bearing Factory E942750L-type single row non-spherical roller bearings, the theoretical life expectancy equivalent to locomotive running km to 50 to 54 million km. Based on the rule of main bearing wear revealed by the diesel engine usage practice for many years, this paper studies the feasibility of extending the main bearing life and proves that these measures can achieve greater economic benefits in improving the reliability of diesel engine and reducing the repair cost of diesel engine.
