摘要
为了解决圆柱滚子轴承在高DN(轴承内径×轴承转速)值工况下易失效问题,开展了高DN值圆柱滚子轴承的研制工作。结合轴承设计准则,进行300万DN值圆柱滚子轴承结构参数优化设计和材料选取;基于轴承动力学理论,建立了动力学模型并仿真分析,研究了300万DN值圆柱滚子轴承动力学行为;在自主研发的试验机上进行轴承试验,试验过程中监测轴承温升及振动加速度值。结果表明:DN值为300万时,温度低于130℃,振动加速度低于2.0g。通过优化设计,圆柱滚子轴承DN值从200万提升到了300万。
In order to resolve the failures of cylindrical roller bearings under the condition of high DN(bearing inner diameter×inner speed), high DN cylindrical roller bearings were developed. Based on the design criteria of bearings, the structural parameters optimization design and material selection for cylindrical roller bearings to 3 million DN were carried out. Based on the dynamic theory of bearings, the dynamic model of bearings was established and simulated. The dynamic behaviour for cylindrical roller bearing to 3 million DN was investigated;finally, the bearing test was carried out on the self-developed testing machine to verify the rationality of the structural parameters and material selection for cylindrical roller bearing to 3 million DN. During the test, the temperature rose and vibration acceleration of the bearing was monitored. Result showed that when DN was 3 million, the temperature was lower than 130 ℃ and vibration acceleration was lower than 2.0g. Through optimized design, the DN of cylindrical roller bearing has increased from 2 million to 3 million.
