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。

Abstract

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.
