摘　　要：为验证4~5 MW风电增速箱轴承性能,研制一台轴承试验机。该试验机可以通过载荷谱控制轴承旋转方向、转速、承受的轴向和径向载荷以及润滑油流量来模拟轴承实际工况,并使用测量轴承振动和温度的方法来侧面反映轴承的实时状态。使用变频器控制变频调速电机使轴承变速变向,液压比例伺服阀可变精准加载,润滑比例流量阀调整润滑油流量,铂热电阻温度传感器测量轴承温度,加速度传感器配合振动采集模块测量轴承振动。试验机可以通过加快轴承转速和增大轴承载荷的方法,只需要普通寿命试验几十分之一的时间就足以完成强化寿命试验。通过50000 min的测试,试验机运行平稳、可靠性良好,数据正常,达到了设计目的。In order to verify the bearing performance of the 4 MW to 5 MW wind power gearbox,a bearing testing machine was developed.The testing machine could control the bearing's rotation direction,speed,axial and radial loads,and lubricating oil flow through the load spectrum to simulate the actual working conditions of the bearing,and the method of measuring the vibration and temperature of the bearing was used to laterally reflect the real-time state of the bearing.The frequency converter was used to control the variable frequency speed regulation motor to change the bearing speed and direction,the hydraulic proportional servo valve was loaded with variable and precise,the lubricating oil flow was adjusted by the lubrication proportional flow valve,the bearing temperature was measured by the platinum thermal resistance temperature sensor,the bearing vibration was measured by the acceleration sensor cooperating with the vibration acquisition module.The testing machine can complete the enhanced life test by speeding up the bearing speed and increasing the bearing load.After 50000 min of testing,the test machine runs smoothly,has good reliability and normal data,which achieves the design purpose.
