摘要： 以浮环轴承为研究对象,计入浮环径向温度梯度,建立了浮环轴承分布温度模型和内膜-浮环-外膜热量传递模型。研究了浮环径向温度梯度对浮环轴承润滑性能的影响规律。结果表明:浮环轴承径向温度梯度对浮环轴承的润滑性能有显著影响,计入浮环径向温度梯度时,浮环轴承内膜温度增加,总摩擦功耗和总端泄流量略有减小;与浮环轴承内层间隙为0.02 mm时相比,内层间隙为0.04 mm时,内膜温度和总摩擦功耗分别减少了16.0%和15.9%;总摩擦功耗随内圆半径的增大而增加,适当减小浮环轴承的内圆宽度可以改善浮环轴承的润滑性能。

Abstract: The temperature model and heat transfer model among inner-film-floating-ring-outer -film of floating ring bearing were established, in which the temperature gradient of the floating ring was taken into consideration. The effect of the temperature gradient on the lubrication performance of the floating ring bearing was discussed. Results show that, taking the radial temperature gradient of the floating ring into consideration, the inner-film temperature increases, the overall frictional power loss and end discharging capacity slightly decrease. With outer eccentricity ratio of 0.4, when the inner film clearance increases from 0.02mm to 0.04 mm, the inner film temperature and total power loss are decreased by 16.0% and 15.9%, respectively. The total power loss increases with the inner circle radius. The lubrication performance of the floating ring bearing can be improved remarkably by appropriately decreasing the inner circle width.

Key words: mechanical parts, mechanical design, radial temperature gradient, heat transfer, structural parameters, inner film temperature, lubrication
