现代球轴承和滚子轴承具有很低的摩擦系数,很适宜于重载和高速条件下的应用。在正常工作状态下,滚动轴承的温升通常很小,无需特别注意。但是,在诸如高负荷、高速度、高温环境、热加工流体或轧辊,蜗轮、表面密封或轴承预加负荷等应用中估计会产生很大 Modern ball bearings and roller bearings have a low coefficient of friction and are suitable for heavy-duty and high-speed applications. Under normal working conditions, the temperature rise of rolling bearings is usually small, without special attention. However, applications such as high-load, high-speed, high-temperature environments, hot working fluids or rolls, worm gears, surface seals, or bearing preloading can be expected to produce large
