标准范围

ISO 15312:2018定义了油浴润滑滚动轴承的热转速额定值，并定义了确定该参数的计算原则。根据本文件确定的参数适用于给定系列和尺寸的标准设计的滚动轴承，或从摩擦角度来看，与标准设计轴承相关的设计。在标准装配的大多数情况下，允许温度决定了最大工作速度。然后，轴承会产生组件的加热。本文件不包括推力球轴承，因为运动学效应不允许应用本文件中定义的热速度额定值。附录A中的注释1给出了系数f0r和f1r的平均值？f0r用于计算油浴润滑轴承的粘性损失，f1r用于计算轴承的摩擦损失。注2:关于限制标准的解释性说明见附录B。注3:附录C中定义了润滑脂润滑的参考条件。选择参考条件时，应确保润滑脂润滑的热速度额定值与油浴润滑的热速度额定值相同。

ISO 15312:2018 defines the thermal speed rating for oil bath lubricated rolling bearings and defines calculation principles for the determination of this parameter. The parameter determined in accordance with this document applies to rolling bearings of the given series and sizes of standard design or of a design that, from a frictional point of view, can be related to a standard design bearing.In most cases of standard assembly, the permissible temperature determines the maximum operating speed. Heating of the assembly is then generated by the bearing.Thrust ball bearings are excluded from this document as kinematic effects do not allow the thermal speed rating defined in this document to be applied.NOTE 1 In Annex A mean values for the coefficients f0r and f1r are given?f0r for calculating viscous losses of oil bath lubricated bearings and f1r for calculating frictional losses of bearings.NOTE 2 Explanatory notes on the limiting criterion are given in Annex B.NOTE 3 In Annex C the reference conditions for grease lubrication are defined. The reference conditions are chosen such that the thermal speed rating for grease lubrication is identical to that for oil bath lubrication.
