标准摘要
[中文适用范围]： 本文件定义了油浴润滑滚动轴承的热速度额定值，并确定了该参数的计算原则。按照本文件确定的参数适用于给定系列和尺寸的标准设计滚动轴承，或从摩擦角度来看，可以关联到标准设计轴承的设计。 在大多数标准装配情况下，允许温度决定了最大工作速度。装配的加热由轴承产生。 推力球轴承不包括在本文件中，因为运动效应不允许应用本文件中定义的热速度额定值。 [外文原描述]： 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.
