1、适用范围 本标准适用于油润滑轴承——首先局限于圆柱滑动轴承——在实验台架上和装车应用中的疲劳试验,并要求承轴是在充分流体动压润滑条件下工作。本标准可应用于动载作用下的单层或多层轴承。 各种工况条件对轴承提出了各种不同的要求,由此而产生了多种形式的轴承试验台架。如果这些试验台架,润滑条件不作详细限定,则由不同的轴承试验台架所得的实验结果就不具有直接可比性,更不能适用于实际应用。不同的试验台架甚至对同样的轴承材料也会产生不同等级的试验结果。
1, the scope of this standard applies to oil-lubricated bearings - first limited to cylindrical plain bearings - in the experimental bench and loading applications fatigue test, and bearing shaft is required to fully hydrodynamic lubrication under the conditions of work. This standard can be applied to single or multi-layer bearings under dynamic load. Various conditions of the conditions of the bearing made a variety of different requirements, resulting in a variety of forms of bearing test bench. If these test bench, lubrication conditions are not limited in detail, the experimental results obtained by different bearing test bench is not directly comparable, but can not be applied to practical applications. Different test benches will produce different grades of test results even for the same bearing material.
