introduction：Generally speaking，FAGbearing[FAGbearing:The main shaft bearing is made of a solid inner ring、Outer ring、The ball、And a single row angular contact ball bearing consisting of a cage assembly with a solid window cage。]The rolling bearing itself does not produce noise。Commonly felt“Bearing noise”In fact, the cylindrical roller bearing directly or indirectly produces a vibration sound effect with the surrounding structure。 This is why many times the noise problem can be viewed as a vibration problem involving the entire plain bearing application。Excitation caused by changes in the number of rolling elements under load when a radial load is applied to a certainFAGbearing[FAGbearing:Principal axis

introduction： Measuring the heating degree of gear reducer is used“Temperature rise”Instead of using“temperature”，when“Temperature rise”Suddenly increases or exceeds the maximum operating temperature，It indicates that the gear reducer is faulty。below，General will take you to understand the factors affecting the temperature rise and the temperature limits of each part of the gear reducer。 For the normal operation of the gear reducer，In theory, the temperature rise under the rated load should be independent of the ambient temperature，But in fact, it is still affected by factors such as ambient temperature。 (1)
