introduction
The vibration of a rolling bearing is an important operating characteristic. Vibration will affect the performance of the mechanical system with bearings.
When propagated to the environment in which the operating mechanical system is located, it can cause audible noise, which can lead to system damage and even health problems.
The vibration of a rolling bearing during rotation is a complex physical phenomenon related to the operating conditions. Single set of shafts measured under a set of conditions
The bearing vibration value does not necessarily represent the vibration value under different conditions or when the bearing becomes a part of a larger component. Assessed
The sound generated by the mechanical system of the bearing is more complicated.It is also affected by the interface conditions, the position and orientation of the sensing device, and the sound of the system.
Impact of the learning environment. Air noise-GB/T 24610 (all parts) is defined as any unpleasant, undesired sound.
Because the term "unpleasant, undesired" is subjective, its evaluation is more complicated. It can be considered that the structural vibration of the bearing is
Eventually the driving source for air noise. GB/T 24610 (all parts) only includes vibration measurement of selected bearing structures
method.
This section defines and specifies the physical quantities to be measured and the general test conditions and environment when measuring rolling bearing vibration on a test device.
situation. According to this part, the acceptance party of the bearing can determine the acceptance standard through negotiation to control the vibration of the bearing.
Bearing vibration can be evaluated using any of a number of methods, with different evaluation methods using different types of sensors and test conditions.
No set of values characterizing bearing vibrations can evaluate bearing vibration performance under all possible conditions of use. Eventually, also
It should be based on known bearing types, conditions of use, and vibration testing purposes (e.g.
To choose the most suitable test method. Therefore, the scope of application of bearing vibration standards is not universal. But for the purposes of this section,
Only certain methods with a very broad scope are established as standard methods.
This section specifies the general principles of vibration measurement.The different types of bearing vibration assessment methods with cylindrical holes and cylindrical outer surfaces
Details will be specified in other parts of GB/T 24610.
