Foreword
GB/T 24610 "Measurement method for rolling bearing vibration" is divided into 4 parts.
--- Part 1. Basics;
--- Part 2. Radial ball bearings with cylindrical holes and cylindrical outer surfaces;
--- Part 3. Spherical roller bearings and tapered roller bearings with cylindrical bore and cylindrical outer surface;
--- Part 4. Cylindrical roller bearings with cylindrical bore and cylindrical outer surface.
This part is the third part of GB/T 24610.

This section replaces GB/T 24610.3-2009 "Method for measuring vibration of rolling bearings-Part 3. With cylindrical holes and cylindrical appearance
Compared with GB/T 24610.3-2009, the main technical changes are as follows.
--- Modified the lower cut-off frequency of the low frequency band with a rotation frequency of 900min-1 (see Table 2, Table 2 of the.2009 edition);
--- Added "Example of frequency range of non-set rotation frequency" table (see Table 3);
--- Change "peak measurement" to "measurement of pulses and sharp pulses" (see 5.3, 5.3 of the.2009 edition);
--- Modified the illustration of the sensor setting position and the schematic diagram of the double-row tapered roller bearing (see Figure 2, Figure 2 of the.2009 edition);
--- Deleted the "requirements for operators" (see 6.4 of the.2009 version).

introduction
The vibration of a rolling bearing is an important operating characteristic. Vibration can affect the performance of a mechanical system with bearings. When vibration
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" has a subjective nature, 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.
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. However, some methods have established
It has established a very wide scope of application and is considered a standard method.
