31、rved ISO 15242-4:2017(E)IntroductionVibration in rotating rolling bearings can be of importance as an operating characteristic of such bearings. The vibration can affect the performance of the mechanical system incorporating the bearing and can result in audible noise when the vibration is transmitt
32、ed to the environment in which the mechanical system operates, can lead to damages, and can even create health problems.Vibration of rotating rolling bearings is a complex physical phenomenon dependent on the conditions of operation. Measuring the vibration of an individual bearing under a certain s
33、et of conditions does not necessarily characterize the vibration under a different set of conditions or when the bearing becomes part of a larger assembly. Assessment of the audible sound generated by the mechanical system incorporating the bearing is further complicated by the influence of the inte
34、rface conditions, the location and orientation of the sensing device, and the acoustical environment in which the system operates. Assessment of airborne noise that, for the purpose of ISO 15242 (all parts), can be defined as any disagreeable and undesired sound, is further complicated by the subjec
35、tive nature of the terms disagreeable and undesired. Structure-borne vibration can be considered the driving mechanism that ultimately results in the generation of airborne noise. Only selected methods for the measurement of the structure-borne vibration of rotating rolling bearings are addressed in
36、 the current edition of all parts of ISO 15242.Vibration of rotating rolling bearings can be assessed by a number of means using various types of transducers and measurement conditions. No simple set of values characterizing the vibration of a bearing is adequate for the evaluation of the vibratory
37、performance in all possible applications. Ultimately, a knowledge of the type of bearing, its application and the purpose of the vibration measurement (e.g. as a manufacturing process diagnostic or an assessment of the product quality) is required to select the most suitable method for measuring. Th
38、e field of application for standards on bearing vibration is, therefore, not universal. However, certain methods have established a wide enough level of application to be considered as standard methods.This document serves to define the detailed method for assessing vibration of single-row and doubl
39、e-row radial cylindrical roller bearings with cylindrical bore and outside surface on a measuring device.

45、 100 mm and 900 min1(15 s1) for outside diameters larger than 100 mm up to 200 mm. The tolerance shall be +21% of the nominal rotational frequency.Other rotational frequencies and tolerances may be used by agreement between the manufacturer and the customer; e.g. it may be necessary to use a higher
46、rotational frequency for bearings in the smaller-size range in order to obtain an adequate vibration signal. Conversely, it may be necessary to use a lower rotational frequency for bearings in the larger size range to avoid possible roller and raceway damage.INTERNATIONAL STANDARD ISO 15242-4:2017(E
