“…To follow the research of Yakout et al [20], we assume in our research the variable damping coefficient in the equation of motion referring it to the variable internal clearance. The variable stiffness in the ball bearing depends in most cases on the contact caused by subjected load or defects on the rolling surfaces [21]. On the other hand, the damping in ball bearings is dependent on operating velocity, lubrication, fitting and material deformation caused by Hertzian deformation on rolling surfaces [22,23].…”

In the present work, a method for the analysis of short time intervals in ball bearings is proposed. We study the effect of the internal clearance on the dynamics of ball bearings using recurrence plots and the recurrence quantification approach. In the proposed method, we focused on the analysis of dynamic states generated from the 2-DOF mathematical model, to which a function changing the damping coefficient in the clearance domain was added. Chosen recurrence methods showed the specific dynamic responses by different values of the radial clearance. The effect of self-consistency concerning the damping effect and vibration development is confirmed. The proposed method can be useful for the prediction of variable radial clearance in time by analysis of the acceleration response of ball bearing during its operation.

“…The first research works based on the use of vibration as a preventive maintenance method for rotating equipment were focused on improving the quality of vibration signal detection systems and their processing to improve the analysis of frequency spectra according to the type of machines (turbines, pumps, fans, gearboxes, compressors) and the type of defects (loads, tensions, misalignment, unbalance, lubrication) [6].…”

The analysis approaches one of the most important requirements of the industrial sector, which seeks to be recognised by the efficiency and performance of its equipment when compared to its coming economic competitors. For data collection and we have followed the ISO 10816 standards, thus using the values of speed in RMS, aiming to reduce the masking of these signals that occurs depending on whether they are high or low frequencies. The study will respond to one of the most important requirements found in the predictive and preventive control of industrial sites. The problem of the predictive systems of maintenance of equipment with bearings lies in the number of monitoring and analysis points that generate a high cost in time and human resources. The aim will be to determine which of all the study frequencies is the most significant and in which position and measurement axis has the biggest impact. To do this, we will analyse the rotation frequency of the blowing machine, the resulting frequency of all the frequencies, the frequency of the impulsion blades and finally the frequency of the bearing. The study would be able to predict when our equipment is going to suffer a failure, reducing the control points and the cost.

“…Many modelling methods were published to study the vibration features of defective ball bearings. For example, Arslan and Aktürk [1], Sassi et al [25], Babu et al [2], Behzad et al [3], Rafsanjani et al [24], Patel et al [23], Liu et al [14][15][16][17][18], Kankar et al [8], and Leturiondo et al [11] proposed kinds of dynamic models of defective ball bearings by considering the defect as the time dependent dis-listed modeling methods. Thus, this paper is focused on developing a multi-dynamic model of a ball bearing with the parallel, offset, and bias local defects.…”

Influence of the local defect dIstrIbutIon on vIbratIon characterIstIcs of ball bearIngs WpłyW rozkładu Wad lokalnych na charakterystykę drgań łożysk kulkoWychLocal defects in ball bearings may occur at the center line of raceway and its surrounding areas. However, most current studies were concentrated in studying the influence of the local defect located at the centerline of raceway on the bearing vibrations, where the effects of local defects surround the centerline were ignored. To overcome this problem, based on Hertzian point contact theory and multi-body dynamic algorithm, a multi-body dynamic model considering the offset and angular distributions for a ball bearing with a local defect on its outer raceway is established. The influences of offset distance and skew angle between the geometric center of local defect and the centerline of outer raceway on the bearing vibrations are investigated. The relationship between the offset distance and the impulse waveform characteristics is obtained, as well as that between the skew angle and the impulse waveform characteristics. The results show that the offset distance and skew angle of the local defect have a great influence on the time-domain impulse waveform characteristics of the bearing accelerations. This paper can provide a useful guidance for the accurate diagnosis of early local fault in the ball bearings.
