About the experience of balancing the cardan shaft directly on the motor grader.

Found an old correspondence between our lead specialist and one of our customers.Correspondence from ten years ago! Autor : Valery Davydovich Introduction I must admit that I was very surprised and pleased with the results of the letter written to us by Andrey Kobyakov, the driver of the motor grader. His letter even surprised me – a specialist with more than 35 years of experience in the field of vibrodiagnostics and balancing. And for a long time I worked in the defense industry and balanced more than 1500 different machines and mechanisms starting from ordinary fans and smoke pumps and Read more…

Using Balanset-1A as a measurement and computing system in balancing machines. Video inside

Extent of Usage in Stationary Measurement Systems Statistics on the consumption structure of balancing devices manufactured by Vibromera reveal that approximately 30% of these devices are purchased for stationary measurement and computational systems in balancing machines or stands. Softbearing Machine Design Essentials The design illustration indicates a mobile frame affixed to stationary stands using ribbon springs. Influenced by the centrifugal force generated by the rotor’s imbalance, the trolley can undergo horizontal oscillations relative to the stationary stand. These oscillations are measured with a vibration sensor. Using Balanset-1A as a measurement and computing system in balancing machines Key Features of Softbearing Read more…

Improving the Quality of Micro Fans Through Precision Balancing

Introduction Micro fans, commonly known as coolers, are an integral part of various electronic systems, including personal computers and medical devices. One of the critical metrics for evaluating their quality is the level of vibration and noise they generate. This article discusses an experiment aimed at reducing the vibration levels in a batch of 100 coolers, specifically designed for medical equipment. The Importance of Low Vibration and Noise Vibration and noise can significantly affect the efficiency and longevity of electronic devices. In medical equipment, these factors become even more critical, as even a small deviation can have serious implications. Therefore, Read more…

Cost-Effectiveness of Balanset Devices: Revolutionizing Rotor Balancing and Vibration Reduction

The balancing of rotors is a central issue in numerous industries, particularly those that manufacture and operate fans. While the need for precision and reliability is paramount, cost-effectiveness is also a significant consideration. The Balanset series of devices has emerged as a disruptive force in this context, offering a unique value proposition. This article elucidates the cost-effectiveness of the Balanset series in rotor balancing and vibration reduction, as of early 2023. Balanset Series: A Compelling Value Proposition The Balanset series, comprising the Balanset-1, Balanset-1A, and Balanset-4 devices, has carved a unique niche in the market primarily due to its exceptional Read more…

Measurement of relative rotor vibration using non-contact linear displacement sensors.

With the Balanset-1A you can measure the relative vibration of the rotor using non-contact linear encoders. 1.1 Selection of the sensor type and setting. Depending on the task, either vibration sensors or displacement sensors can be used for measurements. To select the type of sensor it is necessary on the panel “Sensor type” (at the bottom of the main window) to put a mark in the field “Vibro” or “Linear”. Before starting the measurement it is necessary to make sure that the conversion coefficients of the sensors are set correctly. For this purpose press the button “F4-Settings” in the main Read more…

Application of the Fourier transform to the analysis of vibration signals.

Andrei Shelkovenko. One of the developers and founder of Vibromera. The translation of the article may contain inaccuracies. Fourier transform and signal spectrum In many cases the task of obtaining (calculating) the spectrum of a signal is as follows. There is an ADC, which with sampling frequency Fd transforms continuous signal, which comes to its input during time T, into digital samples – N pieces. Then this array of samples is fed to some program (for example FourierScope) which outputs N/2 some numeric values. To check if the program works correctly, we form an array of samples as a sum Read more…

Simple but effective balancing stands

In a number of cases, for balancing of various rotors, relatively simple stands are created, which allow to provide qualitative balancing of rotor mechanisms of various purposes with minimal costs. Below there are several such stands made on the basis of a flat plate (or frame) mounted on the cylindrical compression springs. These springs are usually selected so that the frequency of natural vibrations of the plate with the balanced mechanism installed on it was 2 – 3 times lower than the rotor frequency of this mechanism during balancing. Figure 1. shows a photograph of a balancing stand for abrasive Read more…
