Upgrading an old balancing machine with hard-bering supports. Using the Balanset as a measuring system.

Modernization of an old balancing machine with hard-bearing supports.

Earlier in the article, I described the modernization of an old balancing machine with soft-bearing supports. For such machines, we install the Balanset-1A balancing device in the case of machines with two supports, and the Balanset-4 in the case of machines with more supports. In this article, we will consider the modernization of an old balancing machine with hard-bearing supports. Their supports are made in the form of rigid plates with shaped grooves (slots). The natural vibration frequencies of these supports are significantly (at least 2-3 times) higher than the maximum rotational speed of the rotor being balanced on the Read more…

Balancing stand with soft support.

The image shows a simple balancing stand being used to balance gears. The main feature of softbearing support balancing stands is that they have relatively compliant supports based on spring suspensions, spring-mounted carriages, flat or cylindrical spring supports, and so on. The natural frequency of oscillation of these supports is at least 2-3 times lower than the rotation frequency of the balanced rotor that is mounted on them. As shown in Figure, the movable frame (slider) 2 is attached to the fixed support posts 1 of the stand using a suspension system with ribbon springs 3. Under the influence Read more…

Portable balancer, vibration analyzer, and balancer machine Balanset-1A.

Over the course of more than 5 years, approximately thousand devices of the Balanset series have been produced. During this time, three versions of the device have been released, and a lot of work has been done to improve both the device itself and its software. We strive for continuous improvement! We respond to the requests of our customers by adding new features. Throughout the entire existence of our company, we have continued to adhere to our pricing policy and strive to keep prices as low as possible, constantly expanding the capabilities of our devices and improving their quality.

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…

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

Balancing Coolers for Medical Equipment Balancing a Batch of 100 Coolers In response to a request from a medical equipment manufacturer, we undertook the task of balancing a batch of 100 coolers. Our process demonstrated high precision and effectiveness, significantly reducing vibration levels. Building a Stand for Cooler Balancing To accomplish this task, we constructed a stand consisting of a lightweight platform suspended on steel strings. This minimized external influences and provided precise and stable conditions for balancing. Using Epoxy Compound for Balancing We used a fast-curing epoxy compound as the corrective mass, applying it to the microfan blades. The Read more…

Balancing the rotors of electric motors.

Balancing Electric Motor Rotors: Methodologies and Outcomes Introduction The functionality and longevity of electric motors are profoundly influenced by the balance of their rotors. Especially after repair interventions, these rotors may exhibit imbalances that can reduce the efficiency and lifespan of the motors. Enterprises that specialize in motor repair often encounter this challenge. This article aims to elucidate the methodology of using specialized balancing equipment and the consequent outcomes, ensuring effective motor performance. The Necessity of Balancing Equipment Rotor imbalances can lead to an array of problems, including increased wear, reduced efficiency, and even equipment failure in severe cases. Hence, 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…
