Mulcher rotor balancing process

Why Rotor Balancing of Mulchers is Necessary Rotor balancing of mulchers is essential not only for reducing vibration and noise during operation but also for preventing premature wear of bearings, reducing the load on the drive, and extending the overall lifespan of the machine. Using a portable balancer allows for onsite balancing without the need to dismantle the mulcher and remove the rotor. Preparation for Balancing Before starting the balancing process, it is necessary to conduct a thorough inspection of the mulcher. It is important to check the bearings for play, inspect the housing for cracks, and ensure that all Read more…

Centrifuge balancing. How to balance the rotor of an industrial washing machine.

This article takes you through our recent visit to a home textile factory where down pillows and blankets are manufactured. Our focus will be on the balancing process of the machinery involved in the production. Pre-Balancing Procedures: Vibrometer Mode Measurements Initial Step Before proceeding with the balancing, it is advisable to conduct measurements using the vibrometer mode. Identifying the Rotor Unbalance If the value of the total vibration is approximately equal to the value of the reverse component, it is likely that the primary cause of the machine’s vibration is an unbalance in the rotor. In this case, you can Read more…

Troubleshooting the balancing process of combine harvesters

Introduction Combine harvesters are vital machinery in agriculture, and like any complex machinery, they require proper maintenance for optimal performance. One often overlooked but crucial aspect of this maintenance is rotor balancing. Balancing rotors on combine harvesters may appear to be a generic task similar to other rotary machines like fans, crushers, and centrifuges. However, every machine has its distinct nuances, and in this article, we delve into the specifics of balancing rotors in combine harvesters. Importance of Rotor Balancing in Combine Harvesters Balancing the rotors in combine harvesters is imperative for several reasons: Reduced wear and tear on bearings Read more…

Introduction to rotor balancing

The rotor is a body which rotates about some axis and is held by its bearing surfaces in the supports. The bearing surfaces of the rotor transmit loads to the supports via rolling or sliding bearings. The bearing surfaces are the surfaces of the trunnions or the surfaces that replace them. In a perfectly balanced rotor, its mass is distributed symmetrically about the axis of rotation, i.e., any element of the rotor can be matched with another element located symmetrically about the axis of rotation. In a balanced rotor, the centrifugal force acting on any rotor element is balanced by Read more…

Balancing the crusher at the Nestlé plant.

Elevated Vibration Levels in Nestle Pet Food Plant In June of last year, a contractor responsible for maintenance at a Nestle plant specializing in pet food production encountered an issue with one of the crushers. Post-maintenance, the machine displayed increased vibration levels, reaching up to 8-9 mm/s, well above the acceptable standards. The Consequences of High Vibration High vibration levels in machinery like crushers can lead to: Increased wear and tear Elevated energy consumption Possible safety hazards Disruption in production quality The Balancing Intervention To address this urgent issue, balancing procedures were performed on the affected crusher. The intervention involved: Read more…

Portable vibrometer balancer ArBalance.

During the balancing of the Fecon forestry mulcher with the FAE attachment, our specialist recorded short videos of the rotor balancing process. In this video, a portable balancing device, the ArBalance vibration analyzer, is used. The balancing process is similar to the process with the Balanset-1A device. The technical characteristics of the device are similar, and vibration sensors and a laser tachometer are suitable for both devices. If desired, the ArBalance can also be used as a measuring system for machines. Its main difference is that the ArBalance is completely autonomous and does not require connection to an external power Read more…

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…

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…
