Almost everyone is familiar with vibration dampers made of elastomers. When conditions get tougher, rubber-based vibration isolators reach their limits. Production in a multi-phase process, partly by hand The basis or the main element of every vibration damper is the damping pad made of stainless-steel wire. This is produced in a multi-stage process. First and foremost is the knitting of several stainless-steel wires into a stocking. This stocking is then rolled to create a mat. While these processes are automated, the next step is manual. The existing mat is pulled over a mandrel and brought into its mostly cylindrical shape. At the end of production, this blank is pressed and spot-welded to create an elastic molded part. This is used as a damping pad. Design parameters An element is characterized by the same values that describe the corresponding geometric shape. For the cylindrical cushion, the outer diameter, inner diameter and height are required as a basis. For a rectangular cushioning element, the width, length and height. Other shapes can be adapted based on the geometry. The volume or density can be deduced…

Vibration decoupling machine mountings at Eurotier and Energy Decentral. The trade fair season 2022 is slowly coming to an end and will once again offer a highlight with the trade fair duo Eurotier and Energy Decentral in the coming week. RG+ Schwingungstechnik will be represented in Hanover with its range of stainless-steel vibration dampers. At Energy Decentral, the exhibition for decentralized energy supply, the focus is primarily on the storage of exhaust gas aftertreatment components, as well as complete CHP modules. Silencers, heat exchangers or catalytic converters are supported by means of compression-tension elements with integrated damping pads. For CHP modules, spring isolators are a very good option for decoupling. At Eurotier, it is mainly air classifiers, screens, mixers or even tank systems that can be successfully decoupled with special machine feet. What unites all applications is the successful extension of service life of the stored components, which is achieved using decoupling elements. We are pleased to advise…

RG+ Schwingungstechnik GmbH offers a wealth of expertise in vibration-decoupling machine and component mountings. This year again at the Solids in Dortmund. Niche product for specific applications Many users will not think of knitted wire mesh when they think of machine feet and vibration dampers. The often cylindrically shaped pressed parts, which are more reminiscent of a kitchen sponge or pot cleaner, are known as a niche product to a rather small circle of users. ”Everyone who gets to know the product finds it exciting at first glance. However, vibration dampers are not what people spend a lot of time on. That’s where the standard is taken. The question is whether it makes sense to use a knitted wire mesh for the corresponding application,” says Markus Günther, development engineer at RG+. The areas of application are not as limited as you might think. Heat exchangers, catalytic converters or silencers are applications that are often decoupled using stainless steel vibration dampers. Pumps, mixers or crushers also fall into this area of application. This is where the circle closes to the trade fairs for granulate,…

Vibrations induced by applications are disturbing, annoying and from a certain point on lead to disruptions in production - this should be avoided Wherever something moves, vibrations occur. These are generally disturbing for the environment and in the worst case can lead to machine failures and thus to restrictions in production. Active machine mounts from RG+ Schwingungstechnik GmbH offer the possibility of isolating vibrations and thus preventing expensive production downtimes and disruptions to the environment. In addition to our dampers made of a stainless steel wire mesh, the product portfolio of RG+ Schwingungstechnik GmbH also includes spring isolators consisting of a combination of springs and damping pads. This solution offers the customer, in addition to the pure vibration isolation by springs, a damping integrated into the bearing. Unintentional rocking of the machines in the resonance range can be effectively reduced. However, this damping is not the only advantage of the FR series. When additional dynamic loads are considered, the cushion has a positive effect on the action of the spring isolators,…

Vibration dampers made of metal offer many advantages - their durability, freedom from maintenance, resistance to non-pH neutral substances as well as high temperatures. Our main-product, the damping cushion made of stainless steel is knitted and pressed in a special process. Depending on size, density and design it can be loaded in a range between 5 and 20.000 kg. It can be pressed e.g. in conical or rectangular shape. Versions with bunches and steps are available, also. Standard materials are 1.4301 and 1.4404. Additional materials and special designs are on demand. RG+ offers the following damping cushions as standard elements: * GKK as a vibration damper in conical form * GKR as a vibration damper in rectangular form * GKB as a vibration damper with a bunch
