Damping elements play an important role in applications that involve moving masses, from wind turbines to vehicles. These devices absorb kinetic energy like an airbag and transform it into deformation energy—protecting your system from damage in the event of a crash or impact.
While there are many different kinds of damping elements to choose from, not all of them strike the right balance between high energy absorption and compact, maintenance-free design. One example that fits the bill is our DEFORM plus® elastomeric shock absorbing units.
Let’s explore how this damping element works:
DEFORM plus units consist of a thick-walled cylinder made of high-quality thermoplastic resin. Upon impact, they fold into a discus-shaped structure—converting motion energy into deformation energy and bringing moving masses to a full stop.
You can mount these units between the moving mass and end stop by bolting them or inserting them between the power flux components.
In addition to having high damping properties up to 95 percent, DEFORM plus units have a compact, versatile design that easily fits tight installation spaces. They come in a variety of sizes and resist corrosion, lubricants and hydrolysis—providing maintenance-free operation.
Types and Applications
Depending on your application, you can choose from two types of DEFORM plus units:
- Type 1—consists of one complete unit made of plastic with the inside guide made of steel. It requires a longer mounting depth than Type 2 because of its longer screw-in thread, which takes in the steel guide upon deformation.
- Type 2—consists of plastic deformation elements and a steel guide and fasteners. Units also feature a steel thrust piece that fastens to the receptacle using an internal screw. Due to this thrust piece, you’ll need more space between the power flux components.
DEFORM plus units are often used in funicular systems—as emergency buffer stops in the stations, for example—or in streetcar bumpers. Other applications include linear gantries, machining centers and rotary tables.
