Vibration technology

Vibration technology

Machines in motion generate mechanical vibrations that can have a harmful effect on humans and machinery. Different rubber-metal components ensure vibrations from machines are damped, isolate machine vibrations and prevent excessive noise at the workplace. Werthenbach's premium suppliers such as Freudenberg and Weforma offer numerous products to address this issue.

Barrel-shaped bearings

Barrel-shaped bearings

The outstanding properties of barrel-shaped bearings are their vertical bearing capacity and the capacity of insulation of small amplitude vibrations.

Application

Barrel-shaped bearings may bear masses, which undergo small vibration amplitudes after the respective spring deflection or excite them by themselves. These bearing elements are suitable for selected motors, compressors, aggregates, assembly facilities but also for heavy control cabinets, feedback control installations, fixed control stations, measuring systems.

Cone mounts

Cone mounts

Cone mounts damp vertical vibrations, insulate to protect against structure-borne sound and may absorb big horizontal forces (e. g. brake forces) at the same time.

Application

The cone mount is particularly suited for being used as an elastic connection element for the bearing of motors, aggregates and superstructures, as for the fixed operation as in vehicles and ships.

Double U mounts

Double U mounts

Double U mounts are particularly suitable for insulation works. The outstanding properties of these mounts are a particularly simple structure and the very easy assembly.

Application

Double U mounts are particularly suitable for bearing instruments, aggregates, pumps, condensers and compressors. They are appropriate for the removal of ventilation channels, because they also may compensate structure-borne sound insulation apart from the thermal extension.

Elastomer springs

Elastomer springs

Elastomer springs are suitable for the springing of moved masses as well as for the insulation of vibration exciters.

Manufacturer

Flat bearings

Flat bearings

Flat bearings are bearing elements for the individual use case.

Application

They are used to bear machines, motors or subassemblies in the machinery manufacture or in the vehicle construction.

Hydro bearings

Hydro bearings

As hydraulic damping Elastomer bearings, hydro bearings resolve the conflict to achieve the objective to bear a mass, which is excited by a wide frequency spectrum. Particularly, if here low frequencies – between 5 Hz and 15 Hz- may be used as exciting frequencies, on the one hand a damping in the natural frequency range of the system is wished, but on the other hand a good insulation property in the range exceeding this natural frequency (divergent bearing) is required.

Application

They are suitable for the bearing of internal combustion motors, cabins, pumps and compressors, preponderantly in the agriculture and construction machinery.

Hydro bushes

Hydro bushes

Hydro bushes are Elastomer springs with an integrated hydraulic damping system.

Application

They are suitable to bear internal combustion motors, cabins, pumps and compressors, preponderantly in agriculture and construction machinery.

Instrument bearings

Instrument bearings

These bearings are suitable to protect sensitive instruments and prevent impact load and dynamic excitation.

Application

Instrument bearings are appropriate for vibration insulation of electronic components, measuring instruments and precision mechanical equipment's, instrument panels or electrical panels in the industrial area. It is often required that this bearing protects the instrument or the device from eventual vibrations or impacts, which are initialized via the fixation points. The bearings are suitable for the protection of sensitive instruments from outside impact loads in case of a use of mobile or non mobile instrument bearings.
An other possibility is the insulation to have a protection against structure-borne sound e.g. in small pumps which are fixed to „resonance grounds“ (sheet metals).

Keyed bearings

Keyed bearings

Keyed bearings are preponderantly suitable to bear lightweight, middleweight and heavy engines for the use of mobile and fixed bearings.

Application

Keyed bearings may be used for agriculture and construction machinery. They are suitable to bear generators of ship engines.

Layered springs

Layered springs

The layered spring is an elastic bearing element. It is suitable for the special decoupling of horizontal vibration excitations. These bearing elements are very rigid in the vertical direction at the same time.

Application

Layered springs are appropriate for the bearing of subassemblies, such as motors or gears.

Machine bearings

Machine bearings

The installed flat bearings are protected against mechanical damage and the affecting impact of oil through the special shaping of the machine bearing .

Application

Machine bearings are particularly suited to bear heavy machines, compressors, motors etc.. They enable an essential reduction of the vibrations of the machines and aggregates, which pass into the foundation or the surrounding building.

Metal cushions

Metal cushions

Metal cushions are suitable for the vibration insulation and noise reduction and have elastic properties because of their knit wire meshed shape.

Application

Waste gas systems, electronics, car body, etc.

Manufacturer

M mounts

M mounts

M mounts integrate a good insulation function and the possibility of the levelling of the load in a low overall height.

Application

M mounts are suitable for the anchorage-free installation of heavy aggregates.
They offer the possibility to level the placed machine and achieve the objective of a vibratory insulation.

MO mounts

MO mounts

MO mounts are suited for the use as elastic connection elements .

Application

There is a wide use spectrum of MO mounts, something for bearing of aggregates, secondary aggregates, coolers, small cabins in the vehicle construction but also for the fixation of ventilation channels or exhaust gas lines in the maritime area.

O shaped mounts

O shaped mounts

O shaped mounts have a very non-rigid spring characteristic. This is the reason why they are also called low frequency mounts.

Application

The structure of the O shaped mount permits a good vibration insulation of loads. Typically, they can be found in the instrument manufacture and in the equipment manufacture.

Rails

Rails

Rails are particularly used there where the use of buffers is not possible because of the lack of space or through high load.

Application

Rails are suitable to bear the heaviest machines, installations, aggregates and foundations, e. g. marine engines, big fixed motors, turning lathes, lifting/elevator machines as well as jolters and vibrators.

Round bearings/round buffers

Round bearings/round buffers

Round bearings are widespread constructional elements used to compensate stretch and manufacturing tolerances. They also act as shock absorber.
The outstanding property of buffers is their robustness. The wide range of dimensional variants enable an universal use.

Application

Round bearings and round buffers are used for bearing aggregates, motors, compressors, pumps, test machines etc.
The buffers are particularly appropriate to delimit distances and for springing impacts.

Spherical rubber bearings

Spherical rubber bearings

Spherical rubber bearings are spherical bushes that may absorb axial, radial and torsional movements as well as excursions of the cardanically mobile suspension.

Application

Spherical rubber bearings are ideal vibration-technology based components for joints, which are generally subject to torsion. The bearings are mainly used in bearings, brake levers or pull rods of buses and lorries as well as in torque supports in industrial installations of industrial plants.

Support bearings

Support bearings

Support bearings may be radial, axial and enable angular movements.

Application

Support bearings are particularly appropriate for the connection of a subassembly which is subject to a dynamic loading, such as motors or gears of fixed subassemblies, as e. g. frames.

Ultra bushes

Ultra bushes

Ultra bushes are cylindrical bushes that may absorb axial, radial and torsional movements as well as excursions of the cardanically mobile suspension.

Application

In elastic joints of vibration jolters or elastic bearings as well as in pillow blocks for shafts, axes but also in pull rods and couplings.

V mounts

V mounts

V mounts are optimally suited for many use cases of the vibration and structure-borne sound insulation.

Application

They are appropriate to bear internal combustion motors and electric motors, pumps, compressors and tool machines. V mounts are also used in the maritime area.
