CB Anti vibration mounts

CB Anti vibration mounts

AMC-MECANOCAUCHO® type CB anti vibration mounts are installed in pairs. Installation is simplified as both mounts are fixed with one through bolt and washers at each end of the installed mount.

The CB mount is provided with a built in radial wear plate that prevents the elastomeric element coming into contact with the sharp edges of laser cut holes in support frames or structures that can cause friction in traditionally used semi-bonded mounts . This wear plate reduces the need to machine radius or chamfer holes , reducing cost. The specific design permits high dynamic loading whilst limiting movement due to their multi-axial snubbing.

Technical characteristics

  • The AMC-MECANOCAUCHO® CB mounts are radially more flexible tan axially. This feature is especially interesting for those machines or equipment where radial axis vibration isolation is important.
  • The mount is provided with a built in multi-directional snubbering system that limits the maximum allowed displacements.
  • Different sizes and hardness are available to accommodate applications from 4kg to 800kg per mount.
  • Metal parts are embedded in rubber in order to prevent corrosion.

Applications

- Agricultural or construction equipment cabins, engines, radiators, transmission ,battery boxes.

- Marine equipment

- Mobile Generators or compressors.

- Chassis frames for Military, Bus, Truck, Motorhome and Emergency vehicles.

Operation and Assembly

cb-assembly.jpg

The CB mounts must be installed according to the following installation instructions:

  • They can be installed in frames of different thicknesses according to the values of T, given in the table below. The load vs. Deformation curves will vary depending on the thickness of the frame on which the mount is installed. This thickness "T" determines the degree of precompression of the mount.
  • For the correct installation of the mount, it is recommended to make a hole in the frame with diameter Q, given in the table below.
  • The use of washers is recommended in the event that the support surface does not completely cover the rubber surface.
  • Respect the tightening torque of the mount.
  • In case of any doubt, contact the technical department.

The anti-vibration mounts AMC-MECANOCAUCHO® have a double-bonded design, which makes them suitable to withstand high dynamic forces. The dome-shaped rubber design of this anti-vibration mount allows progressive rigidity in the event of an overload. This fact allows to limit the movement of the suspended element. Symmetric stiffness is achieved using 2 pieces that are vertically opposite. One is installed supporting the load and the other is supporting the rebound forces.
The following graph shows the typical deformation behavior of the part under compressive and tensile loads.
The following picture shows, in a finite element model, how the mount behaves when it is loaded and it makes contact with the snubber.
They are ideal to be used in mobile applications that are exposed to compressive and tensile forces, for example, on-board mounting of equipment on ships, cabins, road transport such as motors, pumps, generator sets.
They can also be used, thanks to their design, to isolate electrical cabinets suspended, both as stabilizers working under compression/tension loads or in shears with a durable and stable rigidity over time.

Advantages

The specific design of the mounts permits high dynamic loads whilst limiting the movement due to the multiple axial snubbing design.
