Certain bearings, such as elastomeric bearings, use alternating layers of metal shims and layers of elastomeric material. During fabrication of the bearing, considerable effort is made to install the layers elastomeric material so that each layer is in precompression. In some bearings, a lower grade of elastomeric material so that the ...

1. Introduction. Reinforced elastomeric bearings are composites composed of alternating horizontal layers of elastomer and reinforcement. Elastomeric bearings must be designed to support the applied vertical loads from the overlaying bridge or other structure while allowing for large lateral displacements to occur due to thermal movement, creep, seismic, and other load sources.

The bearing assembly (101) includes one or more elastomeric members (107a - 107d) loaded in a precompression by a shim (105a - 105c) that includes a shape memory alloy. The shape memory alloy is configured to generate the precompression in the elastomeric members (107a - 107d) upon a temperature change.

Further, elastomeric bearings can be significantly less costly than pot or disk bearings. Therefore, elastomeric bearings are of interest for use in higher-demand applications that include larger reactions and more significant thermal movements. However, there is uncertainty in the behavior of the elastomeric bearings in these applications.

Toward that end, the use of elastomeric bearings in main rotor systems is increasing. These polymer bearings have the ability to deform and return to their original shape. As such, they can absorb vibration that would normally be transferred by steel bearings. They also do not require regular lubrication, which reduces maintenance.
