68 laminated elastomeric bearings with bevelled upper plates – on the piers

The contents should enable them to design laminated elastomeric bearings with a view to using them on bridges, viaducts and similar structures.

2.1 – General principles of composition A laminated elastomeric bearing is a "block of vulcanized elastomer (…) reinforced internally by one or several steel plates, chemically glued (bonded) during vulcanization. (…).

Concerning this matter, the publication of the standard NF EN 1337 (after the French standards) regarding product specifications and CE marking for laminated elastomeric bearings are giving rise to improvement. • Installation defects.

Located in an earthquake risk zone, the bridge is fitted with 56 pot bearings and 12 banded elastomeric bearings, designed and produced to withstand major earthquakes and adapt to large variations in temperature (approximately 60°C).

Type 2 Hoop wrapped container with a seamless metallic liner

The second shrink fit (9) allows greater torques to be transmitted from the gear (4) to the shaft (2) than the first shrink fit (8).

A shrink fit tool holder that without decreasing of the strength of the tool holder, can realize a large fastening allowance by shrink fitting.

The field can include a first elastomeric element that includes a first elastomeric material and a second elastomeric element different than the first elastomeric element that includes a second elastomeric material.

The shrink-fit tool holder (10) has a chuck (40) where the shank (2) of the tool (1) is fixed by shrink fit.

A shrink fit tool holder that without decreasing of the strength of the tool holder, can realize a large fastening allowance by shrink fitting.

The elastomeric ring is made from elastomeric material.
