摘要

#CMT# #/CMT# The damper for a seal subject to vibration, e.g. at a concrete mixer, has a rubber buffer (20) between two metal plates (21) fitted with mounting studs (22). At least one metal inert (23) is centrally within the buffer, of a lightweight and thermally conductive material. The insert is in thermal conductive contact with at least one metal plate. The insert can be cooled. #CMT#USE : #/CMT# The damper is for a seal which is subjected to heavy vibration, e.g. at a concrete mixer. #CMT#ADVANTAGE : #/CMT# The structure prevents heating of the rubber buffer from the concrete mixer before starting to producer concrete. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic section through the damper. 20 : rubber buffer 21 : metal plates 22 : mounting studs 23 : insert #CMT#METALLURGY : #/CMT# The insert is of aluminum foam.
