Definitions

the branches of the bearing member will generally have the form of bands but may also have the form of rods.
the device shown in the drawings comprises, on the one hand, a member 1 forming a bearing, of substantially U-shaped section, the two branches 2 of which diverge from the base 3, and, on the other hand, a pin 4, comprising a head 5 and a rod 6 engaged in an opening 7 in the base 3 of the bearing 1.
the rod 6 of the journal is disposed inside the bearing 1 between the branches 2.
FIG. 1 illustrates the application of the device according to the invention to the maintenance in position of one end of a helical element 13, driven in rotation in a tube 12 of a heat exchanger by the fluid circulating in this tube in the direction indicated by the arrow F1, in order to prevent fouling thereof and / or to ensure its internal cleaning.
the rod 6 of the pin 4 is hollow and the end of the tube 12 is engaged there and crimped or welded.
