Anti-screwing corrector device, for a turning device for boiler construction.

摘要

The invention concerns a turning device 3 for hoops for boiler 1 construction. The jack 21 actuates a crank arm 20 in order to define at each instant the angular position of the shaft 11 upon which the roller 8 rotates. The shaft 11 is carried by an eccentric in the bearings of the fixed cheek plate 9. Application : elimination of the "screwing" phenomenon of the hoop 1 along its geometric axis 4, by slaving the instantaneous angular position of the shaft 11.
