Tensioning device of a tensioning roller for transmission by the flexible link, operating by elastic deformation of a solid deformable parallelepipedal.

摘要

Tensioning device pressing elastically a tensioning roller (7) on a flexible link (1) of transmission, by elastic deformability of a deformable parallelepiped solid constituted by a pair of elements made of composite flexible strips (14) held in parallel, spaced apart by means of their ends, gripping a block carries - bearing (12) and an adjustable fastening (11), possibly carrying a means to modify the flexibility of the elastic tensioning device (8), which optionally comprises a means for damping the vibrations of the flexible link (1).
