Torsion damper for tensioning device has torsion spring creating axial force between friction pair, casing and annular flange, acting on friction element

摘要

The torsion damper is for a tensioning device (1) for belts or chains which has a casing (2) and a tensioning arm (6), with a torsion spring (8) between them. The clamping arm is supported against the casing by an annular flange (9) fixed to the tensioning arm. The torsion damper (10a) is fitted in the annular flange
