Abstract
A lightweight damper pulley is provided which can be produced in a simple manner. The damper pulley includes a central portion, including a cylindrical boss portion to be fixed onto a rotary shaft, a main portion extending radially outwardly from the larger diameter part of the cylindrical boss portion and a central flange bent to extend horizontally from an outer periphery of the main portion. This forms a substantially U-shaped cross-sectional profile. The pulley also includes a belt retaining portion made of metal plate that also has a substantially U-shaped cross section profile. This space is determined between an outer belt supporting wall, an inner belt portion flange and a radially extending connecting wall. The pulley is constructed by reversing the two U-shaped profiles or dissecting the belt retaining flange to the interior of the central flange, with an elastic, damping ring forcefit therebetween. The belt retaining flange can also be moved radially outwardly to compress the elastic.
