Abstract
Device for stretching a transmission chain closed in itself and comprising pairs of elongated rocker elements mutually coupled by links, said rocker elements being destined for a torque transferring cooperation with the pulley sheaves of a pulley sheave transmission, and comprising a first and a second supporting surface which support a chain to be treated over an angle of an arc and having an adjustable mutual distance to generate tensile stresses in the chain supported thereby, in which the first supporting surface is freely rotatable accommodated between the first ends of two distant frame parts, the second supporting surface is freely rotatable accommodated on an auxiliary carrier between the two frame parts, said carrier being provided with two opposite stubby shafts, protruding there from and of which the axis lies at a distance from the axis of rotation of the second supporting surface which is rotatably supported by said auxiliary carrier and lies near the second end of the frame parts while of said supporting surfaces at least one can be driven in rotation.
