<p>A modularized belt transmission contained unitarily in its entirety in a single housing (30), in which the center (C) of rotation of a pulley (10), which is mounted on input and/or output rotary shaft (11, 12) and which can be made eccentric with respect to the rotary shaft (11, 12), and the axis (0) of the rotary shaft (11, 22) are maintained in alignment with each other normally, and out of alignment during a belt replacement operation to thereby enable a belt (20) to be replaced with the distance between the input and output shafts (11, 22) kept invariable.</p> |
