  • Belt pulley for a belt drive
    Patent number: 4664647
    Abstract: A belt pulley 1 for a belt drive presenting a belt groove 3 having a transition area to the radially outer cylindrical surface 2' which is rounded at a decreasing radius. Previously, this corner was merely chamfered or rounded at a small radius, which in use led to mechanical damage to the belt placed on it. This invention provides a parabola-shaped contour for the transition area, which effectively avoids mechanical damage to the belt, wherein the largest radius RO of the transition curve is located at the later's junction with the groove face 4'.
