    Pulley drive correction 6 дні(-в) left

    Hi there, we have a pulley driven system consisting of a 45KW motor connected through V belts to a gear reducer. Unfortunately our reducer input shaft (where the 2nd pulley is connected) has broken. The radial forces on the reducer input shaft appear to be too high. Correction of the current pulley system is needed e.g correction of pulley diameters, belt length, etc.
