Worm wheel sets form the core of various drive systems by AUMA Drives. This also applies to slewing gear units positioning the blade of motor graders. These heavy-duty construction machines are also called road graders and are mostly used for levelling unpaved roads. A robust and adjustable metal blade, comparable to a snowplough, levels the surface of the lane. Depending on the soil condition, height and alignment of the blade can be adjusted via a gear unit. As extremely high forces act upon the blade, the overload slip clutch serves as a major safety feature. If a massive obstacle hits the blade, the slip clutch disengages the positive locking to prevent damage to the splines within the gear.
