Overload protection for forestry machines when using pressed wood friction material

Abstract The article proposes an original approach to the protection of forestry machines from overloads when using a friction material made pressed wood. use compressed wood is environmentally important aspect in manufacture materials for safety devices machines. This contributes development green technologies engineering and ensures increase environmental friendliness logging operations. However, point view, self-ignition must be avoided. definition transmitted adjusting torque relation frictional clutch considered. It noted that device slips, will wear out unevenly, form wedge, if working width contacting surfaces large. A diagram calculated presented, as well pressure fuse block, which it can seen how rubber rings are not deformed same way due their difference diameters. operating with frequent overloads, necessary take into account dynamic loads occur during overload at moment triggered.
