ROBA® DS (ağır yük):

For heavy-duty applications, a special version of the ROBA® DS series was developed, in which the disk pack is connected in a positive locking manner to the hubs, flanges or sleeves via a conical connection. Externally conical bolts are pulled into conical bores in the attachment parts and the collar bushings of the disk packs by tensioning screws. The conical shape produces forces which widen the collar bushings and the attachment parts radially elastically, thus guaranteeing a backlash-free connection of the disk pack. For this backlash-free, positive locking conical connection, far lower screw tightening torques are required in comparison to standard frictionally locking connections. This makes the installation of the ROBA® DS heavy-duty version substantially easier. The disk packs and the sleeves can be installed and de-installed radially without having to move the respective aggregates.
