Centrifugal coupling, for a hand power tool, has a sliding bearing on the drive shaft, within the coupling drum hub

摘要

The centrifugal coupling (10), especially for a hand power tool, rotates around a drive shaft (11) by a coupling bearing (14) with a coupling drum (12). The coupling bearing is a sliding bearing of a metal, ceramic or sintered material. Or the coupling is of plastics with a low friction and a high wear resistance. The bearing is a hollow cylinder, located within the drum hub (13).
