Beschreibung
Zusammenfassung:	A torque limiter comprising: a ramp roller, said ramp roller comprising: an input ramp roller element arranged to be driven by an input torque and having a first ramp surface; an output ramp roller element arranged to drive an output torque shaft and having a second ramp surface; ramp roller balls disposed between the first ramp surface and the second ramp surface; wherein said output ramp roller element is axially and resiliently compressible and wherein an overtorque condition causes axial compression of said output ramp roller element. This arrangement removes all axially sliding friction surfaces from the torque limiter so that the torque bandwidth is reduced, allowing manufacturers to design structures more optimally.
