Abstract

A metal bellows coupling comprises a first hub, a second hub and a bellows, which is interposed between the first hub and the second hub; the bellows comprises a tubular body having a longitudinal axis and axially delimited by a first end and a second end; the bellows is made of a metal material and has an intermediate portion, which is interposed between the first end and the second end; the intermediate portion of the bellows has a plurality of folds; each end of the bellows has a mating surface, which is configured to come in contact, in use, with a respective hub; the mating surface is at least partially knurled, defining a first knurling.

IPC Classes  ?

• F16D 3/72 - Yielding couplings, i.e. with means permitting movement between the connected parts during the drive with the coupling parts connected by one or more intermediate members with axially-spaced attachments to the coupling parts
• F16D 3/10 - Couplings with means for varying the angular relationship of two coaxial shafts during motion

Abstract

A torque limiter for transmitting motion from a drive shaft to a driven member, and for selectively disconnecting the driven member from the drive shaft when a predetermined transmitted twisting torque value is exceeded. The torque limiter has a hub fitted to the drive shaft; a rotary first flange fixed to an axial end of the hub; a second flange fixed to the driven member; and a number of modules fitted to the first flange. The first flange is fixed to the hub. The modules are equally spaced along the annular portion of the first flange, and one appendage is located between each two adjacent modules.

IPC Classes  ?

• F16D 7/00 - Slip couplings, e.g. slipping on overload, for absorbing shock
• F16D 7/08 - Slip couplings, e.g. slipping on overload, for absorbing shock of the ratchet type with intermediate balls or rollers moving axially between engagement and disengagement
• F16D 43/206 - Internally controlled automatic clutches actuated entirely mechanically controlled by torque, e.g. overload-release clutches, slip-clutches with means by which torque varies the clutching pressure of the ratchet type with intermediate balls or rollers moving axially between engagement and disengagement
