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.

Abstract: A torque limiter for transmitting motion from a drive shaft to a driven member, and for disconnecting the driven member from the drive shaft when a predetermined transmitted twisting torque value is exceeded is provided. 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 facing the first flange; and a number of modules fitted to an annular portion of the first flange, and for transmitting motion from the first flange to the second flange, and for cutting off transmission when the transmitted torque exceeds a predetermined maximum value. The first flange is fixed to the hub at the same annular portion to which the modules are fitted, and the hub has a number of appendages projecting radially outwards and each fixed to the first flange by at least one bolt. The modules are equally spaced along the annular portion of the first flange, and one appendage is located between each. two adjacent modules.
