TORQUE LIMITER

摘要

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.

1. A torque limiter for transmitting motion between a rotary drive shaft (2) and a driven member (3), and for disconnecting said driven member (3) from said drive shaft (2) when a predetermined transmitted twisting torque value is exceeded; the torque limiter comprising:
a hub (4) fitted to said drive shaft (2); a rotary first flange (6) fixed to an axial end of said hub (4) facing said driven member (3); a second flange (12) fixed to said driven member (3) and facing said first flange (6); and a number of modules (14) fitted to an annular portion of said first flange (6), and for transmitting motion from said first. flange (6) to said second flange (12), and for cutting off said transmission when the transmitted torque exceeds a predetermined maximum value; said first flange (6) being fixed to said hub (4) at said annular portion to which said modules (14) are fitted; said hub (4) having a number of appendages (5) Projecting radially outwards and each fixed to said first flange (6) by at least one bolt (7); the torque limiter being characterized in that said modules are equally spaced along said annular portion of said first flange (6), and in that one said appendage (5) is located between each two adjacent said modules (14).
