Reich Drive Systems UK recently announced the addition of a new range of torque limiters to its product range, complementing the company’s range of drive couplings.
Torque limiters provide overload protection to the mechanical drive-train in the event of a sudden increase in torque due to a mechanical failure or other event. The new “RR” torque limiter range immediately disconnects the input side and driven side of the drive-train when an overload occurs, dissipating the inertia within the rotating components.
During normal operation, the torque limiter transmits the torque from the input side to the driven flange through a series of balls, located within indentations on both halves of the unit and retained in position by compression springs. When the torque demand exceeds the pre-set torque value, the balls are pushed out of their indentations. Both sides of the drive-train remain completely disconnected and can rotate independently and freely.
The “RR” range is available in four sizes and with torque settings ranging from 4Nm to 2,600Nm, depending upon spring types and the number of springs specified. They can also be used at temperatures between -200C and + 900C.
