For exact dimensioning torque limiters latest simulation and calculation programmes are available. Therefore let us know many data of your drive. The more precise these data are, the more precise are the results of calculation. Make use of this possibility and discuss with us the application in advance.
Please notice: High masses at the drive or driven end can mean long slow-down times also in case of torque limiters entered in function. This can cause increased wear at the coupling. Therefore in case of high speeds we recommend to use a free-rotating (load-separating) safety clutch (KTR-SI idle rotation coupling). If required, please contact KTR’s engineering department.
Besides it is important fo the failure-free operation to define the engaging torque definitely above the max. operating torque of the unit. Therefore we recommend to set the coupling at least 30% above the max. operating torque.
For all torque limiters an electrical disconnection of the drive should be provided. Long slipping or locking times can destroy the coupling. We kindly assist you when selecting sensors, end switches or speed controls.
A smooth operation is only guaranteed if the overload torque set exceeds the maximum operating torque of the machine (see diagram below).
