A wide range of torque limiting couplings, designed to protect all types of machinery from overload, is available from Motor Technology of Stockport.
A wide range of torque limiting couplings, designed to protect all types of machinery from overload, is available from Motor Technology of Stockport.
Machine overload can be caused by a variety of factors such as operator error, electrical or electronic defects and broken or incorrect tooling.
If unprotected, such torque overload would lead to a potentially destructive and dangerous crash.
The SK series of torque limiters, manufactured by R and W, protect machinery and operators by separating the driving and driven components within a matter of milliseconds of an overload occurring.
The range includes four generic designs, all backlash free, to cater for a wide range of applications with torque ratings from 0.1 to 2500Nm.
Each design is available with four variations to cater for different machine operating conditions.
They include: single position re-engagement, where the coupling can be re-engaged precisely 360 degrees from the point of disengagement; multiposition, where the coupling re-engages at the very next position; load holding, where the drive and the driven face are not separated; and freewheeling, where permanent separation occurs in the event of an overload.
Typical applications include: machine tools, NC milling machines, woodworking machines, automated plant, textile machinery, industrial robots, sheet metal processing and printing machinery.
