KTR Engineering Services Manager, Chris Scholz took a moment to speak with Coupling Tips.com about the make-up of frictionally engaged torque limiters. “A frictionally engaged torque limiter is one of the more basic styles of torque limiter, one of the oldest styles. It uses a couple of friction disks that compress a plate, a sprocket, or […]

How does a ball detent torque limiter work?
Coupling Tips.com asked KTR Engineering Services Manager, Chris Scholz about the basics of ball detent torque limiters. “In a ball detent design, there is some type of spring mechanism, or a spring disk, a curved spring disk, or a spring with a flat plate. A precision hole is also machined in that disk, or plate, […]
What are torque limiters used for?
Coupling Tips.com asked KTR Engineering Services Manager, Chris Scholz about the basics of what a torque limiter is used for. “It’s a device that allows limiting of torque for high-shock, catastrophic failure type applications. They’re used when people don’t want to damage their equipment. Engineer’s will integrate a torque limiter to be set at a […]

New test bench for large couplings
KTR has launched a new test bench for large couplings covering a performance range of up to 500,000 Nm at its headquarters in Rheine, Germany. The test bench allows the calculation of mechanical coupling parameters and performce service life testing. The testing sample of the initial series is a torque limiter intended to be used […]
Motion systems application examples: Couplings
By Mike Santora Couplings are simple yet precisely engineered devices that connect shafts to transmit torque and compensate for misalignments. But many variations of coupling designs exist to complement machine dynamics and meet specific application criteria. Couplings are either torsionally rigid or flexible. Flexible couplings compensate for misalignments, while rigid designs handle drive components already […]
A Novel Way To Use Jaw Couplings In Extreme Temperatures
The German couplings specialist, KTR, has come up with a novel way to use jaw couplings in temperatures too high for the elastomer materials conventionally used for coupling spiders. It has developed a spider made from “knitted” steel wire, similar to the steel wool used to clean pots and pans. Standard spiders are made from […]
TOOLFLEX Metal Bellow-Type Coupling
Compact coupling design is required more frequently by customers in order to realize high performance with a narrow mounting space. In order to meet these requirements, KTR’s backlash-free ROTEX GS jaw-type coupling has already been added to their product range as a compact design. Now the range of the torsionally stiff TOOLFLEX metal bellow-type coupling […]
