KTR Engineering Services Manager, Chris Scholz spent a few minutes with Coupling Tips.com to explain idle rotation in torque limiters. “When a torque limiter of this style disengages, its outer casing shifts back, and will not re-engage until manually reengaged; so it basically becomes a free-running bearing. Then, once the engineer determines what the issue […]

What is a frictionally engaged torque limiter?
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 […]
Modular torque limiters for power station furnace conveyors
A global conveyor supplier required torque overload protection on screw conveyors used at a power plant in Indonesia. The conveyors move waste material, provided by local suppliers, to and from the facility’s furnaces. The unmonitored material being transferred often contains large pieces of steel and concrete that can cause jams and possibly damage the conveyor’s […]
Excessive torque and universal joint damage
A major international metals recycler was experiencing problems on their shredders due to universal joint damage caused by excessive torque generated during rotor jams. Repeated repair and replacement of the damaged universal joint cross and bearings resulted in costly downtime. When informed of the problem, Ameridrives Power Transmission application engineers were brought in to develop […]
Torque limiting couplings at Bauma
Voith will be presenting its components for mining and mineral processing at the upcoming construction trade fair bauma 2016 in Munich this year. Voith will exhibit its new Coupling Monitoring System CMS 310, the SlipSet coupling, the Voith TurboBelt Hese Pulley, a TVVS Fluid Coupling and a highly flexible coupling type H in hall C2, […]
Safety coupling basics: What does a ball-detent do?
Couplings are common motion system components used primarily to transmit torque and compensate for misalignment between two shafts. Safety couplings, or overload couplings, are specially designed couplings that slip or disengage in the event that a pre-determined torque limit is reached. The most common type of safety coupling is a low or backlash free spring-tensioned […]
What is a multi-position torque limiter?
By Joyce Laird, contributing editor • Updated August 2018 by Lisa Eitel || Torque limiters are a kind of ball-detent clutch using a series of hardened balls (spring loaded into a detent plate) to clutch the load. Then the balls disengage (release from their detents) once the drive line torque reaches a value sufficient to actuate […]
Couplings see technological and economic growth
Two industry trends could spur change in the application of couplings over the next few years. The first relates to technology improvements for the components themselves. Here, advanced materials are improving couplings in an array of industries. The second is economics-influenced market growth. Expect to see enduring gains in the use of motion designs through […]
