When selecting couplings for precise motion applications there are often questions about the most suitable approach for optimizing both performance and economy.

Precision flexible shaft couplings come in two basic forms, both of which are designed to operate without backlash or excessive inertia while compensating for inevitable misalignment offsets between motor/gearbox and load. Torsionally stiff couplings are made with metallic flexible elements and with the intent to eliminate as much twisting deflection as possible so that the rotation of both shafts is kept as well synchronized as can be.
Enhance your fundamental understanding of disc coupling technology through our new whitepaper, outlining how they are constructed, why they are ideal for certain applications, and how they are configured. These designs have been refined for decades for the ultimate in zero maintenance power transmission. Learn how they can work for you!
Precision line shaft couplings are well known for providing smooth stable running over longer distances between shaft ends. Cut to length with fully split clamping hubs for easy drop-in lateral installation, and with reduced hardware requirements, their simplicity can be hard to resist.
Couplings from JW Winco transmit rotary motions and torques from shaft to shaft. They also even out tolerances and mechanical deflection that would otherwise result in damage to drive or measurement configurations.
I have a problem with a disc flexible shaft coupling that is used in screw compressors. This coupling is cracked and damaged after a short time, and the changing rate of this coupling is very high — about every 3 months. But as I understand from the machine manual, the coupling replacement may be every 8,000 hours or 12 months...
When City Scrap & Salvage experienced a catastrophic failure of the driveline between the motor and rotor of its automotive shredder, the company called on Voith Turbo for a
potential manufacturing solution.
Quite often, the collection of precise data in drive technology applications can be problematic. Data monitoring in a rotating drivetrain is difficult
because a direct networking cable connection is often not an available option. Nothing sends shivers down
the spine of for example, a production line manager or a system integrator like uncertainty. That's why achieving
precise measurement of things like torque and other parameters in machinery applications is, while daunting, a
dearly desired goal, especially if those measurements are only available at the drive and motor.
Downtime, downtime, downtime. When it's
planned, it's bearable. When it's not, it's not. To maintain machinery, planned downtime is necessary.
To fix broken equipment, unplanned downtime is excruciating,
especially when your factory is running closer and closer
to full capacity.
