Apart from transmitting the rotor torque, locking assemblies installed in crushers are subjected to further loads such as bending moments and radial impacts. The factors which have to be considered for these applications are briefly described in this article. Please also watch the video and learn how modern impact crushers work. Function principle Impact crushers […]

RINGFEDER announces GWE 5113 servo-insert coupling with new hub design
RINGFEDER has recently released its GWE 5113 series of elastomer jaw servo-couplings, featuring a new hub design. This design eliminates radial loads and achieves uniform power transmission with an even clamp force and symmetrical arrangement of clamp and screw positions. GWE 5113 couplings precisely transmit torques from 3 to 560 Nm. The hub is slit […]
What’s reducing the service life of your metal bellows coupling?
It is generally assumed – and typical applications confirm – that metal bellows couplings reliably work over the entire service life of an installation if the coupling is correctly designed. In the future, this can no longer be taken for granted as applications are becoming more and more dynamic. Such applications require you to consider […]
Customizing torsionally rigid disc couplings with shrink disc for wind turbines
Couplings play a critical role in energy equipment — especially wind turbines. These durable components, which connect the gearbox to the generator, ensure the rotor blade system is operating as it should. Without the right coupling, a wind turbine can’t function properly, driving up maintenance costs and downtime. These scenarios are not welcome—especially since any […]
Heavy-duty shaft coupling strategies
Move beyond traditional coupling designs to improve performance and cut costs Heavy-duty shaft couplings have traditionally had a couple of defining design characteristics. For one, these couplings usually rely on keyed shaft connections. For another, they tend to be over-engineered with regard to stiffness. In many ways, this design approach makes perfect sense. Keyed connections have […]
Locking assemblies: beyond the basics
Although numerous methods exist for coupling two components, choosing the best option for the intended application requires an understanding of all available technologies. For example, when clamping a hub onto a shaft or axle, splined or keyway-based couplings are a popular choice. Another traditional method of connecting gears to shafts involves shrink fitting, which uses temperature differences […]
Ringfeder complete coupling systems for heavy-duty cranes and hoists
In a new video from Ringfeder, the company explores the types of couplings that excel in crane and hoist applications. Ideal for heavy-duty equipment, barrel couplings are highly robust and torsionally stiff. They also compensate for misalignment and are easy to assemble. The Ringfeder offering includes bore sizes up to 550 millimeters and torques up […]
Ringfeder elastomer jaw couplings
The rotationally resilient couplings of the RINGFEDER series GWE, TNM, TNS, and TNB are puncture-proof and flexible in all directions and therefore compensate for angular, parallel, and axial shaft misalignments of the connected machines. Misalignments can be caused for example by inaccurate assembly, heat movements, or settling phenomena. Avoiding torsional vibration By virtue of the […]
