GAM, a manufacturer of precision gear reducers, couplings, and linear mounting kits, has introduced the EDC Elastomer Drive Shaft Coupling product line. The EDC is the latest addition to GAM’s family of zero backlash drive shaft couplings. Offered in four sizes with torque ratings up to 110Nm, the EDC is available in standard lengths up […]
Servoclass couplings feature fail safe clamping hubs
ServoClass couplings from Zero-Max feature fail safe clamping hubs that provide maximum torque transmission in high speed applications. Without the use of keyways, ServoClass couplings are designed, manufactured and tested to provide shaft engagement in servo motor applications at speeds up to 10,000 rpm. ServoClass design features include precise 304 stainless steel disc members. These […]
The oldham coupling is a form of flexible coupling designed for applications that must be free from backlash. They are also increasingly being used as a replacement for straight jaw couplings. The oldham coupling consists of three discs. Two of the discs, typically made of aluminum or stainless steel, are connected to either side of […]
What do you know about Magnetic Couplings?
Like all other couplings, magnetic couplings are designed to transfer torque from one shaft to another. But what sets magnetic couplings apart, is that they do this without a physical mechanical connection. This makes them suitable for fluid pumping applications since the connection can be made through thin barriers, which help maintain a hermetically sealed […]
Flange couplings deliver higher torque capacity
Ringfeder Power Transmission’s RfN 5571 series of flange couplings, for heavy duty applications, offer easy installation and have higher torque capacity than standard press fits. Equipped with Ringfeder shrink discs, the RfN 5571 flange couplings can be integrated into machines without any heating or cooling, making them easily installable for engineers. They are slip fit […]
What do you know about Gear Couplings?
Though one may not think of gears as being flexible, gear couplings are very much considered to be a flexible coupling. A gear coupling is a mechanical device designed to transmit torque between two shafts that are not collinear. The coupling typically consists of two flexible joints, one fixed to each shaft. These joints are […]
What do you know about Elastomeric Couplings?
Elastomeric couplings are a form of flexible coupling that uses an insert made of an elastomeric polymer to help transmit torque. The design of elastomeric couplings means that the elastic material is meant to wear out before any metal components. This not only saves time and money on maintenance but also means that the couplings […]
The reinvention of the gear coupling
by Michael Jermann, Assistant Editor A new development in gear couplings allows downsizing without loss of performance. Gear couplings handle motion functions that other coupling types are unable to, or that need modifications and de-rating to function. Plus, they can be modified for shear pin service, floating shaft type, vertical applications, electrical isolation, limited end […]
Ringfeder Power Transmission Group adds new line of heavy duty shaft couplings
Ringfeder Power Transmission Group has expanded its offering of heavy-duty couplings with the acquisition of TSCHAN GmbH, a leading supplier of non-shiftable mechanical shaft couplings. TSCHAN couplings are used primarily in heavily-loaded, large-machine applications—including mining, offshore, construction, steel production, cement, pump, compressor and power generation. These heavy-duty couplings complement the precision couplings from Ringfeder’s GERWAH […]
What do you know about Disk Couplings?
A disk coupling is a type of flexible coupling suited for high performance motion control applications and can typically handle speeds of up to 10,000 rpm. The coupling transmits torque from a driving to a driven bolt tangentially on a common bolt circle. This torque is transmitted between the bolts through a series of thin, […]
