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 […]
Oldham Coupling
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 […]
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 […]
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, […]
What do you know about Beam Couplings?
Most couplings can be categorized as one of two types, rigid and flexible. Rigid couplings are used in applications where proper alignment is essential, while flexible couplings, such as beam couplings, are suited for applications where there is some acceptable misalignment. A beam coupling, sometimes called a helical coupling, consists of a single piece of […]
Non-Metallic expansion/deflection coupling improves safety while reducing installation time
The non-metallic expansion/deflection coupling from T&B Fittings improves safety and reduces installation time for joining rigid polyvinylchloride (PVC) conduit that is subject to movement in any direction at structural joints. Its design makes the coupling up to five times faster to install, while its versatility enables a five-to-one reduction in stock keeping units (SKUs). The coupling […]
Step-Flex couplings reduce resonance in stepper motor ball screw assemblies
Mechanical resonance in motion systems can cause, not only unpleasant noise, but can lead to oscillations in the machine that reduce the positional accuracy of the system. This oscillation can also cause the system to take too long to find its correct positioning and further degrade performance. In rare cases where extreme oscillation is present, […]
Altra Industrial Motion aquires Guardian Industries
Altra Industrial Motion Corp., a global manufacturer and marketer of electromechanical power transmission and motion control products, announced the acquisition of Guardian Industries, Inc. The acquisition of Guardian is expected to be accretive to earnings in the range of $0.01 to $0.02 per share, excluding any one-time or acquisition related costs, during the 2014 fiscal […]
Zero-Max CD Couplings add Electrical Insulation Protection to Mechanical Components
Motion system designers have a new option to arrest electrical current. In addition to their primary function, Zero-Max CD couplings are designed with composite flex elements that are non-conductive. The flex element designed into the couplings provides electrical insulation while protecting mechanical components from system overloads. CD Couplings do not pass electrical current through the […]
