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 […]

Rexnord XTSRLS Thomas disc couplings
Thomas XTSRLS couplings are full-floating shaft couplings designed for applications with relatively long distances between connected equipment, either horizontally or vertically. XTSRLS couplings are a suitable choice when shaft spacing exceeds the maximum length of standard fully machined spacer designs (XTSR52/ XTSR71). Common applications include vertical pumps, fans & blowers, compressors, and paper machines. XTSRLS52: Welded […]
End-to-end coupling solutions for cranes and hoists
When it comes to gearbox coupling applications, some misalignment is unavoidable. This is especially true for cranes and hoists due to their very heavy loads. Fortunately, you can manage misalignment by choosing the right couplings. Here are some of your options specifically for cranes and hoists. Connecting the Gearbox and Cable Drum Recommended for crane-lifting […]
Couplings are the perfect place for sensors: A Design World Trends interview
In a recent conversation with Andrew Lechner of R+W, we discussed IoT functionality in a new line of couplings from the component manufacturer motion components. Here’s what Lechner had to say. Lechner • R+W: 15 or so years ago, we experimented with bellows couplings capable of measuring misalignment. couplings that can provide information about shaft […]
The R+W intelligent coupling
The “intelligent coupling” features direct recording of mechanical data in the drive train, taking accurate measurements through user-friendly operation. Some of the ideas underlying the Industrial Internet of Things (IIoT) include the optimisation of operational efficiency and cost reduction in production and monitoring equipment and machinery. All kinds of production processes can be better adjusted […]
Flexible disc and bellows couplings from R+W
For the past 30 years or more, designers of highly dynamic servo drive systems have been turning to bellows couplings to optimize the stiffness, inertia, and smoothness of rotation in their coupling applications. When it comes to torsionally rigid couplings the stainless steel bellows wins in all three categories. Take for example high-speed camming of […]
Zero-Max CD couplings for high torque flanged gearboxes
Flanged gearboxes are well suited for CD Couplings from Zero-Max. They provide high torsional stiffness in precision applications with fluctuating torque loads caused by aggressive acceleration/deceleration and reversing rotation. A unique flanged hub on the CD Coupling attaches directly to the gearbox output flange. This direct connection and use of the torsionally stiff CD Coupling […]
High-speed couplings from Miki Pulley handle 24,000 RPM with high torque precision
Miki Pulley is introducing its SFM coupling line for direct sale to OEM’s in North America. SFM couplings are designed for high-speed power transmission applications up to 24,000 rpm where high torque and precision alignment is critical. Available in 10 sizes, SFM couplings transmit torque by connecting two shafts while damping system vibrations and accommodating […]
Coupling installation overview from one Ruland engineer
In this column, Bobby Watkins of Ruland Mfg. Co. gives us an overview of some coupling-installation best practices. Updated September 2019 ||Even if a coupling is properly selected, poor installation can cause failures. Following are four installation best practices to keep in mind when assembling your next motion design. 1. Ensure your selected coupling is […]
What are the differences between claw and disc couplings
In addition to gear couplings, claw and disc couplings can be used to connect the drive motor and gearbox in crane and hoist applications. Like the gear coupling, these other two options are designed to compensate for angular, radial and axial shaft misalignment: • Claw coupling—Torsionally flexible, these couplings transmit torque via elastic buffers made […]
