Creating the perfect hollow shaft connection in gearbox applications isn’t easy. You need to maintain strict dimensional tolerances between the solid and hollow shafts—a process that requires precise, yet costly machining. Ringfeder’s Smart-Lock set overcomes these challenges. It provides a firm, yet flexible connection with clearances up to 0.2 mm. Thanks to its user-friendly, economical […]
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 […]
What are gear couplings and how do they work?
Gear couplings are designed to transmit torque between two shafts that are not collinear. They typically consist of two flexible joints—one fixed to each shaft—which are connected by a spindle, or third shaft. The gear coupling connects the drive motor to the gearbox in hoist mechanisms, but it can also connect the gearbox directly to […]
Couplings in heavy-duty crane and hoist applications
Cranes and hoists are only as good as the components that make them up. One of their key components is the coupling, which is essential to maintaining uptime and enhancing the safety and reliability of your operation. Without the right coupling, your crane or hoist may not function properly, causing your manufacturing process to grind […]
A big “twist” on Ringfeder’s standard shrink disc
Given the range of applications for shrink discs, Ringfeder has always offered a wide range of sizes. But sometimes, engineers may need a larger model than they carry. In these cases, Ringfeder will customize one of its standard shrink discs to fit a customer’s needs—which is exactly what they did for an industrial gearbox company […]
How sweet it is: Coupling assists in sugarcane processing application
By Matheus Mendes The sugarcane industry is one of the most flourishing segments of the Brazilian Economy. With a production of up to 624 million metric tonnes of sugarcane in the 2017 harvest season, the country holds the world record production for both sugar and ethanol from this raw material. Uniting technology in both agricultural […]
What are the main functions of a coupling?
Couplings transmit torque in drive systems. But they are able to do more. These are the three essential functions of a coupling. Transmitting torque Power and speed result in torque. Only with the transmission of torque a machine can be operated. Compensating misalignment “If a coupling is not installed in the ideal physically straight […]
Change at Logistics at Ringfeder Power Transmission
Changing market demands and the resulting requirements which have to be met by our company constantly bring forth new challenges and modifications. For this reason, RINGFEDER POWER TRANSMISSION has implemented a new logistics concept. Our logistics operations in Groß-Umstadt are going to be relocated to our production sites in Neunkirchen and Dobrany (Czech Republic). These […]
Ringfeder adds gear couplings to Rapid Response Program
The Ringfeder Rapid Response Program has let you enjoy next-day shipping on our shrink disc locking devices, metal bellows couplings and servo couplings. Now, we’re once again expanding this popular program to include gear couplings. Our Gear Couplings transmit torque via hubs with crowned gear teeth, which are in permanent mesh with the straight gear […]
Ringfeder talks couplings for aeroderivative gas turbines
By Ringfeder Power Transmission Gas turbines are available in many different designs and the power output of the individual models varies considerably – from 200 kW to more than 400 MW. The performance of gas turbines for industrial applications typically ranges from 5 to 40 MW. Dependent on the power, the speeds vary from 3,000 […]
