Especially when application-specific cable solutions must be developed according to customer requirements, the added value of working with such a partner becomes evident.

RINGSPANN offers drive components for all work areas in cement production

Until limestone, clay, sand and iron ore become ready-to-use cement, the raw material mined in quarries undergoes a multi-stage processing and refining process. The drive systems of the machines used here must be tough and extremely resistant to mechanical abrasion. For decades, leading plant manufacturers in the industry have therefore relied on drive technology components from RINGSPANN. The German manufacturer currently supplies high-quality and heavy-duty machine elements for almost all technical work areas in the cement industry.

Wherever multi-stage drive systems with high-speed shafts are to be designed in plant engineering, they can be used as automatically operating and wear-free couplings. The technological prerequisite for the realisation of this innovative high-speed series was the development and commissioning of a unique freewheel test bench at RINGSPANN's main plant in Bad Homburg.

RINGSPANN presents a new range of heavy-duty shaft couplings

In heavy-duty installations in particular even slight radial, axial and angular misalignments in shaft connections can lead to considerable losses of performance and damage to the powertrain. Experience shows, however, that even the use of modern measurement technology to align the shafts is unable to ensure their error-free alignment permanently. This is why the couplings used to connect the shafts have to take over the skew compensation. With its new type GH gear couplings RINGSPANN provides designers with an innovative solution. Designed for high torques and compensation of greater shaft misalignments they are tailored for heavy-duty applications.

With the commissioning of a new test bench just a few days ago, RINGSPANN RCS has considerably expanded the possibilities for further development and quality assurance of its push-pull cable systems. The facility is equipped with a digital control system, two synchronously operating hydraulic cylinders and a mobile terminal. It offers numerous options for different test scenarios and comprehensive evaluations. The German remote control specialist is thus gaining a considerable competitive advantage internationally.

RINGSPANN freewheels regulate the dynamic interaction between the motors

When manufacturers of mobile cranes, construction machinery or heavy transporters develop their engines, RINGSPANN’s freewheels are often involved. These special vehicles are often driven by powerful hybrid systems consisting of diesel and electric motors. The overrunning clutches from the FKh series, for example, are responsible for the division of labour between the two. The reason for this is that without complex control technology, this hydrodynamic clutch solution allows both high differences in speed between the engines to be achieved and different engines of the same drive train to be alternately engaged and disengaged.

RINGSPANN freewheels of the FXM series have been setting the global standard for almost 50 years

RINGSPANN’s FXM-series integrated freewheels have long since become a staple of drive trains in international machine and plant construction. Equipped with the now legendary sprag lift-off type X, they impress with maximum torques of up to 1,230,000 Nm, low lift-off speeds and wear-free continuous operation. The entire FXM series currently comprises more than 40 standard sizes and can now be ordered directly in the company’s online shop. In addition, the price structure has been optimised, which is of particular benefit to small series customers. The freewheel classic is currently arousing the interest of numerous e-mobility manufacturers and is part of the RINGSPANN product range at this year’s Hannover Messe.

RINGSPANN will be focusing on the design of disc couplings at Hannover Messe

RINGSPANN’s product offensive in the field of shaft couplings, which has been ongoing for two years, has led to the inclusion of numerous new coupling types in the supplier’s portfolio. Among designers and developers in industrial drive technology, the group of disc couplings is particularly currently enjoying an increase in demand. The company is taking this as an opportunity to define the correct selection and design of these non-switchable, torsionally stiff shaft couplings as a key issue at this year’s Hannover Messe.
