Type FHHS freewheels are among the latest new developments from RINGSPANN. They are suitable for applications with high speeds of up to 12,000 rpm and are designed for the implementation of overtaking functions in stationary multi-motor drives and turbines. In systems with redundant drive systems in which high-speed shafts operate, they can therefore be used as wear-free and automatically switching couplings. The technological basis for the implementation of this freewheel innovation was the commissioning of a test bench at RINGSPANN's main plant, which is the only one of its kind in the world.

RINGSPANN offers cone clamping elements for applications with bending moments

In its one-stop shop, RINGSPANN provides mechanical and plant engineering designers with a large selection of different shaft-hub connections for power transmission in drive trains.

RINGSPANN clamping fixtures enable precision machining across several process stages

Whenever rotationally symmetrical die-cast components with thin walls have to be machined in the production of modern automotive transmissions, the demands on the clamping technology increase considerably. This is because the clamping systems used for this purpose must exhibit a high degree of concentricity, must not deform the workpiece under any circumstances and should ensure optimum chip removal. RINGSPANN has therefore developed a clamping trio specifically for external and internal machining as well as for the balancing and crack detection of sensitive aluminium gear pots, which has quickly established itself as a semi-standard in large series production.

RINGSPANN is expanding the brake caliper range for its industrial disc brakes

RINGSPANN is driving forward the expansion of its industrial brake portfolio with a great deal of creativity and a laser focus on the requirements of its customers in the mechanical and plant engineering industry. One of the most recent measures in this context is the addition of three particularly large brake calipers for the realisation of high-performance disc brakes in emergency stop and extreme applications. Among others, this stands to benefit manufacturers of drive systems for heavy-duty and mining technology, as well as power plant construction and offshore technology.

RINGSPANN RCS is commissioning an innovative duplex test bench for push-pull cables

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.
