Pre-assembled and set to the correct torque

Best Practice Story: RINGSPANN supplies complete system units consisting of friction torque limiters and belt pulleys

In Lindner Recyclingtech's stationary waste shredders highly efficient belt and direct drives ensure the powerful rotation of cutting shafts and blade strips. To prevent sudden overloads from getting through to the drive elements, the designers of the Austrian plant manufacturer have been relying on the friction torque limiters in RINGSGPANN’s RSHD series for many years now. Recently, the two companies have intensified their cooperation to such an extent that ready-to-install system units consisting of a friction torque limiter and a V-belt pulley are increasingly being used in the shredder assembly – pre-assembled and already set to the correct torque.Read here about the advantages that result from this in practice.

Safe clamping and easy assembly

Two-part shrink discs from RINGSPANN convince thanks to distance-controlled assembly

RINGSPANN's steel shrink discs are regarded as the premium solution for frictional and backlash-free fastening of hollow shafts and hubs on shafts. In particular, the two-part versions of the RLK 608, RLK 608E and RLK 606 series are very popular in many areas of industrial drive technology. A key reason for this is the safe and simple assembly of these external clamping elements, which does not even require the use of a torque wrench. This benefits mechanical and plant manufacturers and maintenance technicians alike.

A hidden champion of gearing technology

RINGSPANN’s expanding sleeve mandrel is increasing flexibility in fine machining

For all manufacturers of gear cutting machines and users in the field of fine machining who have particularly high demands on the precision and flexibility of their clamping fixtures, RINGSPANN has a real hidden champion in its range: the mechanical expanding sleeve mandrel HDDS. As an alternative to hydraulic expanding fixtures, it convinces with a comparably high concentricity of ≤ 5 µm with a surprisingly great expansion. While the first manufacturers are testing the patented HDDS as a potential standard component in their gear cutting machines, RINGSPANN is also positioning it as a component for simplified entry into automated production.

Lightweight solution for thin-walled die-cast parts

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.

The functional link in hybrid drives

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.
