Torque limiting couplings at Bauma

Voith will be presenting its components for mining and mineral processing at the upcoming construction trade fair bauma 2016 in Munich this year. Voith will exhibit its new Coupling Monitoring System CMS 310, the SlipSet coupling, the Voith TurboBelt Hese Pulley, a TVVS Fluid Coupling and a highly flexible coupling type H in hall C2, booth 239.

The Slip Set and a CMS 310 Modul

SafeSet torque limiting couplings prevent machine damage in high value rotating equipment, such as steel mills, tunnel drilling machines, crushers and many more. Working like a mechanical fuse in the driveline, it protects the system from costly breakdowns.

SlipSet is based on the same technology as the SafeSet coupling, but with the ability to instantly slip instead of release in the event of a torque overload. The SlipSet units are very compact and can be installed in areas with a minimum of space, to ensure the most optimal position in a drive line.

The new CMS 310 is the latest generation of Voith Coupling Monitoring Systems. It is built on a PLC based platform, which makes supervision and monitoring of torque limiting couplings possible in addition to release detection as well as slip detection. The control unit continuously calculates and sends signals into a monitored supervision system indicating the current slip angle. The status information can be used to immediately identify any need for action; as a stand-alone solution or integrated in already existing monitoring systems.

Other benefits of the CMS 310 include that it upgradable and scalable; it is based on industry standard components and can easily be integrated in existing systems via the Profibus connection.

TVVS Fluid Coupling

TVVS Turbokupplung

The showcased Controlled-Fill Fluid Coupling model, type TVVS, is predominantly used in belt conveyor drives. These types of couplings are used to ensure smooth start-up, protect the drive against overload and dampen torsional vibration, thus preventing unplanned downtimes and increasing the lifetime of drives.

The Voith fluid couplings require minimum maintenance, are well suited for use in extreme environments and completely insensitive to harsh conditions like dust, dirt and humidity. Voith further offers fluid couplings with water as operating medium (type TWVVS) especially for potentially explosive atmospheres or couplings with outer casing made of spheroidal cast iron (type TUVVS) for use in operations with relevant material requirements.

Voith is also engineering partner for customer-specific drive solutions in new-build and modernization projects.

Highly flexible coupling type H

Hochelastische Kupplung Typ H

The highly flexible coupling type H is a torsional vibration damper especially well-suited for construction vehicles with torque converter gear units. It features two damping systems working in parallel: a spring-mass system and a hydraulic damping system. The coupling protects the driveline against torque shocks and increases the lifetime of all connected components. Operators benefit from a higher productivity and profitability of their vehicles.

The highly flexible coupling type H is a modern torsional vibration damper which reacts multi-functionally to complex vibration scenarios. It automatically recognizes the difference between the need for vibration damping and the need for vibration isolation during driving. To do this the coupling utilizes the hydraulic operating principle. The coupling is designed to be temperature resistant, space saving and maintenance free.
