Ringspann presents the new clamping coupling for fixing driven rotary swivel tables in multi-axis machining centers. Immediately after its premiere last fall, this mechanical-hydraulic high-precision solution has become the favorite of numerous well-known manufacturers of machine tools and turn-pivot portals.
With its exceptional angular accuracy and holding torques of up to 2400 Nm as well as a very high torsional stiffness, it clearly exceeds the performance of conventional clamping systems.
High-quality clamping disks transfer the axial force of helical compression springs into a radially acting force, thereby tapering a specially designed, annular deformation body. This purely mechanical action ensures an absolutely torsion-resistant all-round clamping of the axle journal of the positioning axis. The clamping is quickly released again by applying the clamping coupling with 115 bar hydraulic pressure. As a result, the positioning of the rotary swivel table is immediately free again for the process in the next angular position.
Background: Rotary tilting tables and gantries are used in the coordinate field of modern machine tools and machining centers to position the A and C axes. Their kinematic task is to support the accurate and fast approach of the workpiece in any required angular position. In the latest-generation turn-tilt tables, this is achieved by positioning axes that are driven by directly and precisely controllable torque motors. After taking their defined angular positions, they are firmly clamped and have to hold their position absolutely securely during the ongoing processing - that is, under load.
The market offers a number of different clamping systems for this task. However, increasing demands of the users on the achievable accuracies and the transmittable torques make both the manufacturers of rotary swivel tables and the machine tool builders increasingly looking for ever more powerful clamping systems for their positioning axes. The new clamping coupling for clamping rotary swivel tables should soon replace many well-known clamping systems products.

Hannover Messe Hall 5, Stand D32 / 1 Expert knowledge At the moment, the multi-plate clutch is enjoying increasing demand from designers and developers of industrial drive technology against the background of the Ringspann product offensive, which has been running for two years. In the field of shaft couplings, this has led to the addition of numerous new types of couplings to the portfolio. This addresses the correct selection and design of the non-switchable, torsionally rigid shaft couplings at the Hannover Messe 2020.
Hannover Messe Hall 5, Stand E04 Intelligent machine elements provide important measurement data for transparency in the drive train. This is how they support efficient and predictive machine maintenance. At the Hannover Messe 2020, Mayr Antriebstechnik presents intelligent solutions for brake monitoring as well as new approaches for networked clutches. The drive specialist invites visitors to think along the new paths.
KBK Antriebstechnik has developed the KBGK and KBGK-T articulated couplings that connect shafts and components with extremely little play and even compensate for high radial and angular misalignments. They are made from high-quality materials such as aluminum and steel, are torsionally rigid in the circumferential direction and give in to radial forces and angular deviations.
The ball screw or trapezoidal screw is usually not connected to the drive journal of a motor or gearbox in a rigid manner, but via a flexible coupling. This can compensate for misalignments or misalignments and minimize vibrations and shocks in the drive train. Dr. Tretter now offers compact shaft couplings for this.
SPS Hall 3, Booth 419 Rigid couplings of the "Torqmax step bore" series from Orbit Antriebstechnik enable the play-free connection of shafts with different diameters thanks to their graduated bores. For a low mass moment of inertia, the couplings are made of aluminum, additionally anodized to prevent corrosion, and some are also available in stainless steel.
EMO Hall 5, Stand D89 The "Simple-Flex" series from Jakob Antriebstechnik is a new type of spacer coupling that can be manufactured up to a length of 6 m and does not require additional intermediate storage. A sophisticated composite tube with a multi-layer, angle-specific fiber configuration enables a particularly simple design that does not require any coupling compensation elements at the tube ends.
EMO Hall 3, Stand E22 Ringspann presents the new clamping coupling for fixing driven rotary swivel tables in multi-axis machining centers. Immediately after its first presentation last autumn, this mechanical-hydraulic high-precision solution has become the favorite of numerous well-known manufacturers of machine tools and swivel-swivel portals.
With its clutches and brakes, EMO Hall 8, Stand E45 Mayr Antriebstechnik offers complete solutions from a single source for the reliable protection of machine tools and machining centers. For example, a wide range of backlash-free, powerful servo couplings ensures a secure connection between the shafts. And a wide portfolio of reliable safety brakes is available to protect gravity-loaded axles.
Flender completes its "N-Arpex" coupling, which was introduced in 2017, and introduces two further expansion stages with eight and ten screw points. As a result, the coupling series covers a diameter of up to 988 mm and a torque of up to 2.000.000 Nm. Due to the compact design and an increased bore capacity, a size increase is also possible.
