Extremely low backlash joint couplings for servo and linear motors
KBK Drive Technology has it universal joints KBGK and KBGK-T developed that connect shafts and components with extremely little play and even compensate for high radial and angular misalignments. They are made of high-quality materials such as aluminum and steel, are torsionally rigid in the circumferential direction and give in to radial forces and angular deviations.
Both couplings can be easily and quickly connected to the drive train: With the KBGK this is done by the combination of internal thread / external thread, with the KBGK-T by side clamping screws. The coupling is available with outer diameters from 18 to 100 mm. Depending on the size, the KBGK can absorb axial forces between 200 and 13.000 N. Not only can linear motors be connected to it, but also shafts can be connected with very little play. Here the KBGK can compensate for radial misalignments of up to 2,5 mm and angular misalignments of up to 6 °.
Connection via servo motors
With the KBGK-T, servomotors are connected to the drive train quickly and with little play. The articulated coupling is suitable for use in packaging, printing and assembly machines as well as in handling and positioning systems. The KBGK-T can precisely transmit torques between 2 and 580 Nm and reliably compensates even large angular and radial misalignments. Sizes with shaft diameters from 3 to 55 mm are available
Thanks to special bushings and guides, both couplings are durable, very rigid and almost free of play. Due to their high level of compensation, both articulated couplings are also suitable for applications in which the expected shaft misalignment cannot be precisely estimated in advance.
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.
