Pressure regulators

Pressure regulators introduced to trains ED05 series pressure regulators from Aventics combine control electronics, pressure sensor, and direct drive via a proportional solenoid in a single closed unit. The ED05 pressure regulators were originally developed for use in commercial vehicles. In addition, they have been reliably applied in mobile work machines. In trains, the pressure regulators from Aventics reliably control brake cylinders for comfortable braking or are used as air spring control valves for adjusting the access height to any station platform. With sturdy components made of die-cast aluminum and steel, the ED05 series complies with the fire protection and shock and vibration resistance requirements of the railway industry. Their operating temperature ranges from -40 to + 70 °C. The ED valves process pressure regulation tasks in a decentralized manner without additional parameter adjustment based on the set points of the superordinate train control. They dynamically and precisely control the movement and force without additional control settings. Integrated pneumatic return lines automatically compensate disturbance variables. The intelligent actuators communicate with the superordinate train control either directly via an analog interface or via a bus module. www.aventics.com Flexible torque arm for an optimum assembly of torque motors www.ktr.com KTR developed a torque arm for torque motors the use of which may increase the service life of the motor bearings by up to 50 %. RADEX-N FNZ compensates for axial and radial misalignment, transmits torques up to 12,000 Nm and can be used up to a temperature of 250 °C. It ensures a torsionally rigid connection of the motor while compensating for axial and radial motions resulting from misalignment, manufacturing inaccuracies or thermal expansion. It allows for reducing the load on the bearing while increasing the service life of the motor bearings. At the same time the special structure of the torque arm ensures a highly torsionally rigid torque transmission. As a result the torque motors connected are able to transmit the full performance regarding dynamics and control accuracy to the machine axis. By using the RADEX-N FNZ the user generates a detachable screw connection with the torque motor whereby necessary maintenance work such as replacement of bearing or gaskets is easy to perform. The shaft connection, e. g. clamping elements, can be assembled via the assembly window in the spacer when the torque arm is installed. The RADEX-N FNZ is fully made of steel. The future of automation: the modular X90 control Synchronous reluctance motors combined with high-performance converters PRODUCT NEWS B&R continues to open up new possibilities in mobile automation with its X90 product line for mas-tering mobile control and I/O tasks. The comprehensive set of standardized components is perfect for imple-menting flexible automation concepts. The heart of the X90 system is a controller with a powerful ARM processor and 48 multifunction I/O chan-nels. Basic features include interfaces for CAN, USB, Ethernet and the real-time POWERLINK bus system. The extremely robust cast aluminum housing provides space for up to four expansion cards. These can add additional I/O channels, interfaces and even a full-fledged safety controller with safe I/O. Additional expan-sion cards for WLAN, Bluetooth and GPS interfaces are in planning. All products in the X90 family are designed for use in harsh industrial environments. They can handle operat-ing temperatures from -40 to 85 °C as well as strong vibrations or shocks in addition to being resistant to salt, UV light and oil. www.br-automation.com/en The new firmware version 4.8 allows Sinamics S120 high-performance low-voltage converters to be combined with Simotics synchronous reluctance motors. This connection is suited for drive solutions in which the dynamic response of induction motors is no longer sufficient but the high performance of permanently excited synchronous motors would be excessive. Typical applications include winders, extruders or servo pumps. Control has also been optimized in terms of efficiency for generator operation, opening up additional scope for other regenerative applications. The modular system comprising Sinamics S120 lowvoltage converters and Simotics synchronous reluctance motors enables customized high-performance machine concepts to be implemented with the utmost speed and flexibility in industrial machinery and plant engineering. The synchronous reluctance motors achieve this by offering optimized vector control, generator operation optimized in terms of energy efficiency and dynamic response, as well as safety features and technology functions. Profibus and Profinet interfaces enable integration into the Totally Integrated Automation landscape. www.siemens.com MDA Technologies 5/2016

Particularly compact and compliant with standards: TMSx tank series The developers of Bosch Rexroth have realized a compact design with a diameter of just 330 mm and a height of 480 mm. The new oil tank complies with all relevant standards of the European railway industry and offers an uncomplicated and versatile solution. The TMSx tank is particularly designed for application in rotary drives like hydrostatic traction, fan, generator or compressor drives.

The TMSx-16 frame size has a filling volume of just 10,6 l and can be used for applications with a system volume of up to 70 l. Thanks to a reduced oil filling, less oil is required per oil exchange. The reservoir is made of steel and offers various options for level monitoring of the fluid. Medium temperatures between -30 to + 90 °C are admissible. The TMSx tank series extends the Rexroth modular system solution of pumps, motors, hydraulic blocks, valve technology and RC control systems for railway vehicles. www.boschrexroth.com Minimal dimensions with a wide range of interfaces b-plus offers a flexible and powerful controller b-CANCubeMini especially designed for the application in mobile machines. Apart from the application as stand-alone, C-programmable controller, the b-CANCubeMini can also be used as a generic CANopen® Slave E-/A-Module (CiA DSP401). To benefit from the decentralized control structure, it is also possible to use it as CAN-J1939-Slave for processing the in- and outputs over parametrizable CAN-Bus messages. The 11 multifunctional in- and outputs offer the required flexibility for reacting to machine requirements. Apart from the evaluation of digital and analog signals, for example current and resistance measurement, all outputs can take up to 4 ampere load. With the test according to the ECE-R10 regulation, the protection class IP54 and an operating temperature range from -40 up to 85 °C, the controller is perfect for the use in mobile machines. www.b-plus.com High flow rate with small size Emerson has introduced the ASCO Numatics 651 Series filter, regulator, and lubricator (FRL) line of air preparation products.

It is with a view to these applications that Klüber Lubrication has developed the new, electroconductive Klüberlectric BQ 72-72. Due to an innovative lubricant design involving dissolved chemical additives, bearings run smoothly and the grease’s conductivity is considerably increased to attain specific electrical resistance characteristics resembling those of semiconductors. In rolling bearings, currents passing through them can provoke considerable damage to the inner and outer ring as well as the rolling elements. Additionally, there is a risk that the lubricant might be damaged and its performance impaired by the energetic impact. The innovative lubricant additives used in Klüberlectric BQ 72-72 not only contribute to better conductivity, but they also protect the components against wear for a longer bearing life. This was proven by positive results of bench tests and subsequent tribological component and used lubricant analyses. www.klueber.com MDA Technologies 5/2016
