Drive technologies belt,

Drive technologies belt, the crushed material was transported up to the gravel plant, where it was stored or used as construction aggregate for the dams or for construction concrete. Over a total of three years, these conveyors transported approximately one million tons of material. Located right and left of this conveyor system and connected by a common shaft, two Nord industrial gear units generated a belt speed of 2.2 m/s. With a protection class of IP55, these industrial gear units each have a drive power of 250 kW. The industrial gear units for this massive construction project were developed based on the tried-and-tested Unicase design: the one-piece housing block integrates all bearing seats. Unicase housings are manufactured on state-of-the-art CNC machines in a single setting. The concept features high precision, rigidity, and strength with no joints between the output side and the gearcase which are subject to radial forces or torque. What is more, the overlapping bearing offset allows for more compact gearcases and larger roller bearings that guarantee a long operating life. Industrial gear units can be right or left mounted. Customer-oriented drive solutions The supplier of this complete drive solution was Getriebebau Nord AG, Switzerland – a member of the Nord Drivesystems Group. The drive specialists from Arnegg near St. Gallen place much value on customer orientation and proximity. Guido Eigenmann, Manager of Getriebebau Nord AG, Switzerland, says: “We sell customer benefits – not just products. We offer a comprehensive service package and provide maintenance training, so that the customer knows what to look out for. It is particularly important for us to supply complete systems which are highly efficient and economical. Many users require not just drive components, but rather complete and functioning system solutions. We tailor our drive solutions to each individual application.” Nord Drivesystems was commissioned by the plant constructor Marti Technik AG. Founded in 2002, the international technology company is one of the many subsidiaries of the Swiss Marti Holding AG. Marti Technik AG is a provider of individual tailor-made solutions focusing on underground construction work. After the completion of the conveying tasks, the Nord industrial gear units were disassembled by Marti Technik AG, and are now awaiting their next assignment. Ernst Kuster, head of maintenance and responsible for the conveyor systems at Marti Technik, says: “In compliance with the instruction manual, we changed the oil once, but that was the only maintenance measure we had to take over the course of three years. The Nord gear units performed brilliantly. Nord Drivesystems has cooperated with us very well. All of our requirements were catered for. The short delivery time is also remarkable – it only took about ten weeks from ordering to delivery of the built-to-order drives. All in all we are very satisfied – a very good cost-benefit ratio, excellent advice and support, and on-schedule delivery.” 05 Nord SK 12407 industrial geared motor with brake function and energy recovery (upper conveyor belt) Industrial gear unit in a UNICASE housing Currently available in eight sizes in Unicase housings, Nord Drivesystem’s powerful industrial gear units cover smaller frames for torques from 25,000 Nm to large models up to 242,000 Nm. In this series, a single standard housing per frame size spans the entire transmission range. A highly flexible and modular concept provides countless options for straightforward and fast configuration for individual models. If required, Nord assembles complete drive trains for users, including swing bases with gear units and motors as well as options such as drum brakes, fluid clutches, fans, and auxiliary drives. Even the largest industrial gear units are manufactured to Nord’s one-piece Unicase concept: all bearing seats and sealing surfaces are machined in a single stage on state-of-the-art CNC machining centers. The benefits include extremely high reliability and exceptional sealing with safe handling of even the largest torques; combined with high axial and radial load bearing, quiet running, low maintenance and an exceptionally long operating life.

Nanotec introduces programmable motor controller The company Nanotec Electronic GmbH & Co. KG has developed a controller specifically for the open loop control of stepper motors sized Nema 17 to Nema 34, which can be parameterized and programmed via USB. The C5 controller is especially suited to simple applications that do not require an encoder but rather high dynamic performance and smooth running, such as CNC dental milling machines. It can be operated via clock-direction mode or through specification of the speed or position via the analog input. It also supports sequence programs that are directly executed in the motor controller. Programs developed in NanoJ, based on C++ run as machine code in the controller and are synchronized via a real-time operating system in 1-ms cycles with digital inputs and outputs, including the instructions received via the field bus. Frequency converter with intuitive operating concept The frequency converters Movi4R-U by SEW-Eurodrive meet the basic needs to drive technology. The manufacturer deliberately focuses on the most important functions of a converter, i.e. the simple speed control of asynchronous motors. The protection type your reliable partner EAS ® -Compact ® The airbag for your machine IP54 permits assembly outside of a control cabinet, e.g. close to the application for control of conveyor belts. The product series covers the performance range of 0.25 to 1.1 kW (3 x AC 400 V) or 0.25 to 0.55 kW (1/3 x AC 230 V). The operating button permits the setting of any device parameter via two menu levels; an LED shows the device status and informs about the cause of the error in case of interference. An operating card permits the user to handle commissioning and error diagnosis without external help or any additional product documentation. "In our high quality filling and packaging systems, we only integrate components that offer very high quality and reliability. Therefore, for overload protection, we have been relying exclusively on EAS ® torque limiters by mayr ® Antriebstechnik for several years." Markus Kröger Franz Tölke GmbH, Sondermaschinenbau.
