Presents Drivetrain Diagnostics System
With OnCare.Health Vorecon, Voith presents a new data diagnostics system that goes one step further than conventional machine protection systems do. It learns, monitors, and performs diagnostics in real time. By means of typical signal patterns, the system first learns the reference state of the machine. Then it continuously monitors, records, analyzes, and evaluates the relevant signals.
With the help of signal and trend analyses, the system predicts the future behavior of the machine. Significant changes are recognized and reported long before an alarm is triggered or a fault occurs. However, if faults do arise, their root causes can be quickly and precisely analyzed and eliminated based on the data.
An easily accessible and user-friendly interface helps the user to keep an eye on all operating data, times, and states of the Vorecon. The user thus receives in-depth knowledge about the machineâ€™s behavior under various conditions. From the data in OnCare.Health Vorecon, Voith generates a monthly service report containing extensive performance diagnostics for the machine, including a servicing and maintenance recommendation. This not only ensures optimal stocking of spare parts but also allows service to be scheduled based on the machine state and not according to a fixed cycle. OnCare.Health Vorecon thus helps to increase the availability of the relevant drivetrains and at the same time lowers maintenance costs.
OnCare.Health Vorecon can be easily installed locally and connected via fieldbus to existing IT infrastructures. An internet connection is not required. Data are also not saved in a cloud. The communication channels meet the highest security standards required for critical infrastructures.
Updates Bearings App
SKF has updated the app that gives users instant information on super-precision bearings. Super-precision manager app allows users to scan a code on the product packaging, or on the bearing itself, to access product data, mounting instructions and measurement reports. It also includes information on when and where a bearing was manufactured, for enhanced traceability.
The app has been updated with a new bearing matching function which enables each user to retrieve bearing data and combine universally matchable bearings into sets. This choice is critical when for example mounting bearings in spindle applications. The matched sets can be saved into a report for later use or documentation. The function has been added to the app following requests from customers.
â€śThe app makes life easier because it saves time when accessing information,â€ť says Sten Thunberg, project manager at SKF. â€śIt also makes the documentation process much more efficient. There is less chance of human error, because data is not transcribed manually.â€ť
Super-precision manager app is available in 15 languages, including both simplified and traditional Chinese. The app is typically used in machine tool applications, such as spindle repair and maintenance. It can be used in a variety of job functions. Customer service staff can use it to supply detailed documentation, for instance. Similarly, service staff could use the app to see what has been built into a spindle.
Access to this type of information can be further enhanced via SKFâ€™s API (application programming interface) portal. The API connects to dataâ€‰â€”â€‰such as product characteristicsâ€‰â€”â€‰in a seamless, secure way. This allows users to build their own technical solutions around tools and machinery. Ultimately, this helps to increase the lifetime of assets and lower costs.

Faulhaber Miniature Motion Controllers
Offer Compact Design and Custom Options
With the new MC3001 motion controllers, available as MC 3001 B (board-to-board connectors) or MC3001P (28-pin plug connector), Faulhaber rounds out the MC V3.0 generation of controllers at the lower end of the performance spectrum. The controllers are extremely miniaturized and, with 1.4 amperes in continuous operation and up to 5 amperes peak current, are very powerful. They are designed as slaves for control and positioning tasks of DC-micromotors, linear DC servomotors or brushless DC-motors.
The new MC 3001 are unhoused versions of the Faulhaber motion controllers and, by means of the integrated output stage with optimized current measurement, can control DC-micromotors, linear DC-servomotors or brushless DC-motors from the Faulhaber product line from 6 to 30 millimeters. They are configured here via the Faulhaber Motion Manager software V6 (version 6.8 and higher). The EMC behavior of the new motion controllers has been certified by external laboratories.
With an overall height from 2.6 millimeters and a format from 16x27 millimeters, the new motion controllers are extremely miniaturized. They feature very high control dynamics and can be operated with 1.4 amperes in continuous operation and with up to 5 amperes peak current. With the new variants, the company has rounded off its motion controller portfolio at the lower end.
In spite of their extremely compact design, the just thumb-sized controllers feature the same functionality as well as the same interfaces (RS232 and CANopen) and encoder interfaces as the other more powerful products of the MC V3.0 generation. As an intelligent driver module, they are especially well suited for installation in customer-specific applications. The full thermal protection of the motors is ensured with the integrated thermal models and by means of the high PWM frequency.
The ideal fields of use of the new motion controllers of the MC 3001 series are applications from the areas of robotics, automation technology, machine construction as well as medical and laboratory technology. Applications in these areas often have limited space yet call for high control dynamics and high performance.
They are available in two variants: the MC3001 B can be plugged into a motherboard with three micro board-to-board connectors whereas the MC3001 P can be plugged in via a 28-pin plug connector. To help customers quickly and easily get to work on the development of their drive system, Faulhaber offers a starter kit that includes, among other things, a motherboard and makes it easier to get started. In addition, up to six different motherboard variants (depending on the variant of the motion controller and the used motor) are available. To meet specific customer needs, other boards can be created that may also include, e.g., an EtherCAT interface.
The motion controllers are designed for slave operation and can be easily and quickly combined with a number of higher-level master systems via standard interfaces.
After basic commissioning via Motion Manager, the controllers can alternatively also be operated at any time in stand-alone mode by means of integrated sequence programs.
Introduces New Tribo-Material Iglidur TX2
Igus now has the new tribo-material iglidur TX2 in its product range, which works without lubrication. Because even small excavators still need 50 liters of lubricant every year. The wound plain bearing bushings withstand very strong forces and increase wear resistance by a factor of 3.5 in load ranges with more than 100 MPa surface pressure.
Machines and agricultural vehicles: the construction or mining industries are exposed to challenging environmental conditions every day. Cold, heat, dust and dirt have a strong effect on the bearing points. The motion plastics specialist igus offers an alternative to frequently used metallic solutions with its plain bearing technology. Another material combination for wound bushings complements the range of injection-molded bearings in the heavy-duty range.
The tribo plain bearings made of high-strength filament fabric are used where very high loads occur. Here, the extremely strong filament in its specially interwoven design ensures maximum resistance and enables a maximum permissible compressive strength of 400 MPa. The newly developed material was extensively tested on the indoor and outdoor test rigs in the 3,800 square meter Igus test laboratory. Pivot tests on hard-chrome shafts showed that iglidur TX2 is around 3.5 times more wear-resistant than the standard heavy-duty material TX1. Like all iglidur plain bearings, iglidur TX2 is self-lubricating and operates dry. This prevents dirt from adhering to the bearing points. This reduces maintenance and repair costs, as well as machine failures due to insufficient lubrication. As the material is also very resistant to temperature, chemicals and moisture, plain bearings made of iglidur TX2 can be used in many other areas. Due to the freedom from corrosion and seawater resistance, they can also be used, for example, in moving applications in the maritime sector.
Diameters of up to 2,800 millimeters are feasible. In any case, the application of iglidur TX2 takes into account increased sustainability requirements, both underwater and onshore. â€śFor example, according to the operators, even a small excavator needs between 50 and 60 liters of lubricants per yearâ€ť, clarifies Stefan Loockmann-Rittich, head of the iglidur plain bearing technology business unit at Igus. â€śSince the iglidur TX2 bearings do not need lubrication, the customer benefits threefold: not only saving costs for oil or grease and maintenance time, but also no lubricant is released into the environment.â€ť iglidur TX2 is available from May as a standard product range in the diameters 20 to 80 millimeters directly from stock.
