Data from the condition monitoring system are analyzed either in the Schaeffler Cloud or in a local entity and displayed as plain text Data analyses permit higher average speeds, improved operational performance and longer maintenance intervals for future train generations while also improving operating safety. How do high-speed trains get to be so fast? How can public transport work on such short cycle times? How can rail transport become more reliable and safer? Schaeffler will be answering these questions at the 2016 InnoTrans 2016, in Building 21, Booth 402. Gearbox bearings specially developed for high-speed traffic, robust bearing units for the axleboxes in freight trains, and rail-specific condition monitoring systems connected to the Cloud – at the 2016 InnoTrans, Schaeffler will be demonstrating new technological solutions that increase efficiency and safety in rail transport. Predictive Maintenance For the digitalized monitoring of bogies in passenger trains, Schaeffler will present condition monitoring systems (CMS) with added value. Data analyses permit higher average speeds, improved operational performance and longer maintenance intervals for future train generations while also improving operating safety. Sensor units specially designed for railway applications are used to measure structure-borne sound, temperature and speeds on the axlebox bearings. In addition, the traction motor and gearbox can be monitored on a motorized bogie by means of vibration measurement. CMS data are analyzed either in the Schaeffler Cloud or in a local entity and displayed as plain text. Unlike a conventional CMS, the customer is not required to have vibration-specific expertise or to perform manual evaluations. The operator or maintenance technician is connected to the Cloud and can monitor the condition of individual axlebox bearings and even entire axleboxes and bogies. Expertise for the overall system The exhibit of a complete axlebox shows conventional, mechanical rail technology that has been developed further in many aspects, making the overall system more efficient and safer. The design of FAG tapered and cylindrical roller bearings for gearboxes has been optimized for high-speed traffic. Both are now able to withstand much higher speeds as well as vibration and shock loads. The one-piece machined brass cage allows the cylindrical roller bearing to withstand high radial and tangential loads. Even under high dynamic loads, the gearbox bearing can be used considerably longer. In the traction motor, coated FAG deep groove and cylindrical roller bearings provide insulation against electric current. At the InnoTrans, Schaeffler will be introducing a new Insutect A coating that offers a disruptive strength of up to 5000V DC with a layer thickness of 700 μm. The tried-and-tested TAROL axlebox bearing units, consisting of a tapered roller bearing and adjacent components, have also been developed further especially for applications in interurban high-speed trains. More robust and durable The “High Capacity TAROL Class K“, an axlebox bearing for heavy freight traffic, combines a 30 percent higher axle load with at least double the service life. This performance increase is achieved by a range of measures, such as the Mancrodur case hardening steel developed by Schaeffler. Customers do not have to adjust their adjacent construction and can easily retrofit this easy-to-install unit. Another exhibit proves how robust and durable FAG’s TAROL tapered roller bearing units really are: They have been in use in the Metro vehicles in Instanbul, Turkey, since 1987 and have completed a total of 2.7 million kilometers.
