In the process of early development and later performance improvement of high reliability bearings for railway trains, it is very important to fully grasp the actual usage conditions and restore them to a large extent in evaluation experiments. Ensuring the stability and riding comfort of railway vehicles is an important mission of railway bearings. According to railway gauge, wheel diameter, and axle load, wheel sets can have different configurations and designs, Due to the crucial importance of all these systems for the performance and reliability of railway vehicles, careful consideration should be given when selecting bearing solutions. The driving system used for railway trains, such as gearboxes or traction motors, must have the characteristics of strong power, sustainability, cost-effectiveness, and low maintenance requirements. Due to the increasing maintenance intervals and the increasing weight of railway vehicles, these requirements have become increasingly important.
The motor must provide high speed and withstand shock loads, and must also resist low load conditions, such as in sliding or cruise control mode. In addition, the sensitivity to discharge also poses unique design challenges for the motor bearings. These all pose high requirements for bearing configuration, with specific challenges including a larger operating temperature range, high impact loads, and an increase in overall load combined with the drive to reduce friction in the gearbox and reduce energy consumption. We offer various solutions aimed at ensuring reliable and cost-effective operations, improving fleet operational efficiency and reliability. Our railway specific products and services allow you to fully utilize the performance potential of bearings, thereby helping you reduce lifecycle costs, achieve sustainable and cost-effective operation with less maintenance in humid and polluted environments, and achieve robust, sustainable, and cost-effective railway operations.
