Business Wire
The Timken Company (NYSE:TKR) announced today that it is the sole
authorized supplier of tapered roller bearings for the axle-riding
final drives used to transmit power to the wheels of some of
Europe�s fastest trains. The new Siemens Velaro E high-speed train
is capable of achieving speeds up to 217 miles per hour on the
Madrid to Barcelona route of Spain�s national railway. German drive
manufacturer Voith Turbo GmbH & Co. KG developed the SE-380
final drive for the Velaro E with both performance and passenger
comfort in mind. On the Velaro E, the drives are located directly
below the passenger area. For this reason, noise reduction was a
critical design objective. Voith made changes in the gearing and
housing design and sought a new bearing concept. Voith turned to
Timken for help in designing a bearing for the output shaft of the
drive that would support performance needs while being more compact
and economical than the previous cylindrical roller bearing design
used on some high-speed trains. Timken engineers designed tapered
roller bearings capable of meeting the special design requirements
and compatible with the extremely high travel speeds. �We applied
our knowledge of friction management and power transmission to take
a proven bearing design and developed it further to improve the
train�s performance, lowering weight and enhancing the passenger
experience by reducing noise," said Mat Happach, vice-president �
rail for Timken. Timken has been developing and manufacturing
products for the rail industry since the early 1930s. Its products
are found on passenger and freight lines around the world. About
