Innotrans 2008: Schaeffler Group Industrial in the Velaro for Russia and China InnoTrans展会2008年：德国舍弗勒集团工业Velaro在俄罗斯和中国
Axlebox Bearings for High-Speed Trains轴箱轴承的高速列车
Schaeffler Group Industrial (INA/FAG) is the development partner for the axlebox bearings incorporated in the Velaro high-speed trains destined for Russia and China.舍弗勒集团工业（冰核/ FAG ）是发展合作伙伴的轴箱轴承纳入Velaro高速列车运往俄罗斯和中国。 Its Business Unit Rail has developed one complete axlebox bearing with swing-arm housing each for the two bogie variants.其业务股钢轨已开发一个完整的轴箱轴承摆动手臂住房每两个转向架的变种。 The axlebox bearings consist of an upper and lower housing part as well as the rolling bearing; the bearing for the Velaro Russia has an additional housing ring.轴箱轴承的包括上限和下限的住房的一部分，以及滚动轴承;轴承为Velaro俄罗斯有更多的住房戒指。 The trains are scheduled to serve the Beijing-Tianjin route in China as from 2008 and will connect the Russian cities of Moscow and St. Petersburg from 2009.列车定于服务北京，天津航线，从中国2008年将连接俄罗斯城市莫斯科和圣彼得堡，从2009年开始。
TAROL units for high loads TAROL单位的高负荷
Double-row TAROL tapered roller bearing units are the core components of the heavy-duty axlebox bearing units.双排TAROL圆锥滚子轴承单元的核心组成部分的重型轴箱轴承单元。 Two different bearing sizes are used due to the different axle loads.两种不同规模的同时由于采用不同的车轴负荷。 In particular, the components for the Velaro Russia must be able to withstand extreme operating and environmental conditions.特别是，部分为Velaro俄罗斯必须能够承受极端的工作和环境条件。 The TAROL bearings are designed for loads of up to 18.5 tons and the axlebox bearing housings can be used within an extremely wide temperature range.该TAROL轴承的设计载荷可达18.5万吨，轴箱轴承座可用于在一个非常宽的温度范围内。 TAROL bearings for the Velaro Russia have a bore diameter of 150 mm and are equipped with reinforced polyamide cages. TAROL轴承的Velaro俄罗斯有镗孔直径为150毫米，并配备了钢筋笼聚酰胺。 To ensure correct installation of the bearings, Siemens fitters receive expert training by specialists from FAG Industrial Services (F’IS), the Schaeffler Group’s service subsidiary.为了确保正确安装轴承，西门子钳工得到专家的培训专家FAG工业服务（ F'IS ）中，舍弗勒集团的附属服务。 Thus the Siemens staff is certified by the Schaeffler Group and is therefore authorized to mount these axlebox bearings.因此，西门子公司认证的工作人员是由舍弗勒集团，因此，授权安装这些轴箱轴承。
The ready-to-fit TAROL units are especially easy to install and are based on double-row tapered roller bearing units.其现成的生长TAROL单位，特别是易于安装和基于双列圆锥滚子轴承单位。 During manufacture they are sealed and greased and their clearance is adjusted.在制造过程中他们是密封的greased和清除调整。 Schaeffler Group Industrial can provide the bearing units in metric and imperial dimensions, along with all the necessary components and bolts for quick and safe mounting.舍弗勒集团工业可以提供轴承公制单位和帝国层面，连同所有必要的部件和螺栓的快速和安全的安装。 Customer-specific individual parts, spare parts and housing adapters are available upon request.客户的具体各个部件，零配件和住房适配器都要求提供。
Housing structure for extreme temperatures 房屋结构的极端温度
The housing of the axlebox bearing for the Velaro Russia has been designed to resist extreme temperatures and offers a minimum impact strength of 12 joules at -50 degrees Celsius – a value that is normally reached at -25 degrees Celsius.住房的轴箱轴承的Velaro俄罗斯一直旨在抵制极端温度，并提供最低限度的冲击强度12焦耳在-50摄氏度-一个价值，通常是达到- 25摄氏度。 It is made of spheroidal graphite cast iron according to DIN EN 1563.它是由球墨铸铁按照DIN EN 1563 。 The strength of the housing structure has been optimized and confirmed using FEM (finite element method) calculations.的力量住房结构得到优化，并证实利用有限元（有限元方法）计算。 FEM describes not only complex geometries, but also the complex progression of the force flow in the housing in a realistic manner.有限元方法不仅描述复杂的几何形状，而且还发展的复杂的力量在流动中的住房以切合实际的方式。
The housing as a connecting element between the bogie and the wheelset has the task of transmitting forces reliably.住房作为一种关联因素之间的转向架和轮对的任务是转递力量可靠。 Its design depends on how the forces are introduced into the housing.它的设计取决于力量引入到住房。 The optimized shape improves the pressure distribution inside the rolling bearing so that the specific load is reduced and peak loads are prevented.形状优化的压力，改善内部分配滚动轴承，使特定负荷减少，最大负荷是可以避免的。
Distributed traction system concept for high-speed traffic 分布式牵引系统概念的高速交通
The trains for Russia and China are based on Siemens’ Velaro platform, which is a further development of the high-speed ICE 3 multiple unit concept operated by Deutsche Bahn.该列车为俄罗斯和中国是基于西门子Velaro平台，这是一个进一步发展的高速冰三多个单位的概念经营的德国铁路。 In a multiple unit train, the traction equipment and all technical modules are all arranged under floor and distributed over the entire length of the train.在一个多单元列车，牵引设备，所有技术模块都是根据安排发言和分发的整个长度的列车。 This contrasts with the push-and-pull approach where everything is packed into two locomotives coupled at the front and the rear of the train formation.与此相反，推动和拉动的办法，一切都装入两个机车加上在前面和后面的列车编组。 For the same length of train, therefore, this means an increase in seating capacity of around 20 percent as the absence of locomotives creates more space for passenger accommodation.出于同样长度的训练，因此，这意味着增加座位的百分之二十左右，没有机车创造更多的空间，旅客住宿。 The Velaro for China, for example, has room for over 600 passengers.该Velaro的中国，例如，空间，超过600名乘客。 Because 50 percent of the axles are driven directly, the train can accelerate more effectively.由于百分之五十的车轴直接驱动，列车可以更有效地加快。 Moreover, this traction concept enables the train to run on track sections with steeper gradients of up to 4 percent.此外，这一概念使牵引列车运行的轨道与陡节梯度可达百分之四。 One additional but equally important advantage is the lighter load on each axle due to the improved distribution of weight over the vehicle as a whole.另外一但同样重要的优点是较轻的负载每个车轴由于改进的重量分配的车辆作为一个整体。
