Less Friction and Higher Economic Efficiency
The newly developed plastic segment cage offered by Schaeffler Group Industrial (INA/FAG) is designed to improve the economic efficiency and output of wind turbines having rotor supports according to the so-called single bearing concept. Schaeffler Group Industrial will present its new bearing cage design for the first time at HusumWind 2008 in Hall 4, Booth E10.

Currently there is a strong trend towards single bearing concepts for wind turbines since these carry less weight and require less installation efforts. The rotor head in such designs is directly bolted, for example, to the bearing outer ring so that the need for a shaft is eliminated. To date it is mainly double row tapered roller bearings with pin-type steel cage that are used for single bearing concepts. The rolling element riding bearing cage gives high stability and service long life. However, the through-boring of the rollers involves relatively high manufacturing efforts.
Higher efficiency
Schaeffler Group Industrial has therefore developed a new plastic segment cage especially for use in single bearing applications. The cage consists of single segments that are connected to each other via snap fittings. This lock ensures a defined clearance which enables the uniform expansion of the bearing cages. High-strength and lightweight PEEK is used as cage material. It can accommodate high loads while offering excellent wear resistance. Moreover the plastic segment cage reduces friction and thus increases wind turbine efficiency. The new cage design improves not only rolling element guidance, but also enables optimum lubricant supply.

减摩擦和较高的经济效率
新开发的塑料笼部分所提供的舍弗勒集团工业（冰核/ FAG ）的目的是提高经济效率和产出的风力涡轮机转子支持有根据所谓的单一轴承的概念。舍弗勒集团工业将提出新的轴承保持架的设计首次在HusumWind 2008年在4号馆，展位E10中。
目前有一种强烈的趋向单一概念，同时风力涡轮机，因为这些携带重量轻，并需要更少的安装工作。转子头在这种设计是直接螺栓，例如，轴承外圈，以便需要有一个轴消除。迄今为止，它主要是双列圆锥滚子轴承的脚型钢笼用于单个轴承的概念。滚动元件轴承保持架骑高度稳定和服务寿命长。然而，通过钻的辊涉及相对较高的制造业的努力。
高效率
舍弗勒集团工业，因此开发出一种新的塑料笼尤其是部分使用的单一轴承应用。笼子由单一的部分连接到对方通过提前配件。这锁保证了界定关，使统一的扩大轴承笼。高强度，重量轻聚醚醚酮作为笼的材料。它可以容纳高负荷同时提供良好的耐磨性。此外，塑料部分笼减少摩擦，从而增加风力涡轮机效率。新笼的设计不仅提高滚动轴承的指导，而且还可以让最佳的润滑剂供应。
