New SKF high-capacity cylindrical roller bearings for wind turbine gearboxes have been engineered to promote longer gearbox service life and optimized performance.
用于风力涡轮机齿轮箱的新型SKF高载荷圆柱滚子轴承经过精心设计，可优化齿轮箱的性能并延长使用寿命。
Bearings can accommodate up to three more rollers (depending on dimension series and size) than standard cylindrical roller bearings usually specified for wind turbine gearboxes, according to the company’s press release. This increases load-carrying capacity and reliability of bearings and gearbox.
根据该公司的新闻稿，新型轴承可以容纳比通常为风力涡轮机齿轮箱开发的标准圆柱滚子轴承多三个滚子（取决于尺寸系列和尺寸），增加了轴承和变速箱的承载能力和可靠性。
The design, includes a low cross-section cage, virtually eliminating the risk of damage by roller-to-roller smearing, which is a common failure mode in bearings typically specified for wind turbine gearbox applications.
该设计包含一个低横截面保持架，有效避免了滚子间涂抹造成的损坏风险，该风险是轴承中常见的故障模式，常见于风力涡轮机齿轮箱中。
The cage design allows room for oil passage, which lubricates contacts between rollers and raceways, provides better cooling, and reduces risk of metal-to-metal contact that otherwise could result in smearing and surface wear. The inner ring shoulder-guided cage particularly supports good rolling behavior, especially in low load conditions, reducing the risk of cage slip.
保持架设计为油道留出了空间，润滑了滚子和滚道之间的接触，提供了更好的冷却，并降低了金属间接触的风险（金属接触可能会导致涂抹和表面磨损）。内圈挡边导向保持架拥有良好的滚动性能，特别是在低负载条件下，降低了保持架打滑的风险。
Optimized cross-sections of the rings and rollers significantly minimize the potential for fretting corrosion, ring creep, and flange fracture, compared with other high-capacity bearings.
与其他高载荷轴承相比，套圈和滚子的优化横截面显著降低了微动腐蚀、套圈蠕变和法兰断裂的风险。
