具有高长度与直径比的滚子的双排圆柱形滚子轴承
摘要：
本发明涉及具有高长度与直径比的滚子的双排圆柱形滚子轴承。具体而言，提供了一种用于连接到周转轮系布置的托架的行星齿轮箱，周转轮系布置具有单个输入和单个输出，且包括太阳齿轮(80)、环形齿轮(86)和可在圆柱滚子轴承上旋转的至少一个双螺旋行星齿轮(84)，其中各个圆柱形滚子(104)的长度与直径比超过1.0。燃气涡轮发动机(10)包括将压缩机区段的压缩机(22)联接到涡轮区段的涡轮(30)的轴(36)。周转轮系布置具有来自联接到太阳齿轮(80)的轴(36)的单个输入、来自托架的单个输出，其联接到风扇(38)的轴(45)，且包括具有圆柱形滚子(104)的行星齿轮箱，圆柱形滚子(104)具有超过1.0的长度与直径比。
摘要（英）：

The invention relates to a double row cylindrical roller bearing with high length to diameter ratio rollers. A planet gearbox is provided for connection to a carrier of an epicyclic gearing arrangement with a single input and single output and including a sun gear(80), a ring gear(86) and at least one double helix planet gear(84) rotatable on a cylindrical roller bearing wherein the ratio of each cylindrical roller(104)'s length to each cylindrical roller's diameter exceeds 1.0. A gas turbine engine(10) includes a shaft(36) coupling a compressor(22) of a compressor section to a turbine(30) of a turbine section. An epicyclic gearing arrangement has a single input from the shaft(36) coupled to a sun gear(80), a single output from the carrier that is coupled to the shaft(45) of a fan(38) and includes a planet gearbox with cylindrical rollers(104) having a length-to-diameter ratio exceeding 1.0.
