摘要： An epicyclic gear system (A) includes sun and ring gears (2, 4) and planet pinions (6, 8) arranged in two side-by-side arrays (a, b) between the sun and ring gears, there also being a carrier (10, 50) to which planet pinions are coupled through flexpins (30). The carrier has primary and secondary walls (20, 22) between which the pinions are located and webs (24) connecting the walls. The flexpins for one array of pinions are cantilevered from the primary wall and the flexpins for the other array of pinions are cantilevered from the secondary wall. When the gear system operates, the carrier along its primary wall is subjected to an externally applied torque which transfers through the system at the planet pinions of the two arrays. The load path (pa) for the pinions at the primary wall is shorter than the load path (pb) for the pinions at the secondary wall, and this disparity causes the carrier to distort. To compensate for this distortion so that the pinions of the two arrays will mesh more evenly with the sun and ring gears, the flexpins of the first array are offset angularly with respect to the flexpins of the second array, or the teeth of the pinions in the first array are narrower than the teeth of the pinions of the second array, or the primary wall of the carrier has areas (40, 44) of weakness where the flexpins of the first array are cantilevered from it, or the flexpins of the first array are more flexible than the flexpins of the second array. As a consequence, the pinions of the two arrays mesh better under load with the sun and ring gears and share the transfer of torque more evenly.
摘要翻译：行星齿轮系统（A）包括在太阳和环形齿轮之间布置成两个并排阵列（a，b）的太阳和环形齿轮（2,4）和行星小齿轮（6,8），还有一个行星齿轮通过柔性销（30）联接到其上的载体（10,50）。载体具有初级和次级壁（20,22），小齿轮在其之间并且连接壁的腹板（24）。一个小齿轮阵列的弹簧片从主壁悬臂，另一个小齿轮阵列的弹簧片从次级壁悬臂。当齿轮系统运行时，沿其主壁的载体经受外部施加的扭矩，其通过系统在两个阵列的行星小齿轮处传递。在主壁处的小齿轮的负载路径（pa）比在次级壁处的小齿轮的负载路径（pb）短，并且该视差导致载体变形。为了补偿这种变形，使得两个阵列的小齿轮将与太阳和环形齿轮更均匀地啮合，第一阵列的柔性针相对于第二阵列的柔性体的角度偏移，或者小齿轮的齿第一阵列比第二阵列的小齿轮的齿窄，或者载体的主壁具有第一阵列的柔性针从其悬臂的弱点区域（40,44），或者第一阵列的弹性体数组比第二个数组的flexpins更灵活。因此，两个阵列的小齿轮在负载下与太阳和环形齿轮啮合更好，并且更均匀地共享转矩传递。

摘要： An epicyclic gear system (A) includes helical sun and ring gears (2, 4) and helical planet pinions (6) located between and engaged with the sun and ring gears. The gear system also includes a carrier (8) having an end wall (12) and flexpins (20) cantilevered from the end wall and extended into the planet pinions. Each flexpin at its end remote from the end wall carries a sleeve (22) that extends back over the flexpin where it is spaced from the flexpin. The planet pinion for the flexpin rotates around the sleeve on a bearing (24). The arrangement is such that the flexpin will flex adjacent to the carrier end wall circumferentially along the pitch circle of the carrier in one direction and circumferentially in the opposite direction adjacent to attachment of the sleeve. But the helical gear imparts a couple to the planet pinion that seeks to tilt the sleeve radially toward or away from the main axis of the system. A deflection inhibitor (I) lies between each flexpin and the sleeve surrounding it to prevent the radial deflection.

摘要： An axially compact and highly integrated bevel pinion and bearing assembly (A1, A2) wherein a pinion gear (10) is integrated with a first support bearing (B1), and the pinion shaft (12) is integrated with a second support bearing (B2) axially displaced from the first support bearing (B1). With the first support bearing (B1) arranged axially under the pinion gear teeth (11), loads from the pinion gear (10) are transferred primarily through the first support bearing (B1). As a result, the second support bearing (B2) can be reduced in size and brought axially closer to the first support bearing (B1) to reduce the axial length of the pinion and bearing assembly. The integration of the pinion gear (10) with the first and second support bearings (B1, B2) optimizes material utilization and reduces overall weight of the pinion and bearing assembly, leading to a power density improvement.
摘要翻译：一种轴向紧凑且高度集成的锥齿轮和轴承组件（A1，A2），其中小齿轮（10）与第一支撑轴承（B1）成一体，小齿轮轴（12）与第二支撑轴承（B2 ）从第一支撑轴承（B1）轴向移位。由于第一支撑轴承（B1）轴向地布置在小齿轮齿（11）的下方，所以小齿轮（10）的载荷主要通过第一支承轴承（B1）传递。结果，第二支撑轴承（B2）的尺寸可以减小并且轴向更靠近第一支撑轴承（B1），以减小小齿轮和轴承组件的轴向长度。小齿轮（10）与第一和第二支撑轴承（B1，B2）的集成优化了材料利用率，并减小了小齿轮和轴承组件的总体重量，从而提高了功率密度。

The gear system also includes a carrier (8) having an end wall (12) and flexpins (20) cantilevered from the end wall and extended into the planet pinions. Each flexpin at its end remote from the end wall carries a sleeve (22) that extends back over the flexpin where it is spaced from the flexpin. The planet pinion for the flexpin rotates around the sleeve on a bearing (24). The arrangement is such that the flexpin will flex adjacent to the carrier end wall circumferentially along the pitch circle of the carrier in one direction and circumferentially in the opposite direction adjacent to attachment of the sleeve. But the helical gear imparts a couple to the planet pinion that seeks to tilt the sleeve radially toward or away from the main axis of the system. A deflection inhibitor (I) lies between each flexpin and the sleeve surrounding it to prevent the radial deflection.
