    • A sun tracking solar energy collection system can include torque tubes that can be configured to allow the cylindrical body of one torque tube to nest with projections extending from an adjacent torque tube. The torque tubes can be formed with a plurality of rotatable shafts connected to each other in an end to end fashion. The torque tubes may be connected with coupling flanges, shaped with a plurality of radially extending lobes. The coupling flanges can include a plurality of concave portions disposed between adjacent lobes. The rotatable shafts can be round and the concave portions can be curved with a radius of curvature that is about the same as a radius of curvature of outer surface of the rotatable shafts. The torque tubes can also have saddle mounts which can include a concave portion configured to nest with an adjacent torque tube.
    • 太阳跟踪太阳能收集系统可以包括扭矩管,其可被配置为允许一个扭矩管的圆柱体与从相邻扭矩管延伸的突起嵌套。 扭矩管可以形成为以端对端的方式彼此连接的多个可旋转轴。 扭矩管可以与成形为多个径向延伸的凸缘的联接凸缘连接。 联接凸缘可以包括设置在相邻凸角之间的多个凹部。 旋转轴可以是圆形的,并且凹部可以以与可旋转轴的外表面的曲率半径大致相同的曲率半径弯曲。 扭矩管还可以具有鞍形安装件,其可以包括构造成与相邻扭矩管嵌套的凹部。
