目前太阳能光伏跟踪应用比较普遍的是平单轴跟踪***,在平单轴跟踪***中,大多数还是采用回转减速器或者电动推杆单点驱动的方式,即由一个减速机或者电动推杆单点驱动整个主轴的回转,此形式目前在国内外被广泛采用,其特点是结构简单,安装方便,缺点是仅仅只有驱动位置一个锁紧保护点,在遇到大风的情况下容易造成驱动损坏或者主梁管的扭曲破坏。近来,越来越多的跟踪厂家开始探索单主梁多点平行驱动的跟踪***,即多个回转减速机或者推杆同步驱动一个主梁回转的方式。但目前市场上的回转减速机要实现多个回转同步平行驱动的功能还存在着一些问题,使用多个带驱动电机的回转串联的方式,需要解决多台电机驱动的同步性问题,这一点比较困难。

可选的,所述蜗杆通过左右两个蜗杆轴承设置于轴壳内,所述蜗杆轴承外侧设置有密封组件。
可选的,所述第一伞齿轮和第三伞齿轮采用直锥齿或弧齿。
可选的,所述齿轮轴和输出轴均为双向输出轴。
与现有技术相比,本发明的优点在于:
