Description

单侧双驱精准定位传动装置
技术领域
本发明涉及一种单侧双驱精准定位传动装置，广泛用于各种传动机构，特别是太阳能光热发电跟踪系统的传动机构。
背景技术
目前，在太阳能光热发电的跟踪系统俯仰角传动中，大量采用回转支承结构的单蜗杆传动减速器，其优点是传动比大，传动平稳、可以自锁，可以承受轴向力、径向力和倾翻力矩。缺点是：1、蜗轮蜗杆无论精度做的多高都会存在啮合间隙，否则会发生卡死不能转动，况且精度太高时加工成本也会很大，因而太阳能镜片由于啮合间隙而容易晃动，影响发电效率；2、在太阳能镜片的俯仰运动中，由于在重力和风力的作用下，需要很大的转动扭矩，而单蜗杆传动往往不能满足需要。
发明内容
本发明所要解决的技术问题是针对上述现有技术提供一种单侧双驱精准定位传动装置，它能在不提高蜗轮蜗杆加工精度加工成本的前提下，消除间隙精准定位，提高跟踪精度；同时由于双蜗杆设计，可以实现大扭矩传动；双蜗杆同侧设置，使结构紧凑，方便太阳能镜片的布置。
本发明解决上述问题所采用的技术方案为：一种单侧双驱精准定位传动装置，它包括基座，所述基座内通过轴承设置有回转齿轮，所述回转齿轮上左右平行设置有第一齿圈和第二齿圈，所述回转齿轮下方左右平行设置有第一蜗杆和第二蜗杆，所述第一蜗杆和第二蜗杆分别与第一齿圈和第二齿圈相啮合，所述基座外侧设置有第一电机和第二电机，所述第一电机和第二电机分别驱动第一蜗杆和第二蜗杆。
所述回转齿轮左右两侧为平面，所述回转齿轮的左右两个侧面上开设有螺孔。
与现有技术相比，本发明的优点在于：
本发明一种单侧双驱精准定位传动装置，它能在不提高蜗轮蜗杆加工精度加工成本的前提下，消除间隙精准定位，提高跟踪精度；同时由于双蜗杆设计，可以实现大扭矩传动；双蜗杆同侧设置，使结构紧凑，方便太阳能镜片的布置。
附图说明
图1为本发明一种单侧双驱精准定位传动装置的结构示意图。

图3为图1的B-B剖视图。
其中：
基座1
回转齿轮2
第一齿圈3
第二齿圈4
第一蜗杆5
第二蜗杆6
第一电机7
第二电机8。
具体实施方式
以下结合附图实施例对本发明作进一步详细描述。
如图1~图3所示，本实施例中的一种单侧双驱精准定位传动装置，它包括基座1，所述基座1内通过轴承设置有回转齿轮2，所述回转齿轮2上左右平行设置有第一齿圈3和第二齿圈4，所述回转齿轮2下方左右平行设置有第一蜗杆5和第二蜗杆6，所述第一蜗杆5和第二蜗杆6分别与第一齿圈3和第二齿圈4相啮合，所述基座1外侧设置有第一电机7和第二电机8，所述第一电机7和第二电机8分别驱动第一蜗杆5和第二蜗杆6；
所述回转齿轮2左右两侧为平面，所述回转齿轮2的左右两个侧面上开设有螺孔作为输出法兰。
当系统需要回转齿轮转动时，则两个电机同方向旋转，使两根蜗杆同步出力，实现大传动扭矩输出，当系统需要停止定位时，则第一电机停止转动，第二电机由电控系统指示短时间反向运转，使第一蜗杆的左齿侧面、第二蜗杆的右齿侧面分别与齿轮的齿侧面接触，从而实现精准定位。
除上述实施例外，本发明还包括有其他实施方式，凡采用等同变换或者等效替换方式形成的技术方案，均应落入本发明权利要求的保护范围之内。
