A screw pitch feedback mechanism comprises a support, two guide rods, a sliding block, a transmission chain wheel assembly, a tensioning chain wheel assembly, a supporting chain wheel assembly and a roller assembly, the support comprises two vertical frames and a transverse frame, and the transverse frame is arranged between the bottoms of the two vertical frames; two guide rods arranged side by side are arranged between the two vertical frames, a sliding block is in sliding fit with the two guide rods, and the top of the sliding block is connected with the bottom of the feedback ring. A push-pull rod is arranged on the side wall of the feedback ring, the front side and the rear side of the feedback ring are each provided with a roller assembly, the roller assemblies are connected with sliding blocks, the bottoms of the sliding blocks are connected with the tops of chain clamps, and the chain clamps are meshed with a chain. The pitch feedback mechanism composed of the pitch potentiometer and the pitch scale plate can indicate pitch angle mechanical displacement in real time and synchronously feed back pitch angle electric signals, and pitch closed-loop control is achieved.
一种螺距反馈机构,所述螺距反馈机构包括支架、两个导向杆、滑块、传动链轮组件、张紧链轮组件、支撑链轮组件与滚轮组件,所述支架包括两个竖直架与横向架,两个竖直架底部之间设置有横向架;所述两个竖直架之间设置有两个并排设置的导向杆,滑块与两个导向杆滑动配合,滑块的顶部与反馈环的底部连接;所述反馈环的侧围上设置有推拉杆,反馈环的前后两侧各设置有一组滚轮组件,滚轮组件与滑块连接,滑块的底部与链卡的顶部连接,链卡与链条啮合。本设计螺距电位计与螺距刻度板组成的螺距反馈机构能实时指示螺距角机械位移,并同步反馈螺距角电信号,实现螺距闭环控制。
