The invention discloses a speed limiting device which comprises a shell, a speed reducing mechanism, a roller mechanism and a roller pressing mechanism, wherein the shell is provided with a containingspace, and non-Newtonian fluid is arranged in the containing space in a sealed mode; the speed reducing mechanism comprises a rotating sleeve and a rotating vane arranged on the rotating sleeve; theroller mechanism comprises a first roller and a second roller, the first roller is connected with the rotating sleeve, and the second roller and the first roller are oppositely arranged on two sides of a workpiece; and the roller pressing mechanism is connected with the second roller and is used for enabling the second roller to press the workpiece. When speed limiting is needed, the speed limiting device is installed on equipment to clamp the workpiece, the workpiece drives the first roller and the second roller to rotate passively, the rotating vans also rotates passively, and non-Newtonianfluid is stirred. When high-speed stirring is carried out, the resistance is rapidly increased, so that the rotating speed of the rotating vane is forced to be reduced, a speed limiting effect is achieved, and various devices can be ensured to run at a rated speed without overspeed.

    本发明公开了一种限速装置,其包括壳体、减速机构、滚轮机构和滚轮压紧机构。其中壳体具有容纳空间,所述容纳空间内密封地设置有非牛顿流体;减速机构包括转套和设于转套上的转叶;滚轮机构包括第一滚轮和第二滚轮,第一滚轮与转套连接,第二滚轮与第一滚轮相对设置在工作物两侧;滚轮压紧机构第二滚轮连接,用于使第二滚轮压紧工作物。当需要限速的时候,将本发明安装在设备上,夹住工作物,工作物带动第一滚轮和第二滚轮被动旋转,导致转叶也被动旋转,搅拌非牛顿流体。当高速搅拌时,阻力迅速增大,导致转叶的转速被迫下降,从而起到了限速的作用,能够保证各种设备,处于额定速度内运行,不会超速。
