An apparatus including a shaft, a wheel cylindrically mounted on the shaft, a cylinder coaxial with the wheel and having an inner wall, and at least two centrifugal braking assemblies mounted on the wheel uniformly distributed in a circumferential direction is provided. Each centrifugal braking assembly includes a brake member pivotally mounted on the wheel and having at least one curved frictionsurface, a cam pivotally mounted on the wheel and in slidable contact with the brake member, and a spring connected between the cam and a pin mounted on the wheel. The brake member, the cam, and the spring cooperate to rotate the curved friction surface of the brake member and in turn, contact with the inner wall of the cylinder when a rotational speed of the shaft exceeds a first predetermined value. 提供了种设备，其包括：轴；轮状物，其圆柱形安装在轴上；汽缸，其与轮状物同轴并且具有内壁；以及至少两个离心制动组件，其安装在轮状物上且沿着圆周方向均匀分布。每个离心制动组件包括制动构件，其可枢转地安装在轮状物上并且具有至少个弯曲摩擦表面；凸轮，其可枢转地安装在轮状物上并且与制动构件可滑动接触；以及弹簧，其连接在凸轮与安装在轮状物上的销之间。当轴的转速超过第预定值时，制动构件、凸轮和弹簧配合以使制动构件的弯曲摩擦表面旋转并且进而与汽缸的内壁
