    • There are provided two kinds of nuts of a ball thread nut 20 and a non-ball thread nut 30 which is rotatable in synchronization with the ball thread nut 20 and in which a thread groove in rectangular or trapezoidal shape in section is formed. In a thread rod 10, two kinds of thread grooves are formed at the same pitch, one 11 of the thread grooves being in an arc shape in section so as to be meshed with the ball thread nut 20 through balls B and the other thread groove 12 being in a rectangular or trapezoidal shape in section so as to be meshed with the non-ball thread nut 30. When load is less than a predetermined value, the thread ridge of the non-ball thread nut 20 and the thread ridge 13 of the thread rod 10 are separated and are out of contact with each other so that the thread rod 10 is moved in the axial direction thereof by only the ball thread nut 20. In contrast, when the load exceeds the predetermined value, the thread ridge 31 of the non-ball thread nut 30 and the thread ridge 13 of the thread rod 10 are made in contact with each other so that the thread rod 10 is moved in the axial direction by the non-ball thread nut 30.
    • 提供滚珠丝杠螺母20的两种螺母和与滚珠螺母20同步旋转的非球螺纹螺母30,其中形成有矩形或梯形形状的螺纹槽。 在螺纹杆10中,以相同的间距形成两种螺纹槽,其中一个螺纹槽中的11个为圆弧状,以便通过滚珠B和另一个螺纹槽与滚珠螺母20啮合 12的截面为矩形或梯形,以便与非球螺纹螺母30啮合。当负载小于预定值时,非球螺纹螺母20的螺纹脊和螺纹螺母20的螺纹脊13 螺纹杆10被分离并且彼此不接触,使得线杆10仅通过滚珠螺母20在其轴向方向上移动。相反,当负载超过预定值时,螺纹脊31 使非螺纹螺母30和螺纹杆10的螺纹脊13彼此接触,使得螺纹杆10通过非滚珠螺母30沿轴向移动。
