摘要： Helical gears are used for a sun gear, planet gears, and an internal gear. Accordingly, when a load, which exceeds a preset torque, is applied to the internal gear, the internal gear is moved in a direction toward an input shaft or a direction toward an output shaft while making rotation in a direction different from that of the sun gear to automatically switch the speed reducing ratio.

摘要： Pressed shape steel, made of a low cost general steel material that is not hardened, forms a frame with long grooves cut therein. Guide rails, made of a specialized steel material that can be subjected to a hardening treatment, are hardened. Thereafter, outer surfaces of the hardened guide rails are ground and the guide rails are integrally joined in the long grooves. Ball-rolling grooves are formed in the guide rails, thereby completing a guide-equipped frame for an actuator. Because the general steel material and the specialized steel material are principally ferrous materials, both exhibiting a Young's modulus at or above 170 GPa with substantially the same coefficient of linear thermal expansion, the frame needn't be increased in size or have a complex internal structure to reinforce the strength of the frame, and the guide rails remain securely retained in the grooves even if the actuator experiences changes in temperature.

摘要翻译： 由未硬化的低成本普通钢材制成的压制型钢形成在其中切割有长槽的框架。 由能够进行硬化处理的专用钢材制成的导轨被硬化。 此后，硬化的导轨的外表面被研磨，导轨一体地接合在长槽中。 在导轨上形成滚珠槽，从而完成用于致动器的引导装置的框架。 由于普通钢材和专用钢材料主要是铁质材料，两者都具有170GPa以上的杨氏模量，且线性热膨胀系数基本相同，所以该框架不需要增加尺寸或具有复杂的内部结构 以加强框架的强度，并且导轨仍然牢固地保持在凹槽中，即使致动器经历温度变化。

摘要： A cable, which includes a plurality of tubes disposed continuously in the height direction, has one end which is fixed to a first cable-connecting section disposed at one end of a body of an electric actuator. The cable has the other end which is connected to a second cable-connecting section connected to a slider which is displaceable along the axis under the driving action of a rotary driving source. The cable is installed substantially horizontally with respect to the body. The dimension in the height direction is large, and the dimension in the thickness direction is small.
