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： An actuator comprises a driving section driven and rotated by a supplied current, a pump mechanism driven by a driving force supplied from the driving section to suck and discharge pressure oil, and a cylinder mechanism having a piston displaceable by the pressure oil supplied from the pump mechanism. When a pressure of the pressure oil is at or greater than a predetermined value in the cylinder mechanism, a relief valve provided in the pump mechanism is opened to thereby discharge the pressure oil into a pressure oil-charging chamber of the pump mechanism. Pressure within a first or second cylinder chamber of the cylinder mechanism and into which the pressure oil is introduced is maintained substantially constant.

摘要： A guide mechanism is provided with first guide rails each having a circular arc-shaped cross section to be installed to first long grooves each having a circular arc-shaped cross section formed on an inner wall surface of a frame, and second guide rails each having a circular arc-shaped cross section to be installed to second long grooves each having a circular arc-shaped cross section formed on side surfaces of a slider opposed to the inner wall surface of the frame. Accordingly, the arrangement of ball-rolling grooves in the slider can be performed more freely, and it is possible to mitigate the concentration of stress exerted by external force.

摘要： A rotary driving source is connected to one end of a frame. The rotary driving force of the rotary driving source is transmitted to a slider by the aid of a driving pulley, a belt member, and a driven pulley. The slider is displaced in the axial direction of the frame while being guided by a guide mechanism. Each of the frame and the slider is formed of, for example, an aluminum alloy. First guide rails are installed in the frame and second guide rails are installed in side surfaces of the slider. The first guide rails and the second guide rails are formed of a metal material subjected to a hardening treatment.
