Abstract: PURPOSE: An outer mold for manufacturing a guide beam is provided to reduce the manufacturing cost thereof and to improve the surface state of the guide beam by attaching silicon rubber having a high thermal expansion rate with a low strength to the outer mold. CONSTITUTION: A guide beam has a rectangular pipe(10a) made of aluminum. Complex material(10b) is attached to an outer surface of the rectangular pipe(10a). The guide beam is used for conveying parts. Since the surface of the complex material(10b) acts as a guide surface when the parts are conveyed, the surface of the complex material(10b) has to be finely processed. In order to improve the function of an article and to reduce the manufacturing processes, a pressing member is attached to the outer mold. The strength of the guide beam is calculated so as to determine the thickness and angle of the rectangular pipe(10a) and the complex material(10b). After attaching the complex material(10b) to the outer surface of the rectangular pipe(10a), a silicon rubber plate(24) is placed in an outer mold(22). Then, a mold cover is coupled to the outer mold(22) by means of a bolt.

Abstract: PURPOSE: A composite material ball screw is provided to improve a damping efficiency by inserting a composite material shaft member into the center of the screw and to stably drive at a high speed by increasing natural frequency. CONSTITUTION: A composite material ball screw includes a hollow shaft(11) having a screw thread(15) on an outer circumference and a composite material shaft member(12) fixed in the center along an axial direction to have a space for forming sliding friction with an inner surface of the hollow shaft through the vibration. Since the composite material shaft member is fixed only at both ends of the hollow shaft, vibration energy is vanished to friction energy due to sliding friction between the inner surface of the hollow shaft and the outer surface of the composite material shaft member to make the attenuation action become large.

The rectilinear coupler is formed as the same to a coupler(4) with RTM(Resin Transfer Molding) method or compress molding method by using the composite materials. Moreover, the rectilinear coupler is installed on a circumference face inserting a combining groove(50) of a clamp shape to pin-connect to the inner diameter of the composite material pipe. The coupler is inserted to the inner diameter of the composite material pipe inserting a pin(13) toward diameter direction, and rotates by being hooked to the combining groove of the clamp shape. Thereby, the coupler assembles a vertical unit of the scaffold system easily operating in a high building by vertically connecting the composite material pipe with the pin.
