Title: Rustproof-coated pc strand and rustproofing method therefor
Inventor: ROKUSHA HIROMU
IPC: E01D11/04
Filed: 1993-12-02
Abstract: PURPOSE:To easily and completely fill a synthetic resin rust-proofing agent into the internal voids of a multi-twist PC strand. CONSTITUTION:A PC strand is made by twining plural side wires 3 around a core wire 2. As part or the whole of these side wires 3, a modified cross-section PC steel material with an uneven design formed monolithically on its outer peripheral surface is used, and the PC strand, under heating, is threaded into a synthetic resin extruder where a molten thermoplastic synthetic resin material is pressed into from between the respective side wires to the outer periphery of the core wire while pressurizing the molten resin with the pressure head of the extruder, and the molten resin, together with the PC strand, is extruded through the molding die at the tip of the pressure head, thus obtaining a rustproof-coated PC strand 1 with rustproof-coating layer 5 consisting of the thermoplastic synthetic resin adhered firmly to the whole periphery of both the core wire 2 and the respective side wires 3. Owing to the use of a modified cross-section steel material as the side wires, the voids between the side wires communicating with the internal void developed between the outer periphery of the core wire and the side wires are large and also nearly uniformly formed. Therefore, molten resin flows into the PC strand smoothly and uniformly.

Abstract: PROBLEM TO BE SOLVED: To provide a spherical joint of low friction free from play. SOLUTION: Oil grooves to surround the whole circumference of the load surface at the opposite position by 180 deg. to either of inner or outer rings are provided so that an inner ring 2 and an outer ring 6 are rapidly brought closely to each other by the load when the frequency is increased, the lubricating oil on a load surface 3-1 whose circumference is surrounded by oil grooves 13-1, 13-2 is removed by the access velocity of the inner ring 2 and the outer ring 6 to generate the dynamic pressure, two surfaces are difficult to be brought closely to each other and it takes time for the access. The displacement is not changed stepwise but changed gradually by switching the positive and negative oscillation force to realize the characteristic of the spring support free from a play, and the distortion is difficult to generate in the acceleration waveform. All or most of the load is borne by the hydrostatic and dynamic pressure, and the friction force is greatly reduced because the load to be borne in a non-contact and contact manner is reduced. Reduction in the friction force contributes to the reduction of the acceleration distortion, and damages such as seizure and wear can be prevented due to the non-contact bearing or due to small contact load even when being brought into contact.
