METHOD OF MANUFACTURING A PLAIN BEARING FOR A MOVABLE FUNCTIONAL PART OF SYSTHETIC RESIN MATERIAL WHILE RETAINING AN UNPERTURBED MOLECULAR STRUCTURE

摘要

According to the present invention, the bearing bridges 7 to 7f of the bearing portions 1 to 1f pass through the metal bearing plate 11 holes 3 having the hole walls, and the holding portion 9 of the bearing portion is formed to have the holes 3. In the manner of supporting both plate surfaces 11a and 11b along the lateral direction, the movable function portion is a plane for the movable function portion formed integrally with the bearing portion on the metal bearing plate by a synthetic resin injection molding technique (outsert molding technique). A method of manufacturing a bearing. The bearing parts 1 to 1f composed of the bearing bridges 7 to 7f and the holding part 9 are deformed by a deformation process following the injection molding process to form the bearing plate 11 and the rotating and sliding bearings. In the process, the bridge material is deformed by being spaced and pressurized in its central bridge area, and the deformation process is carried out under time and temperature conditions in which the resin can flow according to its specificity and maintain an unmodified molecular structure, thereby causing load resistance, Partial orientation is obtained. This orientation can be obtained by heat resistance through deformation after deformation and possibly by storage.
