Production manner elastic body of revolution for fixation and elastic body of revolution null for its fixation

摘要

PURPOSE:To stabilize wear resistance and durability by calcining resin layers on elastic material layers while maintaining said layers at the temp. lower than the temp. of resin materials and heating the same to the high temp. at which the resin materials can be calcined then quickly cooling the same, thereby forming the resin film layers. CONSTITUTION:The resin layers are calcined on the elastic material layers while said layers are maintained at the temp. lower than the temp. of the resin materials and are heated to the high temp. to permit the calcination of the resin materials and are then quickly cooled to form the resin film layers in the stage of forming the resin layers on the elastic material layers 12, 22 by calcining the resin materials 13, 23 thereon. The surface temp. of the resin layers held higher than the temp. of the elastic material layers until the temp. of the elastic material layers attains the temp. near the service temp. of the rotating bodies 1, 2 in quick cooling. Both the resin layers and elastic material layers are thereafter cooled while said layers are kept at about the same temp. The wear resistance and durability of the elastic rotating bodies are thereby stabilized.
