Abstract
Official abstract text for this publication.
A method for manufacturing a cogged V-belt having a plurality of cogs, includes: an unvulcanized sleeve formation step of forming an unvulcanized sleeve by laminating a plurality of unvulcanized rubber sheets that contain at least an unvulcanized rubber sheet for a compression rubber layer and an unvulcanized rubber sheet for a tension rubber layer; a vulcanized sleeve formation step of forming a vulcanized sleeve by vulcanizing the unvulcanized sleeve; and a cog formation step of forming the plurality of cogs on the compression rubber layer after the vulcanized sleeve forming step.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for manufacturing a cogged V-belt having a plurality of cogs on a belt inner peripheral side, which cogs are arranged each extending in a belt width direction and spaced apart from each other in a belt longitudinal direction, the method comprising: an unvulcanized sleeve formation step of laminating a plurality of unvulcanized rubber sheets comprising at least an unvulcanized rubber sheet to be a compression rubber layer disposed on the belt inner peripheral side and an unvulcanized rubber sheet to be a tension rubber layer disposed on a belt outer peripheral side, thereby forming an unvulcanized sleeve; a vulcanized sleeve formation step of vulcanizing the unvulcanized sleeve after the unvulcanized sleeve formation step, thereby forming a vulcanized sleeve; and a cog formation step of forming the plurality of cogs by water jet-processing the compression rubber layer after the vulcanized sleeve formation step, wherein the unvulcanized sleeve formation step further comprises laminating to each other a plurality of sheet members, which each contain short fibers oriented in the belt width direction, the laminated plurality of sheet members forming the unvulcanized rubber sheet for the compression rubber layer, and laminating the unvulcanized rubber sheet, which is for the tension rubber layer, on the unvulcanized rubber sheet, which is for the compression rubber layer. 2. The method for manufacturing a cogged V-belt according to claim 1 , wherein the unvulcanized sleeve formation step further comprises: laminating an unvulcanized rubber sheet to be an adhesion rubber layer on the unvulcanized rubber sheet for the compression rubber layer, wherein the laminating the unvulcanized rubber sheet, which is for the tension rubber layer, on the unvulcanized rubber sheet, which is for the compression rubber layer, comprises laminating the unvulcanized rubber sheet, which is for the tension rubber layer, on the unvulcanized rubber sheet, which is for the adhesion rubber layer. 3. The method for manufacturing a cogged V-belt according to claim 2 , wherein the unvulcanized sleeve formation step further comprises disposing a cord extending in the belt longitudinal direction in the unvulcanized rubber sheet for the adhesion rubber layer.
