Embodiment Construction

[0055] Hereinafter, embodiments will be described in detail with reference to the drawings.

[0056] figure 1 A V-ribbed belt B manufactured by the manufacturing method according to the embodiment is shown. This V-belt B is used as a power transmission member of various equipment. The belt length of the V-ribbed belt B is, for example, 700 to 3000 mm, the belt width is, for example, 10 to 36 mm, and the belt thickness is, for example, 4.0 to 5.0 mm.

[0057] The V-ribbed belt B of the embodiment includes a rubber belt main body 10 including a central rubber layer 111 located on the inner peripheral side in the thickness direction and an adhesive rubber layer 12 located on the outer peripheral side in the thickness direction. The surface of the central rubber layer 111 is covered by the surface rubber layer 112, and the compression rubber layer 11 is formed by the above-mentioned central rubber layer 111 and the surface rubber layer 112, and the compression rubber layer 11 is...

Abstract

Provided is a method for producing a V-ribbed belt having a plurality of V-shaped ribs extending in a longitudinal direction and arranged in a width direction. The method includes: setting a shaped structure having a plurality of ridges arranged adjacent to one another in a belt mold including a plurality of compressed rubber layer-shaping grooves arranged adjacent to one another on an inner peripheral surface of the mold; molding a belt slab by crosslinking the shaped structure set in the mold, while compressed rubber layer-forming portions face radially outward and are fitted in the compressed rubber layer-shaping grooves, the compressed rubber layer-forming portions comprised of a surface rubber layer and a core rubber layer which are to constitute surface and inner portions, respectively; and cutting the belt slab into ring-shaped pieces having two or more of the compressed rubber layer-forming portions.

Description

technical field [0001] The invention relates to a method for manufacturing a V-ribbed belt. Background technique [0002] When extruding an uncrosslinked rubber composition mixed with short fibers, the orientation of the short fibers is not uniform enough, so even if the obtained uncrosslinked rubber sheet is used, it is difficult to manufacture low-cost, low-friction noise, and wear-resistant Excellent V-belt. Therefore, an uncrosslinked rubber sheet for forming a V-shaped wedge in which short fibers are oriented in the width direction is actually produced by kneading an uncrosslinked rubber composition mixed with short fibers, and then Calendering with a calender to form an uncrosslinked rubber sheet in which short fibers are oriented in the length direction, and then cutting the uncrosslinked rubber sheet at a fixed length in a direction perpendicular to the length direction to form rubber cut sheets, these rubbers are cut The sides of the sheet were joined to each othe...
