Abstract
Official abstract text for this publication.
In a friction transmission belt including a rubber layer forming a pulley contact surface, the rubber layer includes a rubber composition containing polyolefin particles and an inorganic filler. In the rubber composition, a total content of the polyolefin particles and the inorganic filler with respect to 100 parts by mass of a rubber component is 85 parts by mass or more.
First claim
Opening claim text (preview).
What is claimed is: 1. A friction transmission belt comprising a rubber layer forming a pulley contact surface, wherein the rubber layer includes a rubber composition containing polyolefin particles, and an inorganic filler, the inorganic filler includes at least silica not receiving coupling treatment, in the rubber composition, a content of the polyolefin particles with respect to 100 parts by mass of a rubber component is 50 parts by mass or more and 100 parts by mass or less, in the rubber composition, a content of the inorganic filler with respect to 100 parts by mass of a rubber component is 35 parts by mass or more and 85 parts by mass or less, and an aspect ratio obtained by dividing maximum outer diameters of the polyolefin particles by minimum outer diameters the polyolefin particles is 2.00 or smaller. 2. The friction transmission belt of claim 1 , wherein in the rubber composition, the total content of the polyolefin particles and the inorganic filler with respect to 100 parts by mass of the rubber component is 95 parts by mass or more and 185 parts by mass or less. 3. The friction transmission belt of claim 1 , wherein in the rubber composition, the total content of the polyolefin particles and the inorganic filler with respect to 100 parts by mass of the rubber component is 105 parts by mass or more and 185 parts by mass or less. 4. The friction transmission belt of claim 1 , wherein the polyolefin particles are ultrahigh molecular weight polyethylene having a molecular weight of 500,000 or more. 5. The friction transmission belt of claim 1 , wherein the inorganic filler further includes at least one of, montmorillonite, clay, and calcium carbonate. 6. The friction transmission belt of claim 1 , wherein in the rubber composition, a content of the silica with respect to 100 parts by mass of the rubber component is 30 parts by mass or more and 85 parts by mass or less. 7. The friction transmission belt of claim 1 , wherein the rubber composition does not contain a coupling agent. 8. The friction transmission belt of claim 6 , wherein the inorganic filler includes at least Ca-montmorillonite. 9. The friction transmission belt of claim 2 , wherein the polyolefin particles are ultrahigh molecular weight polyethylene having a molecular weight of 500,000 or more. 10. The friction transmission belt of claim 3 , wherein the polyolefin particles are ultrahigh molecular weight polyethylene having a molecular weight of 500,000 or more.
