Publication number: 20220349455Abstract: A friction transmission belt includes a belt body which transmits power to a pulley. In a relationship between a friction coefficient and a slipping speed which is a difference between a speed of the belt body and a speed of the pulley, when a slipping speed at which a maximum friction coefficient is indicated is defined as a first slipping speed, a friction coefficient when the slipping speed is increased from the first slipping speed to a second slipping speed is defined as a reference friction coefficient, and a difference between the second slipping speed and the first slipping speed is 500 mm/s, a decrease rate Dm of the friction coefficient indicated by the following equation (1) with the maximum friction coefficient being denoted by ?x and the reference friction coefficient being denoted by ?r is not greater than 20%.Type: ApplicationFiled: April 11, 2022Publication date: November 3, 2022Applicant: BANDO CHEMICAL INDUSTRIES, LTD.Inventors: Yuya SHINDO, Shogo KOBAYASHI

Patent number: 10968979Abstract: A power transmission belt includes: a belt body and a cover fabric made of a fabric containing synthetic fibers as a main component and covering a surface of the belt body toward a pulley contact surface. The cover fabric has a surface toward the belt body, and the surface is in contact with a rubber composition containing cellulose-based short fibers. The rubber composition includes a rubber component in which the cellulose-based short fibers are dispersed. The cover fabric and the rubber composition containing the cellulose-based short fibers are exposed on a pulley contact surface.Type: GrantFiled: April 1, 2020Date of Patent: April 6, 2021Assignee: BANDO CHEMICAL INDUSTRIES, LTD.Inventor: Yuya Shindo

Patent number: 10174808Abstract: A V-ribbed belt has a cord made of polyester-based fibers, the total fiber fineness of which is 2200 dtex or more and 5500 dtex or less. A fiber fineness of the cord per belt width corresponding to a single V-shaped rib ranges from 10000 dtex to 19000 dtex. A belt dry-heat shrinkage force per belt width corresponding to a single V-shaped rib is 44 N or more. The belt dry-heat shrinkage force is a load increase with respect to a belt length of 300 mm in 30 minutes after applying, in an atmosphere of 150° C., a load of 6N in the belt longitudinal direction and holding the belt.Type: GrantFiled: March 8, 2018Date of Patent: January 8, 2019Assignee: Bando Chemical Industries, Ltd.Inventor: Yuya Shindo
