摘要： PROBLEM TO BE SOLVED: To provide a toothed belt with improved durability.
SOLUTION: The toothed belt 10 has a belt body 11 formed of an elastomer. The belt body 11 has a toothed rubber layer 12, to which a tooth part 20 is formed, and a rear rubber layer 22 provided to the rear face side of the belt. The surface of the toothed rubber layer 12 is covered with a tooth cloth 19. The tooth cloth 19 is woven with yarn extended in the longitudinal direction of the belt and yarn extended in the width direction. The yarn extended in the width direction includes polyarylate fiber yarn. The tooth cloth 19 is subjected to heat treatment after depositing a compound including rubber or latex on it before bonding it to the toothed rubber layer 12.

摘要： PROBLEM TO BE SOLVED: To improve the durability of belt while avoiding the generation of resonance phenomenon, and to lower the noise by forming the belt of the base material having uneven unit weight as a weight per unit length in the longitudinal direction along the longitudinal direction. SOLUTION: A power transmitting belt 20 is formed of a tooth surface part 23 having belt teeth 22 and a back surface part 26, and a core 24 formed of glass fiber or the like is embedded in the back surface part 26. The belt teeth 22 are respectively formed of a trapezoidal tooth, and a tooth cloth 28 is affixed to a surface of the belt teeth 22. In the base material forming the tooth surface part 23 and the back surface part 26, weight per unit length in the belt longitudinal direction, namely, unit weight thereof is uneven along the belt longitudinal direction. Namely, this base material has a first and a second belt parts A1, A2 having the unit weight different from each other. Since the base material forming the back surface part 26 and the tooth surface part 23 has the uneven unit weight along the belt longitudinal direction, even in the case where the number of revolution of a driving pulley is lowered, generation of resonance phenomenon is prevented.

摘要： PROBLEM TO BE SOLVED: To prevent chipping of a belt tooth and to lengthen travelling longevity of the belt by reducing a load applied on the belt tooth in high speed travelling with a high load. SOLUTION: A belt tooth 14 is formed on one surface of a belt main body 12 of a toothed belt 10. First and second projections 16 are provided by avoiding a central part of a tooth bottom 15 on the tooth bottom 15 formed between two of these belt teeth adjacent to each other. A pulley 30 is formed along the shape of the toothed belt 10, and a recessed part 34 to be engaged with the projection 16 is provided on a tooth top part of a pulley tooth 35.

摘要： PROBLEM TO BE SOLVED: To effectively damp the vibration of a strip member in a drive transmitting device using the strip member and prevent the early wear of the strip member. SOLUTION: A timing belt 30 that is the strip member is wound on a crank pulley 22 and cam pulleys 2 and 26. This device comprises a tension regulation part 50 for energizing the timing belt 30 from the back 30b of the timing belt 30 to the inside to regulate the tension of the timing belt 30. The tension regulation part 50 is provided with a guide member 52 extending along the longitudinal direction of the timing belt 30, and the guide member 52 is energized by a spring member 57 in the direction of stretching the timing belt 30. A plurality of roller member 60 is rotatably provided on the guide member 52. Each roller member 60 is partially protruded from the side surface 52c of the guide member 52 to abut on the back 30b of the timing belt 30.

摘要： PROBLEM TO BE SOLVED: To improve durability of a belt and reduce occurrence of noise by the belt by preventing the occurrence of resonance phenomenon of a power transmission belt. SOLUTION: A power transmission belt 20 consists of first, second, and third belts. The back part 26 and the tooth flank part 23 of a first belt part A1 are formed of a first base material. The back face part 26 and the tooth flank part 23 of a second belt part A2 are formed of a second base material having weight per unit length in a belt longitudinal direction lower than that of the first base material. The back face part 26 and the tooth flank part 23 of a third belt part A3 are formed of the first and second base materials. A unit weight is rendered uneven along the peripheral direction of the power transmission belt 20 and resonance phenomenon is prevented from occurring.
