    Abstract: The present invention pertains to a toothed belt comprising a back portion in which a core wire extending in the belt circumferential direction is embedded, and a plurality of tooth portions formed on the inner circumferential surface of the back portion at intervals in the belt circumferential direction, and including a back rubber layer formed on the outer circumferential side of the belt relative to the core wire, and a first rubber layer and a second rubber layer that are formed on the inner circumferential side of the belt relative to the core wire. The back portion includes the back rubber layer. The elastic modulus of the first rubber layer is larger than the elastic modulus of the second rubber layer. The first rubber layer is formed from a first cross-linked rubber composition including a first rubber component and first short fibers, the proportion of the first short fibers is 5-60 parts by mass with respect to 100 parts by mass of the first rubber component. The first short fibers are aligned in the belt longitudinal direction along the contour of the tooth portions, and the tooth portions include the first rubber layer and the second rubber layer which is interposed between the first rubber layer and the core wire.

    Abstract: The invention relates to a method for producing drive belts (ZR) by moulding. A mould core (21) and an outer shell (22) of a mould (20) are provided for this purpose. The circumferential surface of the mould core (21) or the inner circumferential surface (26) of the outer shell (22) is provided with a geometry (24) which is to be replicated on the drive belt (ZR). A textile layer (G) is laid on the geometry. The mould core (21) is positioned in the outer shell (22), and therefore the mould core (21) and the outer shell (22) delimit a cavity (23) between them. It is optionally possible for a tension member (Z) to be arranged in the cavity (23) and for the cavity (23) to be sealed in relation to the surroundings, at least in the region of the geometry (24) which is to be replicated on the drive belt (ZR). The textile layer (G) is placed on the surfaces delimiting the geometry (24) and an elastomer base material is introduced into the cavity (23). The invention also relates to a drive belt.

    Abstract: Provided is a toothed belt that has satisfactory durability even under high-temperature and high-load conditions or within an oil or water environment. The toothed belt 10 comprises a belt body 13 including a tooth rubber portion 11 and a backing rubber portion 12. A surface of the tooth rubber portion 11 is covered with a facing fabric 20. The facing fabric 20 is subjected to RFL treatment, and has an outer surface 21 covered with a hardened material of a first epoxy resin. The softening point of the hardened material of the first epoxy resin is, for example, 110°C or higher. The epoxy equivalent of the first epoxy resin is, for example, 100 to 1500 g/eq. Alternatively, the facing fabric 20 is subjected to impregnation treatment with a treatment agent including a second epoxy resin, a hardener for hardening the second epoxy resin, and a rubber component.
