Embodiment Construction

[0018] according to figure 1 The blank consists of a drive belt back 1, a tension carrier layer 2, a first fiber-free base film 3 and a second base film 4 in which short fibers, such as aramid fibers or similar fibers, are mixed.

[0019] Corresponding to the known forming methods for producing V-rib drive belts, during the forming and vulcanization process the drive belt is molded into the surface of a substantially smooth blank. The layer thickness of the "fibre-filled" second layer 4 is conditionally reduced by the forming process from the rib tip to the rib bottom in relation to the distance from the rib tip to the rib bottom, for example About 50%. Since the wear at the rib peaks is particularly severe when V-rib belts or simple V-belts are in operation, the maximum thickness of the fiber-filled layer 4 is preferably in the region of the rib tips.

[0020] as in figure 1 The thicknesses of the blanks, layers or films 3 and 4 shown in are different, the thickness of the...

Abstract

Power transmission belt comprises a belt back (1); a first, fiber-free section (3) of vulcanized elastomer vulcanized on the belt back; a load-carrying section (2) embedded between the belt back and the first section; and a second section (4) of vulcanized elastomer vulcanized on the first section. Fibers are mixed into the second section. - An INDEPENDENT CLAIM is also included for a method of producing a ribbed V-belt comprising producing a belt blank by sequentially disposing on one another a belt back, a load-carrying section, a first fiber-free main body layer, and a second fiber-filled main body layer; and impressing ribs into the belt blank using a molding process.

Description

technical field [0001] The invention relates to a power transmission belt or drive belt and a method for its manufacture, wherein the drive belt comprises a belt back, a matrix of vulcanized rubber or rubber-like material and a tension-bearing layer embedded between the belt back and the matrix. Background technique [0002] In order to optimize the performance of the belt, the fibers are usually mixed into the base rubber compound throughout the thickness of the belt rubber, although essentially only the motion-transmitting surface area needs to be filled with fiber. [0003] In order to reduce the amount of expensive fibers used in drive belts, many efforts have been made, among which DE 100 16 351 C1 discloses that only the surface or part of the surface of the drive belt and preferably only the surface part of the motion transmission have plantings made of short fibers. Fleece material, here preferably a large number of fibers are only partially embedded in the surface. ...
