Problems solved by technology

In combination with the use of special synthetic elastomers for increased temperature resistance there is the disadvantage that defined mechanical properties cannot be optimized simultaneously with the temperature resistance
These special synthetic elastomers are also usually more expensive to manufacture

Embodiment Construction

[0037] figure 1 a shows a schematic view of a belt cross section through a force transmission belt 1 in the form of a wedge-shaped ribbed belt 1 here with six ribs 2 . The elastomer base 3 comprises the ribs 2 formed from a uniform elastomer material as well as the entire substructure and the belt back 4 . Only the outermost layer 5 of the belt back 4 contains flake-shaped metal particles, here aluminum flakes, mixed into the elastomer ("flake aluminum powder", manufacturer: Eckart Effect Pigments, Germany) , the aluminum flakes have (97-100%) 71 micron sieve openings and a particle size distribution with a D50 of approximately 47 microns. The layer thickness of the layer 5 is 1 mm. By calendering, the aluminum fragments are not completely disordered, but are oriented longitudinally relative to the layer by a statistically significant amount.

Abstract

The use of metal particles inside the belt back (4) of a force transmission belt (1) serves primarily to protect the belt from overheating in transient temperatures of between 100°C and approximately 400°C which can occur during operation in motor vehicle engine compartments and in the heat radiation region of exhaust systems. To this end, the force transmission belt (1), which has a main body (3) made of at least one elastomeric material and having a sub-structure and a belt back (4), and a force transmission zone on the sub-structure, has lamella-type or flake-type particles made of metal, particularly aluminium, mixed into the elastomer at least in an outermost layer (5) of the belt back (4).

Description

technical field [0001] The invention relates to a force transmission belt having a base body made of at least one elastomer material, the base body having a lower structure and a belt back, wherein a force transmission zone is formed on the lower structure. Background technique [0002] The invention relates to the field of power transmission belts for traction means drives. These can be flat belts, wedge belts, wedge ribbed belts, toothed belts. Belts for traction means transmissions are generally subject to special dynamic mechanical requirements. Due to internal shear forces, the belt undergoes a slight self-heating during operation, which can however be well controlled with modern elastomer belts. Belts of the type referred to here are usually employed in high power machines or motors. Especially in vehicle motors used in land vehicles, water vehicles and air vehicles, these belts can be exposed to external thermal loads, which are caused by the high operating tempera...
