Abstract (en)
[origin: WO2010052213A1] Friction discs made from a hard material such as ceramic or metal as a rule generate wear and thus damage the threads more than, for example, soft friction discs made from polyurethane which undergo wear by the threads. Whilst friction discs made of hard material can be used as a rule for more than seven years, friction discs made from polyurethane must be changed after just 8 to 9 months. According to the invention, friction discs (1) thus have at least one friction area reducing groove on the friction surface (4) thereof.
