Abstract:
(EN) An elevator brake has a friction part. The friction part is made of fine ceramics. In addition, the friction part contacts a guide rail that guides the lifting or lowering of a body being lifted or lowered and brakes the body being lifted or lowered by way of frictional force with the guide rail. The friction part is provided with a plurality of cone-shaped projections. Each projection has a vertex that contacts the guide rail during braking of the body being lifted or lowered with the friction part.
(FR) L’invention concerne un frein d'ascenseur comportant une partie de frottement. La partie de frottement est constituée de céramiques fines. De plus, la partie de frottement entre en contact avec un rail de guidage qui guide le levage ou l'abaissement d'un corps qui est levé ou abaissé et freine le corps qui est levé ou abaissé au moyen d'une force de frottement avec le rail de guidage. La partie de frottement est dotée d'une pluralité de saillies coniques. Chaque saillie a un sommet qui entre en contact avec le rail de guidage pendant le freinage du corps qui est levé ou abaissé à l’aide de la partie de frottement.
(JA) エレベータの制動子は、摩擦片を有している。摩擦片は、ファインセラミックスにより構成されている。また、摩擦片は、昇降体の昇降を案内するガイドレールに接して、ガイドレールとの間の摩擦力によって昇降体を制動する。摩擦片には、複数の錐体形の突起が設けられている。各突起は、摩擦片による昇降体の制動時にガイドレールに接する頂点を有している。
