Abstract

a presente invenção refere-se a uma polia (15) para um elevador (1). a polia (15) compreende um corpo de base (17) feito, por exemplo, de aço, e que tem uma superfície circunferencial simétrica à rotação (23). adicionalmente, um revestimento redutor de atrito (21) é aplicado à superfície circunferencial (23) do corpo de base (17). em virtude do revestimento redutor de atrito (21) e, opcionalmente, em virtude de nivelamento adicional da superfície circunferencial (17) do corpo de base (23) antes de depositar o revestimento (21), um atrito muito baixo entre uma superfície externa (39) da polia (15) e uma superfície de contato de um elemento de tração em suspensão pode ser obtido. assim, as características de orientação da polia (15) podem ser aprimoradas e/ou requisitos de alinhamento após instalação da polia (15) podem ser flexibilizados. de preferência, o revestimento (21) pode compreender carbono de tipo diamante (dlc) ou nitreto de cromo (crn), de modo que o revestimento (21) possa conferir características superiores de resistência ao desgaste, deslizamento, proteção contra corrosão e elétrica.
