Abstract

ROLETE DE ESTEIRA COM RIGIDEZ REDUZIDA. Um rolete de esteira (300) inclui um corpo (302) com uma configuração anular definindo um eixo de rotação (304), uma direção radial (308) e uma direção circunferencial (306) dispostos em torno do eixo de rotação (304). O corpo (302) também define um orifício de passagem (316) que se estende axialmente através do corpo (302) centralizado no eixo de rotação (304). Um vazio cego (318) está disposto anularmente em torno do eixo de rotação (304), o vazio cego (318) sendo espaçado radialmente afastado do orifício de passagem (316) por uma distância mínima predeterminada (332), formando uma porção cantiléver (320) definindo um ponto flexível (326) e uma distância radial flexível (328) medida radialmente a partir do ponto flexível (326) até o orifício de passagem (316).
