Abstract

"GAIOLA DE ROLAMENTO DE ESFERAS DE CONTATO ANGULAR COM BOLSõES DE LUBRIFICANTE". A invenção refere-se a gaiola de janela (2) para um rolamento de esfera de contato angular, sendo que nas faces dos bolsões esféricas, previstas para a condução das esferas, estão integrados bolsões de lubrificante, sendo que estes bolsões de lubrificante (3a, 3b) estão previstos em uma região situada em direção circunferencial (6) e em direção axial fora dos pontos de encontro (7a, 7b, 8a, 8b) entre esfera o gaiola, sendo que a espessura da parede nos pontos de encontro (7a, 7b, 8a, 8b) não é enfraquecida pela posição e configuração dos bolsões de lubrificante.
