Abstract

PORTA-ESFERAS DE ROLAMENTO E ROLAMENTO DE ESFERAS COM CONTATO OBLìQUO A presente invenção refere-se a um rolamento de esferas com contato oblíquo o qual compreende duas pistas de rolamento anulares entre as quais são dispostas esferas 24 cujos centros são distribuídos sobre um circulo primitivo do rolamento, e os pontos de contato das esferas com as duas pistas de rolamento são distribuídos sobre um cone de contato. Um porta-esferas mantém as esferas e compreende uma pluralidade de alvéolos 32 de alojamento das esferas. Cada alvéolo compreende duas paredes cóncavas opostas 36A, 36B em forma de calota esférica de raio R, e os centros 40A, 40B das duas calotas são dispostos em um mesmo plano radial à distância um do outro ao longo de um eixo 42 inclinado em relação ao eixo de rotação do rolamento. A forma oblonga dos alvéolos permite reduzir os atritos entre eles e as esferas.
