CROSS-ROLLER BEARING

PROBLEM TO BE SOLVED: To provide a cross-roller bearing with rollers placed through an inner ring, which inhibits the roller from being locked in a joint on the inner-ring raceway surface. SOLUTION: A roller insertion hole 7 is formed on the inner ring 2 of the cross-roller bearing 1, and joints 11,...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a cross-roller bearing with rollers placed through an inner ring, which inhibits the roller from being locked in a joint on the inner-ring raceway surface. SOLUTION: A roller insertion hole 7 is formed on the inner ring 2 of the cross-roller bearing 1, and joints 11, 12 are formed on the inner-ring raceway surface 22 between the raceway surface 81 on the plug side which blocks this and it. Since the raceway surface 81 on the plug side is shaped like a trapezoid, the joints 11, 12 are extended in the inclined direction at an angle of less than 90 degrees with respect to the width direction of the raceway surface 22. As compared with the case where the joints 11, 12 are extended in the direction orthogonal to the raceway surface 22, the roller lock phenomenon in which the round end surface of the roller 5 collides against the joints 11, 12 and is inhibited from rolling is suppressed.
