BALL SCREW MECHANISM

The outer diameter f of a land section (1c) is set greater than BCD. As a result, the land section (1c) guides balls (3) when they enter a deep portion (portion near the axis (O) of a screw shaft (1)) of a circulation path (1b). This makes the circulation of the balls (3) smooth. Dans cette inventio...

Beschreibung
Zusammenfassung:	The outer diameter f of a land section (1c) is set greater than BCD. As a result, the land section (1c) guides balls (3) when they enter a deep portion (portion near the axis (O) of a screw shaft (1)) of a circulation path (1b). This makes the circulation of the balls (3) smooth. Dans cette invention, le diamètre extérieur f d'une section plate (1c) est réglé pour être supérieur à BCD. Par conséquent, la section plate (1c) guide les rotules (3) lorsqu'elles entrent dans une partie profonde (partie à proximité de l'axe (O) d'un arbre de vis (1)) d'une voie de circulation (1b). Cela permet une circulation sans à-coups des rotules (3).
