Abstract
1326588 Screw-and-nut mechanism TOYODA KOKI KK 7 Dec 1970 [13 Dec 1969] 57940/70 Heading F2Q In a recirculating ball screw-and-nut mechanism, at least one of the ball-engaging profiles perpendicular to the lead of the helical grooves is formed by a first profile portion of a concave short arc 22, Fig. 3, to contact with balls 14 and a second profile portion 26 which connects with the end of the arc 22 and recedes from the centre of the ball and extends beyond a tangential line 24 drawn at the end of the arc 22. A similar second profile portion 25 is provided at the opposite end of the arc 22. Opposite flanks have similar profiles comprising short arcs 32 and second profile portions 35, 36. In a modification, shown in Fig. 6, opposite flanks have first profile portions 22b, 32b and straight line second profile portions 25b, 26b. A ball return tube 15 is provided.
