Abstract

Reversible Rotary to Linear Motion Converting Device A reversible rotary to linear motion converting device which in one form comprises a screw member having multiple-lead threads, a plurality of roller members equal in number to the number of thread starts on the screw member with each of the roller members having a plurality of annular teeth of substantially equal axial pitch to the teeth on the screw member and a matching configuration to the shape of the teeth of the screw member, and an annular nut member. The roller members are mounted in rolling contact with the threads of the screw member and the annular nut member is mounted about the roller members in rolling contact therewith. The annular nut member has a plurality of internal annular grooves of substantially equal pitch and complementary shape to the annular teeth of the roller members. The nut member has substantially as many grooves as the number of teeth on each of the roller members so that when any rotational force is applied to the screw member with the nut member constrained against rotation, the total action and reaction forces on each of the roller members are substantially equal and opposite. In a further form of the invention, the multiple-lead threads are formed as internal threads in the annular nut member and the central screw member is provided with the annular teeth matching the annular teeth of the roller members.
