| 摘要 |
The invention relates to a mechanism for transformation of a rotary motion into a translatory motion or vice versa, consisting of a curve follower for co-operation with a rotary cylindrical curve body, in which is designed a curved guide in the shape of a wedge-shaped track in the body, and where the curve follower consists of an inwardly pointing similar wedge-shaped ring with a larger diameter than that of the curved body, and which is located excentrically in relation to the latter in such a manner, that the inner edge of the ring meshes with the track. The ring is the inner ring of a roller- or ball bearing or is incorporated with such an inner ring while the outer ring or parts connected therewith are retained against rotation in relation to the curved body or vice versa. |
