FIELD: machine building. ^ SUBSTANCE: invention refers to machine building, particularly, to mechanisms of conversion of rotary motion into progressive one. The device for motion conversion consists of a screw and a nut having the same profile and a thread pitch, but different sizes of diameter. Bearing axles with convexo-convex rotation disks mounted on them are arranged between the screw and the nut parallel to axis of the device. On one end the bearing axles have one-sided flanges secured in slots of the internal side of one of the end covers; another end of the bearing axles is flat and stabilised with an internal response slot of another end cover. The end covers are connected with the nut with fasts. Amount of the bearing axles with convexo-convex disks of rotation is determined from the condition of their adjacency. ^ EFFECT: increased resource of operation and reliability of mechanism at low friction conditioned losses. ^ 2 cl, 9 dwg |
