Abstract: A gear driven by wobble movement contains an ergonomic pendulum (D), a centric disk (C) and a flywheel (A) having a common axis (S) of rotation. In the axis (S) of rotation a shaft (H) is placed which is joined to the pendulum (D). The mutual concentric position of the centric disk (C) and the flywheel (A) is delimitated by planet disk (B) which contacts the periphery of the centric disk (C) and the internal periphery of the flywheel (A) and is joined rotatably to the supporting structure (T). The supporting structure (T) is fixed to the linked structure which fixes the supporting structure (T), together with the planet disk (B), against rotation with respect to the axis (S) of rotation. A first freewheel (V1) is situated between the shaft (H) and flywheel (A) and a second freewheel (V2) is situated between the shaft (H) and centric disc (C).

Abstract: The gear driven by wobble movement contains an ergonomic pendulum (D), a centric disk (C) and a flywheel (A) which have a common axis (S) of rotation. In the axis (S) of rotation a shaft (H) is placed which is rigidly joined to the pendulum (D). The mutual concentric position of the centric disk (C) and the flywheel (A) is delimitated by one planet disk (B) at least which contacts the outer periphery of the centric disk (C) and the internal periphery of the flywheel (A) and is joined rotatably to the supporting structure (T). The supporting structure (T) is fixed to the linked structure which fixes the supporting structure (T), together with the planet disk (B), against rotation with respect to the axis (S) of rotation. Between the shaft (H) and the flywheel (A) a first freewheel (VI) is situated while between the shaft (H) and the centric disk (C) a second freewheel (V2) is situated. The senses of rotation of the freewheels (VI and V2) are different.

Abstract: A method of production of high-strength hollow bodies from multiphase martensitic steels includes a heating process, a forming process and a cooling process. A heating device heats hollow steel stock to the austenitic temperature of the material from which the stock is made. The stock is then converted by deformation in a forming device into a hollow body having the final shape. A cooling device thereafter cools the hollow body such that the material with the original austenite microstructure refined by deformation during the forming process cools to a temperature at which incomplete transformation of austenite to martensite occurs. The retained austenite stabilization is performed in an annealing device by diffusion-based carbon partitioning within the material from which the hollow body is made. The hollow body is cooled in a cooling device to ambient temperature after stabilization.
