ROTATION/TRANSLATION CONVERTER GEAR UNIT |
| 摘要 |
A rotation/translation converter gear unit having a helical gear and a planetary gear for driving the helical gear. A spindle nut of the helical gear forms a planet carrier for planet wheels of the planetary gear. Situated between the planetary gear and the helical gear is an axial friction bearing, that at the same time forms a centering element which centers a sun wheel of the planetary gear between the planet wheels. In particular, the rotation/translation converter gear unit is used to drive a piston of a pressure generator for a brake control of a hydraulic vehicle brake system. |

1. A rotation/translation converter gear unit, comprising:
a planetary gear; a helical gear having a rotatable, axially fixed member having a thread, the rotatable member having a planet carrier having planet wheels of the planetary gear; an axially displaceable, rotatably fixed member having a mating thread, the mating thread configured to mesh with the thread of the rotatable member so that a rotational driving of the rotatable member axially displaces the axially displaceable member; and a centering device that centers a sun wheel of the planetary gear between the planet wheels. |
