| 摘要 |
The invention relates to a planetary gear having two adjacent identical central wheels of different pitch and a planet wheel whose pitch is equal to that of a virtual tooth row formed by the central wheel teeth. The teeth of the planet wheel extend into the tooth gaps between the virtual tooth rows. The planet wheel is guided and driven by a rotary disk. At least two of the three wheels have pivotable teeth. The teeth of both the central wheels and the planet wheel are of substantially triangular cross section with plane tooth profiles. It is a main objective of the invention to provide a planetary gear permitting the flank angles of the virtual tooth gaps to be adapted to the profile angle of the planet wheel teeth, in particular, in order to transmit large torques and/or also in order to achieve low speed ratios. According to the invention, the pivotable teeth of at least one central wheel are arranged on journals.
