Abstract:
1. A gear mechanism for driving a heald shaft, comprising: a hollow gear provided with an inside toothing; at least one planet gear provided with an outside toothing, which constantly meshes with the inside toothing of the hollow gear; a planet carrier on which the at least one planet gear is positioned such that the at least one planet gear can rotate; a sun gear provided with an outside toothing, which constantly meshes with the at least one planet gear; a drive assembly having an input shaft that is connected to at least one of the hollow gear, the planet carrier and the sun gear, for providing continuous different rotational speeds; and, an output shaft having an output end that is connected via a rod assembly with a heald shaft and an input end that is connected via a coupling mechanism to the at least one planet gear, which planet gear transmits a rotational movement from the input shaft of the drive assembly to the output shaft, and thereby superimposes an additional movement on the output shaft.
