Abstract
Disclosed is a transmission gear fine adjustment and fixation mechanism used for weaving machine, comprising a transmission gear and a transmission shaft. The transmission gear is provided with a base, wherein the central section of the base which is around the axis of the base is provided with a semicircular concave part which passes through the through hole part of the base. An embedding body which can be embedded with the concave part is arranged in the concave part. The through hole part of the transmission gear passes through the sleeve part of the transmission shaft. The base and the concave part of the transmission shaft are aligned to form a through channel. The embedding block is embedded in the through channel. The embedding block which is corresponding to the locating hole of the transmission shaft is located on the transmission shaft by the locating device. A screw passes through the base to be forced compactly to the embedding block. The embedding body is embedded in the semicircular concave part of the base. The embedding body and the base are screwed by the bolt. Therefore, the embedding body can generate constrictive effect on the transmission gear and the transmission shaft, which can make the transmission gear not easy to loosen. The operation mode is simple and quick.
