Abstract
The invention provides a main transmission structure of a circular knitting machine. The main transmission structure comprises a transmission shaft arranged vertically, an upper gear, a first bearing pedestal, a lower gear, a second bearing pedestal and a synchronizing wheel are sequentially arranged on the transmission shaft from top to bottom; an upper thread section is arranged at the upper end of the transmission shaft, a taper section is arranged at the position, close to the upper thread section, of the transmission shaft, the upper gear is installed on the taper section, a taper hole matched with the taper section is formed in the upper gear, and an upper nut used for fixing the upper gear is spirally matched with the upper thread section. Due to the facts that the taper section is arranged on the transmission shaft, and the taper hole is formed in the upper gear, taper fit is formed between the transmission shaft and the upper gear, acting force exerted on the upper gear is converted into axial force and radial force exerted on the transmission shaft, axial or radial play of the upper gear is avoided, the upper gear is not prone to shifting, it is ensured that position of an upper dial and the position of a lower dial are stable relatively, and therefore knitting needle sorting is not prone to disorder.
