Problems solved by technology
Since the upper gear and the drive shaft are tightly locked by four adjusting screws, the fastening force is relatively poor, and the upper gear may move axially or radially with the high-speed rotation of the drive shaft, causing the upper gear to move , which in turn causes the big tripod gear angle of the large circular knitting machine to change, and the positions of the upper dial and the lower dial to change, making the knitting needles disordered
[0004] In addition, since the synchronous wheel is directly assembled on the lower end of the transmission shaft, under the action of the synchronous belt, the transmission shaft has a large radial tension and is prone to deformation

Embodiment Construction
[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0035] Such as figure 1 As shown, the main transmission structure of the circular knitting machine provided in this embodiment includes a vertically arranged transmission shaft 1, and the specific installation position of the transmission shaft 1 is the same as that of a conventional large circular knitting machine. The transmission shaft 1 is installed with the upper gear 2, the first bearing seat 3, the lower gear 4, the second bearing seat 5 and the synchronous wheel 6 in order from top to bottom, wherein the first bearing seat 3 and the second bearing seat 5 are fixed on the large knitting circle On the frame of the knitting machine, it is used to form a support for the transmission shaft 6. The gear parameters of the upper gear 2 and the lower gear 4 and the functions they play are the same as those of a conventional large circular knittin...

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.
Description
technical field [0001] The invention relates to a transmission structure of a circular knitting machine, in particular to a main transmission structure of a large circular knitting machine. Background technique [0002] A common textile equipment on a large circular knitting machine. The transmission device of a large circular knitting machine generally includes a main transmission unit connected to the motor transmission and an auxiliary transmission unit connected to the main transmission unit. The transmission shaft of the main transmission unit is installed with An upper gear positioned at the upper end of the transmission shaft, a lower gear positioned at the body of the transmission shaft, a synchronous wheel positioned at the lower end of the transmission shaft, and two upper and lower bearing seats for supporting the transmission shaft. [0003] In order to adjust the relative position between the upper needle plate and the lower needle cylinder of the large circular...
