Described balance section is cylindric, and its surface is equipped with balancing weight.
Described eccentric part comprises the first eccentric part that is connected with groove pin sley bar oscillator device, the second eccentric part that is connected with the nook closing member oscillator device, with the 3rd eccentric part that is connected the sinker oscillator device; The center of the first eccentric part and bent axle body center are at the zero degree of same level as bent axle, then the second eccentric part center and bent axle body center angle are θ 1, the excursion of θ 1 is ［ 0, π], the 3rd eccentric part center and bent axle body center angle are θ 2, the excursion of θ 2 be 0,2 π].
Described eccentric part is two, is the first eccentric part, the second eccentric part, in the 3rd eccentric part any two.
Described bent axle body can form 3～20 combination assemblings at a warp knitting machine equipment, the axle head of bent axle body by key and shaft joint be connected bent axle body or machine spindle and connect.
Compared with prior art, the utility model has reduced the number of components that four bar warp knitting machines become transmission gear of circle, and is spatially compact.Transmission is more steady, accurate, and noise is little during high speed, and it is more reasonable that lopping cooperates, and therefore more be fit to mechanism with high speed motion, and manufacturing efficiency significantly improves.The utility model has guaranteed the active force of loop-forming element gentle by adopting the bent axle of optimizing the design of lopping Motion curves.This measure through brand-new design is theoretical correct, implements effectively simple.By utilizing crankshaft arrangement of the present utility model, make the cooperation of loop-forming element of machine more accurate, machine speed is faster, knitting property is reliable and stable, thereby so that the warp knitting machine operation more steadily, reliable, noise is low, less energy consumption.
