In order to achieve the above object, technological scheme of the present invention is:
For a bent axle for Warp Knitted Fabrics, on bent axle body, be provided with axle head, axle journal, eccentric part, balance portion, oil circuit; Bent axle body two ends have respectively axle head and axle journal, and bent axle body intermediate equilibria portion and eccentric part are alternately laid, and eccentric part is at least two.
The present invention can be further perfect:
Described axle journal cylindrical is φ 45～φ 65mm, and eccentric part cylindrical is φ 40～φ 60mm, and balance portion cylindrical is φ 60～φ 100mm.
The inside of described bent axle body is drilled with the axial hole of φ 3～φ 10mm as asphalt channel, and axle journal is also drilled with radial hole with eccentric part, and as oil circuit, outlet is connected with asphalt channel, and the oil circuit that forms bent axle body provides lubricated to kinematic pair.
Described balance portion is cylindric, and its surface is provided with balancing weight.
Described eccentric part comprises the first eccentric part being connected with groove pin sley bar oscillator device, the second eccentric part being connected with nook closing member oscillator device, with the 3rd eccentric part that is connected sinker oscillator device; The center of the first eccentric part and bent axle body center be the zero degree as bent axle in same level, 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 on a warp knitting machine equipment, and the axle head of bent axle body is connected with adjacent bent axle body or machine spindle by key and shaft joint.
Compared with prior art, the present invention has reduced the number of components that four bar warp knitting machines become transmission gear of circle, spatially compact.More steadily, accurately, during high speed, noise is little in transmission, and it is more reasonable that lopping coordinates, and be therefore more applicable to mechanism with high speed motion, and manufacturing efficiency significantly improves.The present invention optimizes the bent axle of lopping Motion curves design by employing, guaranteed the active force of loop-forming element gentle.This measure through brand-new design is theoretical correct, implements effectively simple.By utilizing crankshaft arrangement of the present invention, make the cooperation of loop-forming element of machine more accurate, machine speed is faster, knitting property is reliable and stable, thereby make warp knitting machine operation more steadily, reliable, noise is low, less energy consumption.

Embodiment
Embodiment one
For a bent axle for Warp Knitted Fabrics, as shown in Figure 1, the parts that are mainly concerned with comprise axle head 1, axle journal 2, the first eccentric part 3, the second eccentric part 4, the 3rd eccentric part 5, balance portion 6, asphalt channel 7 to bent axle body 9.
Bent axle body 9 is integral structures, and above-mentioned all parts is to be mainly by different outside dimensions, on bent axle body 9, to form each independent sector.First at the two ends of bent axle body 9, respectively there are axle head 1 and axle journal 2, and be provided with balance portion 6 and the first eccentric part 3, the second eccentric part 4, the 3rd eccentric part 5 at the intermediate portion of bent axle body 9, each eccentric part and balance portion alternative arrangement, therefore three eccentric parts are furnished with altogether four balances 6 in the present embodiment.
