In order to achieve the above object, technological scheme of the present invention is:
A kind of bent axle that is used for the high speed warp knitting machine, bent axle body are provided with axle head, axle journal, eccentric part, balance portion, oil circuit; Bent axle body two ends have axle head and axle journal respectively, 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 the 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 also is drilled with radial hole with eccentric part, and outlet links to each other with asphalt channel as oil circuit, and the oil circuit that forms the bent axle body provides lubricated to kinematic pair.
Described balance portion is cylindric, and its mounted on surface has balancing weight.
Described eccentric part comprises first eccentric part that is connected with groove pin sley bar oscillator device, 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 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 be 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 first eccentric part, second eccentric part, in the 3rd eccentric part any two.
Described bent axle body can form 3～20 combine and assemble on a warp knitting machine equipment, the axle head of bent axle body is connected with adjacent bent axle body or machine spindle through 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, and is spatially compact more.Transmission is steady more, accurate, and noise is little during high speed, and it is more reasonable that lopping cooperates, and therefore be fit to high-speed motion mechanism more, and manufacturing efficiency significantly improves.The present invention has guaranteed the active force of loop-forming element gentle through adopting the bent axle of optimizing the design of lopping Motion curves.This measure through brand-new design is theoretical correct, implements effectively simple.Through 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 the warp knitting machine operation more steadily, reliable, noise is low, less energy consumption.
