Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
With reference to shown in Fig. 3, a kind of rotational structure of big disc gear, in circular knitting machine, comprises deep bid 1, big disc gear 2 and rotary part 3, and rotary part 3 is made up of outer ring 4, inner ring 5 and the rolling element 6 be arranged between inner ring 4 and outer ring 5.Outer ring 4 is fixed on big disc gear 2 by securing member, inner ring 5 is fixed on deep bid 1 by securing member, rolling element 6 is made up of numerous ball or roller, between rolling element 6, be also provided with retainer 9, to reduce phase mutual friction between rolling element 6, improve its service life, rolling element 6 can be single, also can be many rows, arrangement mode has multiple, and the rolling element 6 in the present invention is 3 rows.
Because rolling element 6 directly controls axial, the circular runout of outer ring 4 and inner ring 5 in raceway, and the active force that can bear from all directions, big disc gear 2 is all rigidly connected again with inner ring 5 with outer ring 4, deep bid 1, so Stability Analysis of Structures, during machine run, rotating speed can be greatly improved, and (actual to use, because other annex is as the restriction of knitting needle, triangle, Thread-feeding device etc., rotating speed is at about 40 revs/min, later along with the raising of annex quality, rotating speed is expected to further raising).
With reference to shown in Fig. 4-6, other arrangement mode of raceway in rotary part 3.Can to roll in raceway rotation in various arrangement mode by single row or multiple rows rolling element 6 between inner ring 5 and outer ring 4;
Wherein Fig. 4 is single row configuration, rolling element is the rotary part of ball, and it is provided with a raceway between inner ring 5 and outer ring 4, and single rolling element 6 is arranged in this raceway; Fig. 5 is two-row structure, rolling element is the rotary part of ball, and it is provided with two raceways between inner ring 5 and outer ring 4, and the rolling element 6 of two rows is separately positioned in raceway; Fig. 6 is single row configuration, rolling element is the rotary part of roller, and it is provided with a raceway between inner ring 5 and outer ring 4, raceway inclination certain angle, and single rolling element 6 is arranged in a crossed manner in raceway respectively, stable operation.
Larger cavity 7 can also be provided with in deep bid 1, it is rotary part lubricating oil storage chamber when cavity 7 is flat, entering if any foreign matter wherein also has sufficient space to hold, again because rotary part 3 is semi-closed structures, rolling element 6 is away from bottom, so foreign matter cannot enter, it is inner, thus also has no way of affecting the precision of rotary part 3.With reference to shown in Fig. 3, be provided with larger cavity 7 in deep bid 1, rotary part 3 is arranged in this cavity 7.
With reference to shown in Fig. 3, between outer ring 4 and inner ring 5, between big disc gear 2 and deep bid 1, also arrange sealing ring 8, sealing ring 8 is lip-type packing, has effectively completely cut off rotary part lubricating oil and has revealed from deep bid 1 inner ring, preventing pollution cloth and environment.The pad that thickness is 0.01mm-0.2mm is also provided with, in order to adjustment and recovery precision between rotary part 3.
The rotational structure of big disc gear of the present invention is used in circular knitting machine, and the existing mill model comparison in market, actually uses rotating ratio it doubles and has a surplus, and the corresponding cloth daily output also doubles has a surplus.Under the prerequisite of producing identical output, the present invention at least saves the production cost (production cost comprises: energy consumption, artificial, place etc.) of half than the existing type in market.
Stability Analysis of Structures of the present invention, rotating speed is fast, improves the daily output of cloth; Sound construction, can long time running, decreases maintenance shut-downs cost; Cavity body structure on deep bid can store foreign matter, and prevents foreign matter to the infringement of rotary part, and then extends service life and the running precision of machine; The pollution of lubricating oil to cloth and environment stopped by hermetically-sealed construction.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
