The specific embodiment
To carry out clear, intactly description to the technical scheme in the embodiment of the invention below, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
With reference to shown in Figure 3, a kind of rotational structure of deep bid gear is used for circular knitting machine, comprises deep bid 1, deep bid gear 2 and rotary part 3, rotary part 3 by outer ring 4, inner ring 5 and be arranged on inner ring 4 and outer ring 5 between rolling element 6 form.Outer ring 4 is fixed on the deep bid gear 2 through securing member, and inner ring 5 is fixed on the deep bid 1 through securing member, and rolling element 6 is made up of numerous balls or roller; Between rolling element 6, also be provided with retainer 9,, improve its service life to reduce phase mutual friction between the rolling element 6; Rolling element 6 can be for single; Also can be many rows, arrangement mode has multiple, and the rolling element 6 among the present invention is 3 rows.
Because of rolling element 6 has directly been controlled axial, the circular runout of outer ring 4 with inner ring 5 in raceway, and can bear the active force from all directions, deep bid gear 2 all is 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 (in actual the use, because of other annex like the restriction of knitting needle, triangle, Thread-feeding device etc., rotating speed is about 40 rev/mins; Along with the raising of annex quality, rotating speed is expected to further raising later on).
Shown in Fig. 4-6, other arrangement mode of raceway in the rotary part 3.Lean on the single row or multiple rows rolling element 6 can be between inner ring 5 and the outer ring 4 with the rotation of in raceway, rolling of multiple arrangement mode;
Wherein Fig. 4 is that single row configuration, rolling element are 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 that two-row structure, rolling element are the rotary part of ball, and it is provided with two raceways between inner ring 5 and outer ring 4, and two rows' rolling element 6 is separately positioned in the raceway; Fig. 6 is that single row configuration, rolling element are 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 respectively in raceway, stable operation.
Can also be provided with bigger cavity 7 in the deep bid 1; Cavity 7 is a rotary part lubricating oil storage chamber when flat; Wherein also have enough spaces to hold if any the foreign matter entering, again because of rotary part 3 is semi-closed structures, rolling element 6 is far away from the bottom; So foreign matter can't get into its inside, thereby also have no way of influencing the precision of rotary part 3.With reference to shown in Figure 3, be provided with bigger cavity 7 in the deep bid 1, rotary part 3 is arranged in this cavity 7.
With reference to shown in Figure 3, between outer ring 4 and the inner ring 5, between deep bid gear 2 and the deep bid 1 sealing ring 8 is set also, sealing ring 8 is lip-type packing, has effectively completely cut off rotary part lubricating oil from the leakage of deep bid 1 inner ring, prevents to pollute cloth and environment.Between rotary part 3, also be provided with the pad that thickness is 0.01mm-0.2mm, recover precision in order to adjustment.
The rotational structure of deep bid gear of the present invention is used for the existing type in circular knitting machine and market relatively, 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 practices thrift half the production cost (production cost comprises: energy consumption, manual work, place etc.) at least than the existing type in market.
Stability Analysis of Structures of the present invention, rotating speed is fast, has improved the daily output of cloth; Sound construction can turn round for a long time, has reduced the shutdown maintenance cost; Cavity body structure on the deep bid can store foreign matter, and prevents the infringement of foreign matter to rotary part, and then prolongs the service life and the running precision of machine; Hermetically-sealed construction has been stopped the pollution of lubricating oil to cloth and environment.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
