Abstract

The utility model discloses a big disk gear device for a big circular knitting machine. The big disk gear device for the big circular knitting machine comprises a big disk gear and a big disk used for supporting the big disk gear. A supporting structure is arranged between the big disk gear and the big disk, and a gap is formed between the big disk gear and the big gear. The supporting structure comprises a supporting seat, circular arc notches are formed in the upper end and the lower end of the supporting seat, friction balls matched with the circular arc notches are arranged in the circular arc notches in the upper end and the lower end, and the big disk gear and the big disk are respectively provided with a friction groove. According to the big disk gear device for the big circular knitting machine, the friction balls on the supporting seat are used for forming rolling friction with the big disk gear and the big gear respectively, the friction force among the big disk gear, the big disk and a friction plate is reduced, energy loss is lowered, meanwhile, the gap between the big disk gear and the big gear can be prevented from being enlarged, friction is further reduced, the positioning precision is improved, and the service life is prolonged.

Description

For the big disc gear device on big round needle loom

Technical field

The utility model relates to a kind of big round needle loom, relates in particular to a kind of for the big disc gear device on big round needle loom.

Background technology

A few days ago, existing most of big round needle looms are that the moving syringe mode of gear wheel dribbling is carried out knitting action, therefore whether just circle rotation of wheel disc, and direct relation the vertical quality of pin.

And wear plate is set as supporting role between gear wheel and deep bid, and completing relatively rotating of gear wheel by sliding friction, this structure is left following several defect:

1, because wear plate belongs to fixing state at gear wheel and deep bid, make it have larger frictional force, cause the loss of energy;

2, the fricative powder of gear wheel, deep bid and wear plate stains gear oil, causes wearing and tearing to strengthen, and makes gap between gear wheel and deep bid become large, and circumferential registration precision reduces.

Utility model content

In order to overcome above shortcomings part in prior art, it is a kind of for the big disc gear device on big round needle loom that the purpose of this utility model is to provide, and it reduces frictional force, reduces the energy consumption of machine, improves maintainability.

In order to reach above-mentioned object, the utility model adopts following concrete technical scheme:

For the big disc gear device on big round needle loom, comprise big disc gear and for supporting the deep bid of this big disc gear, between described big disc gear and deep bid, be provided with supporting construction, make to form gap between big disc gear and deep bid, make to form gap between big disc gear and deep bid, described supporting construction comprises supporting seat, and the upper and lower side of described supporting seat is provided with arc gap, and the arc gap of described upper and lower side is provided with the friction ball mating with it.

Further, big disc gear described in the utility model and deep bid are equipped with frictional groove.

The utility model advantage is compared with prior art: the utility model forms rolling friction with big disc gear, deep bid respectively by the friction ball on supporting seat, reduce the frictional force between big disc gear, deep bid and friction plate, reduce energy loss, be both gap between minimizing big disc gear and deep bid and become large, further reduce friction, improve positioning precision, increase the service life.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the I-I enlarged drawing of Fig. 1;

Below in conjunction with accompanying drawing, the utility model is described in further detail.

The specific embodiment

In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.

Embodiment:

With reference to Fig. 1, shown in Fig. 2, for the big disc gear device on big round needle loom, comprise big disc gear 1 and for supporting the deep bid 2 of this big disc gear, between described big disc gear 1 and deep bid 2, be provided with supporting construction, make to form gap 3 between big disc gear 1 and deep bid 2, gap 3 coordinates for discontiguous free state work, described supporting construction comprises supporting seat 4, the upper and lower side of described supporting seat 4 is provided with arc gap 5, the arc gap 5 of described upper and lower side is provided with the friction ball 6 mating with it, simultaneously big disc gear 1 below with above deep bid 2, be respectively provided with frictional groove 7, make friction ball 6 be separately positioned on the arc gap of upper and lower side and above deep bid, between below big disc gear, form rolling friction, reduce big disc gear 1, frictional force between deep bid 2 and friction plate, reduce energy loss, be both gap between minimizing big disc gear and deep bid and become large, further reduce friction, improve positioning precision, increase the service life.

But the above-mentioned specific embodiment is exemplary, be to be the restriction that this patent is comprised to scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; As long as any being equal to done according to spirit that this patent discloses changes or modify, all fall into the scope that this patent comprises.
