Abstract

The utility model discloses a needle cylinder rotation stabilizing device of a circular weaving machine and belongs to the technical field of structural improvements of needle cylinder rotating devices of circular weaving machines. The needle cylinder rotation stabilizing device comprises a base, a bearing A, a rotating seat and a driving wheel. The rotating seat is supported on the base through the bearing A. The driving wheel is arranged at the bottom end of the rotating seat. The outer wall of the rotating seat is sleeved with a bearing B which is located between the lower end face of the base and the upper end face of the driving wheel. Meanwhile, a screw tightly jacking an inner ring of the bearing B is arranged on the driving wheel. The needle cylinder rotation stabilizing device of the circular weaving machine enables the rotation stability of a needle cylinder device to be jointly supported by the bearing A and the bearing B. Due to the fact that the screw tightly jacks the inner ring of the bearing B, backlash between the bearing A and the bearing B can be eliminated, and the rotation stability can be greatly improved. Consequently, the driving wheel receives the radial force of a transmission device, so that the condition that inclined-shaped rotating weaving can not happen.

Description

A kind of circular loom syringe slow-roll stabilization device

Technical field

The utility model discloses a kind of circular loom syringe slow-roll stabilization device, belongs to the technical field of circular loom syringe tumbler architecture advances.

Background technology

Needle cylinder device in circular loom carries out normal knitting after being driven by tumbler.As shown in Figure 1, existing tumbler mainly is comprised of base 2', bearing 3', rotation seat 4', driving wheel 5', rotation seat 4' is supported on base 2' by bearing 3', and above (bearing 3' inner ring is fixed on base 2', outer ring is for support rotating seat 4'), driving wheel 5' is arranged on the bottom of rotation seat 4'.Needle cylinder device 1' is arranged on the upper end of rotation seat 4', and during work, driving wheel 5' first drives rotation seat 4', then drives needle cylinder device 1' work by rotation seat 4'.The rotational stability that can be learnt needle cylinder device 1' by above structure is supported by bearing 3' entirely, and when bearing 3' stability has determined braiding, needle cylinder device 1' stablizes and fabric quality.Only has a bearing 3' below needle cylinder device 1', because bearing 3' has certain play, so driving wheel 5' is being subject under the effect of transmission device radial load that skew shape rotation braiding as shown in Figure 2 can occur, rotate braiding under as Fig. 2 skew shape, fabric quality is just bad, the quality problems such as the meeting generation strain line that weaves loosens, tighten inconsistent, and between upper and lower line, distance is inhomogeneous, weaving thread is crooked.

The utility model content

The purpose of this utility model is to provide a kind of circular loom syringe slow-roll stabilization device of high stable performance.

For achieving the above object, the technical scheme that the utility model adopts is:

A kind of circular loom syringe slow-roll stabilization device, comprise base, bearing A, rotation seat, driving wheel, rotation seat is supported on base by bearing A, driving wheel is arranged on the bottom of rotation seat, be equipped with bearing B on the outer wall of described rotation seat, and bearing B, between the upper end of the lower surface of base and driving wheel, is equipped with the screw that holds out against bearing B inner ring on driving wheel simultaneously.

As the further setting of such scheme, described bearing B is with dust ring.

Described screw is provided with several, and circumferentially is evenly distributed on driving wheel.

A kind of circular loom syringe of the utility model slow-roll stabilization device, set up a bearing B between the upper end of the lower surface of base and driving wheel, and the inner ring of bearing B is held out against by the screw be arranged on driving wheel, make the rotational stability of needle cylinder device jointly be supported by bearing A and bearing B, because screw holds out against the inner ring of bearing B, eliminated bearing A, the play of bearing B, therefore driving wheel is being subject under the effect of transmission device radial load that the situation of skew shape rotation braiding as described in the background art can not occur, rotation braiding under skew shape is not occurring in needle cylinder device, so fabric quality is all right, can not produce woven strain line pine, tightly inconsistent, on, between rolling off the production line, distance is inhomogeneous, the quality problems such as weaving thread is crooked.

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

The accompanying drawing explanation

Fig. 1 is the structural representation of existing circular loom syringe tumbler;

Fig. 2 is the skew shape rotation woven condition schematic diagram that the driving wheel in Fig. 1 is being subject to occurring under the effect of transmission device radial load;

Fig. 3 is structural representation of the present utility model.

The specific embodiment

As shown in Figure 3, a kind of circular loom syringe slow-roll stabilization device, comprise base 2, bearing A3, rotation seat 7, driving wheel 6, and rotation seat 7 is supported on base 2 by bearing A3, and driving wheel 6 is arranged on the bottom of rotation seat 7, is more than prior art.Inventive point of the present utility model is: be equipped with bearing B5 on the outer wall of rotation seat 7, and bearing B5 is equipped with the screw 8 that holds out against bearing B5 inner ring 51 on driving wheel 6 between the upper end of the lower surface of base 2 and driving wheel 6 simultaneously.

In order to prevent that dust from entering bearing B5 inside, to reduce the wearing and tearing of bearing B5, improve service life, bearing B5 of the present utility model is with dust ring 4.Screw 8 in the present embodiment holds out against dust ring 4, bearing B5 inner ring 51 from bottom to top successively.

In order further to improve stability, the screw 8 in the utility model is provided with several, and circumferentially is evenly distributed on driving wheel 6.

The operation principle of a kind of circular loom syringe of the utility model slow-roll stabilization device is as follows:

The needle cylinder device 1 that drives rotation seat 7 in the time of driving wheel 6 rotation and be arranged on rotation seat 7 rotates and carries out knitting together.Because the inner ring 51 of bearing B5 is held out against by screw 8, therefore, when driving wheel 6 and rotation seat 7 rotate, the inner ring 51 of bearing B5 is also along with rotating together, and the outer ring 52 of bearing B5 is motionless.

A kind of circular loom syringe of the utility model slow-roll stabilization device, make the rotational stability of needle cylinder device 1 jointly be supported by bearing A3 and bearing B5, because screw 8 holds out against the inner ring 51 of bearing B5, eliminated the play of bearing A3, bearing B5, therefore driving wheel 6 is in the situation that is subject under the effect of transmission device radial load can not occurring skew shape rotation braiding, rotation braiding under skew shape is not occurring in needle cylinder device 1, so fabric quality is all right, can not produce woven strain line loosen, tighten inconsistent, quality problems that between upper and lower line, distance is inhomogeneous, weaving thread is crooked etc.

Above-described embodiment is only for the inventive concept of the present utility model of explaining, but not to the restriction of the utility model rights protection, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should fall into protection domain of the present utility model.
