Description

Hollow swing shaft structure about eccentric formula

Technical Field

The utility model relates to an eccentric hollow swing shaft structure; belongs to the technical field of textile machinery.

Background

The existing loom type generally adopts a seamless steel pipe as a machine type of a swing shaft main body, the swing shaft swings back and forth through the seamless steel pipe, the higher the rotating speed is, the larger the vibration of the swing shaft is, the larger the vibration of the whole loom is, the centrifugal force at the center position of the swing shaft is increased, the inertia bending amount is generated in the movement of the swing shaft, the instability of the work of the swing shaft is caused, the force path is not uniform, in practice, the left and right tightness of the distribution of warp yarns in warp yarns and weft yarns is inconsistent, and the weft yarns in the shuttle are easy to collide, so the operation speed and the efficiency value of the loom are difficult to improve due to the reason.

Disclosure of Invention

Technical problem to be solved

In order to solve the above problem, the utility model provides a hollow axle structure that sways about eccentric formula.

(II) technical scheme

The utility model relates to an eccentric hollow swing shaft structure, which comprises a steel reed, a reed pressing plate, a balancing weight, a swing shaft, a sley and an auxiliary support; the sley is provided with a steel reed; a reed pressing plate is arranged at one end of the steel reed; one end of the sley is connected with a swing shaft through an auxiliary support; the bottom end of the swing shaft is provided with a balancing weight.

Further, the balancing weight can be provided with an angle, and the angle is variable.

Furthermore, the auxiliary supports are bearings and are respectively arranged at two ends of the swing shaft.

Furthermore, the swing angle of the swing shaft is variable, wherein the front solid position is set to be a fixed value, and the rear solid position is variable.

Further, the balancing weight is a split type balancing weight or an integral type balancing weight.

(III) advantageous effects

Compared with the prior art, the utility model, it has following beneficial effect: the utility model discloses a hollow beating-up mode of rocking axle structure about eccentric formula hollow rocking axle structure adopts the hollow rocking axle structure of the additional counter weight form of eccentric formula, use hollow rocking axle will be low many for solid rocking axle in the cost, on the range of application, hollow rocking axle application scope is more extensive, the structure is simple relatively, processing and installation are more advantageous, so solved the above shortcoming of hollow rocking axle's own existence, the beating-up mode of the hollow rocking axle structure of the additional counter weight form of applied eccentric formula has very big technical promotion space and market potential space.

The technical characteristics are as follows: size, weight, length through can changing the axle body of swaing to this matches corresponding counter weight parameter, reaches corresponding functioning speed's maximize effect of swaing the motion, has promoted machine stability in service and high-efficient high-speed performance, changes the axle subassembly barycenter position coordinate of swaing through the counter weight mode, increases the dynamics of beating up, reduces the axle that swaps and shakes produced inertia bending vector, centrifugal force and shake, makes the axle system work of swaing more stable, and machine vibrations also can reduce relatively.

Drawings

Fig. 1 is a schematic structural view of a rocking shaft assembly of the present invention.

Fig. 2 is a schematic view of the split counterweight structure of the present invention.

Fig. 3 is a schematic side view of the loom of the present invention.

Fig. 4 is a schematic view of the integral counterweight structure of the present invention.

Integral balancing weight: mainly be applied to long sley width rocking shaft, the integral stability that has very strong to this strengthens rocking shaft rigidity in the motion, reduces the crookedness of inertia in-process, and the weight of balancing weight can be through changing material density, length, thickness, in order to play different effects.

Split type balancing weight: mainly be applied to short reed width rocking shaft to this strengthens rocking shaft rigidity in the motion, reduces the crookedness of inertia in-process, and split type has the convenience and the commonality of adding and subtracting weight and change counter weight quantity, and the weight of balancing weight can be through changing material density, length, thickness, in order to play different effects.

1-reed; 2-a reed pressing plate; 3-a balancing weight; 4-a rocking shaft; 5-slay; and 6, auxiliary supporting.
