Abstract
The utility model relates to a transmission system of a high-speed wire feeding machine, in particular to a hollow shaft of a high-speed wire feeding machine with a shock absorption device. The hollow shaft is installed on a bracket of the wire feeding machine through a bearing; surface convexes are arranged on the hollow shaft at the interference position with the inner ring of the bearing; the inside surface of the inner ring of the bearing is inward to form trench concaves; the shape of the convexes on the hollow shaft is matched with the shape of the concaves on the inside surface of the inner ring of the bearing. When the hollow shaft designed by the utility model trends to slide bilaterally or vibrate vertically corresponding to the inner ring of the bearing, the hollow shaft is automatically guided by the inner ring of the bearing with the trench concaves to be adjusted to the original position; vibration is reduced; simultaneously, the contact surface is also increased through curved surface contact, so that vibration is reduced; practical tests prove that a shock absorption effect of involute-shaped convexes and the trench concaves is good.
Description
Technical field
The utility model relates to a kind of delivery system of high-speed rod Laying head, specifically, relates to a kind of high-speed rod Laying head hollow shaft that has damping device.
Background technique
Fig. 1 shows the basic functional principle of prior art high speed wire rod Laying head silking process: Laying head input shaft 1 connects hollow shaft 3 by bevel-gear sett 2, hollow shaft 3 is connected with laying head 5, at laying head 5 spinneret 4 is arranged fixedly, spinneret 4 has the free radian of certain curvature, like this, and driven by motor input shaft 1, input shaft 1 drives laying head 5, laying head 5 drives spinneret 4, and like this, the steel wire of process spinneret 4 has just been coiled into the circle with fixed diameter.
But, in the course of the work, because the axial trace of hollow shaft 3 is mobile, and radially vibrations bring the vibration values of entire equipment to exceed standard, and make that the working efficiency of Laying head is low, therefore, by reducing the vibrations of hollow shaft, improve the working efficiency of whole Laying head, be feasible in principle.
Mentality of designing of the present utility model just is, overcomes defective of the prior art, and the shape of hollow shaft is made certain improvement, develops a kind of high-speed rod Laying head hollow shaft that has damping device.
The model utility content
The purpose of this utility model is, a kind of high-speed rod Laying head hollow shaft that has damping device is provided, and for reducing the vibrations of Laying head, improves the manufacturing efficiency of Laying head.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of high-speed rod Laying head hollow shaft that has damping device, described hollow shaft is installed on the Laying head support by bearing, interference place with bearing inner race on the described hollow shaft is provided with protrusion of surface, the internal surface of described bearing inner race inwardly forms ditch shape depression, and the concave shape of the shape for lugs on the described hollow shaft and described bearing inner race internal surface is complementary.
The sectional shape of described hollow shaft protrusion of surface place is camber line or parabola or involute.
The outer ring of described bearing and inner ring form by two semi-circular structure butt joints, and described bearing outer ring outside is provided with the installation auricle, and described bearing outer ring is installed on the Laying head support by auricle is installed.
The beneficial effects of the utility model are:
The hollow shaft of the utility model design and interference place of bearing are provided with projection, interference place of hollow shaft and bearing adopts curved surface to cooperate, when having with respect to bearing inner race, hollow shaft horizontally slips or during the trend of vertical tremor, such structure makes hollow shaft have adaptive trend, the automatic hollow guide shaft of bearing inner race that is ditch shape depression is adjusted to the home position, reduces vibrations, simultaneously, the curved surface contact has also increased surface of contact, has reduced vibrations.Through actual tests, the damping effect of the projection of involute shape and ditch shape depression is best.
Description of drawings
Fig. 1 is the principle schematic of Laying head silking process in the prior art;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is that the A of Fig. 2 middle (center) bearing is to the structure for amplifying schematic representation.
Embodiment
The present invention is further described below in conjunction with drawings and Examples:
Embodiment: referring to Fig. 2, Fig. 3.
A kind of high-speed rod Laying head hollow shaft that has damping device, described hollow shaft 3 is installed on the Laying head support by bearing 6, interference place with bearing 6 inner rings 62 on the described hollow shaft 3 is provided with protrusion of surface 7, the internal surface of described bearing inner race 62 inwardly forms ditch shape depression, and the concave shape of the shape for lugs on the described hollow shaft 3 and described bearing inner race 62 internal surfaces is complementary.
The sectional shape of described hollow shaft protrusion of surface place is camber line or parabola or involute.
The hollow shaft of the utility model design and interference place of bearing are provided with projection, interference place of hollow shaft and bearing adopts curved surface to cooperate, when having with respect to bearing inner race, hollow shaft horizontally slips or during the trend of vertical tremor, such structure makes hollow shaft have adaptive trend, the automatic hollow guide shaft of bearing inner race that is ditch shape depression is adjusted to the home position, reduces vibrations, simultaneously, the curved surface contact has also increased surface of contact, has reduced vibrations.Through actual tests, the damping effect of the projection of involute shape and ditch shape depression is best.
The outer ring 61 of described bearing 6 and inner ring 62 form by two semi-circular structure butt joints, and described bearing outer ring 61 outsides are provided with installs auricle 63, and described bearing outer ring 61 is installed on the Laying head support by auricle 63 is installed.
What embodiment of the present utility model announced is preferred embodiment; but be not limited thereto; those of ordinary skill in the art; very easily according to above-described embodiment; understand spirit of the present utility model; and make different amplifications and variation, but only otherwise break away from spirit of the present utility model, all in protection domain of the present utility model.
