Abstract
The invention relates to a compressing roller used in weaving machine, especially deforming machine. The compressing roller comprises an outer sleeve (1) with a covering (2); the outer sleeve is rotatablely supported relative to a bearing shaft (9) by a rolling bearing, especially a radial ball bearing (6); the inner race of the radial ball bearing (6) is contained by an outer bearing part (7); to the degree of swing motion allowed by the free space (13) identified by the angle alpha, the outer bearing part transversely on the bearing shaft (9) (angle omega) can swing on the spherical surface (10) of the swing apparatus (8) together with the outer sleeve (1), the covering sleeve (3) and the covering (2).
Description
Technical field
The present invention relates in a kind of weaving loom, the hold-down roller in the Texturing Machines particularly, it comprises an outer sleeve that has a coating.The hold-down roller of this form is to be provided with like this in weaving loom: promptly it presses to the drawing-in roller of a rotation with its coating, wherein, has a long filament to be guided through machine in this way between this drawing-in roller and coating, and may be simultaneously drafted.
Background technology
For example by known a kind of textile machines hold-down roller among the DE-A 197 33 564, it comprises an outer sleeve that has a coating, and this outer sleeve passes through a rolling bearing, particularly radial ball bearing with respect to a reach rotatably support.Be provided with a pendulous device in addition, by this pendulous device, outer sleeve can be swung around an axle transverse to the reach setting.This pendulous device guarantees, above-mentioned hold-down roller can mate with coating by crooked or other error and abuts on the drawing-in roller always exactly parallelly, and long filament can be transferred or drawing-off no problemly.
Summary of the invention
Therefore the objective of the invention is, guarantee the swing (angle Ω) of hold-down roller by simple method.Settling mode according to this task of the present invention is as follows: have a kind of spherical form because of reach (rotatably support outer sleeve thereon) in the inner circle area of ball bearing, and become 90 degree that the plane of two parallel interval is arranged with spherical form.Realized oscillating motion by spherical form, because spherical form peace bread encloses outer bearing parts, these outer bearing parts are fixedly mounted in the inner ring of radial ball bearing with its columniform overall diameter, and these outer bearing parts surround spherical reach end on the one hand and surround the plane of two parallel interval on the other hand with its in-profile in addition.Other structures of reach and outer bearing parts guarantee that described oscillating motion can carry out, and this oscillating motion is defined by free space (with the angle [alpha] sign).Be installed in the outer bearing parts and the long life-span of this combination bearing in order to ensure reach, the outer bearing parts are repeatedly slotted on its circumference, and the free space of the required possibility of reach being installed and having prepared to be used for the grease storage is provided like this.In addition outside on the overall diameter of parts of bearings, on the spherical side of reach, flexible antelabium (Lippen) is arranged, this antelabium guarantees that the outer bearing parts can be engaged in the inner ring of ball bearing jointly with reach, and be fixedly mounted in the inner ring by this way, and must extra outward rigid bearing parts.In another optional structure of pendulous device, the outer bearing parts are axially fixed in the inner ring by a locking collar, and reach is made of two kinds of different materials.
Description of drawings
Below by means of two groups of accompanying drawings totally four width of cloth figure explain the present invention in detail.In the accompanying drawing:
Longitudinal sectional view of Fig. 1 according to hold-down roller of the present invention;
Fig. 2 is according to the A-A cutaway view of the hold-down roller cross section of the pendulous device of Fig. 1 prompting;
Fig. 3 is according to the longitudinal sectional view that has the hold-down roller of the axial restraint device of optional outer bearing parts in inner ring of the present invention;
The optional embodiment of a reach of Fig. 4 and the cross section view of pendulous device.
The specific embodiment
Have an outer sleeve 1 according to the hold-down roller by Fig. 1 and Fig. 2 of the present invention, put a coating sleeve 3 that has a coating 2 thereon.The outer sleeve of making to chipless 1 comprises a sleeve inside section 4, and this sleeve segment and outer sleeve 1 are fixedly linked, and has a lubrication hole 5 at its center.Radial ball bearing 6 and outer bearing parts 7 can add lubricating oil by the lubricant cavity 14 of these lubrication hole 5 usefulness pendulous devices 8.Radial ball bearing 6 is admitted by the interior diameter of outer sleeve 1, and axially mounting is on sleeve segment 4.The inner ring of radial ball bearing 6 is admitted by outer bearing parts 7, these outer bearing parts guide on the spherical surface 10 of pendulous device 8 transverse to reach 9 (angle Ω), and with 10 one-tenth 90 degree of spherical surface, plane 11,12 and outer sleeve 1, coating sleeve 3 and the coating 2 of two parallel interval of pendulous device 8 can be finished oscillating motion jointly, carry out on the degree of being permitted these oscillating motions by the free space 13 of angle [alpha] sign.Outer bearing parts 7 are to be designed to like this, make it on the side of long reach 9, radial ball bearing 6 additionally is protected by the dish type structure 15 of outer bearing parts 7.Selectively, as the details by Fig. 3 illustrated, the outer bearing parts can be fixing by a locking collar 16.
The optional embodiment of a reach 17 shown in Figure 4 and pendulous device 18 is promptly by using different material-combinations.
