June 5, 1951 J. MANDOUCHITCH SPINNING AND TWISTING SPINDLE Filed June 3. 1949 2 Sheets-Sheet 2 Patented June 5, 1951 UNITED STATES PATENT OFFICE Application June 3, 1949, Serial No. 96,855 In Switzerland May 30, 1948 7 Claims. 1
This invention relates to spinning and doubling or twisting spindles. It is an object of the present invention to provide a spindle which is particularly adapted for high speeds of rotation.
According to an important feature of the invention, the spindle which is of the xind comprising roller members arranged between a fixed holder member and the rotary shaft of the spindle, is provided with at least two roller members one of which is arranged between the fixed holder member and an intermediate rotary member while the other one is arranged between said intermediate rotary member and the shaft of the spindle, axial thrust bearings being provided to define the axial positions of the intermediate rotary member and of the spindle shaft respectively relative to the fixed holder.
The annexed drawings diagrammatically show by way of examples two spindle constructions embodying the invention.
In the drawings:
Figure 1 is an axial sectional view of the first construction, and
Figure 2 is an axialsectional view of the second construction.
According to the embodiment of the invention shown in Figure 1, the spindle comprises a bobbincarrier I, driven in rotation by means of a wharve 2. The bobbin carrier l is secured to the shaft or blade having a downward extension 3 and a cylindrical middle portion 4. On the latter is arranged a roller bearing 5 carrying an intermediate rotary member 6.
The tubular shaped member 6 surrounds the conical extension 3 of the blade and carries at its lower end an axial thrust bearing 1 resting on the one hand on the lower end of the blade extension 3, and on the other hand on a fixed pivot 8 rigidly secured to the holder I I.
The rotary sleeve 6 is supported by means of a roller bearing 9 within a recess I0 of the stationary holder H.
The operation of this spindle is as follows: when the bobbin carrier I is driven in rotation by the wharve 2, the intermediate rotary member 6 is driven too in rotation by friction. However, as the said intermediate member rotates freely, its speed of rotation is defined on the one hand by the friction of the rollers of the roller bearing 9, and on the other hand by the friction of the rollers of the roller bearing 5. The member 6 will thus reach a speed which is intermediate between that of the blade 4, 3 and speed zero of the holder H, so that the effective speed of the bobbin carrier I can be substantially increased.
If, for instance, the roller bearings 5 and 9 are calculated to allow speeds of 6,000 revolutions per minute, the bobbin carrier I can be driven at a speed of 12,000 R. P. M., since the relative speeds between the stationary holder H and the rotary member 6 on the one hand and between said rotary member 6 and the spindle blade 3, 4 on the other hand do not overreach then 6,000 R. P. M.
Lubrication is insured on the one hand by the tapering of the blade extension 3 and on the other hand by the outer conical shape of a sleeve l2 surrounding and secured to the rotary member 6.
The axial thrust bearing 1 is preferably made of synthetic jewel in order to reduce the friction and the wear. In the construction shown in Figure 2, the blade 23 of the spindle is hollow and rotates through the medium of two roller bearings 25 about a rotary member 26. The lower end of the latter which projects from the lower end of the hollow blade 23 is rotatably supported within the recess 30 of the tubular holder 3i by a roller bearing 29 and an axial ball thrust bearing 21, 28.
The bobbin carrier 2| further rests on the upper end of the member 26 by means of an axial thrust bearing 33.
In this second construction, the roller bearings 25 and 29 have the same diameter, that is to say their roller races have the same diameter. The member 26 will be thus likely driven at about one half of the rotation speed of the bobbin carrier 2|. Furthermore a rotary member 26 of smaller diameter can be provided, thus obtaining for a given speed a comparatively low circumferential speed of this member. Now the speed of rotation of a member with respect to the other is limited principally by the difference between the circumferential speeds which determines the speed of rotation of the rollers.
Lubrication of the roller bearings is insured on the one hand by the tapered portion 3-1 of the member 26 and, on the other hand, by a conical sleeve 35 secured to the inner wall of the hollow blade 23, said sleeve being further intended as a spacing member between the two roller bearings 25.
It appears clearly from the foregoing and from the annexed drawings that the spindle according to the invention is designed for much higher speeds than the roller or ball bearing spindles known up to now.
What I claim is:
1. A spinning and twisting spindle comprising a stationary holder member, a rotary shaft for 2. A spinning and twisting spindle comprising a tubular stationary holder member, a tubular intermediate rotary member within said tubular stationary holder member, at least one roller bearing between said stationary holder member and said intermediate rotary member, a rotary center shaft for carrying a yarn package and having its rear portion extending Within said tubular intermediate rotary member, at least one roller bearing between said tubular intermediate rotary member and said center shaft, an axial thrust bearing closing the lower extremity of said tubular intermediate rotar member and rotatably supporting the lower end of said center shaft, said thrust bearing resting on a pivot secured to the lower end of said tubular stationary holder member, and a wharve secured to the upper end of said center shaft for driving it in rotation.
3. A spinning and twisting spindle as claimed in claim 2, wherein the lower portion of the rotary center shaft is conical for lubrication purpose.
4. A spinning and twisting spindle as claimed in claim 2, wherein the tubular intermediate ro tary member carries an upwardly tapered outer sleeve for lubricatio :purpose.
5. A spinning and twisting spindle comprising "portion of said intermediate rotary member extending therein, two roller bearings between said tubular portion of the center shaft and the portion of said intermediate rotary member extending therein, a ball thrust bearing between the lower end of said stationary holder member and the lower end of said intermediate rotary member, a thrust bearing between the upper end of said intermediate rotar member and the bottom of said tubular lower portion of the center shaft, and a wharve secured to the upper end of said center "shaft for driving it in rotation.
6. A spinning and twisting spindle as claimed in claim 5, wherein the tubular lower portion of the center shaft is provided with a downwardly tapered inner sleeve for lubrication purpose.
7.. A spinning and twisting spindle 'as claimedin 'claim 5, wherein the lower end of the intermediate rotary member is conical for lubrication purpose.
