Synthetic yarns are formed in spinning turbine which are supported on a rotatable shaft, driven by a source of rotary power. The shaft is journalled in a bearing assembly which is rigidly secured within a mounting hole or fixture in a frame or other machine supporting member. The shaft is driven at high speed to spin the turbine and thus centrifugally form or process the yarn. The economics of spinning turbine operation (i.e. maximum yarn output) dependsprimarily on the rotary speed of the turbine; the higher the rotary speed, the more yarn is produced per unit time.
The rotary speed of the spinning turbine, however, is substantially limited by the known bearing arrangements to approximately 30,000 rpm. The cause of such a limitation is to be found in the rigid mounting of the bearing assembly in the machine frame. As a consequence, vibrations generated during operation of the spinning turbine are transmitted to the bearing of the turbine shaft subjectingit to undue strain and as a result a rotary speed beyond the stated 30,000 rpm. cannot be successfully obtained nor can satisfactory yarn be produced at that speed.
It is an object of the invention to mount the spinning turbine in the spinning machine in such a manner that its rotary speed may be increased substantially and the yarn output correspondingly incresed.
It is a particular object of the present invention to provide an improved bearing apparatus for spinning turbines, which reduces the effects of vibration and excessive speed so as to provide a smooth, more stable rotation.
These objects, others, and numerous advantages will be seen from the following disclosure.
SUMMARY OF THE INVENTION According to the present invention apparatus for mounting the bearing assembly of a spinning turbine is provided comprising a bushing secured by its outer surface to the machine frame and having its inner surface radially spaced from the exterior of the bearing assembly. Interposed between the bushing and the bearing assembly is a resiliently yieldable member secured to at least a portion of the inner surface of the bushing and only to a portion of the outer surface of the bearing assembly to thereby mount the assembly to the bushing with a radial clearance about a substantial length thereof.
This arrangement has the advantage as compared to the .known rigid mountings of making the bearing as sembly capable of free vibration in the machine frame so that the stress forces on the' bearing are substantially reduced permitting high rotational speeds. Correspondingly the noise caused during operation of the turbine is decreased providing quieter operation.
The invention is capable of various embodiments. In one advantageous embodiment a sleeve is coaxially arranged within the bushing to receive the housing assembly and the resiliently yieldable material is arranged between the sleeve and the bushing fixedly connecting these parts to each other.
Preferably, the bushing envelopes the bearing housing only over a portion of its length and specifically near one of its ends. The bearing housing may be thus deflected within the bushing in any desired radial direction. Forces which would thus be normally ab sorbed by either the frame or bearing assembly are thus absorbed by the resilient yieldable member contributing to a quiet, smooth operation of the turbine.
Rubber or synthetic elastomeric material similar to rubber are used for the yieldable member which is preferably vulcanized or otherwise adhered over the entire circumference of the sleeve and to the outercircumference of the bushing.
According to a second design, the bushing consists of two axially arranged parts which are connected movably with each other by means of the resiliently yieldable material, one of the partsbeing arranged in the machine frame and the other carrying the bearing assembly. In this form the resiliently yieldable member is placed axially between the two parts.
Full and complete details of the present invention follow in the appended disclosure.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. I is vertical sectional view of a turbine bearing assembly and mounting apparatus according to the present invention, and
FIG. 2 is a view similar to that of FIG. 1 showing a second form of the present invention.
DESCRIPTION OF INVENTION 'The figures show only so much of the spinning machine frame and turbine or spinnerette as is necessary to understand the mounting of an individual turbine.
unit. The general-features of a spinning machine, its construction and operation are well known, and it is therefore not believed necessary to fully describe the same here. Those skilled in this art are fully cognizant of such machines and the literature is replete with information of them.
The embodiment of the present invention as seen in FIG. 1 comprises a hollow cylindrical bushing 10 provided with a similarly cylindrical sleeve portion 12 held substantiallycoaxially within it by a resiliently yieldable pad 16. The yieldable pad is made of rubber or similar material capable of vibration and is preferably vulcanized or otherwise secured to the inner surface 14 of the bushing l0-and the outer surface of the sleeve 12. The axial length of the sleeve, as clearly seen from the figure, corresponds only to a portion of the axial length of the bushing 10, extending from the rear end of the bushing inwardly toward the axial center thereof.
The resilient pad 16 extends from the-inner edge of the sleeve 12 in contact with the inner surface 14 of the bushing I0 until it reaches the front end of the bushing 10. In this manner the resilient'yieldable material covers the entire internal surface of the bushing 10. The thickness of the pad 16, however, tapers or decreases in radial dimension as it progresses from the end-of sleeve 12 to the front end of the bushing 10 so that the wall thickness at the front end is less than half the wall thickness between the sleeve 12 and bushing each end, mounted therein by suitable ball or roller bearings. The shaft 20 has fixed to its forward end a spinnerette or turbine 22, and at its rear end a drive wheel or pully 24 which is connected by conventional belt drive or other means to a source of rotary drive power. The bearing assembly, turbine, and .pully mechanisms are w ell known, as indicated earlier, and need not be further described.
Because of the cylindrical exterior of the bearing housing the tapering resilient pad 16 envelopes the exterior thereof without touching it, leaving a free annular space 26 or radial clearance between the bearing and the bushing 10.
The bearing is fixed only circumferentially at the portion to which it is secured to the sleeve l2. Lastly, the exterior surface of the bushing is secured within a mounting hole formed in a support or frame member 28 of the machine in conventional manner.
Alternatively, the sleeve 12 may be omitted and the resiliently yieldable member 16 adhered or vulcanized directly to the surface portion of the bearing housing. The sleeve 12 functions to provide suitable sub-assembly formations for easy replacement. Similarly the tapering extension portion of the resiliently yieldable member may also be omitted and the annular clearance maintained free of the pad. i
It will be apparent that the present concept is embodied in a mount having a bushing securable to the frame and an elastomeric resilient member interposed and securedto at least a portion of its inner surface and to substantially less than all of the entire surface of the bearing assembly.
The operation of the turbine of course conforms the conventional usage. That is, the pully 24 connected to the source of power causes the shaft 20 to rotate the turbine 22 about its central axis. The faster the pully 24 is driven the faster the turbine 22 is rotated.
It is evident from the above and reference to the drawing that the bearing assembly 18 is thus floatingly mounted within the frame. The resilient member 16 envelopingly securedto only a portion of the bearing housing permits the bearing assembly to move'radially' within the free annular space 26. The resiliently yieldable pad 16 secures the sleeve 12 to the bushing 10 while permitting relative vibration and movement between the sleeve and bushing. The tapering radial wall dimension of pad 16 permits a degree of angular deflection of the bearing housing free of contact with the bushing 10 or frame 28. The mounting arrangement thus illustrated enables the bearing assembly to vibrate freely so that any oscillatory stresses generated by the rotation of the turbine are not transmitted to the machine frame 28. Consequently, deleterious and harmful reactionary outer hearing has an inner cylindrical surface the radial dimension of which is greater than that of either the interior bushing' 32 or the bearing housing 30, so that an annular space 40 is formed about the bearing housing 30. Permanentlyfixed, adhered, or vulcanized axially between the opposed slant orwedge. surface of the inner bushing 32 and the outer bushing 34 is a yieldably resilient pad 38 of annular conical configuration. The pad 38 is of generally uniform thickness.
As seen in FIG. 2 this mounting arrangement is suitable for use where the thickness of the machine frame 36 is less than the axial length of the bearing housing 30. It is preferable that the outer bushing member 34 be at least substantially equal to the depth of the frame the inner portion to which-the bearing housing 30 is fixed can thus extend beyond the frame 36. This arrangement is of course suitable for use in the form shown in Fl'G. 1 and has all the advantages described for it.-
opposed inclined or conical faces. This permits the inser'tio'n of an intermediate resilient pad of considerable length. As a result, the bearing housing 30 is permitted a large degree of vibratory movement and radial deflection without transmission of vibrations to the frame. The advantages and benefits of this second embodiment clearly parallel those obtained from the first. v
It will thus be seen thatthe present invention provides apparatus for mounting turbine bearing assemblies in spinning machines capable of permitting the assembly to freely vibrate with transmission of the Various modifications have been shown to the two embodiments. Numerous additional changes, modifications, and variations will suggest themselves to those skilled in this art. lt is intended therefore that the present disclosure be taken as illustrative only of the present invention and not as limiting ofits scope.
