Definitions

  • This invention relates to a top roller for spinning machines. Due to their smooth operation and the minimum care which they require, top rollers of spinning machines which incorporate anti-friction bearings show great advantages over other types. Still, this appliance does not enjoy the popularity it should due to its advantages. The reason is the high price of the conventional construction, various operational deficiencies, and frequently the imperfect sealing of the bearings against flying fibrous matter.
  • rollers One of the main reasons for the expensiveness of this roller type lies in the fact that they must be made to fit the pitch of the respective spinning machine or the distance between rollers.
  • the rolling member bearings are usually standardized and the adjustment to the respective pitch is effected by application of individually machined shaft ends and go-betweens.
  • the high price of the individual machining, the combination of different parts into a single shaft often results in faulty alignment.
  • top rollers which are designed as loose rollers with two independently running roller bodies.
  • These top rollers run upon double ball bearings of the angular contact bearing type in which the application of gobetweens of different lengths allow a simple adjustment of the clearance to the effect that the bearing is practically rigid as to tilting.
  • Figure 1 is an axial sectional view of a pair of top rollers set for minimum spacing
  • Figure 2 shows the same pair of rollers set for maximum pitch with the same shaft length
  • Figure 3 shows in an axial sectional view a pair of modified top rollers, employing reversible outer sleeves set for small pitch;
  • Figure 4 shows the same rollers as in Figure 3 with reversed outer sleeves set for a larger pitch
  • Figure 5 shows a single top roller, illustrating an offthe-middle-application of force as may occur when in operation
  • Figure 6 illustrates a top roller and the connection between a spacing ring, located between the two sets of balls, and the outer race of the bearing;
  • Figure 7 is a sectional view of a top roller, illustrating nrice 2 the securing of the outer sleeve upon the bearing through the medium of two oval spring clips;
  • Figure 8 is a sectional View along the line A-B of Figure 7;
  • Figure 9 is a longitudinal sectional View of a top roller with end journal, employing a snap ring to secure the outer sleeve upon the bearing;
  • Figure l0 shows, in an enlarged fragmental View, the position and operation of the snap ring of Figure 9.
  • the shaft 1 which is machined out of a single piece bears two ball bearing grooves 10 in which lie the balls 2 and thereupon an annular member or the outer races 3.
  • the axial guidance is effected by an intermediary ring 4.
  • the outer sleeves 5 which bear an elastic covering 6 are snugly tted upon the annular member 3, off the vertical median plane through said annular member, so that the longer end portions of the outer sleeves show toward the neck il of the shaft 1.
  • Both rollers which are journalled on the cornmon shaft 1 turn independently as the so-called loose rollers are known to.
  • Identification marks on the outer end of the sleeve may indicate the out-of-middle position of the outer sleeves whereby the pitch may easily be determined before assembly.
  • shafts 1 as well as the bearings and outer sleeves may inexpensively be produced in series as standard parts. The conventional adjustment. to the respective pitch by individual production of the parts may thus be abandoned.
  • a rigid bearing is usually ensured by providing two angular contact bearings which are set axially in such a manner as to reduce the clearance of the bearing as far as possible.
  • all ball bearings of the conventional type are very expensive.
  • the invention provides a simplified double ball bearing of the angular contact bearing type in which only the inner races on the shaft which are subject to greater stress are fitted with grooves 10, whe-reas the outer races 13 remain cylindrical.
  • the clearance of the bearing and thus its tilting zchances are reduced to a minimum by the intermediary rings 4.
  • Such go-betweens will be on hand in various suitable lengths.
  • the required length of part 4 is determined by a simple measurement.
  • the roller as in Figure 1 is more perfectly sealed inasmuch as the outer sleeve receives a bushing 17 which forms a triing clearance 18 with the shaft 1. Only a bearing engagement rigid as to tilting can prevent grinding of the bushing 17 or the outer race 3, respectively, upon the shaft 1 which would be accompanied by irregularities in the operation of the top roller and result in uneven yarn.
  • FIG. 1 shows an example employing afsl'ioulder 19 and bushing 17.
  • the outer vsleeve 5 may be entirely closed at the shoulder end as indicated by broken lines in the left hand roller of FigureA i, whereby the cleanliness is increased during operation because the metal cap 2'3 is preventedV from getting fouled.
  • the bushing' 17 which is held in position by means of an annular spring 26 improves the sealing of the bearing due to the small clearance 18.
  • Other possible methods of holding the bushing in position would be e. g. a bayonet joint or screw threads. This bushing may also be replaced by similar objects which vserve the same purpose.
  • the axial positioning of the outer sleeve may also be effected by employment of Vtwo annular springs 27 as in Figures 7 and 8. It is recommended to give the annular spring 27 an oval shape so it will lie under tension in the groove 28 of the outer sleeve. The projecting arcuate portions 29 are permitted to enter into this groove 28 when the outer sleeve is pushed over the bearing since the latter is either somewhat conical or rounded off at either end.
  • a single one may be employed to fasten the outer sleeve as in Figure 9.
  • the outer race is provided with a groove 3i) into which the spring snaps.
  • FIGS. 3 and 4 V show a pair of top rollers which embody outer sleeves according to Figures 7 and 9.
  • the complementary grooves of the annular member Vand outer sleeve, which receive the snap ring are not in the center of the outer sleeve, two different pitches are provided by simply reversing the outer sleeve 5.
  • pitches may be obtained ranging from a minimum amount T1 to a maximum amount T2.
  • the end journals may be pressed onto the ends of the shaft, provided the sealing caps over the bearings are avoided. Variations in the length of these end journals facilitate accommodation to the various applications. In this case the lubrication will take place through holes 33 which end in anoil groove 34. A small narrow gap 35 provides the seal-
  • the novel top rollers may therefore be employed in all machines which occur in spinning mills.
  • Top roller for spinning machines comprising a shaft, a pair of rollers, one of said rollers being mounted at each end of said shaft for 'independent rotation, a single bearing for each of the rollers, each bearing including two series of balls, the shaft constituting the inner ball races, a single annular member serving as outer races, a ring between said two series of balls, fastening means connecting said ring and annular member to one another, an outer sleeve fitted upon the annular member of each of the rollers and secured in its position, and a covering placed around each outer sleeve.
  • each of said rings being such as to reduce the play of the bearings to a minimum.
  • the shaft having two annular grooves to receive the two series of balls, and the annular member having a smooth inner surface.
  • each outer sleeve means to secure each outer sleeve on its annular member, the securing means for each outer sleeve including a shoulder formed in the outer sleeve, the annular member abutting against said shoulder, a bushing abutting against the annular member, complementary grooves in the ⁇ outer sleeve and bushing, and an annular spring received in said grooves, the bushing, depending on the width thereof, permitting the outer sleeve to be lengthwise adjustably positioned on the annular member.
  • each outer sleeve on its annular member, the securing means for each outer sleeve including at least a single groove in the outer sleeve, and a resilient snap ring received in said groove and engaging the respective annular member.
  • the securing means for each outer sleeve including, in addition to the groove in each of the outer sleeves, a complementary groove in the respective annular member, the resilient snap ring being received in the complementary grooves.
  • the complementary grooves being asymmetrically arranged with respect to the vertical median plane through the outer sleeve, making the reversal of the outer sleeves possible.
  • the securing means for each outer sleeve including two grooves in the outer sleeve, and a resilient snap ring received in'each of said grooves, said snap rings engaging the end portions of the bearing.
  • the support of the two series of balls being formed, in addition Vto the shaftl and annular member, by the frontal or end faces of the ring.
