Definitions

  • the swivel axles of the UNITED STATES PATENTS housings are arranged adjacent to the drive shaft and 3,511,045 5/1970 Bures et a1 57/5891 Parallel thereto, 50 that when the housing is swivelled 3,667,205 6/1972 Brazda et a1 away, the driven gears are lifted off the driving gears 3,685,270 8/1972 Bartling 57/5895 of the drive shaft. 3,760,576 9/1973 Le Chatelier et a1 57/58.89 X
  • the present invention relates to a machine for continuous spinning of textile fibres by means of spinning rotors and supply and disintegrating rollers associated thereto, having a stationary longitudinal shaft with gears for driving said supply organs as well as swivel mounted housings containing said supply and disinteg'rating'organs, having driven gears which are in engagement with the gears of said longitudinal shaft.
  • the longitudinal shaft is surrounded by a stationary tube which serves as the swivel axle, on which the swivel members are mounted.
  • a stationary tube which serves as the swivel axle, on which the swivel members are mounted.
  • this tube In orderto transmit the drive to the swivel housing, it is necessary to provide this tube with an opening at every spinning point so that the gears of the longitudinal shaft can come into engagement with the driven gears of the swivel member. These openings represent a weakening of the tube.
  • the distance between bearings of the longitudinal shaft is greater than the length of the tube. The sag of the longitudinal shaft is then relatively great, which necessitates, in turn, large diameters for the longitudinal shaft and the tube.
  • the longitudinal shaft, the swivel axle arranged parallel thereto, as well as the driven gear are arranged one to the other in such a manner that the driven gear is brought into engagement tangential or almost tangential to and with the gear of said longitudinal shaft in a circular path.
  • the longitudinal shaft is freely accessible, as it is arranged without being covered in any way by a tube, which especially simplifies maintenance and fitting work.
  • the distance between bearings of the longitudinal shaft can now be selected as small as desired, so that its sag remains minor.
  • the distance between bearings between two sections of shaft to be coupled longitudinally can, on the other hand, be kept larger than previously, so that a softer coupling is possible, permitting any alignment defects to be compensated more easily.
  • the driving gear acts on a zone of the driven gear which is not subjected to strain during the swivelling operation, thus resulting in gentle engagement.
  • the operation of swivelling into engagement can be designed especially advantageously if the longitudinal shaft between swivel axle and driven gear is located in the immediate vicinity of the swivel axle.
  • a greater distance means a longer swivel time, and thus more gentle swivelling into engagement.
  • the swivel operation would have to be limited by a stop in order to prevent further motion beyond the position of the teeth for the operating condition, which couldotherwise result in tooth breakage. If, however, the longitudinal shaft is located between swivel axle and driven gear, there is no need for a stop, as the driven gear would come out of engagement again if swivelled too far, making tooth breakage impossible.
  • the driven gear in which the outer area of its tooth width has a shape which deviates from the profile which is in engagement during the operating condition. It is preferable for the driven gear to have a larger tip circle diameter on one side, so that in this section the teeth taper to a point. This aids the gentle engagement of the teeth.
  • the driven gear which is to be swivelled into engagement has an elastic perimeter zone.
  • This perimeter zone can be of an elastic plastic. Damage to the driven gear when swivelling into engagement is reliably avoided because of the existing elasticity.
  • the elastic portion of this driven gear is preferably designed as an interchangeable ring, either with or without teeth.
  • FIG. 1 shows a section through the machine according to the invention, with closed swivel housing
  • FIG. 2 shows a section through the same machine with open swivel housing
  • FIG. 3 shows the driven gear swivelling into engagement with the gear of the main drive shaft
  • FIG. 4 shows a tooth of the driven gear with larger tip circle diameter at the point of engagement
  • FIG. 5 shows a tooth of a driven gear designed in two sections axially, whereby the engaging section has a larger tip circle diameter
  • FIG. 6 shows a driven gear with a tapered ring without teeth attached axially thereto
  • FIG. 7 shows the engagement phase of the embodiment according to FIG. 6 in smaller scale
  • FIG. 8 shows an embodiment in which the driven gear is arranged between swivel axle and drive shaft
  • FIG. 9 shows an embodiment similar to FIG. 8.
  • FIG. 1 shows the machine, generally comprising a stationary section which includes, as the supporting elements, the spinning chamber housing 1, the drive housing 2 and a bearing housing 3, and a swivel section which includes the swivel housing 4 and its cover 5.
  • the spinning rotor 6 Arranged in the supporting elements of the stationary section are, generally, the spinning rotor 6, the rotor drive 7, a longitudinal shaft 8 for driving the supply members, as well as the swivel axle 9, arranged parallel thereto, for the swivel housing. All other operating elements have been left away for reasons of clarity. For the same reason, no description will be made of the spinning method, as those skilled in the art are familiar with this operation.
  • the major operating elements of the swivel housing 4 are a supply roller 10, a disintegrating roller 11, extraction means 12 and a driven shaft 15.
  • the supply and disintegrating functions will also not be described, as, on the one hand, those skilled in the art are also familiar with them and, on the other, they do not belong to the subject matter of the invention.
  • the supply roller 10 is driven from the longitudinal shaft 8 by means of a gear 13 arranged thereon, a driven gear 14, which are preferably gears with helical teeth of less than 45, and a driven shaft 15 by means of a second pair of gears with helical teeth l6, 17.
  • the indicated example describes only one supply roller 10 with its drive means. In actual practice, however, the plurality of spinning points, and thus a plurality of supply rollers, are provided one next to the other in the longitudinal extension of the machine.
  • driven shaft 15, and thus the axis of driven gear 14 is arranged in such a manner that it describes a right angle with the radial plane of swivel axle 9.
  • the operating position calls for longitudinal shaft 8 to also be located on the radial plane, so that in operating position the teeth of driven gear 14 extend tangential to gear 13 of longitudinal shaft 8. This provides the advantage that minor deviations from the operating position are possible without the risk of damage. It is not necessary to provide a stop limiting the maximum engagement of the teeth.
  • FIG. 3 shows schematically how driven gear 14 swivels into engagement with gear 13 when driven shaft 15 is swivelled about swivel axle 9.
  • Longitudinal shaft 8 and swivel axle 9, arranged parallel thereto, are mounted in a stationary manner.
  • the center of driven gear 14 describes an arc Kl, whose center M is located in swivel axle 9.
  • FIG. 3 further shows the circular path K2 of the distance travelled by the pitch circle of the teeth of driven gear 14. It can be seen that driven gear 14 comes into engagement in a circular motion K2, whereby the imaginary extension of the arc does not extend through the center of longitudinal shaft 8, but almost tangential only through a perimeter zone. Thus, at the commencement of the swivel motion a different area of the teeth of driven gear 14 comes into contact with the teeth of driving gear 13 of longitudinal shaft 8 than subsequently in the operating condition. Possible wear or damage in this area of driven gear 14 does not therefore result in disturbance of the operating condition.
  • FIG. 4 shows an advantageous development of driven gear 14, of which only one tooth is illustrated.
  • area 14a of the tooth comes into engagement with gear 13 first; in the operating condition, on the other hand, area 14b of the tooth.
  • area 14a of the tooth is designed so as to taper outwardly to a point, which results in an increase of the tip circle diameter by a minor amount of approximately 1 mm (0.039 in).
  • these two areas of the teeth can also be designed as separate components (14a1, 14111).
  • a preferably tapered ring 14a2 (FIG. 6) without teeth can also be employed which, according to FIG.
  • the preferably elastic tapered ring l4a2 is designed in such a manner that it is in a contacting relationship with gear 13 only during the swivelling phase but not in the operating condition.
  • swivel axle 9 and longitudinal shaft 8 are arranged as closely as possible one to the other and for longitudinal shaft 8 to be located between swivel axle 9 and driven gear 14 in the operating condition in order to permit swivel path K2 to extend in the desired manner according to FIG. 3.
  • FIGS. 1 to 7 are especially well suited for cylindrical pairs of gears with helical or worm teeth.
  • FIGS. 8 and 9 show practical examples in which swivel axle 9 and longitudinal shaft 8 are either not arranged in the immediate vicinity one to the other or in which longitudinal shaft 8 is not arranged between swivel axle 9 and driven gear 14b3, 14b4.
  • the arc of driven gear 14b3, 14124 is not uniform throughout the width of the teeth and its tip circle diameter is matched to the swivel radius for swivelling into engagement.
  • a spinning machine comprising:
  • each of said spinning units including spinning means, a drivable supply roller for assisting in supplying fibrous material to said spinning means, and a swivel housing which is pivotable about a swivel axle and which carries said supply roller,
  • a longitudinal drive shaft extending adjacent said at least one spinning unit and including a driving gear for each of said at least one spinning units, said drive shaft being spaced from the respective swivel axles of said swivel housings,
  • said transmission means including a driven gear carried by each of said swivel housings which is selectively drivingly engageable with said driving gear in dependence on the position of the respective swivel housmg.
  • each of the respective driven gears is positioned in a respective one of said swivel housings such that it moves substantially tangentially to the circumference of an associated driving gear upon movement of the respective swivel housing to a position which effects engagement of said respective driven and driving gears.
  • said transmission means includes a shaft carried by said swivel housing, said shaft supporting said driven gear at one end thereof and supporting a further gear at the other end thereof, said further gear being in driving engagement with said supply roller.
  • said spinning means includes a spinning rotor, and wherein said drive shaft extends parallel to each of the respective swivel axles.
  • said driven gear has an elastic perimeter zone which engages the driving gear of the drive shaft first as the swivel housing is closed.
