Definitions

  • each motor is mounted on the machine frame and is'provided with a free rotor shaft journal onto which the drawroll is mounted in a manner similar to 21 directly mounted belt pulley (e.g. as shown in German Disclosure l,760,627 and German GM 70, 32, 345, as well as Swiss Pat. Nos. 492,809 and 465,127).
  • the rotor of the drive motor and the drawroll thus are fixed on the same axle which is rotatably supported in so-called bearing end plates at both ends of a stator housing of the motor.
  • Still other arrangements are also known in which a heated godet or drawroll is mounted on one end of a drive shaft while a coupling member is provided at the other end for transmitting the drive power.
  • the drive power in this case, as a rule, is supplied by an individual drive motor of a known construction which is equipped with two bearings for the motor rotor shaft while one end of the shaft is provided with a coupling member corresponding to the coupling member mounted onto the godet shaft.
  • the invention provides a drawroll arrangement for draw-winding, spin-draw-winding and drawtwisting machines having a common rotatable shaft on which a godet is mounted in cantilevered fashion at one end and a rotor of a drive motor for driving the godet is mounted in cantilevered fashion at the other end.
  • the common shaft for directly transmitting the drive force from the motor to the godet is rotatably supported by two bearings within a housing situated between the godet and drive motor.
  • the drawing illustrates a cross-sectional view of a drawroll arrangement according to the invention.
  • the drawroll arrangement substantially comprises a heated'or unheated godet l constructed as a drawroll and a drive motor 2 with a rotor 3 and stator 4.
  • the godet l and the rotor 3 are mounted on a common shaft 5 which directly transmits a drive force from the motor 2 onto the godet 1.
  • the shaft 5 is provided with a journal 6, 7 of any suitable type at each end.
  • the journal 6 for the godet 1 can be provided as usual with a conical end portion facilitating the exchange of the godet 1 and the journal 7 is chosen to be of cylindrical nature with the rotor 3 press-fitted thereon.
  • the shaft 5 is rotatably supported by two bearings 8, 9 arranged between the two shaft journals 6, 7 or the godet 1 and the rotor 3 respectively in such manner that each of the two shaft journals 6, 7 extends outward from the bearings 8 and 9, respectively, in cantilevered fashion.
  • Both bearings 8, 9 are arranged in a pair of end walls of a common bearing housing 10.
  • the bearing housing 10 is provided with suitable mounting means 1 1 and is mounted on a machine frame 13, for example, by means of mounting screws 12, in order to be adjustably and detachably arranged.
  • the godet is mounted exteriorly of the housing 10.
  • the stator 4 of the drive motor 2 is also arranged in a separate motor housing 14, the outside of which is closed by a cover end plate 15 which is detachably mounted on the face side.
  • the stator 4 is secured to the housing 14.
  • the cover end plate 15 is void of any bearing for the shaft 5.
  • the other face side of the housing 14 opposite to the end plate cover 15 is provided with a mounting flange, mounting supports or, e.g. merely with bores parallel to the axis for detachably mounting the stator 4 and housing 14 exteriorly on the bearing housing 10 by means of screws 16.
  • the heating can be effected by a heating device 17 of any type as chosen, such as e.g. by a resistance heater or by an inductive heater.
  • a supply of preferably multiphase alternating current of controllable frequency is supplied by a suitable supply device 18, e.g. a controllable frequency invertor.
  • a suitable supply device 18 e.g. a controllable frequency invertor.
  • an inductive measuring value transducer is provided consisting of a rotating induction coil 19 mounted on the shaft 6 and of a stationary induction coil 20 mounted in the housing 10.
  • a further advantage is that, if heated godets 1 are used, the distance between the godet l and the drive motor 2 is enlarged. This considerably reduces the heating of the motor 2. Furthermore, no coupling members are needed between the motor shaft and godet shaft. As opposed to gear train arrangements, the rotational speeds of the drawroll of a whole machine for processing different material types and for different processing characteristics can be divided freely into groups or individually and can be controlled in groups or individually.
  • a further advantage of the drawroll arrangement is that the shaft diameter between the bearings 8, 9 and the distance between the bearings 8, 9 can be chosen as desired.
  • the shaft diameter between the bearings has been limited by the motor rotor.
  • These two values namely, shaft diameter between the bearings and the distance between the bearings, which are also determining factors of the critical rotational speed of the drawroll arrangement, allow the drawroll arrangement according to the invention to be laid out optimally in this respect.
  • the space between the bearings 8, 9 can be used for the arrangement of a measuring value transducer for transmitting a signal supplied e. g. by a temperature measuring gauge mounted within the drawroll.
  • a drawroll arrangement comprising a machine frame
  • a drive motor mounted at the opposite end of said shaft, said motor having a rotor secured on said opposite shaft end;
  • a bearing housing axially adjustably mounted on said machine frame and including a pair of end walls;
  • a drawroll arrangement comprising a machine frame
  • a bearing housing axially adjustably mounted on said machine frame and including a pair of end walls,
  • a drive motor within said motor housing having a rotor mounted on one of said journals of said shaft and a stator secured to said motor housing, and
