Definitions

  • the present invention relates to a spindle device for driving a single spindle in a spinning machine which is used to drive spindles separately in a spinning machine such as a ring spinning frame or a ring twisting machine.
  • Some recently proposed spinning frames have instead of only one motor for driving all the spindles in the spinning frame, a plurality of spindle-driving motors so that each spindle can have its own motor. This is aimed at making it possible to set a large number of spindles in the spinning frame, or to increase the rotational speed of the spindles.
  • the motor for driving a single spindle is provided with a rotor 33 and a stator 35.
  • the rotor 33 is fixed to the middle of a spindle 32 in a manner that allows the rotor 33 to rotate together with the spindle 32 that is,rotatably supported in a bolster 30 through a bearing 31.
  • the rotor 33 is positioned relative to the stator 35, which is fixed inside a motor housing 34.
  • the motor housing 34 is fixed to the upper outer peripheral surface of a housing 30a of the bolster 30.
  • the motor housing 34 has on its bottom a supporting tube 38 fixed thereto through a rubber damper 37.
  • the bolster 30 is fitted to a spindle rail 36 by inserting the supporting tube 38 into an insertion hole 36a of the spindle rail 36 and fastening it with a nut (not-shown).
  • the rubber damper 37 may be replaced by a flange formed in an upper part of the housing 30a. In this case, the housing 30a is inserted into the insertion hole 36a and then fastened and fixed by the flange and a nut.
  • the structure disclosed in Japanese Patent Application Laid-open No. 3-59120 transfers the vibration of the spindle to the motor housing with the vibration attenuated, owing to the rubber metal element (buffer member) provided between the spindle and the spindle housing.
  • the buffer member made of an elastic member such as rubber is to be attached between two cylindrical members, there are difficulties in firmly fixing the buffer member to both of the two cylindrical members.
  • One method is to pour the heat melted rubber into the gap between the two cylindrical members with the outer one having a larger diameter and to sulfurize the rubber simultaneously. The diameter of the outer member is then reduced so as not to leave any residual stress in the rubber.
  • the other method is to pour the heat melted rubber in the gap between the two cylindrical members with the inner one having a smaller diameter and to sulfurize the rubber simultaneously. The diameter of the inner member is then increased so as not to leave any residual stress in the rubber.
  • both methods are complicated.
  • the present invention has been made in view of the above problems, and an object of the present invention is to therefore provide a spindle device for driving a single spindle in a spinning machine which can prevent the vibration of a bolster from being transferred directly to a motor housing and which is easy to incorporate a buffer member into.
  • the main aspect of the present invention provides a spindle device for driving a single spindle in a spinning machine, comprising a spindle and a motor that drives the spindle, the spindle being rotatably supported in a bolster, the motor having a rotor and a stator, the rotor being fixed to the spindle in a manner that allows the rotor to rotate together with the spindle, the stator being fixed inside a motor housing that is supported on a spindle rail, characterized in that a buffer member having a damper effect is provided between a housing of the bolster and the motor housing such that the buffer member is fixed to the housings, or to their respective attaching portions, only on its laterally extending faces.
  • This structure transfers the vibration of the spindle to the motor housing not directly but attenuated, for the buffer member having a damper effect is provided between the housing of the bolster and the motor housing. Accordingly, breakage from fatigue of solder or the like of electric components provided in the motor housing can be controlled, thereby improving the durability of the motor for driving a single spindle.
  • the buffering member which is fixed to the housings, or to their respective attaching portions, only on its laterally extending faces, does not scrape any adhesive off to provide the necessary degree of adhesion when the adhesive is used alone.
  • the present invention is advantageous also in the case where heat melted rubber is poured into the gap between the housings, or between their attaching portions, and placed in a mold to sulfurize the rubber upon manufacturing.
  • a specific advantage given by the invention in this case is obtainment of a desired damping characteristic because the invention can prevent residual stress that could be generated when the rubber is cooled and affect the device.
  • the buffer member is fixed to the housings, or to their respective attaching portions, preferably by thermal fusion. This enhances the degree of adhesion as compared with the case where the buffer member is fixed to the housings, or to their respective attaching portions, by an adhesive alone.
  • thermal fusion herein means bonding that involves heat melting a material of the buffer member, such as rubber, once. Thermal fusion includes, in addition to sulfurizing bonding, post-bonding in which rubber is sulfurized in advance and only the bonding face of the rubber is heat melted to be bonded.
  • the spindle device for driving a single spindle in a spinning machine further comprises a separating buffer member for separating the spindle rail and the motor housing from each other.
  • the spindle device that has the separating buffer member for separating the spindle rail and the motor housing from each other can prevent the spindle rail from transferring its vibration to the motor housing.
  • the buffer member may be shaped into a ring and placed such that it is sandwiched between the attaching portion for the housing of the bolster and the attaching portion for the motor housing. This simplifies the structure for attaching the buffer member to the housings.
  • the housings are attachable to the spindle rail through a supporting body provided with the ring-shaped buffer member; the supporting body is provided with a spindle rail attaching portion for attaching the spindle rail and a motor housing attaching portion integrally formed on top of the spindle rail attaching portion; the buffer member is fixed on the motor housing attaching portion; and a bolster attaching portion that is shaped into a ring and is fixed to the top face of the buffer member.
  • the housings are attachable to the spindle rail through a supporting body provided with the ring-shaped buffer member; the supporting body is provided with a spindle rail attaching portion for attaching the spindle rail, a motor housing attaching portion that is shaped into a ring and placed on the spindle rail attaching portion outside of the buffer member, and a bolster attaching portion that is shaped into a ring and placed inside of the buffer member; and the buffer member serves also as the separating buffer member.
  • the components in this structure are smaller in number than the case where the buffer member and the separating buffer member are separate components, thereby simplifying the manufacture.
  • the bolster attaching portion may be formed so as to be integrated with the housing of the bolster. It is also desirable to form the buffer member from layers of viscous elastic bodies a partitioning plate sandwiched between each layers. In this case, the plural viscous elastic bodies may be formed of different materials. Also, the plural viscous elastic bodies may form layers coupled with one another on their inner periphery side or outer periphery side.
  • a spindle device 1 for driving a single spindle is provided with a motor 5 for driving a spindle 4.
  • the spindle 4 is rotatably supported in a bolster 2 through radial bearings 3 .
  • the motor 5 is provided with a rotor 6 and a stator 9.
  • the rotor 6 is fixed to the spindle 4 in a manner that allows the rotor 6 to rotate together with the spindle 4.
  • the stator 9 is fixed inside a motor housing 8 that is supported on a spindle rail 7.
  • the motor housing 8 is attachable to the spindle rail 7 through a supporting body 11 that is provided with a buffer member 10 having a damper effect.
  • the buffer member 10 is formed of sulfurized rubber and shaped into a ring.
  • the supporting body 11 is provided with a spindle rail attaching portion 12 for attaching the spindle rail 7, a motor housing attaching portion 13 integrally formed on top of the spindle rail attaching portion 12, the buffer member 10, and a bolster attaching portion 14 that is shaped into a ring.
  • the motor housing attaching portion 13 is formed into a cylinder having a flange 13a on its lower part. The inner diameter of the cylindrical part of the motor housing attaching portion 13 is larger than the outer diameter of the buffer member 10.
  • the inner diameter of the buffer member 10 is the same as or larger than the inner diameter of the spindle rail attaching portion 12 so that the buffer member 10 does not contact with a housing 2a of the bolster 2.
  • the buffer member 10 is fixed on the flange 13a inside the motor housing attaching portion 13 such that the buffer member 10 is coaxial with the spindle rail attaching portion 12.
  • the bolster attaching portion 14 is fixed to the top face of the buffer member 10. In other words, the buffer member 10 is placed such that it is sandwiched between the motor housing attaching portion 13 and the bolster attaching portion 14 and it is fixed to the attaching portions 13 and 14 only on its laterally extending faces.
  • the bolster attaching portion 14 has the same outer diameter as the buffer member 10 and has an inner diameter smaller than that of the buffer member 10.
  • the motor housing 8 is comprised of a cylindrical main body 8a and a cover 8b for covering the upper opening thereof.
  • the inner surface of the main body 8a has a stepped portion for positioning the stator 9 when the stator 9 is to be incorporated.
  • the stator 9 is incorporated with an inner upper part of the motor housing 8 with its lower end engaging with the stepped portion and its upper end engaging with the lower end of the cover 8b.
  • the lower part of the main body 8a is engagingly fitted to the outer peripheral surface of the motor housing attaching portion 13.
  • the main body 8a is fixed to the motor housing attaching portion 13a such that the lower end of the main body is positioned above the lower end of the flange 13a of the motor housing attaching portion 13. Therefore the main body 8a is not in contact with the spindle rail 7 when the supporting body 11 is attached to the spindle rail 7.
  • the supporting body 11 is attached to the spindle rail 7 by fitting the spindle rail attaching portion 12 into an insertion hole 7a formed in the spindle rail 7.
  • the bolster 2 has a housing 2a that is formed into a bottomed cylinder.
  • the housing 2a is engagingly fitted to the bolster attaching portion 14 on its upper outer periphery.
  • the housing 2a is attached to the bolster attaching portion 14 of the supporting body 11 in a manner that makes the housing to pierce through the supporting body 11 without touching the spindle rail attaching portion 12.
  • the radial bearings 3 are placed inside the bolster 2 with one bearing positioned in an upper part of the bolster 2 and another bearing positioned in a lower part thereof.
  • a thrust bearing 15 abutting against the bottom of the spindle 4 is placed in an inner lower part of the bolster 2.
  • the attaching portions 12, 13 and 14 are placed in their respective positions in a mold, and a spacer is arranged to prevent rubber from entering into the gap between the inner peripheral surface of the motor housing attaching portion 13 and the outer peripheral surface of the bolster attaching portion 14.
  • An adhesive for rubber is then applied to the surfaces of the motor housing attaching portion 13 and the bolster attaching portion 14 to which the buffer member 10 is to be fixed.
  • the mold and rubber having sulfur or other sulfurizing substances mixed therein are pressurized and heated, and the heat melted rubber is poured into the mold with pressure to thereby sulfurize the rubber. After the rubber is cooled, the molded supporting body 11 is removed from the mold.
  • the melted rubber is firmly fixed (adhered) only to the surfaces that have been coated with the adhesive. That is, the buffer member 10 is fixed to the attaching portions 13 and 14 only on its laterally extending faces. The rubber shrinks when it is cooled, but only a little residual stress is generated because the motor housing attaching portion 13 and the bolster attaching portion 14 can move in the axial direction of the supporting body 11.
  • the housing 2a of the bolster 2 is fixed by press fitting to the bolster attaching portion 14 of the supporting body 11 manufactured as above.
  • the main body 8a of the motor housing 8 is fixed by press fitting to the motor housing attaching portion 13.
  • the spindle device 1 for driving a single spindle is incorporated with the spindle rail 7 by engagingly fitting the spindle rail attaching portion 12 of the supporting body 11 to the insertion hole 7a of the spindle rail 7.
  • the spindle rail attaching portion 12 may have a threaded portion so that it can be fixed to the spindle rail by fastening a nut.
  • the motor 5 is driven to rotate the spindle 4 while a spinning machine is running. With the rotation of the spindle 4 , thread is wound onto a not-shown bobbin mounted to the spindle 4.
  • the vibration accompanying the rotation of the spindle 4 is transferred through the radial bearings 3 to the bolster 2, and the vibration of the bolster 2 is then transferred through the supporting body 11 to the motor housing 8.
  • the motor housing attaching portion 13 and the bolster attaching portion 14 that constitute the supporting body 11 have the buffer member 10 interposed therebetween, so that the vibration of the bolster 2 is transferred to the motor housing 8 after the vibration is largely attenuated by the damper effect of the buffer member 10.
  • Embodiment 2 will be described next with reference to Fig. 2.
  • a spindle device 1 for driving a single spindle of this embodiment has a separating buffer member that separates the spindle rail 7 and the motor housing 8 from each other.
  • the same components as those in Embodiment 1 are denoted by the same reference symbols to omit detailed descriptions thereof.
  • a spindle rail attaching portion 22 for attaching the spindle rail 7 is formed separately from a motor housing attaching portion 23.
  • a buffer member 20 is placed between the attaching portions 22 and 23, and is fixed on a flange 22a of the spindle rail attaching portion 22.
  • the motor housing attaching portion 23 is shaped into a ring.
  • a bolster attaching portion 24 is formed into a cylinder that has on its lower part a flange 24a.
  • the motor housing attaching portion 23 is placed outside of the buffer member 20 and the bolster attaching portion 24 is placed inside of the buffer member 20. That is, the buffer member 20 serves as the buffer member for attenuating the vibration transferred to the motor housing attaching portion 23 from the bolster attaching portion 24 and also as the separating buffer member for separating the motor housing 8 and the spindle rail 7 from each other.
  • the motor housing attaching portion 23 is fixed to the buffer member 20 on its bottom face.
  • the bolster attaching portion 24 is fixed to the buffer member 20 on the top and bottom faces of the flange 24a. In short, the attaching portions 23 and 24 are fixed to the buffer member 20 only on their laterally extending faces.
  • the motor housing 8 is attached to the supporting body 11 by engagingly fitting a lower part of the main body 8a to the outer peripheral surface of the motor housing attaching portion 23.
  • the attaching portions 22, 23 and 24 are placed in their respective positions in a mold.
  • An adhesive for rubber is then applied to the surfaces of the motor housing attaching portion 23 and the bolster attaching portion 24 to which the buffer member 20 is to be fixed.
  • the surfaces to be coated with the adhesive are a lower inside surface of the attaching portion 23 and the top and bottom faces of the flange 24a of the bolster attaching portion 24.
  • the mold and rubber having sulfur or other sulfurizing substances mixed therein are pressurized and heated, and the heat melted rubber is poured into the mold under pressure to thereby sulfurize the rubber. After the rubber is cooled, the molded supporting body 11 is removed from the mold.
  • Embodiment 2 is thus successful in reducing the residual stress in the buffer member 20 as in Embodiment 1 described above.
  • Embodiment 2 can provide the following effects in addition to the effects (1) to (4) and (6) of Embodiment 1.
  • Embodiment 3 will be described next with reference to Fig. 3.

  • Embodiment 4 will be described next with reference to Fig. 4.

  • the buffer member 100 has layers (two layers, in this embodiment) of viscous elastic bodies 101 sandwiching a partitioning plate between each layer.
  • the buffer member 100 has a superior damper effect compared to Embodiment 1 in which a single layer viscous elastic body is used to form the buffer member.
  • the partitioning plate 102 interposed between the viscous elastic bodies 101 functions as a dummy mass.
  • the partitioning plate 102 vibrates instead of the spindle 4 to thereby increase the attenuation constant in the shearing direction.
  • the vibration of the spindle 4 can effectively be attenuated even when the spinning machine is operated at high speed, thereby keeping the vibration of the spindle 4 from multiplying. This makes the load of the bearings 3 smaller.
  • Embodiment 4 provides the following effects.
