Description

A spindle apparatus for driving a single unit of spinning device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a single spindle drive spindle device of a spinning machine for use in spinning machines such as ring spinning machines and ring twisters that independently drive spindles of each weight.

In recent years, in order to increase the number of spindles and increase the rotational speed of the spindles, instead of driving all the weights of the spindles with one motor, a motor for spindle driving is provided for each weight. The installed device is proposed.

As shown in FIG. 8, the single-wheel drive motor includes a rotor 33 and a stator 35, and the rotor 33 is interposed between bearings 31 and bearings on a bolster 30. And is rotatably fixed to an intermediate portion of the spindle 32 rotatably supported. In addition, the rotor 33 is disposed at a position corresponding to the stator 35 fixed inside the motor housing 34. The motor housing 34 is fixed to the upper outer peripheral surface of the housing 30a of the bolster 30. The support cylinder 38 is fixed to the bottom of the motor housing 34 via the rubber damper 37. Mounting of the bolster 30 to the spindle rail 36 is performed by inserting the support cylinder 38 into the mounting hole 36a of the spindle rail 36, and tightening with the nut which is not shown in figure. Moreover, the flange may be formed in the upper part of the housing 30a without providing the rubber damper 37, and the housing 30a may be inserted into the mounting hole 36a, and may be clamped and fastened with a flange and a nut.

Further, Japanese Patent Laid-Open No. 3-59120 discloses that a rubber metal element is sandwiched between an outer ring of a bearing of a spindle on which a rotor is fixed and an inner surface of the spindle housing. The motor housing is fixed to the spindle housing.

As shown in FIG. 8, in the configuration where the housing 30a and the motor housing 34 of the bolster 30 are not separated, a rubber damper 37 is provided between the motor housing 34 and the spindle rail 36. Even if installed, vibration of the spindle 32 is transmitted to the motor housing 34 through the bolster 30. As a result, fatigue breakdown of solder parts and the like of the electrical components provided in the motor housing 34 leads to deterioration of durability of the single weight drive motor. In addition, since the motor housing 34 and the housing 30a of the bolster 30 vibrate integrally, the vibration increases, and the load on the bearing 31 also increases.

On the other hand, in the configuration disclosed in Japanese Patent Laid-Open No. 3-59120, since the rubber metal element (buffer member) is provided between the spindle and the spindle housing, the vibration of the spindle is transmitted to the motor housing in a damped state. However, in the case where a shock absorbing member made of an elastic member such as rubber is mounted between two cylindrical members, it is difficult to firmly fix the shock absorbing member to both cylindrical members.

If the buffer member is to be firmly fixed using the adhesive, the adhesive member is applied to the surface of the two cylindrical members facing each other, and then the rubber-made buffer member is inserted into the gap of the cylindrical member to be fitted. However, when fitting, the adhesive is removed by the rubber so that the required adhesive strength cannot be obtained.

Therefore, in order to obtain the required adhesive strength, it is necessary to pour the rubber in the hot melt state while curing the adhesive while applying the adhesive to the surfaces of the two members. By the way, in this case, by the shrinkage which arises when the rubber of a molten state cools, a large residual stress exists in the state inside a rubber | gum. As a result, the desired dumping characteristics cannot be obtained. In addition, since the rubber is provided between the two members in a tensioned state, damage occurs when the rubber is broken.

There are two ways to resolve this nonconformity. First, in the state which formed the diameter of the outer part of two members largely, first, it flows in a hot melt state between two members, and hardens it. Thereafter, the diameter of the outer member is reduced so that residual stress does not occur in the rubber. Second, in the state where the diameter of the inner member is made small, first, the rubber is poured between the two members in a hot melt state and cured. Thereafter, the diameter of the inner member is enlarged to prevent residual stress from occurring in the rubber. However, both manufacturing methods are complex.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to provide a single spindle drive spindle device of a spinning machine which can prevent the vibration of the bolster from propagating directly to the motor housing, and which is easy to put the shock absorbing member. have.

1: drive spindle unit 2: bolster

4: spindle 5: motor

7: spindle rail 8: motor housing

13, 14, 23, 24: mounting portion 10, 20: buffer member

In order to achieve the above object, according to a main feature of the present invention, there is provided a single-weight drive spindle device of a spinning machine for driving a spindle by a motor, the spindle being rotatably supported integrally with the bolster, and the motor integrally with the spindle. In a spinning single-wheel drive spindle device having a rotor fixedly rotatable and a stator fixed in a motor housing supported by the spindle rail, between the housing of the bolster and the motor housing, a corresponding damping member having a damper action is provided. It is characterized in that it is installed to be fixed to both the housing or its mounting portion only on the surface extending in the horizontal direction.

According to such a structure, since there exists a shock absorbing member which has a damper action between the housing of a bolster and a motor housing, the vibration of a spindle propagates in the damped state instead of directly propagating to a motor housing. Therefore, fatigue breakdown of the solder parts and the like of the electrical components provided in the motor housing is suppressed, and durability of the single weight drive motor is improved. In addition, since the shock absorbing member is fixed to both the housings or their mounting portions only on the surface extending in the lateral direction, when only the adhesive is used, the adhesive is not removed and the necessary adhesive strength is secured. On the other hand, even when the rubber in a hot melt state is cured by flowing heat-melted rubber between both housings or its mounting portions disposed in the mold at the time of manufacture, residual stresses that adversely affect after cooling are prevented from occurring, so that desired dumping characteristics can be obtained.

In addition, the shock absorbing member is preferably fixed to both housings or their mounting portions by thermal fusion. Thereby, adhesive force becomes large compared with the case where a buffer member is stuck to both housings or its mounting part only by an adhesive agent. Herein, "heat fusion" in the present invention means bonding a material such as rubber, which is a buffer member, to a heat-melted state once, and bonding the heat-bonded surface to only the adhesive surface of the rubber once cured in addition to the cure bonding. It also includes post bonding for heating and melt bonding.

Furthermore, it is preferable that the single weight drive spindle device is provided with a separating buffer member for separating the spindle rail and the motor housing. In addition to propagation of the vibration of the spindle in the attenuated state in the motor housing, since there exists a separating buffer member for separating the spindle rail and the motor housing, the vibration of the spindle rail is prevented from propagating in the motor housing.

Further, the shock absorbing member can be formed in a ring shape and disposed in a state sandwiched between the mounting portion on the housing side of the bolster and the mounting portion on the motor housing side. This simplifies the mounting structure of the shock absorbing member and both housings.

In addition, both housings are configured to be mountable to the spindle rail via a support having an annular cushioning member, and the support includes a mounting portion for the spindle rail and a mounting portion for a motor housing integrally formed on an upper portion of the mounting portion. It is preferable that the shock absorbing member is fixed on the mounting portion for the motor housing, and the annular bolster mounting portion is fixed on the shock absorbing member. Thereby, the structure of the support body which mounts both housings to a spindle rail becomes simple.

Furthermore, both housings are configured to be mountable to the spindle rail via a support having an annular cushioning member, the support being arranged on the outside by inserting a mounting portion for the spindle rail and a cushioning member on top of the mounting portion. It is preferable that the mounting portion for the motor housing and the annular bolster mounting portion arranged inside are provided, and the shock absorbing member also serves as a separating shock absorbing member. Since the number of component parts of this structure is small compared with the structure which uses a buffer member and a separating buffer member for another component, manufacture becomes simple.

Further, the bolster mounting portion may be formed integrally with the housing of the bolster. Moreover, it is also preferable to comprise a buffer member by clamping a boundary plate between a plurality of viscoelastic bodies. In this case, the plurality of viscoelastic bodies may be formed of different materials, or the layers of the plurality of viscoelastic bodies may be connected to each other on the inner circumferential side or the outer circumferential side.

(Example 1)

Hereinafter, a first embodiment of the present invention will be described with reference to FIG. The single weight drive spindle device 1 includes a motor 5 for driving the spindle 4, which is supported by the bolster 2 so as to be rotatable through a radial bearing 3. . The motor 5 has a rotor 6 and a stator 9, the rotor 6 being fixedly rotatably integrally with the spindle 4, and the stator 9 with the spindle rail 7. It is fixed in the supported motor housing 8.

The motor housing 8 is comprised so that attachment to the spindle rail 7 via the support body 11 provided with the shock absorbing member 10 which has a damper effect | action is carried out. The shock absorbing member 10 is formed in ring shape by hardening rubber. The support 11 includes a mounting portion 12 for the spindle rail 7, a mounting portion 13 for the motor housing integrally formed on the upper portion of the mounting portion 12, a buffer member 10, and an annular bolster mounting portion. (14) is provided. The motor housing mounting part 13 is formed in the cylindrical shape which has the flange 13a in the lower part. The inner diameter of the cylindrical portion of the motor housing mounting portion 13 is formed larger than the outer diameter of the shock absorbing member 10. The inner diameter of the shock absorbing member 10 is formed equal to or larger than the inner diameter of the mounting part 12 so that the housing 2a and the shock absorbing member 10 do not contact. The shock absorbing member 10 is fixed on the inner side of the mounting portion 13 for the motor housing or on the flange 13a so as to have the same center of gravity as the mounting portion 12. And the bolster attaching part 14 is fixed to the buffer member 10. As shown in FIG. That is, the shock absorbing member 10 is fitted between the mounting portion 13 and the bolster mounting portion 14 for the motor housing and is fixed to both mounting portions 13 and 14 only on the surface in which the shock absorbing member 10 extends in the horizontal direction. It is arranged in a state. In addition, the bolster mounting part 14 is formed with the outer diameter equal to the buffer member 10, and the inner diameter is smaller than the buffer member 10. FIG.

The motor housing 8 is composed of a cylindrical body 8a and a lid 8b covering the upper opening. On the inner surface of the main body 8a, a step portion for positioning at the time of attachment of the stator 9 is formed. The stator 9 is attached to the upper side of the motor housing 8 with its lower end engaging with the upper side than the stepped portion and the upper end engaging with the lower end of the lid 8b.

The lower part of the main body 8a is fitted and fixed to the outer peripheral surface of the mounting portion 13 for motor housing. The main body 8a is fixed to the motor housing mounting portion 13 so that its lower end is located above the lower end of the flange 13a of the motor housing mounting portion 13. Therefore, the support body 11 is attached to the spindle rail 7, and the main body 8a does not contact the spindle rail 7. The support 11 is attached to the spindle rail 7 by fitting the mounting part 12 to the mounting hole 7a formed in the spindle rail 7.

The housing 2a of the bolster 2 is formed in a cylindrical shape with a bottom, and its upper outer circumference is fitted and fixed to the bolster mounting portion 14. In addition, the housing 2a is attached to the bolster mounting portion 14 of the support 11 so as to penetrate the support 11 without being in contact with the mounting portion 12. Moreover, inside the bolster 2, the radial bearing 3 is arrange | positioned at two places of upper and lower sides, and the spindle bearing 15 which contacts the lower end of the spindle 4 at the lower part is arrange | positioned.

When manufacturing the support body 11, each mounting part 12, 13, 14 is arrange | positioned in the predetermined position in a metal mold | die, and between the inner peripheral surface of the motor housing mounting part 13, and the outer peripheral surface of the bolster mounting part 14, respectively. The spacer which prevents rubber from invading is arrange | positioned. At this time, an adhesive for rubber is applied to a portion to be fixed to the shock absorbing member 10 of the mounting portion 13 and the bolster mounting portion 14 for the motor housing. In that state, the rubber which mixed this mold and sulfur etc. is pressurized and heated, the rubber of a hot melt state is pressed in a metal mold | die, and hardened | cured. And after cooling, the molded support body 11 is removed from the inside of a metal mold | die. The molten rubber is firmly mounted (adhered) only to the portion to which the adhesive is applied. That is, the buffer member 10 is fixed to both mounting portions 13 and 14 only on the surface extending in the horizontal direction. The rubber shrinks during cooling, but the residual stress is reduced because the mounting portion 13 and the bolster mounting portion 14 for the motor housing can move in the axial direction of the support 11.

When assembling the single weight drive spindle device 1, the housing 2a of the bolster 2 is press-fitted to the bolster mounting portion 14 of the support 11 manufactured as described above, and the mounting portion for the motor housing ( 13, the main body 8a of the motor housing 8 is press-fitted.

The following describes the operation of the single weight drive spindle device 1 configured as described above.

When attaching the single weight drive spindle device 1 to the spindle rail 7, the mounting portion 12 of the support 11 is fixed to the mounting hole 7a of the spindle rail. Moreover, you may form a screw part in the mounting part 12, and may be fastened and fastened with a nut.

When the motor 5 is driven during the operation of the spinning machine, the spindle 4 is rotated. The thread is wound on a bobbin (not shown) mounted to the spindle 4 by the rotation of the spindle 4. Vibration according to the rotation of the spindle 4 propagates to the bolster 2 through the radial bearing 3, the vibration of the bolster 2 is then propagated to the motor housing 8 via the support 11. do. Since the shock absorbing member 10 is interposed between the mounting portion 13 and the bolster mounting portion 14 for the motor housing constituting the support 11, the vibration of the bolster 2 is large due to the damper action of the shock absorbing member 10. Attenuated and propagated to the motor housing 8. Therefore, the vibration acting on the solder part of the electrical component provided in the motor housing 8 becomes extremely small. In addition, large vibration of the housing 2a of the motor housing 8 and the bolster 2 is suppressed integrally, and the burden on the radial bearing 3 becomes small.

In this first embodiment, the following effects are obtained.

(1) Since a shock absorbing member 10 having a damper action is provided between the housing 2a of the bolster 2 and the motor housing 8, vibration of the spindle 4 is transmitted from the bolster 2 to the motor housing ( It propagates in attenuated state, not directly to 8). Therefore, fatigue breakdown of solder parts and the like of the electrical components provided in the motor housing 8 is suppressed. As a result, the durability of the motor 5 is improved.

(2) The shock absorbing member 10 is fixed to the mounting portion 13 and the bolster mounting portion 14 for the motor housing only on the surface extending in the horizontal direction. Therefore, even when the rubber in the hot-melt state is pressed and cured between the motor housing mounting portion 13 and the bolster mounting portion 14 disposed in the mold at the time of manufacture, residual stresses that adversely affect after cooling are prevented from occurring. . As a result, the buffer member 10 can obtain desired damping characteristics. Moreover, even when only an adhesive agent is used, since an adhesive agent is not removed to rubber at the time of an adhesion | attachment operation, adhesive strength is not impaired.

(3) Since the shock absorbing member 10 is fixed to both mounting parts 13 and 14 by heat fusion, the adhesive force is lower than that of the case where the shock absorbing member 10 is fixed to both mounting parts 13 and 14 only by an adhesive. Grows Therefore, it becomes easy to ensure the required adhesive strength.

(4) The shock absorbing member 10 is formed in a ring shape, and is provided in a state sandwiched between the motor housing mounting portion 13 and the bolster mounting portion 14. Therefore, the attachment structure of the shock absorbing member 10 and both housings 8 and 2a becomes simple.

(5) Both housings 8, 2a are configured to be mountable to spindle rail 7 via support 11 with annular cushioning member 10, and support 11 is spindle rail 7. ), A mounting portion 13 for the motor housing integrally formed on the upper portion of the mounting portion 12, and an annular bolster fixed to the mounting portion 13 via a buffer member 10. A mounting portion 14 is provided. Therefore, the structure of the support body 11 which mounts both the housings 8 and 2a to the spindle rail 7 becomes simple.

(6) The support body 11 which mounts both the housings 8 and 2a to the spindle rail 7 is manufactured separately from both the housings 8 and 2a. Both housings 8 and 2a are attached to the support 11. Therefore, as compared with the configuration in which the housings 8 and 2a are integrally formed with both the mounting portions 13 and 14, the mold at the time of manufacture for fixing the buffer member 10 by heat fusion between the two mounting portions 13 and 14. Can be made small. Therefore, the manufacturing cost is lowered.

(Example 2)

Next, a second embodiment will be described with reference to FIG. In this embodiment, the single weight drive spindle device 1 differs greatly from the above embodiment in that the spindle rail 7 and the motor housing 8 are separated by a separating buffer member. The same parts as in the above embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

In the support body 11, the mounting part 22 with respect to the spindle rail 7, and the mounting part for motor housings 23 are formed separately. And the shock absorbing member 20 is arrange | positioned between both mounting parts 22 and 23, and the shock absorbing member 20 is being fixed on the flange 22a of the mounting part 22. As shown in FIG. The motor housing mounting part 23 is formed in a round ring shape, and the bolster mounting part 24 is formed in the cylindrical shape which has the flange 24a in the lower part. And the motor housing mounting part 23 is arrange | positioned at the outer side with the shock absorbing member 20, and the bolster mounting part 24 is arrange | positioned inside, respectively. That is, the shock absorbing member 20 is a shock absorbing member which attenuates the propagation of the vibration from the bolster mounting part 24 to the mounting part 23 for motor housings, and the separating shock absorbing member which isolate | separates the spindle rail 7 and the motor housing 8, respectively. Is also serving.

The mounting portion 23 for the motor housing is fixed to the shock absorbing member 20 on its lower surface, and the bolster mounting part 24 is fixed to the shock absorbing member 20 on the upper and lower surfaces of the flange 24a. . That is, both mounting parts 23 and 24 are fixed to only the surface extended to the shock absorbing member 20 in the horizontal direction.

The motor housing 8 is attached to the support 11 by fitting and fixing the lower part of the main body 8a to the outer peripheral surface of the mounting portion 23 for motor housing.

When manufacturing the support body 11, each mounting part 22, 23, 24 is arrange | positioned in the predetermined position in a metal mold | die. At this time, a portion to be fixed to the shock absorbing member 20 of the mounting portion 23 and the bolster mounting portion 24 for the motor housing, that is, the inner side of the lower surface of the mounting portion 23 and the flange 24a of the bolster mounting portion 24 Apply rubber adhesives on both the upper and lower sides of the In that state, the rubber which mixed this metal mold | die and sulfur etc. is pressurized and heated, the rubber of a hot melt state is pressed in a metal mold | die, and it hardens. Then, the cooled support 11 is removed from the mold after cooling. The molten rubber is firmly mounted (adhered) only to the portion to which the adhesive is applied. Therefore, rubber is not stuck to the inner circumferential surface of the mounting portion 23 for motor housing, the outer circumferential surface of the cylindrical portion of the bolster mounting portion 24 and the outer circumferential surface of the flange 24a. As a result, even if the rubber shrinks during cooling, both the mounting portions 23 and 24 do not restrict the shrinkage of the rubber in the axial direction of the support 11. Therefore, similarly to the first embodiment described above, the residual stress of the buffer member 20 also becomes small in this second embodiment.

Therefore, in this second embodiment, in addition to having the effects of (1) to (4) and (6) in the above embodiment, the following effects are obtained.

(7) Since there is a separating buffer member for separating the spindle rail 7 and the motor housing 8, the vibration of the spindle rail 7 is prevented from propagating to the motor housing 8. As a result, the vibration of the spinning machine base is prevented from propagating to the motor housing 8 through the spindle rail 7.

(8) The buffer member 20 also serves as a separating buffer member. Therefore, compared with the structure which makes the buffer member and isolation | separation buffer member interposed between the bolster 2 and the motor housing 8 into other components, the number of component parts becomes small, and as a result, manufacture becomes simple.

(Example 3)

Next, a third embodiment will be described with reference to FIG. In this third embodiment, the structure of the support body 11 in the second embodiment is configured such that the motor housing mounting portion 23 is formed into a cylindrical shape having a flange 23a at the lower portion thereof, and the bolster mounting portion 24 is rounded. It is formed in a ring shape. That is, it was comprised so that the shape of both mounting parts 23 and 24 may be replaced. Also with this structure, the same effects as in the second embodiment can be obtained.

(Example 4)

Next, a fourth embodiment will be described with reference to FIG. In this fourth embodiment, the configuration of the shock absorbing member is only different from that of the shock absorbing member of the first embodiment, and other portions are the same as in the first embodiment. Therefore, the same parts as in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

The buffer member 100 has a structure in which a boundary plate 102 is sandwiched between a plurality of viscoelastic bodies 101. In this embodiment, the viscoelastic bodies 101 are provided in two layers. The viscoelastic bodies 101 and the boundary plate 102 are formed in an annular flat plate shape and are arranged horizontally. The boundary plate 102 is formed of a rigid body (for example, steel sheet). The viscoelastic body 101 is formed of hardened rubber. In addition, the buffer member 100 presses and heats the rubber and rubber in which the sulfur is mixed, and the mold in a state where the boundary plate 102 is disposed at a predetermined position in the mold, for example, to mold the rubber in a hot melt state. It is manufactured by pressing in and hardening | curing in a inside.

In this manner, the buffer member 100 is provided with a viscoelastic body 101 having a plurality of layers (two layers in this embodiment) by sandwiching the boundary plate 14. Therefore, the damper effect | action by this buffer member 100 becomes more excellent than the 1st Example which formed the buffer member by the viscoelastic body of one layer. In addition, the boundary plate 102 existing between the viscoelastic bodies 101 functions as a dummy mass, that is, the boundary plate 102 vibrates instead of the spindle 4, so that the damping constant in the shear direction increases. . As a result, even when the spinning machine is operated at high speed, the vibration of the spindle 4 is effectively attenuated, and the increase in the vibration of the spindle 4 is suppressed. Therefore, the burden on the radial bearing 3 becomes small.

In this fourth embodiment, the following effects are obtained.

(9) The buffer member 100 is comprised so that the boundary plate 102 may be constricted between the viscoelastic body 101 of several layers. Therefore, when the volume of the shock absorbing member 100 is the same, a damping constant becomes large compared with the structure which used the viscoelastic body of one layer, and it is suppressed that the vibration of the spindle 4 becomes large even at high speed operation.

(10) Since the shock absorbing member 100 is used in a state where a plurality of viscoelastic bodies 101 are arranged horizontally, the spring constant in the compression direction while maintaining a constant spring constant in the shear direction of the shock absorbing member 100. Can be increased.

(11) Since the viscoelastic body 101 and the boundary plate 102 are fixed to each other by thermal fusion, it is possible to increase the adhesive force and to secure necessary adhesive strength as compared with the case where both are fixed with an adhesive. It becomes easy.

(Example 5)

Next, a fifth embodiment will be described with reference to FIG.

In this fifth embodiment, the shock absorbing member 100 has a configuration in which the boundary plate 102 is squeezed between two viscoelastic bodies similarly to the fourth embodiment, but the plurality of viscoelastic bodies 101a and 101b Each is composed of different materials. In this case, adjusting the vibration characteristics and the dimensions of the shock absorbing member 100 to a desired value required for the spindle can be performed relatively easily without increasing the cost. In addition, the "other material" said here does not only mean that a kind of rubber | gum or an elastomer is different, but is included in a "other material" when the degree of hardening differs even in the same rubber | gum.

(Example 6)

Next, a sixth embodiment will be described with reference to FIG.

In the sixth embodiment, the shock absorbing member 100 is configured such that the boundary plate 102 is squeezed between a plurality of layers of viscoelastic bodies 101 similarly to the fourth embodiment. The viscoelastic body 101 which comprises is made into three layers. In addition, the viscoelastic body 101 may be four or more layers. In this case, not only the structure which makes all layers the same material, but each layer may be made of a different material, or may be made the structure which makes two layers the same material.

(Example 7)

Next, a seventh embodiment will be described with reference to FIG.

In this seventh embodiment, the shock absorbing member 110 is configured such that the boundary plate 112 is squeezed between the viscoelastic bodies 111 of a plurality of layers, as in the previous embodiment. Here, the plurality of viscoelastic bodies 111 are formed in a ring shape, and as shown in the drawings, the viscoelastic bodies 111 are configured to be connected to each other on the outer circumferential side. In addition, each viscoelastic body 111 may have a structure connected to each other in the inner peripheral side. In this case, when manufacturing the buffer member 110 by insert molding, the structure of a metal mold | die becomes simple and manufacturing cost can be made low.

In the case where the buffer member is formed of a plurality of layers, the viscoelastic bodies 101 and 111 and the boundary plates 102 and 112 constituting the buffer members 100 and 110 may be adhered to each other with an adhesive.

The boundary plates 102 and 112 are not limited to metal plates such as steel sheets or aluminum plates, but may be resin plates or ceramic plates. Moreover, you may change suitably the thickness of a boundary plate.

In addition, an Example is not limited to the above, For example, you may specify as follows.

(a) The buffer member interposed between the bolster 2 and the motor housing 8 and the separating buffer member may be other components. For example, in the first embodiment, a separating buffer member may be interposed between the flange 13a of the mounting portion 13 for the motor housing and the spindle rail 7. In addition, the mounting part 12 of the support body 11 and the mounting part for motor housings 13 may be formed separately, and the separating buffer member may be interposed between them.

(b) The surface on which the shock absorbing members 10 and 20 are fixed to both housings 8 and 2a or its mounting portions 13, 23, 14 and 24 is not limited to the state perpendicular to the axial direction of the spindle 4. It may be formed so as to extend in an obliquely intersecting direction. That is, the surface extending in the horizontal direction includes a surface which is slightly inclined, not limited to the horizontal surface.

(c) The motor housing 8 and the mounting portions 13 and 23 for the motor housing may be integrally formed. In addition, the housing 2a of the bolster 2 and the bolster mounting parts 14 and 24 may be formed integrally. That is, substantially removing the mounting portion 13, 23 for the motor housing or the bolster mounting portions 14, 24, the fixing member 10, 20 is fixed between the housing 2a of the bolster 2 and the motor housing 8 Install in the correct state. Here, in the case where the shock absorbing members 10 and 20 are installed between the two housings 2a and 8 by heat fusion, the mold used for manufacturing increases, but the effort for mounting the single weight drive spindle device 1 is reduced. .

(d) The housing 2a of the bolster 2 and the bolster mounting parts 14 and 24 are integrally formed, and the motor housing 8 and the motor housing mounting parts 13 and 23 are formed separately. In this case, the effort of mounting the single weight drive spindle device 1 is simplified, and the motor 5 can be detached in a state where the bolster 2 is fixed to the spindle rail 7, so that the maintenance is easy.

(e) The shock absorbing member 10 is not limited to a ring shape, and a plurality of shock absorbing members may be provided so that the whole of the shock absorbing member may be substantially annular.
