たホノモータの固定装置に関するものである。[Detailed description of the invention] This invention is a fixing device for a direct drive (DD) motor for a player, which is configured to fix the bearing directly to the cabinet to increase the rigidity and to increase the perpendicularity between the cabinet and the turntable. It is related to.

あり、吸振構造が得られないという欠点があつ
た。 Conventionally, this type of honomotor fixing device has a first
As shown in the figure, even if the motor yoke 1 is firmly tightened to the cabinet 3 with the screws 2, the bearing 4 and the yoke 1
There is deflection of the joints and motor yoke 1, etc.
It is impossible to increase the rigidity, and
Due to the caulking between the bearing 4 and the yoke 1 and the deflection of the yoke 1, the perpendicularity between the cabinet 3 and the turntable was poor. Furthermore, the yoke 1 vibrates due to the drive coil 5, but if a rubber sheet or the like is inserted between the cabinet 3 and the yoke 1 to suppress this vibration, the perpendicularity is significantly inhibited, making it impossible to obtain a vibration-absorbing structure. There was a drawback.

定装置を提供するものである。 This idea was made to eliminate the drawbacks of the conventional structure mentioned above, and by increasing the bearing rigidity, it not only improves the sound quality but also improves the perpendicularity between the cabinet and turntable, and improves the vibration-proofing effect of the motor yoke. The present invention provides a honomotor fixing device configured to raise the honomotor.

る。 Hereinafter, an embodiment according to this invention will be explained in detail based on FIG. 2. In the drawings, parts corresponding to those in the conventional example will be described with the same reference numerals. The bearing 4 is directly fixed to the cabinet 3 via the yoke 1 with a tightening nut 6. At this time, a sheet-shaped vibration isolating material 7 made of an elastic material is held between the yoke 1 and the cabinet 3.
従つて、軸受４はキヤビネツト３に垂直性を保
持した状態で強固に固定される。 Therefore, the bearing 4 is firmly fixed to the cabinet 3 while maintaining its verticality.

る。 As explained above, this idea extends the bearing of the direct drive motor, passes it through the cabinet, and tightens and fixes it with a tightening nut.If the dimensional accuracy of the hole in the cabinet is improved, the bearing can be easily connected to the cabinet. It can improve the verticality of the table, and it can also be used instead of small screws.
The motor and cabinet are firmly integrated, as they are fastened to the cabinet using bearings.
The mounting strength of the motor, which is a rotating part, and the turntable attached to the motor is increased, making parasitic vibrations due to rattling less likely to occur, and improving sound quality.
さらに、モータとキヤビネツトの間にシート状

振動がモータに伝達されるのを防止することがで
きる等の効果を有するものである。 Furthermore, by inserting a sheet-like vibration isolating material between the motor and the cabinet, it is possible to prevent the vibrations of the cabinet from being transmitted to the motor.
