本発明は主にＯＡ種機器使用される低振動のステッピン
グモータに関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a low-vibration stepping motor mainly used in office automation equipment.
従来の技術
近年、ＯＡ種機器のステッピングモータの使用が増大し
ており、これにともないモータの取付精度の向上や振動
、騒音を低減することが望まれている。BACKGROUND OF THE INVENTION In recent years, the use of stepping motors in office automation equipment has increased, and along with this, it has been desired to improve the mounting accuracy of motors and to reduce vibration and noise.
以下、図面を謬照しながら従来の技術について説明する
。The conventional technology will be described below with reference to the drawings.
第２図は従来のステッピングモータの半断面図である。FIG. 2 is a half-sectional view of a conventional stepping motor.

て行われる。In the figure, 1 is the stepping motor body or the outer frame of the main body, 2 is the motor mounting plate, and 1 is the stepping motor body 1.
It is fixed to the end face by spot welding or rivets. Although the inside of the motor is largely omitted, it includes a stator 4, a rotor 6, and a shaft 6. The stator 4 is fixed to the outer frame 1 of the motor body, and a rotor 5 is rotatably attached to the center of the stator 4 with a shaft 6 held by a bearing. The motor is attached to the equipment by fixing the mounting plate 2 to the chassis (not shown) of the equipment with screws or the like.

という問題点もあった。Problems to be Solved by the Invention In the above-mentioned conventional configuration, when spot welding the mounting plate 2 and the stepping motor main body 1, projection processing is performed in advance at the welding location, but due to processing accuracy problems, the contact surface of the projection is uneven. In some cases, the plane of the mounting plate 2 may be distorted during spot welding, and in this case, the motor cannot be correctly mounted to the equipment. Furthermore, stepping motors are motors that inherently produce high levels of vibration and noise, and there is also a problem in that vibrations and noise are directly transmitted to the equipment through the mounting plate 2 that is rigidly coupled.

て接着固定されている。Means for Solving the Problems In the stepping motor of the present invention, the motor body is adhesively fixed to a mounting plate for mounting the motor to a device via a rubber elastic body.

うにする。Function: Since the mounting plate and the stepping motor body are bonded together via a rubber elastic body, the elasticity of the rubber absorbs unnecessary distortion and maintains the flatness of the mounting plate.
When this mounting plate is fixed to the chassis of a device, the vibrations and noise of the motor are absorbed by the elasticity of the rubber and are prevented from being transmitted.

ジェクション加工が不要になシエ数も低減している。When the vulcanized rubber is formed, adhesive force is generated between the stepping motor main body or its outer frame 1 and mounting plate 2, which are metal plates, and the vulcanized rubber due to vulcanization adhesion, resulting in the structure of the present invention. In order to strengthen the adhesive force, it is effective to roughen the surface of the metal plate, provide a projection to prevent slippage, or use metal plating in combination. According to the above manufacturing method, since no extra strain is applied to the stepping motor main body, its outer frame 1, or the mounting plate 2, it is possible to maintain the dimensional accuracy and fix the two together, and the mounting plate 2 The accuracy of the plane is also improved compared to the previous model. Additionally, projection processing is no longer required, reducing the number of screens.
