歯車を介して動力の伝達を行なう場合、歯と尚の間に油
膜の厚み、熱膨張、歯のたわみなどが生ずることから、
歯と歯がきしみあって運転ができなくなることがある。When power is transmitted through gears, the thickness of the oil film, thermal expansion, and deflection of the teeth occur between the teeth.
Teeth may clench together, making it impossible to drive.
このようなことから、なめらかな運転をさせるために、
歯面間にあそび、いわゆるバソクラソシを設けている。For this reason, to ensure smooth driving,
There is a play between the tooth surfaces, a so-called bathocraso.

にしたことにある。SUMMARY OF THE INVENTION The present invention aims to solve the above-mentioned drawbacks and provide a power extraction device for a stepping motor that utilizes the holding force and synchronous operation characteristics of the stepping motor to prevent a decrease in mechanical precision caused by vano crush. Its characteristics include a main gear that outputs output, and a plurality of gears that are arranged in corresponding positions on this main gear in mesh with the main gear, and that are each attached to the rotating shaft of each separate stepping motor. A stepping motor is excited so as to reverse a portion of the driving gear, and press some of the driving gears against one side of the teeth of the main gear, and press the other driving gears against one side of the teeth of the main gear. The gears are meshed with each other so as to be in pressure contact with the other surface, and the stepping motors are operated synchronously in the same direction, thereby extracting power from the main gear.

It meshes with the main gear l so as to come into pressure contact with the surface 1b on the back side in the rotational direction of the teeth 101. The stepping motors 5 and 6 are operated synchronously, and prior to operation, the stepping motor 5 is excited and held so as to reverse the drive gear 3, and the stepping motor 6 is rotated forward or reverse to maintain both holding forces. The stepping motor 6 is stopped in a balanced state.

転駆動され、駆動歯車５．６をステップ駆動させる。Prior to operation of the stepping motor 5.6, one side of the stepping motor 5.6 is rotated in the opposite direction in order to eliminate bank crush. For example, stepper motor 5
is excited and held, the stepping motor 6 is rotated forward or reversely, and the stepping motor 6 is stopped when both holding forces are balanced. As a result, ζ, for example, the teeth 301 of the drive gear 3 come into pressure contact with the surface 1a of the teeth 101 of the main gear 1 on the front side in the rotational direction and mesh with the main gear l, and the teeth 401 of the drive gear 4 mesh with the main gear l. The teeth 101 are meshed with the main gear 1 by applying a pressure tm to the surface 1b on the back side in the rotational direction. This eliminates the discrepancy caused by the meshing of the main gear 1 and the drive gear 3.4. Next, when the stepping motor 5.6 is operated synchronously, the stepping motor 5.6 is driven to rotate by a predetermined angle every l pulse, thereby driving the drive gear 5.6 in steps.

In the above embodiment, the main gear 1 is driven in steps using two stepping motors 4.5, but it may be driven using two or more stepping motors 5.6. In addition, stepping motor 5.
Similar effects can be obtained by combining an encoder with a DC motor other than 6.
