Abstract

PURPOSE:To smooth the rotation of a rotor so as to improve responsibility, by connecting a generator of which field currents can be adjusting by a field current adjusting means to the rotor of a rotating machine which is driven by a driving means. CONSTITUTION:A servo motor 3 rotates a rotary table 1 via a pinion 2' and a ring gear 2. A generator 7 which is fixed to a support bed 4 by a bracket 8 is directly connected to the rotation axis 1a of the rotary table 1, so that specific induced electromotive force is generated corresponding to the strength of given field currents. Thus, the rotation torque of the generator 7 is loaded to the rotation of the rotary table 1 as viscous resistance, and minute rotation unevenness of the rotary table 1 is absorbed. Furthermore, the strength of the viscous resistance can be adjusted, by the adjustment of a field current adjusting means 7a which adjusts the strength of field currents, corresponding to the inertial mass of the rotary table 1, the play amount of a rotor driving means and the like.

DETAILED DESCRIPTION OF THE INVENTION <Industrial Field> The present invention relates to a rotating device with a viscous resistance device for stabilizing the rotation of the rotating device.

<Conventional technology> Conventionally, NC? t,1JIj1! In a rotating device having a servo mechanism such as J or copy control, a gear interlocking mechanism is used as a mechanism for transmitting power from a driving means to a rotating body.

<Problems to be solved by the invention> In particular, when gears are used in the power transmission mechanism of a conventional rotating device, various problems such as minute vibrations of the gears, irregular slippage on tooth surfaces, inertia, etc. Due to a combination of factors, the rotating body of the rotating device could not operate stably and smoothly.

The present invention has been made in view of the problems of the prior art, and an object of the present invention is to provide a rotating device in which a rotating body can operate smoothly.

Means for Solving the Problems> A rotating device with a viscous resistance device according to the present invention has a rotating body rotatably attached to a support base and driven via a rotating body driving means, and a rotating body fixed to the support base.

<Operation> A generator is connected to the rotating body driven by the rotating body driving means via the interlocking means, and therefore, the rotational torque of the generator loads the rotating body as viscous resistance. Further, the magnitude of the viscous resistance is adjusted to a desired value by an adjusting means depending on the rotational speed of the rotating body and the like.

Embodiment As shown in FIG. 1, which shows the cross-sectional shape of an embodiment of the rotating device with a viscous resistance device according to the present invention, the rotating shaft 1a of the rotating table 1 constituting the rotating body is aligned with respect to the support base 4. It is rotatably mounted by a thrust bearing 5 and a radial bearing 6 so as to be perpendicular to each other. Further, a ring gear 2 is attached to the outer peripheral surface of the rotary table 1, and this ring gear 2
is meshed with a pinion 2' of a servo motor 3, which is a rotating body driving means fixed to a support base 4. Therefore,
The rotary table 1 is rotated by the drive of the servo motor 3!
@ It is designed to be moved. A rotating shaft 9 of a generator 7 fixed to a support base 4 via a bracket 8 is mechanically connected to the lower end of the rotating shaft 1a of the rotating table 1 as a coaxial unit.

A servo motor 3 rotates a rotary table 1 via a pinion 2' and a ring gear 2, and a bracket 8 is attached to a support base 4.
Since the generator 7, which is fixed by loads as viscous resistance against the rotation of the rotary table 1, and subtle rotational irregularities of the rotary table 1 are absorbed. Further, the magnitude of the viscous resistance can be easily adjusted according to the inertial mass of the rotary table 1, the play amount of the rotating body driving means, etc. by adjusting the field current adjusting means 7a that adjusts the magnitude of the field f4 flow. I can do it.

In this embodiment, the servo motor 3 is placed on the side of the rotary table 1, and the generator 7 is placed on the rotary shaft 1 of the rotary table 1.
a, but conversely the servo motor 3 is connected to the rotary table 1.
Of course, it is also possible to configure the power generation PJ 7 to be directly connected to the rotating shaft 1a of the rotary table 1 and to be driven by a ring gear 2 provided on the outer peripheral surface of the rotary table 1 and a pinion 2' that meshes with the ring gear 2.

<Effects of the Invention> According to the rotating device with a viscous resistance device of the present invention, the rotating body of the rotating device driven by the driving device is connected to a generator whose field current can be adjusted by the field current adjusting device. , it was possible to add the rotational torque of the generator to the rotation of the rotating body as viscous resistance, which not only made the rotation of the rotating body of the rotating device significantly smoother, but also improved the responsiveness of the rotating body. You can do it. Further, it is possible to easily add an optimum viscous resistance according to the arbitrary rotational speed of the rotating body of the rotating device, thereby significantly improving the performance and usefulness of the rotating device.
