DETAILED DESCRIPTION

[0018] In order to facilitate the understanding of the present application, the present application will be described in more detail below in conjunction with the drawings and specific embodiments. The preferred embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms, and is not limited to the embodiments described in the specification. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0019] It should be noted that, unless otherwise defined, all technical and scientific terms used in the specification have the same meaning as understood by those skilled in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application.

[0020] An embodiment of a planetary rotation standard rotational speed generating device in the present application is shown in the drawings as follows: Figures 1-3 The device base 1 is provided with a controller 12 and a revolution motor support 2. The revolution motor support 2 is a "J" shaped structure with a support top plate. The revolution motor support 2 is provided with a revolution motor 13. Specifically, the shell of the revolution motor 13 is fixed to the bottom of the support top plate by bolts. The motor shaft of the revolution motor 13 is vertically arranged. The upper end of the motor shaft of the revolution motor 4 passes through the upper side of the support top plate 11. The second bearing 15 is arranged between the motor shaft of the revolution motor 4 and the support top plate 11.

[0021] The upper end of the motor shaft of the revolution motor 4 is fixed with a revolution turntable 6. The revolution turntable 6 is fixed with a rotation motor support 10. The structure of the rotation motor support 10 is the same as that of the revolution motor support 2. However, the rotation motor support is a proportionally reduced structure of the revolution motor support. The size ratio of the rotation motor support to the revolution motor support is 1:2.

[0022] The rotation motor support is provided with a rotation motor 7 which is arranged eccentrically with the axis of the revolution turntable. The motor shaft of the rotation motor is fixed with a rotation turntable 8. The rotation motor 7 is arranged on the inner side of the "J" shaped structure of the rotation motor support 10.

[0023] The controller is electrically connected with the revolution motor and the rotation motor through the first wire and the second wire respectively. A rotating disc sleeve 5 is coaxially fixed on the revolution rotating disc 6. A conductive slip ring is connected in series on the second wire. The conductive slip ring comprises a conductive ring 19 fixed on the rotating disc sleeve and a conductive contact 18 fixed on the revolution motor support and in sliding contact with the conductive ring.

[0024] In the embodiment, the rotating disc sleeve 5 is made of insulating material. The revolution motor support is provided with an annular mounting groove 16 coaxially arranged with the revolution rotating disc. The lower end of the rotating disc sleeve 5 is an installation end 17 extending into the annular mounting groove. A first bearing 14 is arranged between the installation end 17 and the inner side groove wall of the annular mounting groove. The cooperation of the first bearing 14 and a second bearing 15 ensures that the rotating disc sleeve and the revolution rotating disc rotate coaxially with the motor shaft of the revolution motor.

[0025] The first bearing 14 is arranged between the inner side of the installation end and the inner side groove wall of the annular mounting groove. Compared with the first bearing arranged on the outer side of the installation end, the first bearing 14 has a smaller diameter and is lower in cost.

[0026] The conductive ring 19 is fixed on the outer periphery of the rotating disc sleeve 5. The conductive contact 18 is fixed on the outer side groove wall of the annular mounting groove 16. The second wire comprises a second wire first part 20 connected between the conductive ring and the rotation motor and a second wire second part connected between the conductive contact and the controller. The second wire first part is fixed between the rotation motor and the conductive ring. The conductive contact and the conductive ring are located in the annular mounting groove and do not leak out, avoiding the influence of electric leakage on the operator.

[0027] The controller 12 controls the revolution motor to output a fixed rotating speed through the first wire and controls the rotation motor to output a fixed rotating speed through the second wire, thereby simulating a planetary rotating mechanism. The arrangement of the conductive slip ring can avoid the influence of the revolution rotating disc on the second wire, ensuring the normal operation of the equipment.

[0028] In the above description of the present specification, unless otherwise explicitly specified and limited, the terms "fixed", "mounted", "connected" or "linked" and the like should be understood in a broad sense. For example, as to the term "connected", it can be fixed connection, detachable connection or integral; it can be mechanical connection, electrical connection; it can be direct connection or indirect connection through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements. Therefore, unless otherwise explicitly limited in the present specification, the above terms can be understood in the specific meaning in the present application by the person skilled in the art according to the specific circumstances.

[0029] According to the above description of the present specification, those skilled in the art can also understand that the terms used such as "upper", "lower", "front", "back", "left", "right", "length", "width", "thickness", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", "center", "longitudinal", "transverse", "clockwise" or "counterclockwise" and other terms indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings of the present specification, which are only for the purpose of facilitating the description of the present application and simplifying the description, and are not explicitly or implicitly indicating that the devices or elements involved must have the specific orientation, be constructed and operated in a specific orientation, therefore the above orientation or positional relationship terms cannot be understood or interpreted as a limitation on the technical solutions of the present application.

[0030] In addition, the terms "first" or "second" and the like used in the present specification are terms used to refer to numbers or ordinal numbers only for the purpose of description, and cannot be understood as explicitly or implicitly indicating relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first" or "second" can explicitly or implicitly include at least one of the features. In the description of the present specification, the meaning of "plurality" is at least two, such as two, three or more, etc., unless otherwise explicitly and specifically limited.

[0031] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
