Embodiment Construction

[0010] From figure 1 It can be seen from the figure that a lunar drive device for an earth-moon transmission includes a lunar body 14, a lunar body orbital circle 1, a moving circle 4, and the like. The orbital ring 1 is an annular fixed carrier fixed on the base, which has the characteristics of resistance to bearing force, no deformation, and strong stability. Two ring-shaped fixed rails 2 are installed on the inner bottom surface of the track ring, which can smoothly support the sliding operation of the moving ring supporting wheel 3 . The orbital ring 1 inner side is provided with the lunar body rotation gear ring 5, and an annular moving ring 4 is installed in the orbital ring. The moving coil 4 is located on the ring-shaped fixed track 2 inside the orbit ring 1, supported by several moving coil support wheels 3, and is an annular carrier that can rotate around the center of the ring-shaped fixed track 2 to carry the revolution and autobiography of the moon. The moving ...

Abstract

The invention relates to a moon drive device of an earth-moon transmission instrument, comprising a moon body and an orbit ring, wherein the inner bottom surface of the orbit ring is provided with an annular fixed orbit, the inner side surface of the orbit ring is provided with a moon body autorotation gear ring, the orbit ring is movably mounted with an annular movable ring inside, the movable ring is mounted on the annular fixed orbit by a movable ring riding wheel, the moon body is mounted on the movable ring by a connection base and a rotation base; the outside of the movable ring is mounted with a moon body revolution gear ring which is meshed with a transmission gear driven by a power transmission shaft arranged at the outside of the orbit ring; the moon body is internally provided with an autorotation transmission shaft and a gear variable transmission mechanism, the movable ring is mounted with a primary transmission gear which is meshed with the moon body autorotation gear ring on the orbit ring, and the primary transmission gear drives the moon body to auto-rotate on the movable ring. The invention has reasonable structure, and the autorotation and revolution of the moon body are simple and independent. The invention is suitable for being mounted on the earth-moon transmission instrument as the moon drive device, and can be used as a teaching and scientific research model and as a large sight-seeing apparatus in public entertainment locations, and integrates the function with the sight effect.

Description

technical field [0001] The invention relates to an earth-moon movement demonstration transmission device for simulating the movement of celestial bodies, in particular to a lunar drive device for the earth-moon transmission device. Background technique [0002] We know that at present people have mastered the laws of operation of the sun, the earth and the moon and related knowledge. For the convenience of teaching, scientific research and demonstration, various models and demonstration instruments have been made. Most of them are manual demonstrations, which are cumbersome to operate and not very enjoyable to watch. Chinese patent ZL2005200511361 discloses a demonstration instrument for the movement of the earth and the moon. Its base is a transmission gearbox, and its output shaft is a set of differentially rotating central shaft and hollow shaft. A rotating arm is fixed on the hollow shaft, and one end of the rotating arm is fixed with a The core shaft and the empty sle...
