Double-wheel-disc gyro precession demonstration device

Abstract

A double-wheel-disc gyro precession demonstration device comprises an input part, a transmission partand a demonstration part, wherein the input partcomprises a hand wheel, and a hand wheel shaft of the hand wheel transmits power to a small synchronous belt wheel; the transmission part comprises a main shaft, and a large synchronous belt wheel which transmits power with the small synchronous beltwheel through a synchronous belt is arranged on the main shaft; and the demonstration part comprises an outer ring, the outer side of the bottom of the outer ring is connected with the uppermost end of the main shaft, the outer ring is connected with the inner ring through an inner-outer ring connecting shaft, the inner ring can rotate along the inner-outer ring connecting shaft, one ends of the two symmetrical turntable sleeves are fixed on the inner wall of the inner ring, the other ends are respectively connected with a turntable, the two turntables are connected through the turntable connecting shaft, a motor is arranged in each turntable sleeve, and a coupler of each motor drives one turntable to rotate. The precession phenomenon and related properties of the gyro can be vividly and visually demonstrated, and the principle of precession phenomenon generation is fully demonstrated through multiple gyro rotation modes.

Description

technical field [0001] The invention belongs to the technical field of teaching and demonstration experimental instruments, and particularly relates to a double-disc gyro precession demonstration device, which is suitable for displaying the principle of gyro precession. Background technique [0002] The gyro precession phenomenon is an important physical phenomenon, and the gyroscope based on the gyro precession phenomenon has important applications in positioning and navigation systems. In order to enable learners to understand the stability characteristics of the precession phenomenon and the principle of the precession phenomenon, many gyro precession demonstration devices used in popular science and teaching have been invented, among which the authorized and published patents include "A Gyro Precession Dynamic Demonstration Apparatus" (Application No.: 201420391706.0 Announcement No.: CN203931278U), "A Demonstration Device for Gyro Characteristics" (Application No.: 2014...

AI Technical Summary

Problems solved by technology

Most of the precession demonstration devices that have been invented so far imitate the classic two-degree-of-freedom gyroscope structure, with only one self-rotating gyroscope. Although it can clearly demonstrate the precession phenomenon, it is difficult to clearly explain the cause of the precession phenomenon.

In addition, these precession demonstration devices are often complex in structure but single in function, unable to achieve precise control of gyroscope rotation speed, and lack an interface for interactive demonstration with the audience
