TERRESTRIAL GLOBE MODEL WITH FREE PRECESSION MOVEMENT

摘要

The invention relates to a terrestrial globe model with free precession movement, which facilitates understanding of the precession movement of the earth, comprising: a terrestrial globe (4) comprising two poles, which globe can rotate freely in relation to a polar shaft (5) that extends through the poles; and a vertical shaft (3) joined to the polar shaft (5). According to the invention, the vertical shaft (3) can rotate freely in relation to a base (1) and the polar shaft (5) is inclined in relation to the vertical shaft (3).
