Manufacturing process of compound pendulum rotating shaft with automatic deflection correcting function

Abstract

The invention relates to a compound pendulum, in particular to a manufacturing process of a compound pendulum rotating shaft with an automatic deflection correcting function. The invention adopts the technical scheme as follows: a core rod of a rotating shaft is 6.5cm long; the core rod is divided into two sections due to two different diameters; one section with the diameter of 7mm is 5cm long, and the rest section has the diameter of 4.9mm; two bell bearings with the same structure and the same size are sleeved onto the core rod with the diameter of 4.9mm; the bell bearings have the outside diameters of 7.9mm and have the axial thicknesses of 3mm; the distance between the two bell bearings is 1mm; the thicker end of the core rod is fixed inside a rotating shaft hole of a compound pendulum support through a screw. The bearings can automatically correct a pendulum rod, so that the pendulum rod can swing in a balanced way within 7 seconds.

Description

technical field [0001] The invention relates to a compound pendulum, in particular to a manufacturing process of a compound pendulum shaft with automatic deviation correction function. Background technique [0002] Presently known compound pendulum is made of two parts: the one, fork, the 2nd, support, and wherein the profile of fork is a rectangular metal plate, and dozens of circular through holes are distributed along the longitudinal center line on the plate. In the experiment, the hole of the swing rod is set on a triangular prism arranged horizontally above the bracket, and the top of the hole of the swing rod is combined with the edge above the triangular prism. When the lower end of the swing rod is pulled away from the equilibrium position and released, the swing rod begins to swing. According to the experimental principle, this swing must be a smooth swing in a vertical plane, so that the error of the acceleration of gravity measured by this will tend to be the sm...

However, the long-term teaching practice shows that the above scheme is feasible for teachers with operating experience, but many students have deflected due to improper control of the traction direction when pulling the pendulum away from the equilibrium position, so the pendulum is released. There is twisting phenomenon
