Manufacturing process of compound pendulum shaft with automatic deviation correction function

Abstract

The invention relates to a compound pendulum, in particular to a manufacturing process of a compound pendulum shaft with automatic deviation correction function. The technical scheme of the present invention is: the mandrel of rotating shaft is long 6.5cm, and mandrel is divided into two sections because of two kinds of different diameters, and wherein diameter is a section long 5cm of 7mm, and the diameter of remaining part is 4.9mm. The 4.9mm mandrel is set with two bell bearings with the same structure and size in the form of interference fit. The outer diameter of the clock bearing is 7.9mm and the axial thickness is 3mm. The distance between the two bell bearings is The relatively thick end of the mandrel is fixed in the shaft hole of the compound pendulum bracket by screws. The bearing of the invention can automatically correct the deviation of the swing rod, so that the swing rod can swing smoothly 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
