Verification instrument for gear center distance severability

Abstract

The invention discloses a verification instrument for gear center distance severability, and belongs to the field of demonstration teaching tools. A driving gear rotation device drives a driving gear to rotate, and the driving gear transmits torque to a driven gear through tooth profile meshing; the change of angular displacement between the driving gear and the driven gear is detected through a detection unit in real time and is displayed through a digital display device; the consistency of the instantaneous transmission ratio of gear transmission is determined by observing the synchronization of the change of the rotating angle between the driving gear and the driven gear; the center distance between the driving gear and the driven gear is changed through a center distance adjusting device; under different center distance conditions, experiments are performed many times so that the gear center distance severability can be verified. The novel demonstration teaching tool is provided for classroom teaching of the gear center distance severability content of an involute profile; besides, as the verification instrument is organically combined with the theoretical teaching modes of text representation and formula derivation, boring knowledge points can be displayed vividly, and the effect of classroom teaching is effectively improved.

Description

technical field [0001] The invention relates to a demonstration teaching aid, in particular to a gear center distance separability verifier. Background technique [0002] The course "Mechanical Principles" is a backbone course for mechanical and near-mechanical majors, and gear transmission is an important content of mechanical transmission. [0003] Gear transmission is realized by pushing the tooth profile of the driven wheel by the tooth profile of the driving wheel. The most basic requirement of gear transmission is accurate and stable transmission, that is, the instantaneous transmission ratio must remain unchanged, otherwise, when the driving wheel rotates at a constant angular speed, the driven wheel rotates at a variable angular speed, and the inertial force generated not only affects the life of the gear , And it will cause vibration and noise of the machine, affecting the working accuracy. [0004] Such as figure 1 The schematic diagram of the basic law of tooth...
