Abstract

The invention discloses a method for using a multi-motion pair gap measurement experimental device. The experimental device includes an experimental platform, a drive assembly, a gear assembly, a crank slider assembly, and a cam push rod assembly; the gear assembly is passed through a ball screw knob Adjust the displacement of the gear base to adjust the tooth side clearance of the driving gear and the driven gear. The crank slider assembly realizes the adjustment of the upper, lower, left, and right clearances by setting two kinds of clearance adjustment slide rails. The cam push rod assembly moves through the Z axis The platform adjusts the offset displacement, which can realize the experiment of 16 kinds of cam mechanisms with two types of cams, four kinds of push rods and two modes; its use methods include gear linkage mechanism, crank slider mechanism, gear-cam mechanism about tooth backlash, The measurement experiment of the rotating pair gap, the moving pair gap and the cam pair gap; the invention has high integration, various kinds of gaps and is convenient and adjustable.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing experimental devices, in particular to a method for using an experimental device with conveniently adjustable gaps and various types of motion pairs. Background technique [0002] As we all know, with the continuous development of precision mechanical engineering, the requirements for mechanical products in engineering are getting higher and higher. High precision, high efficiency, high performance and high reliability are important standards for measuring excellent products. The ubiquitous kinematic pair clearance in the mechanical system is an important factor affecting the system performance. The influence of the clearance on the dynamic characteristics of the mechanism is a complicated process. The current research on the dynamic characteristics of the multi-body system with the kinematic pair clearance has become a modern mechanical hot issues in engineering. But as far as t...
