Abstract
The invention discloses an experimental device for measuring gaps between multi-movement pairs, which comprises an experimental platform, a drive assembly, a gear assembly, a crank slider assembly, and a cam push rod assembly. It is characterized in that the gear assembly includes a driving gear, a driven gear, a driving gear base, a driven gear base, a gear guide rail, and a ball screw, and the displacement of the gear base is adjusted through the ball screw knob to adjust the driving gear and the driven gear The tooth side clearance of the crank slider assembly has a crank, a connecting rod, a slider, a linear guide rail, and a clearance adjustment slide rail. The adjustment of the upper, lower, left, and right clearances is realized by setting two kinds of clearance adjustment slide rails. The cam push rod assembly Including cam, Z-axis moving platform, push rod, spring, push rod follower, and right-angle support frame, the offset displacement can be adjusted through the Z-axis moving platform, and two types of cams, four kinds of push rods and two modes can be realized, a total of 16 kinds of cams Institutional experiments. The device has reasonable structure, high integration, various kinds of gaps and is conveniently adjustable.
Description
technical field [0001] The invention relates to the technical field of mechanical manufacturing experimental devices, in particular to 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 the current exper...
