Abstract

The invention discloses an engine balance system test platform device. In the invention, a rotary assembly is arranged in the main body of the device, and a motor part is arranged inside the rotary assembly. The operation of the motor part drives the output shaft part to run at high speed, and the output shaft part is connected to the eccentric wheel part. When rotating, the eccentric wheel part drives the slider part to move up and down through the conductive part. When the conductive part rotates, a moment of inertia will be generated, and the moment of inertia will be balanced by the slider part to simulate the working state of the engine. On the other hand, the eccentric wheel part drives the rear gear part to rotate, and the gear part will generate vibration displacement and noise when it rotates at high speed. The noise and vibration displacement are collected and recorded by the sensor part. After summarization, through analysis, the comparison of different vibration noise amplitudes It can be seen that the structure of different gears is good or bad.

Description

technical field [0001] The invention relates to the technical field of equipment detection, in particular to an engine balance system test platform device. Background technique [0002] In the industrial society of the 21st century, industries such as general machinery and automobiles are prospering day by day, and the gears widely used in these industries have also entered the era of mass production. In the gear manufacturing industry, since most of the gears and shafts in the automotive industry adopt interference or transitional assembly, assembly line assembly, and the gears are closely arranged inside and outside, if abnormal noise is found during the test run, find out the burrs in the gear set It is very difficult to disassemble and replace gears, which will take a lot of time and energy, and seriously affect production efficiency; at the same time, in the application stage of gears, the gear chamber is an important part of the car engine. The function of the existin...
