Abstract

A multifunctional shafting test device based on planetary transmission, comprising: a test assembly, a vibration isolator, a stand, and a base. The test components include: drive motor, input coupling, dynamic balance test disk, sliding coupling, torsional vibration test tooth disc, test load, first rotating shaft, second rotating shaft; the motor shaft of the driving motor is connected to the input end. The coupling at the input end is connected to the test part through the rotating shaft; the rotating shaft between the coupling at the input end and the test load is equipped with a dynamic balance test disc, a torsional vibration test tooth disc, a dynamic balance test disc and a torsion test load. A sliding coupling is installed between the vibration test tooth discs through the first rotating shaft and the second rotating shaft, and the sliding coupling is installed on the table body through the bracket; the test components are installed on the bench, and a vibration isolator. The device of the invention is easy to reorganize and can realize the multifunctional test of the vibration characteristics of the shafting device based on the planetary transmission.

Description

technical field [0001] The invention belongs to the field of shafting vibration, in particular to a multifunctional shafting test device based on planetary transmission. Background technique [0002] Planetary gears are widely used in engineering fields such as lifting transportation, construction machinery, and aerospace because of their outstanding advantages such as high load-carrying capacity, large transmission power, and compact structure. However, when planetary gears run at high speeds and under heavy loads, they will produce different levels of vibration and noise problems, which will not only reduce the transmission accuracy and service life of the gears, but also affect the working accuracy and life of the entire shafting device. It will cause noise pollution and affect people's health. [0003] In recent years, with the rapid development of the ship industry, higher and higher requirements have been put forward for the vibration and noise of the planetary gear s...
