Abstract

The invention relates to a friction vibration test device and a test method thereof. The test device comprises a base. A motor, a to-be-tested gear reducer and a hydraulic dynamometer are arranged on the central axis of the upper end face of the base in sequence. The output shaft of the motor is connected with the input shaft of the to-be-tested gear reducer through a coupling. The output shaft of the to-be-tested gear reducer is connected with the spindle of the hydraulic dynamometer through a coupling. A piezoelectric acceleration sensor is fixedly arranged on the to-be-tested gear reducer. The test method combines friction test, wear test and vibration test. After multiple sets of information are fused, a new integrated state index is obtained, which is used as the basis of next step of state identification.

Description

technical field [0001] The invention belongs to the technical field of equipment detection in a mechanical transmission system, and in particular relates to a friction vibration testing device in a mechanical transmission and a testing method thereof. Background technique [0002] As a key transmission component in the national economy and national defense construction, planetary gears are widely used in mechanical transmission systems in wind power, aviation, shipbuilding, metallurgy, petrochemical, mining, lifting and transportation industries. The gearbox has many advantages such as light weight, small size, large transmission ratio, strong bearing capacity, and high transmission efficiency. However, in the harsh working environment of low speed and heavy load, the key components such as the sun gear, planetary gear, and planet carrier are often severely worn or damaged. Failures such as fatigue cracks. Based on the above situation, it is necessary to conduct friction, v...
