Abstract

The invention discloses a planetary gear train gear tooth state evaluation method and a device thereof, equipment and a medium. Harmonic signals are removed through Vold-Kalman filtering, Protrugram analysis is performed on residual signals, in combination with a modal analysis result, a frequency band where impact vibration is located is recognized, internal and external meshing impact is distinguished, a zero-phase-shift band-pass filter is constructed to extract internal and external meshing impact vibration signals, RMS time domain synchronous average analysis is carried out, and the state of each gear tooth of the planetary gear train is visually evaluated. Compared with a traditional fault diagnosis method based on fault characteristic frequency identification, the fault diagnosis method fully utilizes frequency information, phase information and amplitude information contained in the impact vibration signals, can realize positioning of fault gears, distinguishing of fault types and accurate evaluation of fault damage severity, is visual in result and high in visualization, and facilitates reference of field maintenance personnel.

Description

technical field [0001] The invention belongs to the technical field of fault diagnosis of planetary gear boxes, and in particular relates to a method, device, equipment and medium for evaluating the tooth state of a planetary gear train based on RMS time-domain synchronous averaging technology. Background technique [0002] The planetary gear train has the advantages of light weight, small size, high load capacity, compact structure, and high transmission efficiency, and is widely used in large-scale mechanical equipment such as aerospace, metallurgical mining, and wind power generators. Due to the harsh working environment, the planetary gear train is prone to local failures. When a gear tooth has a partial fault, due to the reduction of the local bearing capacity, the fault will further develop and induce the failure of other gear teeth; when the fault develops seriously, it will cause the equipment to stop and cause economic losses. [0003] Analyzing vibration signal ch...
