analytical gear

The gear strength calculation is based on the calculation formula proposed by and. Various coefficients are used to correct the

In the establishment of mechanical model, the gear tooth is simplified as a cantilever beam, and the contact state under

In fact, the so-called fatigue tooth breaking problem is that the mechanical gear breaks, and the whole spur gear will

By establishing a simplified six degree of freedom dynamic mathematical model of gear system and a rigid body dynamic analysis

By referring to the physical causes of fatigue pitting on tooth surface and the characteristics of pitting pits, different mesh

The test method usually adopts quasi-static analysis conditions, which can accurately calculate the TVMs of gear meshing pair. In practical

Finite element method (fem) is to the gear body and tooth discrete into tiny unit elastic body, and through the

Through the gear contact fatigue test-bed, the evolution process of gear fatigue pitting phenomenon and the vibration response characteristics of

Chen et al. deduced and studied the influence of the meshing stiffness of the internal meshing gear pair and the

As a new mathematical theory and method, wavelet transform has been widely used in many fields. In vibration signal analysis,

Gear cepstrum analysis The frequency spectrum of gear vibration is usually represented by meshing frequency and harmonic sideband, which is
