Parametric design of involute gear transmission system

According to the performance requirements of the reducer, the technical parameters are determined on the basis of the above structural scheme, and eight links are discussed, including transmission ratio distribution, motion and motion parameter design, mechanical model establishment, strength design of involute gear pair, shafting structure and strength check,...

Development of gear transmission dynamics

1) Analytical theory The theoretical basis of gear transmission dynamics research is mechanical linear dynamics theory and nonlinear dynamics theory, but the two theories develop with the development of gear transmission dynamics research. Before the 1950s, gear transmission was usually studied as a single degree of freedom system, and...

Torsional vibration of bevel gear transmission

There are two kinds of torsional vibration of bevel gear transmission system: low-frequency torsional vibration and high-frequency torsional vibration. Low frequency torsional vibration is determined by the vibration of the system. For the central bevel gear of aeroengine, because the natural frequency of low-frequency torsional vibration is usually outside...
