Spur gear meshing impact excitation

Ideally, the meshing form of spur gear pair is shown in Figure 1. It can be seen that one end of the gear teeth is “perfectly engaged”, and the other end has a certain gap due to the existence of backlash. However, due to errors, time-varying meshing stiffness and...

Analysis of spur gear error excitation

The large number of studies have proved that dynamic excitation is the main cause of spur gear vibration, which is mainly divided into internal excitation and external excitation. Since external excitation refers to the excitation of spur gears by other components in the system and the effective torque and...

System equation of spur gear pair

The dynamic model of 8-DOF spur gear pair is established by Lagrange equation. The system equation is: Where: FM is the dynamic meshing force of spur gear; RB1 and Rb2 are the radii of the driving wheel and the driven wheel respectively; IF1 and IF2 are the moment of...

Flash temperature model of spur gear pair

For tooth surface contact temperature: Δ T. Mainly determined by the temperature of spur gear body Δ M and tooth surface flash temperature Δ F is composed of two parts, namely: Spur gear body temperature Δ M is generally assumed to be constant, and the tooth surface temperatures of...
