With the help of ANSYS / LS-DYNA, the finite element model of gear meshing pair is solved, and the gear stress nephogram is obtained, as shown in Figure 1. Through the stress nephogram of the big and small gears, it can be seen that the stress distribution on the...
The time-varying meshing stiffness excitation and the transmission error excitation are two very important excitations in the actual operation of gears, which will directly affect the vibration response of the gear pair. The existence of tooth thickness deviation will directly affect the meshing stiffness and transmission error of the...
Because the backlash of gear pair is usually realized by controlling the tooth thickness deviation, there must be a certain tooth thickness deviation in the actual operation of the gear, and the manufacturing and installation errors and temperature changes will further affect the tooth thickness deviation. Firstly, the meshing...
Gear transmission is one of the most commonly used transmission in all kinds of machinery, which has the advantages of reliable operation, accurate transmission ratio and less power loss. However, due to the existence of manufacturing and installation errors, there will be various deviations of gears. The existence of...
The quasi-static calculation method is adopted in the finite element simulation calculation, that is, the stiffness under the load at any meshing point is assumed to be independent, which is consistent with the time-varying meshing stiffness calculated by the above analytical method. Fig. 1 draws the time-varying meshing stiffness...
In order to further calculate the meshing interval expression of gear in a single period from meshing in to meshing out and the relationship between each single double meshing interval and rotation angle. Figure 1 shows the detailed meshing geometric diagram of the spur gear pair at the initial...
According to the spatial meshing principle of involute spur gear, when a pair of standard involute tooth profiles are meshed, the meshing points moving along the tooth profile are scattered on the internal common tangent (ideal meshing line) between the two base circles of the gear pair, as shown...
