Keep the contact boundary condition with smooth gear consistent with the loading setting treatment method, restrict the degrees of freedom of all nodes in the inner hole of large gear, and select the constant value of all DOF as 0; Constrain the degrees of freedom of all nodes in...
The three-dimensional solid model of the gear is established by CATIA. After being imported into ANSYS, a series of spherical units are on the gear contact surface by using the general preprocessor in ANSYS, and these spherical units are subtracted on the gear surface by using the subtraction function...
In order to study the influence of different modification coefficients on the strength of cylindrical gears, a group of cylindrical gear parameters are selected, as shown in the table. The three-dimensional models of cylindrical gear pairs are established according to different displacement coefficients, and then analyzed according to the...
The distribution of metal streamline in each step of the blank making process of cylindrical gear ring is shown in the figure. Figure (a) shows the distribution of metal flow lines when the upsetting process is completed. After upsetting, most of the metal flow lines are exposed. These flow...
1. Import model Through the method discussed above, we can establish the three-dimensional model of the modified cylindrical gear in Pro / E, then import the geometric model into ANSYS Workbench, give the material attribute of the model as “structural steel” in the mechanical module, and modify the material...
The research on Isothermal Elastohydrodynamic Lubrication of cylindrical gears does not consider the influence of time and temperature changes on oil film pressure and oil film thickness. The normal load on the gear teeth remains unchanged, and the cylindrical gears rotate at a uniform speed. The test gear is...
1. Equivalent stress analysis of three-dimensional contact of smooth cylindrical gear The results of three-dimensional contact equivalent stress of cylindrical gear by using ANSYS general post processor show that figure 1 is the cloud diagram of equivalent stress distribution of smooth cylindrical gear contact and the local enlarged diagram...
According to the static contact analysis principle of cylindrical gear, the passive cylindrical gear needs to be completely fixed, and the driving cylindrical gear applies a certain load torque. That is, in the node coordinate system, select all nodes on the inner hole surface of the big gear and...
Figure 1 shows the three-dimensional contact solid model of cylindrical gear after importing ANSYS. The general preprocessor in ANSYS is used to set the material properties and relevant parameters of cylindrical gear; The element type of the two cylindrical gears adopts 3D solid185. The three-dimensional contact finite element model...
In order to verify the fatigue pitting corrosion model of cylindrical gear, the FZG cylindrical gear wear tester in the Key Laboratory of mechanical transmission of Chongqing University is used for testing, as shown in the figure below. The equipment is based on din51354, GB / T 14230-93, Nb...
