Analysis on forging load of equal height spiral bevel gear blank
The service life of die and the selection of screw press are closely related to the forming load. Therefore, it is necessary to focus on the analysis of the change of load in the forging process. Firstly, taking the blank of No. 2 equal height spiral bevel gear as...

Variation law of stiffness during machining of straight bevel gear blank
In the process of cutting teeth, the material of straight bevel gear blank continues to be cut off, and the overall stiffness of straight bevel gear blank will gradually decrease in theory. However, considering that the stiffness reduction degree caused by different cutting positions of the split gear blank...

Deformation analysis of straight bevel gear blank during machining
When the straight bevel gear split wheel blank is cut, the material of the cogging part is removed, and the stress contained in the cogging material disappears, which is the substantive reason for the deformation of the straight bevel gear split wheel blank in the machining. In this paper,...

Stiffness variation characteristics and theoretical modeling in straight bevel gear blank machining
Stiffness is a characteristic value to measure the resistance of straight bevel gear blank to deformation during tooth cutting. The greater the stiffness of straight bevel gear blank, the less likely it is to deform. In material mechanics, the stiffness is usually expressed by the product of the elastic...

Machining deformation of gear blank integral components
Based on theoretical calculation and finite element simulation, Sun Jie and Ke Yinglin of Zhejiang University studied the influence of the initial internal stress of the gear blank of large integral structure on its NC machining deformation, and solved the deformation of the rectangular section beam with unidirectional stress...

Simulation of gear cutting process of straight bevel gear blank
The process of gear cutting of straight bevel gear blank is actually the process that the material in the tooth groove of straight bevel gear blank is gradually removed. This is a dynamic process. In the finite element analysis of ABAQUS, it is necessary to simulate this dynamic process...

Stress evolution law of spur bevel gear blank in gear cutting
The deformation of extra large split spur bevel gear blank in the process of gear cutting is closely related to the instantaneous stress distribution of spur bevel gear blank. Therefore, the stress evolution analysis should be carried out through finite element simulation, and the stress state of the surface...

Numerical simulation of forging process of driven spiral bevel gear blank
Combined with the practice of ZHY gear, the forging process of driven spiral bevel gear blank is numerically simulated. In the production of driven spiral bevel gear, the die design and process formulation of ZHY gear depend on the methods of experiment and experience, while the forging process of...
