Constrained modal analysis of double circular arc gear
According to the standard tooth profile geometric relationship of GB / T 12759-1991, according to the gear parameters (z = 51, M = 4 mm α = 24°、 β = 20. 263 °, B = 60 mm), using croe software to establish the parametric solid model of double circular...

Regression analysis of double circular arc gear
The relationship between dependent variables and regression analysis is a kind of modeling technology. The experiment involves four independent variables, and the units of independent variables are different, which brings some difficulties to the structural analysis of regression equation. For multiple linear regression, the data should be centralized first...

Research on double circular arc gear
The vibration of the gear system will be caused in the process of gear rotation and meshing. If the natural frequency of the gear overlaps or is close to the meshing frequency, resonance will occur. Resonance can produce large dynamic stress at the tooth root and accelerate the fatigue...

Determination of cutting force of cylindrical gear with variable hyperbolic arc tooth profile
Because there are many and complex influencing factors in the milling process, there is no theoretical formula to directly calculate the cutting force in each direction. The usual method is to conduct a large number of experiments to obtain empirical formulas. In the empirical formula of cutting force, the...

Finite element analysis of cylindrical gear with variable hyperbolic arc tooth profile
In the finite element analysis of the whole machine, the contact between parts has a great impact on the analysis results, so it is necessary to set the contact pair reasonably. The types of joint surfaces of special machine tools for variable hyperbolic arc tooth profile cylindrical gears are...

Structure of cylindrical gear machine tool with variable hyperbolic arc tooth profile
In finite element analysis, the solution efficiency is low and the time cost is greatly increased because the machine tool model is too complex. Therefore, when creating the finite element model, simplify the model according to the following principles: (1) ignore the geometric features on the machine tool that...
