Double circular arc gear is a new improved form of traditional gear, which is widely used in the reducer of pumping unit and hoist. There are about 55000 pumping units in operation in Daqing Oilfield, and about 2% of the pumping units fail to shut down every year. More...
Compared with the traditional cylindrical gear, the tooth line of vh-catt is special. It is arc-shaped on the plane that extends along a cylindrical surface coaxial with the gear, while the tooth lines of other gears, such as spur gears and helical gears, are straight lines and oblique lines....
Using the finite element simulation method to analyze the actual machining of gears, the force of the tool in the actual machining process and the change of other specific cutting performance of the tool can be analyzed. By analyzing the cutting force under different cutting parameters, the influence of...
Variable hyperbolic arc tooth profile cylindrical gear (vh-catt) is a new type of gear which applies arc tooth profile to gear tooth profile. Compared with the existing gear form, its bearing capacity is stronger and transmission performance is better, so it has a broad application prospect. Vh-catt is derived...
The independent variables of the orthogonal test and the natural frequency values of the double circular arc constraint mode solved by workbench software are summarized. The orthogonal test is carried out by SPSS software to analyze the variance of the first-order natural frequency of the double circular arc gear...
Orthogonal test of double circular arc gear is an important mathematical statistical method to study multi factor test. The orthogonal table can quickly find out the best level combination of test factors, understand the importance and interaction of test factors, realize the reasonable and effective arrangement of test factors,...
In order to quickly solve the low order frequency of the constrained mode of double circular arc gear and reveal the sensitivity of the main parameters of the gear to the natural frequency, the constrained mode of double circular arc gear is solved by finite element method; On this...
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...
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...
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...
