Taking the hypoid gear of the drive axle as the research object, the mechanism of fatigue and noise generation of the drive axle gear is deeply studied by means of simulation and experiment. From the perspective of the overall drive axle, the bending stress, bending fatigue life and noise...
The meshing stiffness of hypoid gears can be obtained by substituting the data of gear force, static transmission error and load transmission error into the formula. As shown in the figure, the meshing stiffness calculation results show that the meshing stiffness of hypoid gears changes periodically. The change period...
Virtual assembly is to determine the relative position between models and complete model assembly through the reference and link relationship between parts. First, the solid models of the driven wheel and the driving wheel are established, and then the solid assembly is carried out according to the installation position....
In order to analyze the hypoid gear alignment, an accurate geometric model must be established to lay a foundation for the following analysis. At the same time, the influence of various errors on hypoid gear transmission is analyzed by applying various loads and moments at different assembly error positions,...
The noise prediction model of Hypoid Gear Meshing Based on drive axle is established. Firstly, the classical 14 DOF lumped parameter model of hypoid gear is analyzed. Then the direction cosine, direction rotation radius, time-varying meshing stiffness and meshing parameters are calculated by ABAQUS method, and the changes of...
Conduct contact analysis (LTCA) on the hypoid gear under load. The resistance torque applied at the output end of the large gear is 9000nm, as shown in Fig. 1 (a), which is the change process of single gear meshing force. The definition of surf-i is the same as that...
ZHY gear provided the part drawing and assembly drawing of the hypoid gear of the main reducer of a certain vehicle. According to the design requirements of the drawing, the tooth ratio of the gear is 8 / 41. The three-dimensional solid model of the hypoid gear is established...
Hypoid gears are widely used in automobile, aircraft, ship, machinery, high-precision processing equipment and other fields. Its transmission has the characteristics of high efficiency and stability, and can withstand large loads. The demand is quite large. At present, China’s hypoid gear manufacturers are relatively backward in technology. They mainly...
The time-varying transmission error and meshing stiffness of the hypoid gear of the drive axle are directly related to the noise radiation of the drive axle. The influence factors of time-varying transmission error of drive axle hypoid gear are studied. Firstly, the effects of different loads on static transmission...
The hypoid gear of the micro car main reducer is processed on the hypoid gear milling machine. The processing principle of Gleason machine tool is shown in Figure 1. Y2250 and Y2280 machine tools are designed according to the principle of “imaginary flat top gear”. That is to say,...
