Research status of gear strength analysis methods

The gear strength calculation is based on the calculation formula proposed by and. Various coefficients are used to correct the material strength and gear load, and the influence of gear accuracy is considered. The calculation method close to the critical load is the main method. There are still many...

Tooth surface contact analysis of hypoid gear

Figure 1 shows the gear pair meshing coordinate system, S1 and S2 are the dynamic coordinate system of small wheel and large wheel respectively, SS is the gear tooth meshing coordinate system, and H is the axial assembly distance, Σ Is the axle intersection angle, and V is the...

Finite element analysis of internal modified gear

Because the working condition of the gear is the same when the inner gear plate and the outer gear contact meshing, the finite element analysis effect is the same, so two pairs of meshing gears are selected for finite element analysis. The hexahedral mesh is used, with 175179 nodes....

Dynamic analysis of internal modified gear

According to the mechanical model of internal gear pair and gear dynamic model, the dynamic model of internal modified gear in this paper is created, as shown in Figure 1. In Figure 1, K is the generalized contact stiffness; E is the gear transmission error; C damping coefficient of...
