As an important part in sliding-limiting differential, the variable ratio noncircular bevel gears can increase the locking factor of the bevel gear differential and improve the vehicles’ off-road capability in transit. At present, this differential has become a study hotspot that many researchers are working over because of its compact structure, cheap cost, good assembly and perdurable capability. In order to get the bevel gear’s processing accuracy, this paper introduced the generating process of the bevel gear’s CMM measuring path, probed the similarity in motion between spherical cutter’s CNC machining and CMM measuring, and then simulated and analyzed the bevel gear’s CMM measuring path by power mill in use of NC authentication method, which provided a reference for the choice of complex surfaces’ measuring methods.

The aim in this paper is to analyze tooth surface contact stress and transmission errors, verify existence of tooth end effect and discuss symmetry of symmetrical bevel gear differential (SBGD), etc. With this aim, a 3D elastic FE model of SBGD is established under the ANSYS software environment and its meshing characteristic is determined. Starting from here, by analyzing stress and circumferential displacement of tooth, the phenomena of stress concentration is acquired; the distribution of tooth surface contact stress is studied; tooth end effect is confirmed; transmission error is assessed. The analysis is ended by assessing the symmetry of SBGD. Research results provide valuable guidelines for the design of SBGD. The developing model method proposed in this paper makes it possible to study other complex gear mechanisms such as planetary gear system.

The vector form intrinsic finite element (VFIFE) method is springing up as a new numerical method in strong non-linear structural analysis for its good convergence, but has been constricted in static or transient analysis. To overwhelm its disadvantages, a new damping model was proposed: the value of damping force is proportional to relative velocity instead of absolute velocity, which could avoid inaccuracy in high-speed dynamic analysis. The accuracy and efficiency of the proposed method proved under low speed; dynamic characteristics and vibration rules have been verified under high speed. Simulation results showed that the modified VFIFE method could obtain numerical solutions with good efficiency and accuracy. Based on this modified method, high-speed vibration rules of spiral bevel gear pair under different loads have been concluded. The proposed method also provides a new way to solve high-speed rotor system dynamic problems.
