| Summary: | Taking two kinds of typical involute splines applied in the power split system as the research object，the theoretical analysis models of the load distribution factor in the tooth direction are established respectively，and the effects of load position，torque distribution and torsional rigidity of splines on the load distribution in the tooth direction are studied. The results show that，for the first kind of involute spline pair，with the increase of load distribution position and load distribution ratio，the maximum load distribution factor first decreases and then increases. There are optimal load position and optimal load distribution ratio to minimize the maximum load distribution factor，with the reduction ratio of 56.67% and 51.83% respectively. When the left torsional stiffness is 450×10<sup>6</sup> N/rad and the right torsional stiffness is 522×10<sup>6</sup> N/rad，the maximum load distribution factor reaches the minimum value of 2.08，and the maximum value increases by 31.8% compared with the minimum value. For the second involute spline pair，the maximum load distribution factor increases gradually with the increase of the left torque position，and the increase proportion is 14.36%，the influence of load distribution on the maximum load distribution factor is very small. With the increase of torsional rigidity，the maximum load distribution factor increases by 16.86%. |
