Load sharing factor of vehicle gear planetary drive

Under gear 1-8, the load-sharing coefficient of the loaded planetary row is shown in the figure, in gear 1-4, the planetary row K2 is loaded, while in gear 5-8, the planetary row K1 is loaded and rotates as a whole.

It can be seen that the inner and outer engagement load-sharing characteristics of planetary row K2 under gear 1-4 are better than those of planetary row K 1 with gear 5-8, which indicates that the load-sharing characteristics of planetary drive are poor under the condition of overall rotation.

Among them, planetary row K 2 has the best load sharing characteristics in 2nd gear and 4th gear, while planetary row K1 has the worst load sharing characteristics in 7th gear and 8th gear.
