Optimum determination of partial transmission ratios of coupled planetary gearboxes For the low-speed row of the coupled planetary gearbox (see Figure 1), the design equation for the pitting resistance can be written as follows [8]: (1) In the above equations, , , are coefficients which consider the effects of the gear material, contact surface shape, and contact ratio of the first gear unit when calculate the pitting resistance; is the torque of the driving shaft (Nm), is allowable contact stresses of the low-speed row of the planetary gearbox.
