two stage gearbox in mining machine

A two-stage gearbox or a three-stage gearbox can be achieved by simply increasing the length of the ring gear and with serial arrangement of several individual planet stages. A planetary gear with a ratio of 20:1 can be manufactured from the individual ratios of 5:1 and 4:1, for example

    Mar 29, 2021 Mar 29, 2021 The resulting gear ratio is the product of the gear ratios of each stage. For example, a two-stage gearbox consisting of one stage with a 5:1 gear ratio and a second stage with a 3:1 gear ratio provides an output ratio of 15:1 (5 x 3), so the torque delivered to the load is 15 times higher the torque provided by the motor — not including transmission losses — and the speed delivered to the load is 1/15 the
