Planetary Gearbox for Trucked and wheeled cranes

Wheel drive, single reduction1. The coupling (1) rotates in the direction of rotation of the motor shaft (CW)2. Input shaft (2) splined to coupling (CW)3. The sun gear (3) is splined to the input shaft (CW)4. Planetary gear (4) rotates relative to sun gear (CCW)5. Planetary gear (4) drives ring gear (5) in the same direction (CCW)6. Ring gear (5) connects to the hub (6), hub rotates (CCW)7. Hub (6) attached to wheel/rim, wheel rotation (CCW).Wheel Drive, Double Reduction1. Coupling (1) rotates in the direction of motor shaft rotation (CCW)2. Input shaft (2) splined to coupling (CCW)3. Primary sun gear (3) splined to the input shaft (CCW)4. Planet gears (4) rotate opposite sun gear (CW)5. Primary carrier (5) rotates opposite planet gears (CCW)6. Secondary sun gear (6) attached to the primary carrier (5) (CCW)7. Secondary planet gears (7) rotate opposite sec. sun gear (6) (CW)8. Ring gear (8) rotates in the same direction as sec. planet gears (7) (CW)9. Hence driving the hub (9) (CW)10. Hub (9) attached to wheel/rim (CW)Shaft/Spindle Output, Single Reduction1. Sun gear (1) rotates in the direction of motor shaft rotation (CW)2. Planet gears (2) rotate opposite sun gear (1) (CCW)3. Carrier (3) is driven in the same direction as the sun gear (1) (CW)4. Spindle or shaft (4) is splined to the carrier (3); therefore, it rotates (CW)Shaft/Spindle Output, Double Reduction1. Primary sun gear (1) rotates in the direction of motor shaft rotation (CCW)2. Primary planet gears (2) rotate (CW)3. Primary carrier (3) driven (CCW)4. Secondary sun gear (4) attached to the primary carrier (3) (CCW)5. Secondary planets (5) rotate opposite secondary sun gear (4) (CW)6. Secondary carrier (6) driven (CCW)7. Output spindle or shaft (7) splined to secondary carrier assembly (6) (CCW)
