    Abstract: An axial drive mechanism consisting of a worm gear 16, a first planetary gear system 20 having a carrier 22, helical planet gears 32 in meshing engagement with the worm gear 16 and mounted on the carrier, and a ring gear 38 on the carrier. An electric motor 12 can be used to drive the worm gear and a second planetary gear system 40 can be arranged in a coaxial relation with the first system to achieve a desired gear reduction while retaining the axial arrangement of the drive. The second planetary gear system 40 has planet spur gears 42 arranged about and in meshing engagement with the first ring gear 38 and a stationary ring gear 48 encircling the planet spur gears. The second planetary gear system includes a carrier 46 on which the planet spur gears are mounted and an output pinion gear 50 formed integral with the last mentioned carrier. The stationary ring gear is conveniently formed as part of the housing for the electric motor.
