Embodiment

For further setting forth the utility model is to reach technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, to according to its embodiment of drive unit, structure, feature and the effect thereof that the utility model proposes, describe in detail as after.

See also Figure 1 and Figure 2, the preferred embodiment of the utility model drive unit comprises that a housing unit 10, one are installed in the power source 20 on this housing unit 10, a pinion gear unit 30 and a gear unit 40 that is installed in this housing unit 10 that is installed in this housing unit 10.

This housing unit 10 has the second fixed shell block 13 of central siphon seat that one first shell block 11 that is hollow tube-shape, one and this first shell block 11 be oppositely arranged 12, and this central siphon seat 12.

The power source 20 of present embodiment is a motor, and is installed in first shell block, 11 1 sides of this housing unit 10, and has one and stretch the axle 21 that is located at these first shell block, 11 inside

This pinion gear unit 30 has a pinion gear 32, that extends and be subjected to the sun gear 31 of these axle 21 interlocks, three intervals to be provided with and to be engaged on these sun gear 31 outsides along first axle L1 and is engaged on the ring gear 33 of aforementioned pinion gear 32 outsides and the support 34 that 32 pivots of an aforementioned pinion gear of confession link.

This sun gear 31 is to be installed on this axle 21.

This ring gear 33 is to be hollow and annular and for internal gear, and is installed in 12 of this first shell block 11 and this central siphon seats.

This support 34 has a main body 341, one and is installed in fixed plate 342 on this main body 341, most along this first axle L1 and is parallel to this first axle L1 and wears axle part 343 to this fixed plate 342 and one by this main body 341 and be installed in rotating shaft 344 on this main body 341 along this first axle L1.342 of this main body 341 and this fixed plates produce three spaces 345 that uniformly-spaced are provided with, and aforementioned axis part 343 is to pass in this space 345.And aforementioned pinion gear 32 is mounted in the aforesaid space 345, and utilizes most shafts to hold 321 to be the rotatable earth's axis and to be located on the part 343, and is engaged on 33 of this sun gear 31 and this ring gears.
