Such as Fig. 6, web wheel 3 is fixed with clamping and fixing device, then web wheel stops operating, and the now revolution of planet axis stops Only, using any one in foreign steamer 1,2,4,5 as driving link, then now can only rotation so that form dead axle between each gear Train.
2) 3K types fixed shaft gear train (removing 2 or 4 big foreign steamers)
Such as Fig. 7, web wheel 3 is fixed with clamping and fixing device, then web wheel stops operating, and the now revolution of planet axis stops Only, using any one in foreign steamer 1,5 as driving link, then now planet axis can only rotation so that it is fixed to be formed between each gear Axle train.
3) 2K types fixed shaft gear train (remove 2 and 4 big foreign steamers, leave 1,3,5)
Such as Fig. 8, web wheel 3 is fixed with clamping and fixing device, then web wheel stops operating, and the now revolution of planet axis stops Only, using any one in foreign steamer 1,5 as driving link, then now planet axis can only rotation so that it is fixed to be formed between each gear Axle train.
1) 2K-H types cyclic train
Pattern 1：Such as Fig. 9, remove big foreign steamer 1,2 and (similarly, remove big foreign steamer 4,5), then turnover is formed between remaining components Train.1 or 2 are fixed with fixture, then now form for planetary gear train；When not using fixture, spider gear is monolithically fabricated System.
Pattern 2：Such as Figure 10, when 2.4 big foreign steamers are removed, foreign steamer 1 or 5 is fixed using fixture, then black box structure Into planetary gear train.
2) 3K types cyclic train
When removing 2 (or 4) big foreign steamer, black box may be constructed 3K type cyclic trains
Pattern 1：Such as Figure 11, when foreign steamer 4 is fixed, planet axis can also can both be revolved round the sun with rotation around main shaft, It is monolithically fabricated 3K type cyclic trains.
Pattern 2：Such as Figure 12, when foreign steamer 5 is fixed, planet axis can also can both be revolved round the sun with rotation around main shaft, It is monolithically fabricated 3K type cyclic trains.
Compound gear train is demonstrated
Evil spirit wheel may be constructed 4 kinds of compound gear trains altogether, and its is specific as follows：
1) compound gear train 1
Such as Figure 13, fixed gear 1, other 4 wheels rotate, the existing rotation of planet axis, and are revolved round the sun around central principal axis.This When gear 4,7,5 and 3 between form differential speed gears, form planetary gear train between gear 2,6,1 and web wheel 3.Overall structure Into compound gear train.
2) compound gear train 2
Such as Figure 14, fixed gear 2, other 4 wheels rotate, the existing rotation of planet axis, and are revolved round the sun around central principal axis.This When gear 4,7,5 and 3 between form differential speed gears, form planetary gear train between gear 2,6,1 and web wheel 3.Overall structure Into compound gear train.
3) compound gear train 3
Such as Figure 15, fixed gear 4, other 4 wheels rotate, the existing rotation of planet axis, and are revolved round the sun around central principal axis.This When gear 2,6,1 and web wheel 3 between form differential speed gears, form planetary gear train between gear 4,7,5 and 3.Overall structure Into compound gear train.
4) compound gear train 4
Such as Figure 16, fixed gear 5, other 4 wheels rotate, the existing rotation of planet axis, and are revolved round the sun around central principal axis.This When gear 2,6,1 and web wheel 3 between form differential speed gears, planetary gear train, overall structure are formed between gear 4,7,5 and 3 Into compound gear train.
The specific embodiment of invention is these are only, but the technical characteristic of the present invention is not limited thereto.It is any with the present invention Based on, to realize essentially identical technique effect, made ground simple change, equivalent substitution or modification etc., all it is covered by Among protection scope of the present invention.
