Specific works process:
The characteristic utilizing planet circular system degree of freedom to be 2, reaches speedup and the two kinds of motion moulds that slow down by the different parts of constraint
Formula.Wrench body is that three groups of planetary set are composed in series, and the speed reducing ratio of retarded motion pattern is that three groups of planetary set often organize speed reducing ratio
Seizing the opportunity, total reduction ratio is about about 60, and increases step by step from one group to three group according to practical situations module, with
Adapt to the moment of torsion of required transmission.One group of two groups of planetary set locking during speedup motor pattern, three groups of planet output group work, speed increasing ratio
It is about 3.
Line shaft part is carried out hole axle from power shaft 1 with output shaft 13 and coordinates, line shaft fix screw 12 and connect.Power
It is inserted in the first external splines set 3 on power shaft 1 in axle to be fixed by the first circlip 2, output shaft 13 is inserted in the second external splines
Set 18 is fixed by the second circlip 17.According to order successively by one group of two groups of three groups of planetary set tandem compound, it is inserted in line shaft,
Load onto upper end cover 11 and bottom end cover 4,4 unit bolt nuts 10 fix.
Slowing-down structure scheme:
As it is shown in figure 1, operating position is retarded motion state, third-level planetary group internal gear 9 and upper end cover 11 are by outside second
Spline housing 18 links together, and makes third-level planetary group internal gear 9 fix with upper end cover 11.Now power shaft 1 is by the 3rd spline
Connecting with input sun gear 31, power is transferred to input sun gear 31 by power shaft 1 and is transferred to primary planet wheel 5, is transferred to one
Level planet carrier secondary solar gear 32, is transferred to third-level planetary frame 34 by that analogy, is transferred to output shaft 13 and exports.
Speedup organization plan:
Compare and move up a position as in figure 2 it is shown, operating position is speedup kinestate, relatively slowing-down structure for line shaft
Putting, now third-level planetary group internal gear 9 and upper end cover 11 are disconnected state, and the second external splines set 18 enters the interior of upper end cover 11
In splined hole.The 3rd spline on power shaft 1 and input sun gear 31 separate, and the first external splines set 3 on power shaft 1 is by lower end
Lid 4 is connected fixing with input sun gear 31, now until three grades of sun gears 33 of secondary planet frame are all lockup state.Power shaft
First spline of 1 upper end is connected with third-level planetary frame 34, the second spline of output shaft 13 lower end and third-level planetary group internal gear 9
Connect.Now power is transferred to third-level planetary frame 34 by power shaft 1 input and is transferred to third-level planetary wheel and 8 is transferred to third-level planetary group
Internal gear 9 is transferred to output shaft 13 and exports.
Crank structure scheme:
As shown in Figure 4, crank combination is by rocking arm 25,1 the 3rd pin 27 of 28,1 handle of 1 band side's mortise, 1
Sleeve 26 forms with 1 spherical nut 24.Sleeve 26 is coordinated with handle 25 and is fixed by spherical nut 24.Handle is combined through
3rd pin 27 is connected with rocking arm 28.One end of rocking arm 28 band side mortise is coordinated with the square tenon of wrench body power shaft 1.
Output tube-in-tube structure scheme:
Such as Fig. 4, sleeve group is made up of with 1 sleeve 16 14,1 nigger 15 of delivery of 1 band side's mortise.Lengthen
Sleeve 15, for choosing to install parts, can lengthen outfan.
Pole structure scheme:
Such as Fig. 5-6, strut group is added with 1 by strut 29,2 the first pins 19 of 20,1 strut slippery fellow of 1 band chute
Long strut group forms, and wherein lengthens strut group and is made up of with 2 the second pins 22 23,2 toes 21 of 1 extension bar.Strut 20
It is connected by the first pin 19 with wrench body upper end cover 11 projection so that it is swing fortune may only be done with the first pin 19 for the center of circle
Dynamic, strut foxy 29 is connected by the 4th pin 30 with strut 20, makes strut slippery fellow 29 can do along strut 20 with orthogonal strut 20
Displacement slides, it is simple to adjust position.Extension bar 23 and 2 toes 21 are by 2 the second pin 22 fixed Combination, and two toes can
Close strutting conjunction.Strut slippery fellow 29 slides into inward insert coaxial with strut 20 of edge connect extension bar 23 simultaneously and make its strut
20 lengthenings can be using ground as support.
Should be appreciated that specific embodiment described above is only used for explaining the present invention, be not intended to limit the present invention.By
What the spirit of the present invention was extended out obviously changes or changes among still in protection scope of the present invention.
