The gauge member that each parts is made with metal, elastomeric material respectively among the present invention, the skilled manpower can be by Fig. 1-12 Assembling Production.Working process of the present invention is made up of positive reverse gearwheel case, these two parts of planet gear stageless speed variator.Positive reverse gearwheel case realizes that positive reverse gear selects, and when gear (7) and internally toothed annulus (6) when overlapping, gear is in Neutral Position, and just the reverse gearwheel case is in the state of quitting work; Make shift fork (117) on the axle (116) stir internally toothed annulus (6) and gear (7), gear (3) to mesh when connecting when promoting control lever (120) by slide block (118), gear (3) constitutes positive shelves combination with gear (5) engagement, and positive reverse gearwheel case is in positive shelves mode of operation; Make shift fork (117) on the axle (116) stir internally toothed annulus (6) and gear (7), gear (10) to mesh when connecting when promoting control lever (120) by slide block (118), gear (10) constitutes the reverse gear combination by intermediate gear (13) and gear (12) engagement, and positive reverse gearwheel case is in the reverse gear mode of operation.Planet gear stageless speed variator is to adopt the rotation axis type of drive, all advantages of epicyclic reduction gear have been inherited, and it is that stepless speed changing mechanism with two different structures constitutes jointly, therefore it has selectivity arbitrarily, in actual applications, the stepless speed changing mechanism of its two different structures both can constitute a toric transmission separately and also can be on demand constitute a toric transmission with the stepless speed changing mechanism tandem of two same structures, through the experimental set-up test, confirmed that it has the failure-free practicality.Shown in Figure 13 structure: two pitch wheels (41), (42), tooth bar (3 ') and gear (42) engagement, tooth bar (4 ') and gear (41) engagement, constitute an experimental set-up, when the power on acting on tooth bar (4 ') equates with the power that drives tooth bar (3 '), gear (41), (42) do rotation, tooth bar (3 '), move to same direction (4 '), when power that acts on tooth (4 ') and driven wheel (41), (42), when the power of tooth bar (3 ') equates, gear (41), (42) stop rotation, with tooth bar (3 '), (4 ') are together to same direction motion.The condition that makes Figure 13 structure reach above-mentioned work effect is; The direction of power that acts on tooth bar (4 ') is parallel with the direction of the power that drives tooth bar (3 ＇), and promptly two tooth bars (3 '), (4 ') are parallel.Structure and principle of work according to Figure 13, adopt the rotation axis type of drive, just based on common epicyclic reduction gear structure, on each championship of pivoted arm, install a planetary wheel additional, and make pivoted arm, internally toothed annulus is in not stationary state, utilize the input gear and the number of teeth difference of output internally toothed annulus to set required transmitting ratio, this is a kind of organization plan of planet gear stageless speed variator, as shown in figure 14: input gear (1 ') and planetary wheel (41) engagement, planetary wheel (41) and planetary wheel (42) engagement, planetary wheel (42) and internally toothed annulus (65) engagement, force direction (5 '), (6 '), divide folding according to figure, this structure exists two factor that does not possess practicality: difference in torque O
1O
2≠ O

3The direction of application force (5 '), (6 ') are not parallel.Again as shown in figure 15: input gear (1 ') and planetary wheel (41) engagement, planetary wheel (41) and planetary wheel (42) engagement, planetary wheel (42) and internally toothed annulus (65) engagement, force direction (2 '), (7 '), divide folding according to figure, though this structure has solved the parallel problem of force direction, it still exists difference in torque O
1O
2≠ O
1O
3The test of experimental set-up shows: when the power on acting on input gear will be passed through the planet gear drives internally toothed annulus, internally toothed annulus does not only move to same direction with input gear, be that planetary wheel is in rotation on the contrary, generation is the revolution at center around the input gear axis, and the direction and the input gear direction of rotation of its revolution, Figure 14,15 planetary gear construction scheme just can't reach the work effect identical with Figure 13 structure like this, also just can not reach infinite variable speed purpose, not have practicality.From above-mentioned test results, make the planetary gear construction of rotation axis transmission reach infinite variable speed purpose, must possess following two conditions: the direction of application force is parallel; Eliminate difference in torque.The present invention is based on Fig. 15, utilize lever principle to eliminate difference in torque, as Fig. 6,7, shown in 8: by stem gear frame (40), (56), gear (41), (42), axle (47), (55) planetary gear set of Gou Chenging is done as a whole, stem gear frame (40), (56) shaft part on (38), (49) be this single-piece central pivot point of planetary gear set, its method for supporting such as Fig. 1,4,5,6,7,8, shown in 9: the positioning port (30) on the radius arm (29) is enclosed within on the step (35) of stem gear frame (40), spline position card (36) on the step (35) engages with spline position card (31) on the positioning port (30), prevent that stem gear frame (40) from rotating, positioning port (24) on the radius arm (22) is enclosed within on the step (50) of stem gear frame (56), spline position card (48) on the step (50) engages with spline position card (28) on the positioning port (24), prevent that stem gear frame (56) from rotating, roller (59) on the shaft part (38) of stem gear frame (40) is done the support of rolling with the support wheel (61) that is fixed on the input gear axle (9), roller (62) on the shaft part (49) of stem gear frame (56) do to roll supports with the support wheel (64) that is fixed on the input gear axle (9), and with input gear axle (9) on gear (66), internally toothed annulus (65), tep reel gear (67), constitute a planetary gear stepless speed changing mechanism.Show through experimental set-up test, must accomplish following 3 points: gear (41), (42) equal diameters, its center-point should with the central spot of input gear axle (9) on same straight line; Step (35) on roller (59), (62) and stem gear frame (40), (56), the diameter of (50) are equal to or less than two axis holes (37) on the stem gear frame (40), the width between centers of (39); The length of the step (35) of stem gear frame (40), (56), the spline screens (36) on (50), (48) approximates the radius of gear (41).It just can realize stepless change like this, has practicality.As Figure 10,11, shown in 12: by tooth rest (75), (80), gear (70), (73), axle (68), (71), radius arm (74), the planetary wheel fabricate block that pin (78) etc. constitute, its method for supporting is as shown in Figure 1: roller (91), (94) with tep reel gear (67) on support ring (92) engage to do roll and to cooperate, roller (95), (97) engaging the do rolling with disc type support ring (96) cooperates, the planetary wheel fabricate block is supported, and with tep reel gear (67) on gear (98), internally toothed annulus (93) tep reel output shaft (101) constitutes another stepless speed changing mechanism.Although the structure of this stepless speed changing mechanism and previous stepless speed changing mechanism is different, it is poor that it and the former utilize lever principle to eliminate torque equally, and with the former same principle of work is arranged.The experimental set-up test shows that it can realize stepless change.Has practicality.With the stepless speed changing mechanism in front among Fig. 1 is example, when its transmitting ratio is set at 5: 1, its working process is as follows: the moment of torsion of input gear axle (9) input is less than driving five/for the moment of tep reel gear (67) required torque, and stepless speed changing mechanism can not be worked, and is in halted state; The moment of torsion of importing when input gear axle (9) equals to drive five/for the moment of tep reel gear (67) required torque, the planetary wheel fabricate block that is made of stem gear frame (40), (56), gear (41), (42), axle (47), (55), radius arm (22), (29) remains static, rotation is done in gear on the fabricate block (41), (42), at this moment tep reel gear (67) is by setting the transmitting ratio output speed, input gear axle (9) and the rotating speed of tep reel gear (67) and the ratio maximum of moment of torsion; When the moment of torsion of input gear axle (9) input greater than driving 1/5th of tep reel gear (67) required torque, less than 1 o'clock, be used for acceleration/accel greater than 1/5th less than this part moment of torsion of 1, be subjected to the effect of this part moment of torsion, the planetary wheel fabricate block begins to be changed into dynamically by static state, and the gear on the fabricate block (41), (42) are in rotation, generation is the revolution at center around input gear axle (9) axis, and at this moment the rotating speed on input gear axle (9) and the tep reel gear (67) and the ratio of moment of torsion just produce continuous variation; When the moment of torsion of input gear axle (9) input equate with driving tep reel gear (67) required torque, when equaling 1, gear (41), (42) stop rotation, the planetary wheel fabricate block rotates synchronously with input gear axle (9), tep reel gear (67), at this moment the rotating speed on input gear axle (9) and the tep reel gear (67) and the ratio minimum of moment of torsion, promptly 1: 1, so just realize stepless change.
