The invention relates to a mechanical speed changer, in particular to a precession frame planetary gear stepless speed changer which a precession frame planetary gear mechanism is adopted in a drive system to push output. The main parts of the stepless speed changer comprise an input shaft (1), an input wheel (2), a precession wheel (3), a push wheel (4), a transmission ring (5), a travelling wheel shaft (6), a precession frame (7), an output gear ring (8), an output disc (9), an output shaft (10), an auxiliary travelling wheel shaft (11), a balance wheel (12), a third wheel (13), an auxiliary push wheel (14) and a machine case (15). With the adoption of the stepless speed changer, the precession wheel (7) can automatically rotate with the output gear ring (8), meanwhile, the output gear ring (8) is further pushed, so that the torque of the small-diameter input wheel (2) can be applied to the output gear ring (8) no matter how much the rotational speed of the large-diameter output gear ring (8), and the function of mechanical stepless speed changing is reliably fulfilled. Moreover, the stepless speed changer is simple in structure and low in cost, is safe, reliable and durable, and has high transmission ratio and continuous bearing capability.
Description
Technical field
The present invention relates to a kind of mechanical speed changer, relate in particular to and adopt precession frame planetary gears in a kind of transmission system and promote the precession frame planet gear stageless speed variator of output from the precession characteristic with it.
Background technique
The automatic Transmissions Technique of more use is the automatic transmission technology with fluid torque converter and epicyclic train combination on automobile at present, but it has significant disadvantages: velocity ratio is discontinuous, and hydraudynamic drive efficient is lower; Complex structure is safeguarded inconvenience, a kind of in addition stepless change (CVT); Its adopts metal driving belt and the variable driven wheel of the working diameter incompatible transferring power that matches, but the CVT weakness is that the metal tape bearing capacity is little, and transmitted power is limited; And the cost long-life is short; Its control system is quite complicated, causes supplementary costs to increase, and can only be used for car at present.Therefore, develop a kind of safe and reliable, simple in structure, easy to process and cheap stepless speed variator, just become mechanical industry urgent problem recent decades.The present invention initiates precession frame planetary gears and promotes the precession frame planet gear stageless speed variator of output from the precession characteristic with it; When work directly according to load variations; Fully automatically carry out stepless change moment of torsion variable speed running, the present invention does not see homogeneous structure product and related data both at home and abroad.
Summary of the invention
Problem to be solved by this invention provides a kind of precession frame planet gear stageless speed variator, and it is in operation and adopts precession frame planetary gears and promote output with it from the precession characteristic, carries out stepless change moment of torsion variable speed running fully automatically.
The present invention is achieved in that in Fig. 1: precession frame planet gear stageless speed variator main parts size comprises input shaft 1, wheel for inputting 2, precession wheel 3, promotion wheel 4, transmission circle 5, road wheel axle 6, precession frame 7, output gear 8, output disc 9, output shaft 10, secondary road wheel axle 11, stabilizer 12, third wheel 13, secondary wheel 14, casing 15 compositions of promoting; Its structure is: input shaft 1 is with output shaft 10 coaxial lines and by casing 15 supportings; Just be associated with wheel for inputting 2 on the input shaft 1; Input shaft 1 has precession frame 7 with output shaft 10 upper supports; Road wheel axle 6 and secondary road wheel axle 11 just have been associated with on the precession frame 7; Road wheel axle 6 upper supports have precession wheel 3 and promote wheel 4; Precession wheel 3 has just joined with promotion wheel 4; Transmission circle 5 is sleeved on wheel for inputting 2 and takes turns on 3 with precession; Output gear 8 has just joined with output disc 9 and output shaft 10; Third wheel 13 is by output shaft 10 supportings; Stabilizer 12 is supported by secondary road wheel axle 11 with the secondary wheel 14 that promotes; The meshing relation of each gear and circle is: engagement in engagement in wheel for inputting 2 and the transmission circle 5, precession wheel 3 and the transmission circle 5, constitute the front row and rotate epicyclic gear train in the same way, promote engagement in wheel 4 and the output gear 8, secondaryly promote engagement in wheel 14 and the output gear 8, promote wheel 4 and secondaryly promote between the wheel 14 through third wheel 13 engagement, arrange major-minor after the formation and promote epicyclic gear train.
In precession frame planet gear stageless speed variator shown in Figure 1: its transmission circle 5 can be ring gear, also can be Transmitted chains, driving belt.
Precession frame planet gear stageless speed variator working principle is: at Fig. 1; Input shaft 1, wheel for inputting 2, precession wheel 3, promotion wheel 4, transmission circle 5, road wheel axle 6, precession frame 7 one of common formation can be followed the precession frame planetary gears that promotes output gear 8 automatically; This is the invention core technology of precession frame planet gear stageless speed variator, and precession frame 7 is followed the moment of torsion of output gear 8 automatically, be that contact pointss are fulcrum in wheel 4 and the output gear 8, take turns 3 contact pointss with transmission circle 5 and precession to promote is that force position is obtained; When power is rotated with promotion wheel 4 and then desire promotion output gear 8 through transmission circle 5 drive precession wheels 3 by wheel for inputting 2; To at first promote precession frame 7 and rotate, thereby can make precession frame 7 when following output gear 8 rotations automatically, output gear 8 is done further to promote; So just can be with the torsion of the wheel for inputting 2 of minor diameter; No matter large diameter output gear 8 rotating speeds how much, can both add on it, thereby accomplish the mechanical stepless speed-changing function reliably.
Precession frame planet gear stageless speed variator of the present invention because precession frame planetary gears is used in innovation, makes it can be in the output Maximum Torque;, load can also export maximum speed after reducing; Thereby it is accomplished the mechanical stepless speed-changing function reliably, thereby simple in structure, cheap; Velocity ratio continuous bearing power is big, and the safe and reliable spreadable life is long.
