The main components of the continuously variable transmission comprise an input shaft, an input middle wheel, a reversal road wheel, a speed reducing road wheel, a road wheel shaft, a road wheel frame, a procession middle wheel, a driving middle wheel, a rigid joining sleeve, a driving frame, a driving wheel shaft, a driving road wheel, a tooth ring, an output frame, an output shaft and an enclosure; the reversal road wheel and the speed reducing road wheel form a bigeminy roller planetary gear; the torque is changed by the autorotation movement of the bigeminy roller planetary gear and the revolution motion under the comprehensive effect of three groups of planetary gear rows, thus when the maximum torque is output, simultaneously the maximum rotation speed can also be output after the loading is reduced, the mechanical continuously variable transmission function is finished reliably, and the continuously variable transmission has the advantages of simple structure, low cost and high continuous bearing force of the transmission ratio, is safe and reliable, and has long service life.
Description
Technical field
The present invention relates to a kind of mechanical speed changer, relate in particular to a kind of roller planet gear stageless speed variator that is used for transmission system with roller planetary pinion conversion moment of torsion.
Background technique
At present the automatic Transmissions Technique of more use is an automatic transmission technology with fluid torque converter and epicyclic train combination on automobile, but it has significant disadvantages: velocity ratio is discontinuous, hydraudynamic drive efficient is lower, complex structure, safeguard inconvenience, another 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, transmitted power is limited, and the cost long-life is short, and its control system is quite complicated, cause supplementary costs to increase, 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 the roller planet gear stageless speed variator that the roller planetary gears is made, can be directly according to load variations when work, fully automatically, carry out stepless change moment of torsion variable speed running, and need not the liquid electric servo, 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 roller planet gear stageless speed variator, and it carries out stepless change moment of torsion variable speed running fully automatically in the course of the work directly according to load variations and the conversion gear.
The present invention is achieved in that in Fig. 1: roller planet gear stageless speed variator main parts size is by input shaft 1, take turns 2 in the input, counter-rotating road wheel 3, deceleration road wheel 4, road wheel axle 5, road wheel frame 6, take turns 7 in the driving, take turns 8 in the precession, just the connection cover 9, bogie 10, live axle 11, drive road wheel 12, gear ring 13, output frame 14, output shaft 15, casing 16 is formed, its structure is: input shaft 1 is with output shaft 15 coaxial lines and by casing 16 supportings, make just to be associated with on the input shaft 1 and take turns 2 in the input, counter-rotating road wheel 3 has just joined with deceleration road wheel 4, road wheel frame 6 its fronts (before establishing input end and being, output terminal is the back) circumferentially all equal portions road wheel axle 5 more than two is installed, with the counter-rotating road wheel 3 of quantity such as road wheel axle 5 and deceleration road wheel 4 promptly by 5 supportings of road wheel axle, after wheel 7 has just joined in road wheel frame 6 its center portions, back and the driving, be sleeved on the firm cover 9, just wheel 8 has just joined in connection cover 9 its front ends and the precession, its rear end and bogie 10 just have been sleeved on the position of protracting of output shaft 15 behind the connection, the circumferentially equal equal portions in the front of bogie 10 are equipped with the live axle 11 more than two, with the driving road wheel 12 of quantity such as live axle 11 promptly by live axle 11 supportings, output frame 14 its fronts and gear ring 13 have just joined, its center portion and output shaft 15 have just joined, each gear meshing relation is: wheel 2 and 3 engagements of counter-rotating road wheel in the input, constitute first group of epicyclic gear train, wheel 8 constitutes second group of epicyclic gear train with 4 engagements of deceleration road wheel in the driving, wheel 7 constitutes the 3rd group of epicyclic gear train with driving road wheel 12 and gear ring 13 engagements in the driving.In Fig. 2: according to roller planet gear stageless speed variator shown in Figure 1, under the constant situation of its main parts size and most of structure, the roller planet gear stageless speed variator can be simplified, the output frame 14 that is about among Fig. 1 saves, wheel 7 and the directly firm connection of output shaft 15 directly just join road wheel frame 6 and gear ring 13 in will driving.
Its working principle is: in Fig. 1, when input shaft 1 forward rotation (establishing its sense of rotation is forward), wheel 2 drives the dual gear roller backward rotation that is formed with deceleration road wheel 4 firm connection by counter-rotating road wheel 3 in the input, wheel 8 promptly drives bogie 10 by just joining cover 9 in the precession after slowing down, live axle 11 is just changeing, thereby driving output shaft 15 with Maximum Torque is just changeing, meanwhile also promoting road wheel frame 6 is just changeing, this is the output of speed changer Maximum Torque, along with the load required torque reduces gradually, by counter-rotating road wheel 3 and deceleration road wheel 4 just the dual gear roller that forms of connection then in driving wheel 8 begin roll forwards and form revolution, its rolling advocates to come self-driven road wheel 12, and the whole component revolution rotating speeds that are clamped between input shaft 1 and the gear ring 13 are also accelerated thereupon gradually, and carry out the transition to identical gradually with the rotating speed of input shaft 1, be 1 to 1 output, thereby finish velocity ratio continually varying stepless shift function.
Roller planet gear stageless speed variator of the present invention, because the roller planetary gear construction is used in innovation, make its can output Maximum Torque in, after reducing, load can also export maximum speed, thereby it is finished 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.
