Abstract
The invention relates to a non-stepped speed changer, with zero rotational speed ratios. The input axle 11 rotates to drive the connection rod 10 and axle 12; the connection rod 9 pushes the bent axle 8 to realize the oscillating motion of gear 5 which is transformed into the continuous rotation of output gears 3 and 4 along single direction via the gear group; the input axle 11 can be horizontally moved left and right to control the amplitude of oscillating motion of gear 5 to control the rotational speed ratio. The gear group is formed by gears as 1, 2, 3, 4 and the axles as 6 and 7. Wherein, one group of gears of 1 and 2 and the gear of 3 and 4 is single clutch gear with reverse clutch direction. The invention has easy control, high transmission efficiency, big transmission torque, saved energy, 0 rotational speed ratio, lower weight, smaller size, and stable rate between power and volume.
Description
Technical field
The present invention relates to a kind of infinite variable speed implementation method and adopt the stepless speed variator of this method.
Technical background
Existing speed changer comprises gear transmission step change transmission and friction transmision stepless speed-variator, the transmission of gear transmission step change transmission energy is high pulling torque very, the transmission efficiency height, but need shift hunting just can reach comparatively ideal gear ratio, inconvenience, and in shift process the race of engine, the waste energy, speed changer volume and quality are big, complex structure; Friction transmision stepless speed-variator can be realized stepless change, but its drawback is that energy dissipation is big, and driving torque is limited by friction driving.
Summary of the invention
When rotating, input shaft make driven gear do reciprocal rotation by continuous action device, utilize gear train that the reciprocal rotation of driven gear is converted to the continuous rotation of output gear along single direction again, driven gear is made the moving amplitude size decision of reciprocating operation and is proportional to the size of gear ratio.Because the reciprocal rotation amplitude of driven gear can be zero, so can realize zero gear ratio, its maximum (top) speed is than reaching the ratio of wanting by meshing other gear of output gear, so its variator ratio range is 0----N, so this speed changer can save clutch.And when because the effect of system inertia when making the rotational velocity of output shaft greater than rotational velocity that input shaft provided, just is in clutch state between output shaft and the input shaft, the output shaft inertia that can make full use of machinery is rotated further the saving energy like this.
Embodiment
(1) with continuous action device the rotation of input shaft 11 is converted to the reciprocal rotation of gear 5 and the realization of gear 5 reciprocal rotation amplitude sizes.This continuous action device is made of 10,9 12 on connecting rod and bent axle 8.As figure (1) axle 11 are input shafts, and bent axle 8 is fixing with gear 5, and connecting rod 9 usefulness bearings link to each other with axle 12 with bent axle 8 respectively.To do with a be that the conical surface on summit rotates to drivening rod 10 when input shaft 11 rotated, and make axle 12 follow the b point when self rotates and move in a circle that connecting rod 9 makes bent axle 8 do reciprocal rotation by push-and-pull action, thereby gear 5 also done reciprocal rotation.Come the back and forth amplitude size of rotation of control gear 5 by left and right sides translation shaft 11.When input shaft 11 levels move to right when being in figure (2) state, input shaft rotates, and 12 on axle was done self and rotated this moment, and 9 pairs of axles 8 of connecting rod do not have push-and-pull action, and gear 5 is not done reciprocal rotation; When the input shaft horizontal left was in figure (3) state, this moment, connecting rod 10 was in plumbness with axle 11, and axle 12 is followed the radius maximum that the b point moves in a circle, the push-and-pull amplitude maximum of 9 pairs of bent axles 8 of connecting rod, the reciprocal rotation amplitude maximum of gear 5.Here must guarantee the length of bc length less than ab, ab and bc length difference are less than the radius of gyration of bent axle 8, and the length of bc is greater than zero.
(2) the reciprocal rotation of gear 5 is converted to output gear 3 and 4 separately along the continuous rotation of single direction with gear train.As scheming (1) this gear train by gear 1,2,3,4, axle 6,7 is formed, make one group to be the one-way clutch gear in gear 1,2 and the gear 3,4, one group is ordinary gear, the internal structure of one-way clutch gear is identical with the internal structure of automobile overrunning clutch or bicycle rear axle flywheel, and essential simultaneously their clutch direction of assurance is opposite.Here we are the one-way clutch gear with 1,2,3,4 for ordinary gear be example.Gear 1,2 clutch directions are opposite, and gear 3 is identical with 4 radiuses and fixing and meshing with axle 6,7 respectively, and gear 1 is identical with 2 radius but less than the radius of gear 3 and 4,5 whiles of gear are meshing with gear 1,2, and gear 1 and 2 is not meshing.Gear 1 is in clutch state when rotating along clockwise direction, the edge is in lockup state and drives axle 6 and gear 3 rotation in the counterclockwise direction together when rotating counterclockwise; Gear 2 is in clutch state when rotating counterclockwise, it is in lockup state and drives axle 7 and gear 4 rotation along clockwise direction together when rotating along clockwise direction.
When gear 5 when the A direction is rotated: gear 2 is in clutch state, and gear 1 is in lockup state, and this moment, gear 1 drove axle 6 and gear 3 rotates together in the counterclockwise direction, and gear 3 driven gears 4 rotate.
When gear 5 when the B direction is rotated: gear 1 is in clutch state, and gear 2 is in lockup state, and this moment, gear 2 drove axle 7 and gear 4 rotates together along clockwise direction, and gear 4 driven gears 3 rotate.
Realized gear 4 transmitting gear 3 rotation continuously in the counterclockwise direction always continuously along clockwise direction always like this, the reciprocal rotation conversion that makes gear 5 is for output gear 3 and the 4 continuous rotations along single direction, and the centre does not have power to lose generation.Simultaneously because gear 5 is meshing with gear 1 and 2, so that gear 5 is done reciprocal rotation amplitude once is big more, the angle that output gear 3 and 4 turns over is just big more, has realized that the amplitude sizes of utilizing gear 5 back and forth to rotate control and be proportional to the purpose of gear ratio size.

1. gear drive
2. stepless fully
3. has 0 rotating ratio
4. simple in structure, quality and volume are little
