Gear.
The present apparatus by two eccentric free wheels with sliding slot combine between 90 degree of angle.It is mainly responsible for the input of power and limits planet
The moving radius of wheel allows planetary gear to make concentric motion when being overlapped with eccentric free wheel axle center and flies to abaxial around eccentric
Make to convert between the planetary motion of maximum radius in wheel axle center.The moving radius of planetary gear is controlled with hydraulic device, realizes that power passes
The speed and torque sent change.And angle between 90 degree of two eccentric free wheels, then the steady and uninterrupted of power transmission is realized, is made
Power endlessly can be transmitted steadily.The moving radius of two planetary gears must be consistent, otherwise can become always by
That group of big mechanism of moving radius undertakes transmission power.And power not as good as two groups work at the same time when it is steady, coherent, also be easy to cause
The abrasion of device is unbalanced.
Planetary gear and transmission arm of wagging the tail, rack are mainly responsible for the transmission of power, and tooth is changed into the planetary motion of planetary gear
The section stretching motion of item.The planetary motion diameter of planetary gear is the flexible stroke of rack, when planetary gear and eccentric free wheel are in
When now concentric, planetary gear actually stationary state.As planetary gear is detached from eccentric free wheel axle center, and make planetary motion around the axle center
When, the planetary motion diameter of planetary gear is exactly the stroke of rack stretched with contracting.It gets over the position that planetary gear deviates eccentric free wheel axle center
Greatly, its planetary motion diameter is bigger, and bigger to the flexible stroke of rack, year-on-year movement velocity is faster.And speed with
Torque is inversely proportional, and speed is faster in the case that input power speed is constant, and torque is smaller；And the bigger relative velocity of torque is more
Slowly, changed according to the moving radius size of planetary gear.
Upper unidirectional flywheel undertakes power output when rack contracting, converts it to rotate clockwise.Unidirectional flywheel is then held down
Power output when load rack is stretched, converts it to rotate clockwise.After unidirectional flywheel completes the flexible power conversion of rack, by
Transmission shaft passes to output gear output.
As long as transmission ratio theoretically input power and parts license, it may be implemented zero to infinity.This be it is current other
The advantage that speed change gear cannot possess.
The utility model and embodiments thereof are described above, this description is no restricted, shown in attached drawing
Also be the utility model one of embodiment, actual structure is not limited to this.All in all if this field
Those of ordinary skill is enlightened by it, without deviating from the purpose of the present invention, not inventively design with
The similar frame mode of the technical solution and embodiment, all should belong to the protection range of the utility model.
