Two, planet gear stageless speed variator:
According to equation (1-1) and (1-2) as can be seen, planetary gears has two degrees of freedom no matter be single planetary row or double planet wheel rows of mixing.In these three primary elements of sun gear, gear ring and planet carrier, give the certain rotating speed of any one element, the rotating speed of two elements can change continuously in addition; If give two rotating speeds that element is certain, the rotating speed of another element also is certain so; If give two elements can the continually varying rotating speed simultaneously, the rotating speed of another element also may be a continually varying so, and promptly another element may be realized stepless change.
Planet gear stageless speed variator is made up of two planet rows and drive ratio controlling device.Two planets row is with two degrees of freedom transferring power, and one as primary planet row, the secondary planet row of conduct.Any two primary elements of primary planet row connect with two primary elements of secondary planet row respectively or make one or mesh, another element of primary planet row is a driving link, another element of secondary planet row is a driven member, and the rotating ratio of driving link and driven member is exactly a transmission ratio.The maximum transmission ratio of transmission ratio control mechanism controls speed changer and fastest ratio are promptly controlled when velocity ratio reaches maximum value and are no longer increased and can reduce, and no longer reduce when reaching minimum value and can increase.The velocity ratio controlling method is: when velocity ratio maximum value or minimum value, the some element of one-way brake except that driving link and driven member perhaps limits the rotating ratio scope of certain two element of planet row.
If do not consider losses such as friction, according to law of conservation of energy, the power of driving link input and driven member output are equal-sized, promptly

By formula (2-3) as can be seen the rotating speed of driven member be directly proportional with the product of driving link rotating speed and torque, be inversely proportional to the torque of driven member.And the product of driving link rotating speed and torque is consistent with input power, and the output torque of driven member and load are consistent, and promptly the planet gear stepless speed variator can be according to the variation stepless change on one's own initiative of input power and load.
Pay special attention to be the design speed changer velocity ratio must be variable, promptly maximum transmission ratio can not equate greater than fastest ratio.If equate that speed changer is merely able to do not have stepless shift function with the certain gear ratio transferring power.For example two single planetary rows that gear ratio is identical or two identical double planet wheel rows of mixing of gear ratio, any two groups of elements of the same name connect respectively or make one, another is organized one of element of the same name and makes one of driving link and make driven member, and the rotating speed of driving link and driven member is always identical.
