Invention content
Retarder of the present invention includes at least at least one set of input gear group Zi, at least one set of output gear group Zo.It is defeated
It includes at least one input shaft to enter gear set, and one has revolution Ω simultaneouslyi1With rotation Ωr1Gear G1.Output gear group packet
It includes at least one output shaft and one while there is revolution Ωo1With rotation Ωo2Gear G2。
In the input gear group Zi, there are one or more input shafts；When with 1 input shaft, remaining input shaft can lead to
Structure design is crossed to be fixed on shell.Input gear group ZiIn, pass through internal gear, external gear, bias by one or more input shafts
Wheel or other mechanisms cooperate, and drive G1Gear realizes rotation and revolution.The output gear group ZoIn, by internal gear, outside
Gear, eccentric wheel or other mechanisms cooperate, by G2Output is realized in driving.
Preferably, ZiIt can be used and ZoThe power transfer path of mirror image.
Usually, input angular velocity ωi1, ωi2With G1Relationship between gear is expressed as
Zi(ωi1, ωi2) = G1(Ωi1, Ωr1, ri1, rs1)
Wherein, ri1、rs1Respectively G1Rotation radius and revolution-radius.That is, ZiInput speed and G1Revolution angle speed
Degree, autobiography angular speed, revolution-radius and autobiography radius all connect each other.Only there are one tools when input shaft, by ωi1Axis is as power
Input shaft, ωi2Axis is connected with shell, at this point, ωi2=0。
Output speed ωo1, ωo2With G2Relationship between gear is expressed as

Preferably, ZoWith ZiUsing mirror image power transfer path, and ZiOnly there are one power input shafts, another is fixed on
When shell, ZoAlso only there are one power output shafts.
The G1With G2The gear forms such as gear with parabolic shaped tooth, cycloid gear can be used.Preferably, G1With G2Using parabola
Gear, and there is same or similar modulus.
The gear G1With gear G2It keeps moving synchronously by the connection of connected or mechanism, and G1And G2Revolution-radius and
Autobiography radius has a small amount of difference, that is, meets
(Ωi1, Ωr1, ri1, rs1) = k(Ωi2, Ωr2, ri2, rs2)
Wherein, k is a constant value vector.
As k=1, G1With G2It is identical, ωi2=ωo2=0.At this point, reduction ratio η=ωi2/ωo2For infinity.
ControlkThe variation of value so that ωo2≠ 0, and using the axis as output, by G2Drive ωo2Output shaft compensateskIt is small
G caused by amount variation1With G2Amount of exercise difference ensures G2With G1Move synchronously, realize scheduled reduction ratio.
In this method, due to ZiWith ZoThe same or similar kind of drive can be used, avoid big retarding than in design process
Extreme dimensional ratio, structure can be simplified, and the reduction ratio of retarder can be greatly improved.
The present invention proposes a new class of retarder, can be widely used for Design of Speed Reducer field；The retarder reduction ratio is big,
It is related to that gear link is few, and structure is more compact, and different realization methods, realization method spirit can be used according to requirement of engineering
It is living.
