Embodiment
In order to make object of the present invention, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Embodiment
Refer to Fig. 1 and Fig. 2, the invention discloses the poor sub-retarder in footpath, comprise the poor subrack 1 in footpath, fixing female shell wheel 2, the poor son 3 in footpath, differential shell wheel 4, wherein: poor sub 3 structures in footpath include poor Combined wheel 31 and poor son wheel 32, the poor subrack axle 11 in footpath.
Implementation detail: the poor sub-retarder working principle in footpath, if poor subrack is input speed axle, the poor sub-interlock in poor subrack and footpath, poor Combined wheel and fixing female shell wheel engagement driving that footpath is poor sub, fixing female shell wheel is to maintain static moving form to exist, can obtain the linear velocity of input speed reaction on poor Combined wheel, the poor sub poor Combined wheel in footpath is structure as a whole or fixed combination with poor son wheel, angular velocity corresponding to the linear velocity of poor Combined wheel is the same with poor sub-wheel speed, the son wheel of being on duty is nibbled transmission with differential shell wheel, and differential shell wheel is the same with the linear velocity of poor son wheel; Fixing so female shell wheel is driven by the poor son in same footpath with differential shell wheel, between fixing female shell wheel and differential shell wheel, speed difference is linear differential between the poor sub poor Combined wheel in footpath and poor son wheel, fixing female shell wheel is to maintain static moving form to exist, and the speed of differential shell wheel is linear differential between poor Combined wheel and poor son wheel.
The poor sub-retarder reduction speed ratio computing in footpath and reduction speed ratio scope, establishing poor Combined wheel diameter is Ma, poor sub-wheel diameter is Mb; In the time of Ma=Mb, reduction speed ratio=Ma/(Ma-Mb)=∞, be infinity, in the time of Ma=2*Mb, reduction speed ratio=Ma/(Ma-Mb)=2; In the time of Ma=Mb/2, reduction speed ratio=Ma/(Ma-Mb)=-1.Conclusion is: the Combined wheel of being on duty be greater than poor son wheel footpath difference be positive output speed and input speed in the same way, the Combined wheel of being on duty is less than poor son wheel output speed for reverse, reduction speed ratio scope, in poor Combined wheel and poor son are taken turns than twice value, contain all deceleration ratio completely, the poor sub-retarder in footpath is the retarder of a any reduction speed ratio.
Fixing female shell wheel of the poor sub-retarder in footpath and the setting of the differential shell gear teeth, it is independent engagement mode separately, can have modulus value or tooth pitch separately, modulus value or tooth pitch can and be determined according to technique and output torque requirement separately; Superelevation reduction speed ratio is that differential shell wheel monodentate is poor, and the number of teeth of differential shell wheel, except 1, also can this be worth the anti-poor sub poor ratio of diameter in design footpath that pushes away.
Footpath difference of the poor sub-retarder in footpath is set, and fixing female shell wheel and differential shell tooth number are set the integer value of the multiple that meets the poor subnumber in uniform footpath, and the poor Combined wheel in footpath is the same with poor sub-gear teeth initial angle, is footpath difference substructure the same; Otherwise footpath poor son palpus offset deviation Combined wheel and poor son wheel initial angle, to meet meshing condition separately.
The input and output shaft of the poor sub-retarder in footpath is set, and in the time that differential shell wheel is set as defeated axle, and obtains output speed in the same way; While setting fixing female shell wheel for defeated axle, can obtain reverse output speed; The poor subrack axle 11 in footpath can define and the poor subrack combinations of directions in footpath because obtaining the forward and reverse of output speed, and the poor sub-retarder in footpath is that symplex structure design, assembly and production are more superior flexibly.
The above, the present invention is annotation and the enforcement that utilizes speed of related movement to obtain speed change theory, the mechanism that part is equal to roughly the same does not look with the present invention; Change face shaping, unfold combination etc. not depending on scratching format invention with the present invention; The present invention is only embodiment preferably; protection scope of the present invention is not limited to this; any be familiar with those skilled in the art the present invention disclose technical scope in, the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
