Description
Technical field
The present invention relates to the field of speed reducer, be specifically related to a kind of just taken turns by the double-deck eccentric wheel of adjustment, fixing just wheel and rotating between the quantity of relevant teeth, to determine the synchronous cycloid reduction device of reduction speed ratio and rotation direction.
Background technique
In tradition, motor reduces its rotating speed to improve torsion through retarder.Retarder is according to different application, and common retarder has planetary reducer, harmonic speed reducer and cycloidal reducer.
But retarder exists narrow limitation, be presented below:
For planetary reducer, it is restricted to: 1) reduction speed ratio of single planetary reducer is about 2-10.To improve reduction speed ratio, then just must can be reached effect of high reduction speed ratio by superposition planetary reducer; Although planetary reducer superposition can improve reduction speed ratio, the planetary reducer after superposition can cause the shortcomings such as positioning precision variation and cost increase; And, 2) due to the invertible operation pattern (namely output terminal and input end can be used alternatingly) of planetary reducer, make planetary reducer not possess braking function; To this, when under the situation needing precise positioning (such as stopping), power source must, by an extra brake apparatus, could allow planetary reducer stop; But relative to the power source not adopting brake apparatus, brake apparatus can increase the weight of power source, volume, cost and power consumption.
For harmonic wave speed reducing machine, it is restricted to: 1) harmonic wave speed reducing machine adopts flexbile gear, and flexbile gear is in deformation process over a long time, have the problem that metal is tired, moreover, because the wall thickness of flexbile gear is thinner, when harmonic wave speed reducing machine bears high torsion, flexbile gear is by fault of easily splitting.Above-mentioned reason, all will directly or indirectly cause shorten the working life of harmonic wave speed reducing machine; 2) harmonic wave speed reducing machine be limited to flexbile gear deformation quantity and cannot reach less than 30 reduction speed ratio, therefore, harmonic wave speed reducing machine is not also suitable for the product of low reduction speed ratio; And, 3) harmonic wave speed reducing machine is limited to the factor that flute profile modulus can not unconfinedly reduce, therefore reduction speed ratio cannot be promoted to more than 300, and therefore, harmonic wave speed reducing machine is not also suitable for the product of high reduction speed ratio.
For traditional cycloidal reducer, its shortcoming is: 1) cycloidal reducer is designed to the eccentric shaft of two or three, engages to promote double-deck eccentric wheel with just taking turns; But eccentric shaft uses bearing designation smaller (namely eccentric shaft is thinner), and therefore, after long-time use, eccentric shaft easily damages; 2) reduction speed ratio of cycloidal reducer is by just wheel and eccentric wheel determine, the formula of its reduction speed ratio is the eccentric number of teeth/(number of teeth of the eccentric number of teeth-firm wheel), to reach the high reduction speed ratio of more than 300, only can increase the eccentric number of teeth, or the number of teeth reduced just between wheel and eccentric wheel is poor; But in the confined space, the eccentric number of teeth cannot constantly increase or number of teeth difference constantly cannot be contracted to less than 1.Therefore, cycloidal reducer will reach the reduction speed ratio of more than 300, is actually very inaccessible; And, 3) cycloidal reducer possesses braking function, is applicable to being applied in irreversible operator scheme.Therefore, cycloidal reducer is not suitable for the application in invertible operation pattern.
In view of this, the present invention proposes a kind of synchronous cycloid reduction device, to solve the disappearance of known techniques.
