撓み噛合い式歯車装置

Japanese Patent JP5256249

B2

PROBLEM TO BE SOLVED: To enable a gear device to increase load torque by restraining deflection stress due to deformation of an external gear as much as possible and avoiding tooth profile interference of an internal gear with an external gear due to deformation of the external gear.SOLUTION: In the flexible meshing-type gear device 100 which is provided with the internal gear 130A for reduction, the external gear 120A and an exciter 104, a shape of the external periphery of the exciter 104 is constructed to connect by turns the first arcuate portion FA which forms the external gear 120A and the internal gear 130A for the reduction as condition of meshing and at the same time is configured as an arc, the second arcuate portion SA with radius of curvature r2 which is smaller than that of the first arcuate portion FA and the third arcuate portion TA which has radius of curvature r3 larger than that of the first arcuate portion FA and forms the internal gear 130A for the reduction and the external gear 120A as condition of non-meshing while at the same time in a connecting portion of the first arcuate portion FA, the second arcuate portion SA and the third arcuate portion TA, and tangent lines T1, T2 at the first arcuate portion FA, the second arcuate portion SA and the third arcuate portion TA are common to all, respectively.
