Title:
ROCKING INTERNAL GEAR TYPE INSCRIBED MESHING PLANETARY GEAR DEVICE
Document Type and Number:
Japanese Patent JP3963587
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To maintain durability of eccentric body shafts and their bearings as same as possible in the case that a construction in which the load of the eccentric body shaft differs each other is adopted.
SOLUTION: A rocking internal gear type inscribed meshing planetary gear device includes a casing 101, an external gear 121 arranged in the casing 101 as an output member, plural eccentric body shafts 110, 111 arranged at the outer circumference side of the external gear 121 and rotatably supported by the casing 101, eccentric bodies 110A, 111A put on the eccentric body shafts, and a rocking internal gear body 112A which meshes with the external gear 121 and through which the eccentric bodies 110A, 111A are built. The rocking internal gear 112A is rocked and rotated by rotation of the eccentric bodies 110A, 111A to rotate the external gear 121. At lease one of the plural eccentric body shafts 110, 111 is given a different diameter from others in such a rocking internal gear type inscribed meshing planetary gear device. The diameter of the eccentric body shaft 110 is larger than that of the eccentric body shafts 111.
